I have offered to help my very elderly neighbour prune her plum greengage and cherry trees. I dont think any of them have been touched for years! The plum and greengage trees are at least 20ft tall! How much hieght can I take off without killing them? All the trees seem to have 1 central trunk with other smaller trunks growing around it! Basically dont know where to start!!Ever wished you had kept your mouth shut!! Any advice would be most wecome! Jane

Hi Jane, some good advice in the thread 'Grass and soil thrown around plum trees' posted by Knightquest. I would,not advise a major prune now but would cut out any diseased or crossing branches. Object is to let light and air circulate the branches. With a large  established tree aim to prune about a third at a time.

cut any of this year's growth by half as soon as possible, no winter pruning for plums and cherries because of silver leaf disease they can get. Advice from a master pruner I've learnt recently
