Like every living thing, lettuce needs to ensure its continued reproduction. This is why lettuces “bolt” – the plants begin to grow upwards, producing less leaves and eventually blooming. How do I stop my lettuce from bolting? 3 ways to delay bolting lettuce: 1) Grow bolt tolerant cultivars. Certain varieties of lettuce, spinach, radicchio, cabbage, […]

Even if you can’t grow it in the deep winter, you can still plant in late summer and have many a lettuce harvest in fall. How late in the season can you plant lettuce? If you are buying transplants (small plants) from a garden center or nursery, you may plant between 2 weeks before your […]

Keep Lettuce Plants Well-Watered Water evaporating from the soil provides natural cooling. Water your lettuce plants every day—and even more often if it is extremely hot and dry. The lettuce leaves are comprised mostly of water and will desiccate and wilt in strong sunlight and dry soil. How do I keep lettuce longer in the […]

Heat-tolerant lettuces: ‘Ice Queen (Reine des Glaces)’ (Summer Crisp) ‘Little Gem’ (Romaine) ‘Marvel of Four Season’ (Butterhead) ‘New Red Fire’ (Leaf Lettuce) ‘Parris Island’ Cos (Romaine) ‘Red Sails (Leaf Lettuce) ‘Rouge d’ Hiver’ (Romaine) Salad Bowl Blend (Leaf Lettuce) What is the most heat tolerant lettuce? Butterhead lettuce is usually known for being among the […]

Destroy infected plants immediately and keep lettuce foliage dry to minimize the spread of lettuce drop. Chemical controls aren’t usually necessary in the home garden. Instead, move the lettuce to a better garden bed, plant in a raised bed or grow it in containers with good drainage. How do you revive a dying lettuce? Lettuce […]

Most lettuce varieties thrive during cool weather, growing best when temperatures are above freezing but below 75 degrees Fahrenheit. Warmer temperatures slow leaf production and can cause wilting. What temp is too cold for lettuce? Lettuce may cope with light freezing and even one or two hard freezes, but once the thermometer reads 25°F or […]

1) Choose heat tolerant varieties Lettuce is a cool-season vegetable, but some varieties have been bred to better tolerate hot weather. Here are some of the most heat-resistant varieties that I’ve found: Romaine – Jericho, Parris Island. Batavian – Nevada, Sierra, Tahoe. Can lettuce get too hot? Lettuce may bolt in response to the stress […]

If you notice a clear pattern of light-green leaves in your vegetable garden, the first possibility to consider is nitrogen deficiency. Nitrogen is considered a limiting nutrient because plants need large amounts relative to the natural supply in most soils. Why are my plant leaves light green? The most common reason for leaves turning pale […]

Finally, tipburn is not harmful. In the case of commercial growers, it does reduce salability, but for the home grower, simply snip off the browning edges and consume as usual. What causes tip burn on lettuce? Cause of tipburn Tipburn is a feature of rapidly growing summer lettuce (but it can also occur in spring […]

Even with all the answers, there doesn’t appear to be a mention of recommended lux/lumen for lettuce. Approximately 80-100k will be adequate. Too much more than that (150-200k) and you’ll risk having too much which if I recall correctly can cause lettuce to flower (due to the heat concentration). How many watts of light do […]

For high-light plants like tomatoes you will want to achieve around 40 watts per square foot for optimal growth and fruit production. For low light plants, and small leafy plants like herbs and lettuce, you will only need to achieve about 25 to 30 watts per square foot. What kind of light does lettuce need […]

In many reports5,6,7,8, red–blue LEDs were demonstrated to be more suitable for lettuce cultivation. Red and blue lights have the greatest impact on plant growth because they are the major energy sources for photosynthetic CO2 assimilation. Can lettuce grow in artificial light? Keep lettuce plants in a location where they receive six to eight hours […]

Avoiding inner leaf “tip-burn” in lettuce Fertilize with adequate amounts of calcium. First check that adequate calcium is supplied in the nutrient program. Calcium foliar sprays. Modify the growing climate. Avoid antagonistic effects from other fertilizer nutrients. Avoid high soluble salts. Select resistant varieties. Why does lettuce get tip burn? Cause of tipburn Tipburn is […]

“The growth characteristic results for the two lettuce cultivars grown under various ratios of blue to red LEDs confirmed that red LED serves as a major light source that improves lettuce growth rate,” the authors said. What color light does lettuce like? In many reports5,6,7,8, red–blue LEDs were demonstrated to be more suitable for lettuce […]

Lettuce grows remarkably well under LED lighting. Today’s LED lighting is an effective, productive and energy-efficient tool to consistently increase production. Furthermore, vary- ing light intensity and wave length has been shown to direct nutrition and flavor in crops ranging from broccoli to blue- berries. Does lettuce grow well under grow lights? Take a walk […]

For best results, place the planters under a light for 24 hours a day. You can also cover your pot with a clear plastic bag and place it in a south-facing window. Check the soil moisture daily and water as needed. Depending on the type of lettuce planted, seeds will begin to sprout in 7 […]

Moist, but not wet, soil with good drainage is key. When your lettuce is thirsty it will wilt in the sun. Give its roots a drink right away along with a splash of cool water on the leaves to keep them happy on hot days. Use row covers to shade the leaves, and mulch to […]

ANSWER: Tomato feed isn’t optimal for nourishing lettuce plants because blends for tomatoes are designed to especially promote fruiting. What is the best feed for lettuce? Feed lettuce plants every two weeks with a balanced water soluble or granular fertilizer, such as a 10-10-10 or a 5-5-5, diluted to half strength. Look for a fertilizer […]

Dried grass clippings make an excellent organic mulch for lettuce, as do compost, leaves and straw. Do not let mulch touch the lettuce leaves, especially if either one is wet. Mulch could stick to the leaves and become nuisance to remove later. Should I mulch around my lettuce? As with anything in the garden, lettuces […]
