Crisphead Lettuce Seed Planting Information:

Crisphead lettuce can be grown anywhere as long as you have composted soil. Lettuce grows best if planted indoors and transplanted outdoors in early spring. Lettuce does well in composted soil. It does not do well in clay soil. Make successive plantings. Plant your seeds indoors 3 to 6 weeks before setting outside. Lettuce will better tolerate heat if plants are well thinned and air can circulate around them. Spring planting should occur as soon as soil can be worked, and fall planting done around June or July. Plants grow 2 - 10" tall.

Soil Requirements:

Requires fertile sandy soil in a well drained location in the garden. Apply much and grass clippings, or straw around base of plant.

Water Requirements:

Keep soil consistently moist, but not waterlogged. Water well during dry and hot spells. Water in the morning only, on the side of the plants and not directly on the leaves.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Apply Miracle Gro periodically.

Harvest Tips:

Pick outer leaves of crisphead lettuce, or cut the entire head about 1" above the soil. A new head may grow.

TB - Tip Burn

Type: Physiological Disorder

Tip Burn is caused by inadequate transport of calcium to rapidly growing tissues. It has caused severe loses to growers in the United States and Europe. It affects Brussels sprouts, cabbage, cauliflower, kohlrabi, and lettuce. Uneven rainfall and watering, high temperatures, high humidity, windy conditions, dry soil conditions, and rapid growth are all factors. Tip burn consists of a breakdown of the plant tissue near the center of the head and develops as the crop approaches maturity. The inner leaves of heads of cabbage are affected, often without external symptoms. The inner leaves turn dark brown, then to a black color. Symptoms can extend from a few small brown spots on interior leaf edges, to large areas of the leaf turning brown and eventually decaying. Secondary rot caused by bacteria can follow tip burn and heads of cauliflower can be severely affected. No completely effective controls are known, but excessive soil moisture and insufficient soil moisture have both been suspected as contributing to a calcium deficiency. Managing irrigation can regulate and control plant growth and calcium deficiency. The best option is to use varieties resistant to tip burn.
