HI @tz1ppy

Welcome to the Garden Ninja forum. Before I answer, I would urge you to read my detailed article on fake grass and why as a garden designer, I never have nor will use it. It also details the myriad of problems and issues with using such an unsustainable and damaging material.

A quick list of the problems with artificial grass are:

• Fake grass can't be recycled
• It doesn't stop weeds or moss from taking up a home in the 'artificial grass'
• It gets incredibly hot in summer
• It kills off pretty much all wildlife underneath and above it
• It requires constant cleaning as nothing can permeate it
• It's killing off wildlife wherever it's installed

Fitting fake grass issues:

Installing fake grass isn't as simple as unrolling it and there you go.

Fake grass needs to be installed on top of a layer of compacted MOT, ie rubble. Similar to laying a base for paving.

It needs a wacker plate and levelling by contractors usually.

The fake grass then needs to be glued, pinned and adhered to this to stop it rippling or getting blown up.

All of which is expensive, and don't forget weeds will still emerge on its surface. It's far cheaper to fit real grass and mow it every 10 days in summer than picking off leaves and animal waste from fake grass (which also can stink in summer unless disinfected).

Weeding through gravel:

The best way to weed gravel gardens is with a hoe not weed killer which again spills off and kills not only weeds but other plants. Enters our water courses and damages more than just plants. Have a look at my weeding guide here to help.

A better alternative to fake grass:

As ethical gardeners, a better way to deal with front gardens or awkward spots is to use a mix of wild fuss-free plants and even some weeds. We must remember the impact, both positive and negative we can have on the planet through our gardening choices.

Why not keep the gravel garden, weed it with a hoe and then plant some wonderful evergreen fuss free plants. Here's a list to get you started:

• Carex
• Galium odoratum (sweet woodruff)
• Pachysandra
• Bergenia
• Thyme
• Lavender

Hope that helps with whatever decision you choose.

Happy gardening.

Yes, you’ll need to remove the gravel and weeds first for a smooth installation. Here’s a step-by-step guide:

1. Remove Gravel & Weeds – Clear out all the gravel and pull up as many weeds as possible. If you leave uneven gravel underneath, it could affect how the grass sits.

2. Apply Weed Killer – Use a strong, pet-friendly weed killer (like glyphosate-based ones) to prevent regrowth. Allow a few days for it to take effect.

3. Install a New Membrane – Lay down a high-quality geotextile weed membrane to stop future weed growth while allowing drainage.

4. Add a Base Layer – A compacted sub-base of MOT Type 1 (hardcore) and sharp sand (approx. 3-4 inches deep) creates a stable foundation. Compact it well with a wacker plate.

5. Lay the Grass & Secure It – Roll out your artificial grass, trim the edges, and secure it with galvanized nails or adhesive on the perimeter.

6. Brush in Silica Sand Infill – This helps keep the grass in place, improves drainage, and prevents flattening.

With this method, you’ll have a smooth, long-lasting artificial lawn with minimal weeds! Hope that helps—good luck!
