planting trees in clay soil
I've recently bought potted dwarf trees, Apple, Pear, Sweet Cherry each about 1m-1.5m tall. Dug large holes for them which then fill up an inch or two with water at the bottom and clay soil is sodden! I've heard about root rot and I don't want to destroy the trees. I've received mixed advice from suppliers/other gardeners from sympathy to sharp sand to horticultural grit to leave until drier (but when will that be!!? And how long can I leave them in their pots?) We live in the north-east (new to area).
