David meets up with Oliver Schurmann in the old abandoned quarry that's the new home for Mount Venus nursery. After 25 years in a walled garden, the new location is a magical place reclaimed by nature. Adam Frost chooses his bulb of the month (Crocus tommasinianus) and a dream comes true for some residents in Culmore near Derry as a brand new allotment site gets going. Also on the programme, Amy Kelly on getting your seeds going early and Colin Agnew joins David in studio to talk about creating a home for alpines and they answer listener questions.
