Head of Lettuce Problems – When it comes to those first barbecued burgers and spring salads, crisp, sweet head lettuce is a must-have. Head lettuces, such as iceberg and romaine, need chilly temperatures to thrive and are best grown in the spring or autumn in most climate zones.
Gardeners in warmer areas with fewer cold spells may discover that their lettuce crops are unable to produce a head. If you want to know why my lettuce isn’t producing heads, you’ll need to understand the causes of the lack of lettuce production. In most places, head lettuce difficulties may be avoided by utilizing transplants or planting in the autumn rather than the spring.
I like all things salad, so I plant a lot of lettuce to ensure that I have a constant supply. Because it’s such a simple plant to cultivate, you’ll usually receive a good harvest the majority of the time. Unfortunately, you will also encounter several common lettuce difficulties that may cause your crop to be ruined, or at the very least, compel you to throw away a large portion of it.
Many tips of the art for identifying and dealing with lettuce issues have been developed over the years, and I’d like to share them with you. Let’s get started if you want to get the most out of your lettuce crop.
My lettuce is not Forming Heads, and I need help
Lettuce is a cool-season crop that will bolt or fail to form heads if daily temperatures are above 70 degrees Fahrenheit during the growing season (21 C.) Head lettuce difficulties may vary from slug and snail damage to loose heads, despite the fact that it is a reasonably simple crop to manage. Pest issues are simple to deal with, but only certain climatic circumstances may result in the production of heads. Provide temperatures and site circumstances that favor the creation of heads on your lettuce crop if you are experiencing no head formation.
Some of the Reasons why Lettuce Heads are not Served
Lettuce grows best in soil that is rich in organic matter and has excellent drainage. After working in a layer of organic matter and tilling to a depth of at least 6 inches, sow the seeds in the early spring (15 cm). Sow seeds directly into prepared soil at a location where the plants will get indirect light and will be shaded from the sun’s fiercest rays as much as possible. Spread a thin layer of fine dirt over the seeds, about 1/8 inch (3 mm) thick, and keep it mildly damp.
Plants that have been seeded outdoors should be spaced at least 10 inches (25 cm) apart. If you don’t thin your plants, they won’t have enough area to grow large enough heads to support themselves.
When plants are grown late in the season, they will be exposed to higher temperatures, which will impede the creation of tight heads. If you have a regular issue with lettuce not producing heads, consider planting in late summer. When the temperature drops in the autumn, developing seedlings might produce crisp heads because of the colder environment.
Getting Rid of No Head Formation
Lettuce is very sensitive to heat, and exposure to high summer temperatures or a prolonged period of high temperatures might prevent them from developing properly. Head lettuce is better suited to northern latitudes, although gardeners in milder areas may grow the green with good success.
Start seeds inside in flats and transplant them outside at least a month before the anticipated high temperatures. Spacing is another issue that affects the formation of tight-forming leaves in head lettuce. Plant the seedlings 10 to 12 inches (25–31 cm) apart in rows 12 to 18 inches (31–46 cm) apart in a sunny location in the garden.
Other head of Lettuce Issues to Consider
Head lettuce requires low temperatures and shorter day lengths in order to develop the finest heads possible. The plant will bolt if it is planted too late in the growing season (forming seed heads). When the temperature rises over 70 degrees Fahrenheit, the greens become bitter as well (21 C.).
