Leek in a Zone 11 season
Zone 11 gives about 365 frost-free days. Leek needs roughly 120 days from transplant. That leaves about 245 days of slack, so there is room for a late start or a second planting.
How to grow leeks
Start seeds indoors about 8 weeks before planting out. Transplant into a deep hole and hill soil up the stem as it grows, to blanch the white shank. Leeks grow slowly, so keep them weeded and watered.
