    Large conifers - prune or remove?!

    We bought a house, now the house is renovated we are thinking about the garden… we have never had a garden before, so will likely be a steep learning curve. The garden was very overgrown with brambles and ivy (which we are still battling) so there’s a lot of work to do. 

    There are some large conifers on one side of the garden along with a large holly tree which is pretty hidden by the conifers. I don’t want to unnecessarily get rid of trees but they do take up a lot of space, so we need to decide whether we should remove any or all of them. 

    am I right in thinking pruning the conifers wouldn’t make a significant size difference as they can’t be hard pruned? And if we got rid of one them and left one, would the side that has been covered by brown rather than green? Or could we get rid of the conifers but keep the holly tree and neaten it up? Would it even be possible to remove the conifers without damaging the holly tree? 

    Sorry this feels like a lot of questions but any advice greatly appreciated. I’ve attached a picture so you can see what I am talking about! 

    Hi @turnerrachel86

    Welcome to the Garden Ninja community and congratulations on getting your first garden - what an exciting journey you're about to embark on! Your question about the large conifers is absolutely spot on, and you're completely right to be thinking strategically about what stays and what goes before you start your garden design.

    Understanding Conifer Pruning Limitations

    You're absolutely correct that pruning conifers won't make a significant size difference if you're hoping to dramatically reduce their footprint. Most conifers simply cannot be hard pruned back to old wood because they won't regenerate new growth from older, brown branches. Unlike deciduous trees that can bounce back from severe pruning, conifers have very strong apical dominance, meaning they focus their energy on growing at the tips of branches rather than producing new shoots from older wood.

    This means you can only trim back into the current year's green growth, which typically gives you just a few inches of reduction rather than the dramatic size reduction you'd need to reclaim significant garden space. If these conifers are dominating your garden and blocking light, pruning alone won't solve your space issues.

    The Hidden Holly Dilemma

    Regarding your concern about the holly tree - this is actually a really smart observation. If the holly has been growing in the shade and shelter of the conifers for years, removing one or more conifers could expose it to conditions it's not used to. The side that's been shaded will likely look quite brown and sparse initially, as holly tends to develop dense foliage only where it receives adequate light.

    However, holly trees are remarkably resilient and adaptable. Once exposed to more light, that sparse side will gradually fill out with new growth, though it may take a couple of seasons to look balanced again. Holly is also excellent for wildlife, providing both shelter and winter berries, so it's definitely worth keeping if possible.

    Strategic Removal Options

    The good news is that it's absolutely possible to selectively remove conifers whilst preserving the holly, though you'll need to be quite careful about the process. The key is to work with a qualified tree surgeon who can assess the root systems and plan the removal to minimise damage to surrounding plants.

    Consider removing the conifers in stages rather than all at once. This allows the holly to gradually adapt to increased light and wind exposure, reducing shock. You might start by removing the conifer that's casting the most shade on your potential garden space, then assess how the holly responds before deciding whether to remove additional trees.

    Crown Lifting as an Alternative

    Before committing to complete removal, consider whether crown lifting might be an option for some of these conifers. This involves removing the lower branches to create more usable space underneath whilst maintaining the tree's height and much of its screening value. Crown lifting can dramatically increase the feeling of space and light whilst still providing privacy and wildlife value.

    This technique works particularly well with mature conifers and could give you the best of both worlds - more garden space at ground level whilst maintaining some of the established structure and benefits these mature trees provide.

    Making the Final Decision

    Given that this is your first garden and you're dealing with an overgrown space, I'd lean towards removing at least some of the conifers to give yourself more design flexibility. Large conifers can be incredibly thirsty and will compete aggressively with any new planting you want to establish. They also tend to make the soil quite acidic with their needle drop, which limits your planting options.

    My suggestion would be to remove the conifers that are most problematic for your intended garden use, keep the holly (with some light pruning to improve its shape), and perhaps consider keeping one conifer if it provides useful screening or wildlife habitat. This gives you space to create the garden you want whilst maintaining some mature structure and ecological value.
