Lettuce

Water: Keep evenly moist in well-drained soil to prevent bolting.
Light: Full Sun or Partial Shade

Fertilizer: Onions are pretty self-sufficient, but apply Ferti-lome Gardeners Special every 3-4 weeks will encourage root and bulb growth.
Plant: Plant onions starts or sets in rows spaced according to how large the finished onion will be.
Harvest: Onions are ready to harvest when their tops begin to turn brown and fall over and the skin feels papery to the touch. Loosen the onions from the dirt with a spade or fork and lift out. Allow the onions to rest in a cool, dry place with good air circulation to allow them to cure for better storage.
