Most young plants will be happy if you need to relocate them.
As soon as your deciduous plants have dropped all their leaves and are dormant, that’s when you can move them. It may be that they’re growing in the wrong place or they’ve grown too big for their boots, so now’s the time to help the thrive somewhere else.
Large, mature specimens over five years old may not survive the transplant, and renovation or removal may be the solution. Some plants don’t like root disturbance, such as magnolias or roses, but young plants of most things will be happy to move.
Give the soil around the plant a good long soaking before you start digging, and after planting, water really well in dry spells, but not in frost. Mulch with compost and feed with a general fertiliser in spring. Evergreens should be left till March or April before moving.
