Reply To: Espalier Pears against a 2m tall, old brick wall

[ElleGee]

Andrew, I planted two espalier apples three years ago against the wall of an 1700’s stone building. It was exactly as you describe – full of all sorts of rubble. I planted bare rooted one year old whips into holes as Charles recommends (just a little bigger than the roots required) and the trees have done very well. Each year in autumn I mulch with well rotted manure.
