Beginner level

If I said you could grow vegetables easily without having the backbreaking task of digging over your beds each year, would you believe me? You may have heard of the 'No dig' gardening method and think its too good to be true. I caught up with Charles Dowding on one of his 'No dig' masterclasses to find out why it provides bumper crops, is better for the environment and will save you from backache!

Quick Answer

No dig gardening means covering weeds or grass with cardboard and a thick compost mulch instead of digging or tilling the soil. You plant straight into the compost, top it up once a year, and let worms and soil life do the cultivating for you. It is quicker to start, kinder to your back and produces healthier, more productive soil than traditional digging.

The grow your own movement has really taken off over the past decade here in the UK, along with no dig gardening. You only have to look online to see Instagrammers and social media full of grow your own tips. After all, who doesn’t want to be able to grow the food that they put on their table? It certainly opens up a huge variety of different organic vegetables to choose from and can be a fraction of the cost of buying them from the supermarket.

No dig gardening enables you to quickly establish a vegetable bed without hours of digging and soil improvement. Many people have turned towards growing their own fruit and vegetables for a variety of reasons in recent years: you can grow a wider variety of produce, you know exactly where your food is coming from, and the very act of gardening brings a heap of mental health benefits.

Even if you are a beginner gardener or short on time, no dig is an easy way to take your first tentative steps to productive gardening. Mainly because no dig gardening reduces effort and the time needed to prepare soil before you start to plant. Part of this movement is down to the expertise of the man who first popularised it in the UK, Charles Dowding.

I advocate that no dig gardening is perfect for the beginner new to growing vegetables. There’s no need to create the perfect tilth (a fancy word for nice soil texture) or break your back slicing through hard, weed-infested soil. In fact, no dig frees up time for the new gardener to enjoy one of the main benefits of gardening, learning to grow.

So, first things first, let me explain how no dig gardening works and why it is perfect for the beginner gardener.

What is no dig gardening?

Put simply, no dig is exactly as it sounds. It’s a means of gardening without digging over the plot repeatedly each year. It’s based on the principle of minimising disturbance to the soil, leaving it in a far less disrupted state.

Over decades, the advice to dig over your soil to cultivate and improve it has been used across allotments and gardens countrywide under the somewhat false impression that this promotes healthy soil and the removal of weeds. This cultivation involves constant digging and turning the soil over, adding plant feed and other soil improvers, fiddling with and changing the soil structure yearly.

In fact, the opposite is true based on Charles Dowding’s detailed practical research and results. Charles has spent over 30 years experimenting with no dig and dig gardening, with startling results on his vegetable patches. His work has revealed that intensive dig cultivation is actually harmful to the soil, promotes weed growth and leads to a reduction in crop production. Not only that, it requires a huge amount of manual labour, leaving you with less time to actually harvest your bountiful crops.

With a no dig garden, you’re only disturbing the soil to plant your seedlings and undertaking some light hoeing. Followed by a compost mulch once a year, and you’re good to grow.

No more forking, double digging or pulling your back. For the beginner gardener, I often hear complaints that gardening is too much effort or that they don’t have the time. If you’re not huffing and puffing fighting your soil, you’re saving both effort and time. Want to grow your own and save time doing it? Then no dig is for you.

How does no dig gardening work?

The no dig methodology relies on careful preparation of your growing area first, with the removal or smothering of weeds (more on that below), followed by a thick mulch of cardboard, then compost. Once you have prepared your site in the first year, you’re good to grow.

The principle of no dig is that each year, you’re topping up your raised beds with additional compost, light weeding and plenty of harvesting. You never need to dig again. You simply mulch each year once you have harvested your vegetables.

Starting a no dig garden can be broken down into 3 main steps

  1. Preparing the site: mulch and weed smothering
  2. Enriching the soil with a thick compost mulch, without digging it in
  3. Each year, topping up this compost, again as a mulch

Charles makes a key point that you’re not feeding the vegetables directly, but feeding and improving the soil. This is a complete about-turn from most gardening guides on providing nutrients for plants through liquid feeds and fertiliser.

Charles is a firm believer that simply adding organic matter in the form of compost is all you need. This allows the nutrients to be released from the soil without adding extra potions and cocktails, saving time and money in the process.

The great thing for beginner gardeners is that you only need a few key ingredients, most of which you may already have: cardboard (any will do, obviously no plastic, and try to remove staples to save your hands), compost, whether homemade, bought in or well rotted manure collected from a local farm, and a fork or spade, not to dig with, but to move the compost onto your new beds.

Charles Dowding: the no dig pioneer

If you’ve read anything about no dig gardening online, you’ll already have come across Charles Dowding’s name. He’s been experimenting with no dig on his market garden at Homeacres in Somerset for over 40 years, running side-by-side trial beds of dug and undug ground and weighing every single harvest to prove the difference. It’s rare in gardening to get proper long-term data like this, which is exactly why I wanted to spend time with him directly rather than just reading about the method secondhand.

What struck me most about spending the day at his Marbury Hall workshop was how relaxed the whole method is in practice. There’s none of the anxiety that comes with traditional cultivation, worrying about getting the tilth right or whether you’ve dug deep enough. Charles’s approach strips gardening back to two things: don’t disturb the soil, and feed it well from the top. Everything else in this guide comes from watching him work and applying it in my own beds since.

Starting a no dig garden in 6 steps

Preparing the site is key to a no dig garden. If you fail to prepare, prepare to fail. Charles explains that the basis for starting your garden is to use cardboard to smother any existing weeds or grass, and then dress the soil so it is ready to plant.

There are a few key steps to starting your no dig vegetable or herbaceous plots. I’ve broken them down into 6 key steps below for beginner gardeners. These steps will allow planting in year one, and it’s far faster than the dig method.

Step 1: Cut out any bramble crowns if present

The first step is to remove any pervasive weeds such as brambles, big docks or thistles if possible. Then leave all other weeds in situ and ignore them. The next steps sort these out without needing to break your back weeding.

Step 2: Prepare the site by layering thick cardboard

The next step is to start layering cardboard over the site that is to become your vegetable beds and any pathways between them. This is the smother layer that will ultimately block out the light and kill off any weeds that were once there.

Creating a no dig garden by layering cardboard

Step 3: Weigh the cardboard down with stones or bricks

Using bricks, logs or even heavy stones, weigh the cardboard down while preparing the ground. These weights first stop the cardboard from blowing off, but also help anchor it temporarily. This keeps light from getting into the soil, which stops weeds from growing and helps smother them.

Step 4: Add a thick layer of compost

Once the cardboard and weights are in place, add a 6-inch thick layer of compost to the cardboarded area. The ideal compost is either homegrown or peat free compost. The better quality the compost, the better your results, as this compost feeds your vegetables, especially during the first year or two while the soil underneath gets broken up by earthworms and bacteria. In year one, you rely on the compost as the growing medium and the food for your plants and vegetables.

Garden Ninja explains adding a compost layer for no dig

Step 5: Leave the cardboard in place until it has fully broken down

Any weeds are smothered by this point, and you’re left with clean beds ready to plant into the compost. Leave the compost and weights in place for the first year, ideally, to let the bed establish. Keep the edges topped with compost and weed-free. A clean edge, such as EverEdge, can help keep the bed tidy and easy to mow around if it sits at ground or lawn level.

Step 6: Yearly top up of compost

Top up your compost each year to enrich the soil for the following year’s planting. Add another 4 to 6 inches of compost, as it gets used up each year by hungry vegetables and needs replenishing. The most considerable criticism of no dig gardening is that it’s resource intensive, given the amount of compost you need each year. It can quickly become expensive if you don’t make your own.

Tools you need for no dig gardening

Part of the appeal of no dig is how little kit it actually demands. You won’t need a rotavator, a spade sharp enough to slice through turf, or the sort of back brace some allotment neighbours seem to require. Here’s what I actually reach for.

Removing perennial weeds in a no dig garden

The great news with no dig is that there’s no need to remove weeds before laying your cardboard and mulch down. This is the main issue that puts off new gardeners. Weeding. No one enjoys it; it’s time-consuming and can feel relentless. Many new gardeners tell me they initially find it hard to tell a weed from a real plant.

Have a look below at some of the contenders you want to get rid of. No dig minimises the occurrence of weeds, and those that do appear can be easily hoed off from the loose topsoil structure. As the soil is free and relatively soft, you don’t have to dig down to get them out.

The only exception is brambles, and Charles recommends cutting out the woody crown first before laying the cardboard and mulch.

Common perennial and annual UK garden weeds

The usual offenders of perennial and annual weeds. Notice their different root types and leaves.

Most perennial weeds will be weakened and then killed off by the cardboard and mulch. However, there are always exceptions, such as Ground Elder, Bindweed and Mares Tail, all of which require some continued observation and intervention.

I use a Hori Hori for light weeding, whereas Charles recommends an oscillating hoe to scrape weeds off lightly once they rear their heads through your compost layer. Because the new top compost layer is loose, these weeds are far easier to remove when they do appear. So while you’re cursing them, remember it’s far easier than bending over and manually digging each one out.

Charles Dowding removing perennial weeds

Charles above is rarely seen holding a spade, showing the need to level the site if there are any large lumps or bumps. Here he’s removing a lump from the back wall that leans towards the wheelbarrow. If left, the compost and moisture would follow this fall line and cause a potential dry spot.

Layering cardboard for no dig

Cardboard helps prepare your no dig beds by smothering weeds and blocking light, which stops weeds germinating. This is a vital step for all no dig gardens, as it starts the process of killing off weeds and improving soil structure without digging them up.

The cardboard and compost dual layer excludes light and acts as a barrier for weeds, meaning they either die back or are prevented from growing in the first place. What’s really great about this is that it’s completely organic, using cardboard, which is recycled by the soil. The key here is to exclude light, which kills off the weeds.

There’s no need for chemicals, toxic concoctions or back-breaking digging to get rid of them. The cardboard and mulch do all of this for you.

In his books, Charles states you can use a plastic membrane for this first phase to kill off weeds, but it must be removed afterwards. You may have read about my fight against plastic in the garden, so I’d never recommend using weed membrane as a permanent solution. It doesn’t biodegrade and tends to break into tiny microplastics that can enter the food chain.

I prefer cardboard as it’s easier and recyclable. It needs to be overlapped by 2 to 3 inches so weeds don’t pop back through. I love this part, as many of us in the UK have cardboard recycling bins, meaning we can reuse this ourselves, or even, with permission, use neighbours’ waste cardboard.

See how the cardboard in this small space is overlapped and forms the base for the no dig patch? On the left, you can see rows of lettuce already planted out.

Adding compost to no dig beds

Charles recommends a 10mm or less sieved compost as ideal, though homemade green waste compost or even well-rotted manure will suffice. A top tip is to use your lumpier compost on the bottom and finer compost nearer the top.

The aim is to top dress the soil so worms and other organisms can break the compost down into the soil beneath. This also means you can plant directly into the top layer of compost even if you have poor or impacted soil. No need to soil test, dig in organic matter, or any of that. You can start planting straight away in these beds.

Layering a thick compost mulch on top of cardboard

The key is adding a thick layer, 3 to 6 inches initially and then a further 2 inches each year. A light sprinkling will have little to no effect, so go big with this one. It may be best to order a few tonnes of compost to get started, even for a smaller bed. You’ll be surprised how quickly it’s incorporated into the soil, meaning your no dig bed is working.

Compost is going to become your best friend, as it propels your no dig garden to bumper harvests and minimal weeding.

Careful attention needs to be paid to the edges of your beds. This is the weak point where perennial weeds can take hold again, and you may even find yourself more heavily mulching these compared to the rest of the site.

How to plant in a no dig bed

Planting couldn’t be simpler. Charles uses a long handled dibber, think of a brush handle without the brush, so there’s no more awkward bending or kneeling.

He recommends growing your seedlings in modules to save time pricking out, and only makes enough excavation for the plant to fit in snugly, again minimising disturbance. He also buries his seedlings deeply, covering some of the stems.

Housekeeping is another strong message in no dig. By keeping a clean, tidy plot, removing damaged leaves and doing regular light hoeing, you reduce the chances of pests taking a bite of your crop. Charles recommends cropping your beds multiple times a year, leaving less space for weeds to grow and maximising your harvest returns.

Best plants for your first no dig bed

Once your bed is prepared, the obvious question is what to actually put in it. Fresh compost is a remarkably forgiving growing medium, so almost anything settles in well, but some plants make far more of that first year fertility than others. I’ll cover a handful of quick, reliable vegetable picks below, then spend more time on ornamental plants, since no dig works just as well for a flower border as it does for a veg patch and this side of it gets asked about far less often.

Quick vegetable picks for year one

Fresh no dig compost is a remarkably forgiving growing medium, but some crops make far more of that first year fertility than others. These six are the ones I’d sow into a brand new bed without a second thought, each chosen because it does well in loose, rich compost rather than needing an established, settled soil structure underneath it.

Salad leaves

Salad leaves have shallow roots and give you a harvest within weeks, which is exactly the quick win a beginner bed needs. They don’t ask anything of the soil beneath the compost layer, so they’re the first thing I sow into any new no dig bed, often within days of the compost going down.

Courgettes

Courgettes are heavy feeders that thrive in the rich, loose compost of a first year bed and are almost impossible to get wrong. One plant will keep a family in courgettes all summer, and I’ve never once seen a beginner struggle with them in a well mulched no dig bed.

Broad beans

Broad beans go in early, fix nitrogen as they grow, and establish strong roots even while the compost underneath is still settling. That nitrogen fixing is a genuine bonus for a first year bed, since it’s quietly improving your soil for whatever you plant after them.

Garlic

Garlic cloves can be pushed straight through your cardboard and compost layer in autumn, no planting hole needed, and they’ll sit there quietly suppressing weeds all winter before emerging in spring. It’s about as low maintenance as a first year crop gets, and there’s something satisfying about a vegetable that does most of the work while you’re not even thinking about the bed.

Chard

Chard is remarkably tolerant of the settling soil in a new no dig bed, producing colourful stems and leaves for months on end. It’s a cut and come again crop too, so a single row will keep giving you harvests well into autumn without needing to be resown.

Kale

Kale is a hardy brassica that appreciates the steady moisture retention of a compost mulch and establishes strong roots in undisturbed soil structure. It’s also one of the few crops that keeps producing right through winter, which matters when the rest of a new bed has gone quiet.

For an even fuller year one vegetable list, including potatoes, runner beans, squash, spring onions and more, my lawn conversion guide covers thirteen tried and tested options in detail.

Ornamental plants that thrive in a no dig border

This is where I think a lot of no dig guides fall short, since almost every one of them assumes you only want to grow vegetables. In reality, I convert flower borders to no dig for clients just as often as I do vegetable beds, and the same cardboard and compost method works brilliantly for herbaceous planting. The plants below are ones I return to again and again for a freshly converted no dig border, since they all establish well in rich, loose compost without needing the soil underneath to be perfect from day one.

Hardy geraniums

Hardy geraniums, or cranesbills, are about as forgiving as border plants get. They spread readily through loose compost, tolerate the slightly uneven moisture of a first year no dig bed, and knit together quickly to help suppress any surface weeds that do sneak through. I use them constantly as a front of border filler on new client gardens, since they earn their keep within a single season.

Sedum (Hylotelephium)

Sedum, now more correctly called Hylotelephium, is one of the few border plants that actively prefers not to be pampered. It copes with the slightly variable drainage of a fresh compost bed far better than most perennials, and its fleshy leaves store enough moisture to shrug off the odd dry spell while your bed’s structure is still developing. It also flowers late, giving pollinators a food source right through into autumn.

Astrantia

Astrantia is a plant I really think is underused in UK borders, and a no dig bed is the perfect place to establish it. It likes the moisture retention that a good compost mulch gives you, sends up its pincushion flowers reliably through summer, and once settled will happily self seed a little through the loose surface layer, filling gaps without any help from you.

Foxgloves (Digitalis)

Foxgloves are a brilliant choice for a new no dig border because they’re biennial, so they spend their first year quietly building a rosette of leaves in the compost before throwing up their tall flower spikes the following summer. That gives your bed a properly dramatic second year display for very little effort, and they’re superb for bees, which matters to me given I keep bees myself.

Hyssop

Hyssop is one I’d choose over a bulb for a brand new bed, since a freshly made no dig bed usually isn’t deep enough yet for anything that needs to root down properly, like alliums or tulips, and bulbs planted too shallow into loose compost tend to heave, rot or simply fail to establish in year one. Hyssop instead roots into the top few inches, is drought tolerant once settled, and its spikes of blue flowers are a magnet for bees, which I’m always glad of given I keep my own hives.

Penstemon

Penstemon rounds off my list because it flowers for months on end, from early summer right through to the first frosts, which makes it excellent value in a border that’s still finding its feet. It’s also notably slug resistant, which matters more than usual in a new no dig bed, since slug pressure tends to be higher than normal in year one while predator numbers are still building up.

Why no dig is great for beginner gardeners

If you’re not already convinced by Charles’s method, which I’m sure you will be, here are some other beginner friendly benefits of the no dig approach, drawn from what I’ve actually seen work in my own beds and in client gardens over the years. And while most of this guide has focused on vegetable growing, since that’s where Charles’s own trials are, everything below applies just as well to ornamental borders and flower beds. I use exactly the same cardboard and compost approach when I’m converting a border for a client, not just a veg patch.

1. You’re not constantly fighting weeds to start

You don’t need to suffer the defeat of digging over a plot all weekend to find it covered in weeds the next weekend. I’ve watched more than one client give up on a vegetable patch entirely after that exact cycle repeated itself three or four times in a season. With no dig, you’re simply covering the weeds with cardboard to smother them, so that demoralising loop never gets the chance to start. It’s as much a psychological win as a practical one, since nothing kills off a new gardener’s enthusiasm faster than feeling like the weeds are winning.

2. No dig is fast to establish

There’s a huge time saving here, and it’s front loaded, which matters when you’re new to this. A weekend with cardboard and a trailer of compost gets you a plantable bed, rather than weeks of forking over heavy clay before you’ve grown a single thing. That speed means more time for beginners to enjoy and learn from the actual growing process rather than weeding and struggling through soil preparation, and it builds confidence early, right when a new gardener needs it most to keep going into a second and third season.

3. No dig is excellent for small gardens or urban gardening

You can start really small. Even a 1m by 2m bed can be made no dig in less than a day, and I’ve built exactly this size for clients squeezing a first vegetable patch into a courtyard garden with no spare ground to speak of. No dig works with any sized garden, big or small, and because there’s no need for machinery access or room to manoeuvre a rotavator, it suits tight urban plots and awkward side returns just as well as an open allotment.

4. No dig is easy for beginner growers

The skill level to start a no dig garden is very low. Layering cardboard and spreading compost is all it takes, there’s no technique to get wrong the way there is with double digging or building a proper tilth. That low barrier to entry means more of your time and energy goes into the parts of gardening that actually keep people hooked, learning about growing from seed, choosing your crops and working out what suits your soil and aspect, rather than getting bogged down in soil preparation before you’ve even sown anything.

5. You can stop using shop bought plant feeds and fertilisers

No need to apply fertiliser or follow complicated plant care rules once your bed is established, since the compost mulch is doing that job continuously rather than in the occasional dose a liquid feed provides. That means you can reduce man made synthetic fertilisers and start growing organic crops in year one, and it also cuts out a whole category of ongoing spend and shopping trips that new gardeners often don’t budget for when they’re costing up a vegetable patch.

Synthetic plant feed

6. Beginner gardeners have a higher chance of success growing

There’s less chance of failure thanks to improved growing conditions, since nutrient rich, free draining compost is a far more forgiving medium than whatever your native soil happens to be. This avoids you needing perfect soil to start with, which I think is one of the most underrated benefits of the whole method. Plenty of gardens I’ve worked on have heavy clay or thin, stony ground that would take years of digging and amending to become properly productive, and no dig sidesteps that entirely. You can also walk on your soil without compacting it, since the compost is far more forgiving and the lack of digging means it keeps a more robust, open structure underneath.

The no dig method is straightforward for new gardeners who want to grow quickly, especially on an allotment if you’ve taken over a new plot and need to get it under control fast, since you’re not spending hours weeding and digging before you can plant a single crop.

Drawbacks of no dig gardening

While no dig gardening has numerous benefits, there are also some drawbacks to consider. It’s not all easy gardening and rainbows, unfortunately, so let’s look at the downsides so you’re fully informed before you commit a weekend and a trailer load of compost to it.

i) Initial set up time

Converting a traditional garden bed into a no dig system requires initial effort and time, and it’s worth being honest about that rather than pretending the whole thing is effortless from day one. Building up layers of organic matter and mulch takes some doing, especially starting from scratch, and you’ll need to find a good amount of cardboard to start a no dig allotment or garden. I’ve had clients underestimate just how much cardboard a full allotment plot swallows up, so start collecting it from a few weeks out rather than trying to source it all in one trip to the recycling centre.

ii) Cost of materials

Implementing a no dig system often involves buying organic matter, cardboard, compost, mulch and other materials to build the layers, and this is the part that catches people out most. These costs may be offset by reduced labour and maintenance over time, but they’re still worth budgeting for properly, especially for large garden areas. The main ongoing cost is the tonnes of compost needed each year, and if you’re not making enough of your own, that bill doesn’t go away once the bed is established, it simply becomes an annual one rather than a one off.

iii) Limited rooting depth

No dig gardening relies on layering organic matter on top of the soil rather than tilling it in. While this promotes soil health and microbial activity, it may limit how deep plant roots can penetrate, at least in the first year or two while the compost layer and the soil beneath it are still integrating. Some deep rooted vegetables or plants may not thrive as well in a no dig system straight away, though I’ve generally found this evens out once the bed matures and earthworms have opened up channels down into the ground below.

iv) Potential for weed seeds

While no dig systems aim to suppress weeds by smothering them, there’s still a chance that weed seeds present in the materials used may germinate and grow, particularly if you’re using municipal green waste compost rather than a well made peat free brand or your own well rotted material. Regular maintenance, such as mulch replenishment and hand weeding, may be necessary to manage weed growth. It also doesn’t stop surface weeds appearing from windblown seed landing on top of your bed, so it isn’t entirely weed free as many claim, and I’d be doing you a disservice telling you otherwise.

v) Dependence on outside inputs

No dig gardening often requires the addition of external organic matter, compost and mulch to maintain soil fertility and structure, at least until your own composting system is producing enough to cover your beds. Depending on the availability of these materials locally, gardeners may need to source them from outside their garden, leading to a dependence on external inputs that traditional digging, for all its faults, doesn’t create in quite the same way.

vi) Slow soil improvement

While no dig gardening improves soil health and structure over time, the process may be slower compared to traditional tilling, which physically breaks up compacted layers in one go rather than waiting for worms and biology to do it gradually from the top down. It can take several seasons for the soil to fully benefit from the no dig approach, especially in areas with poor, heavily compacted soil to start with, so manage your expectations for year one and judge the method properly by year two or three instead.

By weighing up these drawbacks, you can make an informed decision about whether no dig suits your garden and circumstances. Looking for more grow your own tips? Then why not follow my plastic free gardening tips for sowing seeds?

Common problems and solutions

No dig isn’t problem free, and there are a few frequent issues gardeners run into when starting new beds this way. Any new bed in its first year or two throws up something to deal with, no matter how diligent you are, so here’s what to expect and how to fix it.

ProblemCauseSolution
Increased slug or snail activityMoist mulch creating ideal habitatReduce mulch near vulnerable crops, use copper barriers, handpick regularly. Eases as predators establish
WaterloggingPoor drainage or heavy soil beneathBuild the bed 20 to 30cm high, improve drainage, give the soil time to develop structure
Nutrient deficienciesInadequate compost quality or quantityIncrease compost rates, use well rotted manure, be generous with the initial layer
Perennial weed breakthroughGaps in the cardboard suppression layerRepair gaps immediately, extend suppression period, stay vigilant in year one
Slow decompositionCold weather, dry conditions or thick materialsKeep it moist, choose the right season, use finer materials where possible
Annual weed pressureWeed seed bank from previous cultivationRegular removal while small, maintain surface mulch, patience over two to three seasons
Surface compactionFoot traffic or not enough organic matterAdd more compost, create defined paths, keep foot traffic off the beds themselves

Slug problems commonly increase during the initial conversion, and it’s the complaint I hear most from gardeners in their first year. It settles down in year two and beyond as predators such as ground beetles and centipedes colonise the bed. In the meantime, encouraging birds with feeders and water sources helps keep numbers down, and copper tape around vulnerable seedling pots buys you some breathing room while predator numbers build up.

Slugs and snails in no dig beds usually turn up because of the wet cardboard and damp conditions they enjoy. Choosing slug proof plants is a good way to reduce their impact on your hard work in the meantime, and a roll of copper tape around your most vulnerable seed trays is a cheap, reliable backup.

If waterlogging is a recurring issue on heavier soil, building your bed up with a simple timber or composite raised bed frame solves it far more reliably than trying to improve drainage from within an existing no dig layer.

What to expect in year 2 with no dig beds

Year two is when a no dig bed really proves itself. The dramatic transformation of year one gives way to steadier, more subtle improvements, better soil structure, fewer weeds, better yields and noticeably easier maintenance. This is when all the initial effort starts paying you back, and it’s the period that answers the “does no dig actually work” question better than anything I can tell you in year one.

Your soil will be noticeably darker, more crumbly and far easier to work than in year one. Earthworm numbers typically double, with castings visible on the surface, and you’ll likely spot white mycelium threads when lifting mulch. That’s not a disease, it’s a sign of a thriving fungal network doing exactly what it should. The soil itself smells sweet and earthy rather than dead or sour, moisture retention improves so you’ll water less often, and beneficial insects like ground beetles and centipedes start colonising the bed and keeping slug numbers down naturally.

Weeding drops off noticeably too. Annual weed pressure typically falls by close to half compared to year one, since the seed bank brought up by any previous cultivation is depleting fast, and what does appear tends to pull out effortlessly from the loose compost. Most gardeners find a weekly session on a small bed drops from twenty minutes to closer to ten. A good hori hori makes short work of what’s left.

Yields usually improve too, most noticeably in root crops, which produce straighter roots and easier digging thanks to the improved structure. It isn’t perfection though. Beds still need regular attention, weeds decrease but don’t vanish, and slugs, aphids and caterpillars remain part of gardening life. Watering is still needed in dry spells, and individual beds can perform differently depending on how well year one’s suppression and compost layer went down. Persistent waterlogging or a perennial weed reappearing are the two things worth acting on rather than waiting out.

Converting an existing lawn to no dig?

Everything above covers the philosophy and the general method. If you specifically want to turn part of your lawn into a no dig vegetable or flower bed, including exact depths, timings and how to handle stubborn grass, I’ve got a full dedicated guide for that here: How to Start No Dig Gardening Beds on Top of Lawns and Grass.

FAQ on no dig gardening

Does no dig gardening actually work?

Yes. Charles Dowding has run side by side dug and undug trial beds at Homeacres for decades, weighing every harvest, and the no dig beds consistently match or outperform the dug ones while needing far less labour. I’ve seen the same result in my own beds since visiting him.

Can you plant straight into a no dig bed?

Yes, once the initial cardboard and compost layer is down you can plant directly into the compost from day one. There’s no need to wait for the cardboard to fully break down before you start growing, though for lawn conversions I’d give it a season if you can.

What are the disadvantages of no dig gardening?

The main drawbacks are the ongoing cost and volume of compost needed each year, a slower initial set up than simply digging a bed over, and a slightly limited rooting depth for deep rooted crops. None of these are dealbreakers for most gardens, but they’re worth planning for.

What is the best soil or compost for a no dig garden?

Charles recommends a well rotted, finely sieved compost, homemade if possible, or good quality peat free compost bought in. Use lumpier compost as your base layer and finer compost on top where you’ll be sowing or planting.

What if I already have an established set of raised beds?

You can convert existing raised beds to no dig straight away. Stop digging or forking them over, clear any weeds by hand rather than turning the soil, then top dress with 2 to 3 inches of compost each year. There’s no need to start from scratch, the no dig principle simply becomes how you maintain the bed going forward.

Summary of no dig gardening

No dig can save gardeners an awful lot of wasted time, as you simply don’t need to dig over your veg and flower beds each year. By adding a rich compost mulch annually, you can completely remove the need for lots of back breaking ground cultivation.

Charles has demonstrated how even a tiny space can become a productive area in the garden. His website is jam packed full of hints, tips and a lively forum, so why not check it out.
