Hi Sven,

My fingers are far from green, but with a new Victorian house, I'm looking to plant a new tree in the back garden. We already have a cherry blossom, and we want something that compliments it. We need advice on what tree has deep roots rather than those that spread, as it will be near a brick wall. Also is it safe to plant now or do I need to wait until spring?

Thanks,

LouBou

Hi LouBou,

I know it seems obvious but you will have to choose a tree that is the right size for your space, an English Oak in a small garden, for example, is never a good idea. Trees can also cast a lot of shade so consider carefully where it is planted and what is planted under it, any shade-hating plants will not survive!

Think about what features you want, for example flowers, autumn colour, fruit etc. You'll also need to decide which shape tree is best. Do you want a tree with a rounded canopy to create shade in a hot garden? Or a tall tree with a narrow habit that will give a more formal appearance?

You need to consider your neighbours when planting trees; how will it affect their right for light, and also any structures in their garden as you are responsible for any damage. It is also vital that you don't plant trees too close to the house because they can cause subsidence. Trees remove a lot of water from the soil and therefore can cause cracks in the soil, which means that any vibrations such as large lorries going by can then causes expensive problems.
