Leeks Planting Program
Extend Your Leeks Harvest
Johnny's Leek Planting/Harvesting Program is designed to take the guesswork out of planting, allowing you to maximize yield and quality over the widest possible harvest window.
- First, use the chart below to choose varieties for planting by their projected sequential harvest slots: 1) summer; 2) late summer/fall; 3) late fall/winter; and 4) winter.
- Next, plant several leek varieties with different maturity dates at the same time.
- Then, harvest in succession. Each leek variety will mature in its appropriate seasonal slot from a spring planting. The less cold-tolerant leeks are faster-growing, and the more cold-hardy leeks are slower-growing.
