TULIPA
These bulbs are known to all – but not everyone is successful with them, year after year. If you have heavy clay soil, the bulbs are best lifted once the leaves have died back after flowering and dried off under cover. Then plant them back in October or November. The small species tulips are very useful for the rockery, and in most cases can be left in the ground.
