Test soil for adequate levels of nitrogen, phosphorus, and potassium.
Apply generous amounts of organic compost.

Keep soil moist and weed-free.
Reduce overhead watering once the plants have reached 4 to 6 inches in diameter to prevent leaf blemish.

Harvest by thinning or cutting outer leaves 1-2 inches above the soil before leaves turn yellow or the plant bolts.

With crops such as leaf lettuce, where it is the leaves you want to harvest, select a plant that takes a long time to go to seed.
Growing leaf lettuce cross-pollinates readily.

The flower stalk develops in the fall.
Once the stalk is mature, collect the seeds and allow them to dry for a day or so in the sunshine but bring them in at night to avoid dampness.
