Romaine Lettuce Seed Planting Information:

Romaine 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 romaine lettuce, or cut the entire head about 1" above the soil. A new head may grow.

BR - Black Rot

Scientific Name: Xanthomonas campestris

Type: Bacterium

Black Rot is a disease that affects the growth of arugula, broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale, kohlrabi, mustard, radishes, rutabaga, Swiss chard, tomatoes, turnips, and watercress. It survives in warm wet weather and affects cabbage throughout the United States. It is spread from one field to another field by water and wind. The bacteria can infect seeds and young seedlings. Young plants infected will turn yellow, drop lower leaves, and may die. Once the plant is infected there is no rescue treatment since the infection is systemic. Symptoms include the yellowing of the leaves in v-shape or wedge-shaped patches and blackening of the internal vein. Usually only a few of the outer leaves are affected. Since the disease is spread by water, anything that can be done to reduce leaf wetness will help reduce the spread of the disease. Water the plants in the morning, instead of the watering in the afternoon or night, so the leaves have time to dry before sunset. Increase space between the plants to maximize air flow and drying of the leaves. The disease is favorable when temperatures are 75-95 F and rain, heavy fogs, and dew are present. The bacteria does not spread when temperatures are below 50 F or during dry weather. Plan on using a 3 year crop rotation and avoid planting in the same location, year after year, as the disease can survive in the soil for two years. Treating the infected area with fungicides can help manage the disease. The primary source of bacteria of black rot is infested seeds and in infested transplants. The best option is to use disease resistant varieties, disease-free seeds, and disease-free transplants.

BRib - Brown Rib

Type: Physiological Disorder

Brown Rib is a physiological disorder that affects lettuce. The disease cause dark brown to black streaks on the wrapper leaves first, then the discoloration extends to veins and ribs. The brown streaks along the ribs and veins of the leaves are often followed by soft rot. The cause is not proven, but it is thought to be heat stress and fluctuations of temperatures. Symptoms occur in the fields during warmest periods of the growing season. The best option is to use disease resistant varieties.

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.

We live in the southern part of Texas. We are currently growing 5 types of lettuce.  I don't know yet about how well the heads will form or how long until our weather gets too hot for lettuce, but I can tell you without a doubt, this lettuce is fantastic! I pinch off outer leaves daily, for sandwiches and salads, and it just can't be beat. It is way prettier than the picture they show on here.  Leaves as large as my hand, and super tender.  Not bitter like our iceberg and leaf lettuces.
