Growers on the care of autumn leeks:

• Keep leek plants weed-free.
• Leeks thrive in well-loosened, moisture-retentive soil.
• Harvest best with a fork or spade to prevent the stems from breaking.
• Protect your leeks with insect netting against the leek moth.

When to transplant autumn leeks? Transplant autumn leeks between late May and early July. Water well after transplanting, especially in dry weather. Leek plants are not picky about soil type, as long as it is fertile and well-drained. They do appreciate a sunny spot. Traditionally, leeks are grown in open ground, but you can also grow them in large, deep planters or raised beds if you have limited space.

When to harvest leeks? You can harvest autumn leeks from September to December. Only harvest what you need for immediate use, as leeks cannot be stored for very long. Use a fork or spade to harvest so the stem does not break.
