One of the mysteries of any new garden is the identity of the bulbs under the surface. By the second season, you will know. Those you wish to move or dispose of can handily be lifted now, while they’re in an obvious and manageable format. Dig down carefully-some will be deeper than you expect. Lift them out, tap off most of the adhering soil and move them to temporary quarters such as a loose trench in the kitchen garden. Make sure you label them and keep a notebook record, ready for final planting in the autumn.
