Many of our trees give a very good result when espaliered. The best trees for basic horizontal espaliering are pears, apples and cherries. This is because they are easy to pull branches downwards and train flat. Also they produce fruit on spurs, which works well for this sort of training, and ensures a good crop is set.
It is also quite possible to espalier a lot of other sorts of trees, including stone fruit (best done in a ‘fan’ shape), lemons, figs, quinces and persimmons.
