Although an Autumn Giant selection, Porvite is also well suited to growing at high density for the production of baby leeks. It has excellent resistance to bolting and to rust and the mature plants will stand in good condition for several weeks.
Leeks need a deep, well drained soil enriched with well-rotted compost or manure.

Plant 15cm (6″) deep.
