Pruning apple trees in February in London, good idea?
Yes the RHS (royal horticultural society) recommend pruning of apple trees during the winter. Less is more when pruning apple trees, too much pruning can, on the one hand “shock” the tree and on the other encourage more vigorous growth.
Keep pruning apple trees simple, remove deadwood, remove crossed, damaged and diseased branches. Try to make the tree hollow of branches, like an upturned umbrella, the fruit ripens in the sun and the moving air through the tree prevents pests and diseases.
London Tree Surgeons offer a full tree pruning service.
