You might not be surprised to find out that the most widely planted salad vegetable in the United States is lettuce.Considered a spring and fall crop, lettuce thrives when temperatures are between 60 to 70 degrees F. Many varieties reach maturity in as little as 30 days, and some can even be harvested much earlier as microgreens.From your garden beds to patio containers, these simple steps will give you a bountiful supply of crisp salad greens throughout multiple seasons.You can begin planting leaf, romaine and butterhead lettuce as soon as the soil can be worked in the spring.Head lettuce is usually started indoors or in a cold frame and transplanted in the spring after the last frost date.The ideal lettuce growing location for spring and fall 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.The addition of organic materials, such as compost or manure, will increase drainage, provide essential nutrients and improve your lettuce growing conditions.If you’ve had trouble with lettuce growth, consider purchasing a soil test kit.Lettuce seeds are often quite small and only require a planting depth of ¼ to ½ inch deep.Head lettuce is usually grown from seeds started indoors during warm weather for a fall garden.Avoid watering too often – overwatering leads to root rot, disease and stunted growth.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.If you notice your lettuce beginning to brown and curl, it could be suffering from a physiological condition known as tipburn.Romaine, also known as cos, forms tall, tight bundles of thick, sweet lettuce leaves.Green Towers, Valley Heart and Red Eyes Cos are all interesting romaine cultivars.Named after the subtle butter flavor, this mild lettuce adds a sweet touch to salads.Other areas can use modifications, such as cold frames, row covers and greenhouses to extend the growing season.Other gardening tricks to prevent bolting in warm weather include planting lettuce in shady areas, using mulch to cool the ground and conserve moisture, and providing a light mist of overhead irrigation to cool plants. .

How to grow lettuce: plant and care for lettuce varieties

Well, if you’ve ever eaten freshly picked homegrown lettuce you’ll know there’s a world of difference between the deliciously succulent leaves straight from the garden, and the sad, wilting specimens you might find in a supermarket.You can even be eating your own homegrown lettuce leaves before then if you harvest the edible young seedlings rather than discarding them as you thin your plants out.As lettuce plants prefer cooler temperatures it’s best to sow seeds outdoors from March to August.If you want to grow and harvest your lettuces in winter, you will need to keep them indoors in a warm, bright space, such as on a window ledge.The key is to barely cover the seed after sowing, just a very fine layer of compost is sufficient as light is needed for germination.If you’re sowing lettuce seed outdoors directly into the soil, prepare the ground first by digging in plenty of well-rotted garden compost.Once they are big enough to handle, thin the seedlings out to allow 10-20cm between plants and mulch around them with well-rotted compost to lock in moisture and keep them healthy.Garden writer and photographer Leigh Clapp favors the succession planting approach, saying: 'Lettuce will provide around five months’ yield from one seed packet.Now back in favor again after a few decades in the shadow of loose leaf varieties, it’s far easier to grow than you might imagine.Don McCulley of Swallow Tail Garden Seeds says, 'Oak leaf lettuce has tender and mild-tasting, deeply-lobed leaves that can be picked individually or allowed to form dense, ruffly heads.'.Cut and come again lettuce works particularly well in a shallow seed tray, or in a container on a window ledge where it's easy to pick whenever you need a few leaves.For all types of lettuce in containers, you just need to provide the right conditions as you would if you were growing them in the ground outside – fertile soil, enriched with moisture retaining compost, enough space between plants, protection from extreme heat (so they don’t bolt) and extreme cold (so the frost doesn’t kill them), and regular watering, of course.If none of those methods appeal, you could go into the garden in the evenings with a head torch, to collect slugs and snails and dispose of them or 'relocate ' them away from your crops.Hot, sunny conditions Although they need light to germinate, lettuce plants do better in part shaded areas of the garden.They prefer cool, moist soil and if the conditions are too hot and sunny the plants have a tendency to bolt, so bear this in mind when selecting your spot in the vegetable plot. .
