Impact Lettuce is a hybrid cultivar of lettuce with special features and qualities. This special variety is produced by Technisem and it is very much available in sachets of 5g.
Lettuce loves cool weather. Depending on the variety, lettuce germinates in temperatures between 40 to 85 degrees F. If you plant lettuce in successive plantings, with 10 to 14 days in between, you’ll have an extended harvest. The ideal lettuce growing location is in a spot that receives full sun. If you plan on growing lettuce during the summer or in warm planting zones, partial shade can provide protection from the heat. Growing lettuce from seed in late summer may require generous artificial shade to help cool the soil for germination. Once days become cooler, the shade can be removed to give plenty of sunlight to young lettuce plants.
How to Plant Lettuce
- Lettuce seeds are often quite small and only require a planting depth of ¼ to ½ inch deep.
- When sowing seeds directly into the soil, you should plant approximately 10 seeds per foot.
- Space your rows 12 to 18 inches apart.
- Thin leaf lettuce seedlings to 4 inches apart.
- Head lettuce is usually grown from seeds started indoors during warm weather for a fall garden.
- Transplant head lettuce in rows 12 to 18 inches apart with 10 to 12 inches between each plant.
Water Requirements for Lettuce
You don’t need lettuce to develop deep roots. In fact, you want to encourage leaf growth over rooting. Lettuce watering should be light, frequent, and consistent. The goal is to simply keep the soil moist. Avoid watering too often – overwatering leads to root rot, disease, and stunted growth.
Protecting Against Disease and Pests
Aphids can easily destroy a lettuce patch. Leaves curl and wilt as nutrients and water are sucked away. Aphids also spread disease and create mold issues. You’ll find these annoying little white pests hiding on the undersides of lettuce leaves. There isn’t a systemic insecticide to control aphids, so your best option is to encourage natural predators, such as lady beetles, or to apply a horticultural soap or neem oil.
How to Harvest Lettuce
Knowing how to harvest leaf lettuce is easy. You can either cut the entire bundle off at ground level, or you can remove just a few leaves at a time. Impact Lettuce is a butterhead lettuce and is easily cut off near ground level. If you harvest every other lettuce plant, you give the remaining plants room to continue growing.
