We moved into a new place(this time last year) with a peach tree in the garden. Must be at least 7-8 metres tall and quite unpruned over a long time. Last year it definatley had peach curl but never had the time to get anything done about any thing in the garden til now. Ive read that it needs treating with a bordeux mixture in Jan and Feb but think i'd be wasting more mixture because the tree is so unpruned. Its now starting to flower, is it ok to prune back now,taking some height off and make it a more sensible size to treat? or should i wait til autumn/winter?
