Why are my lettuce seeds not germinating?
Lettuce Seeds Germination Time If the soil is too warm, dry, or wet, or if there’s no light, it will inhibit germination. So, if your lettuce seeds aren’t growing, then check the temperature, light, and moisture levels.
How long do lettuce seedlings take to grow?

How do you successfully germinate lettuce?
Growing a lettuce garden The seeds germinate in temperatures as low as 40 F (4 C) but its ideal germination and growing temperature is between 60 and 65 F (16 to 18 C). To grow great lettuce, find a site that offers at least six to eight hours of direct sun.
Does lettuce need sunlight to germinate?
Lettuce seeds must be exposed to light to grow into seedlings. You can sprinkle them on soil or vermiculite and then cover them with a thin layer of soil or vermiculite. Carrots: much like lettuce, to get carrot seeds to germinate, expose them to light by sprinkling them on the surface of the soil.
How often do you water lettuce seeds?

What month do you plant lettuce?

Why do seeds germinate faster in the dark?
Most seeds germinate underground, so their first stages of growth are naturally in the dark. Seedlings can grow for a certain time in the dark as they have a limited chemical energy store in their cells. Once these energy stores run out, they need light exposure to produce their energy using photosynthesis.
What temperature do lettuce seeds germinate?
Lettuce seed will germinate at 35°F, but optimum germination is 70 to 75°F. If the plants are sufficiently hardened, they will withstand freezing. Repeated exposure to subfreezing temperatures, however, can seriously injure or kill the crop. Lettuce has a relatively high water requirement.
Can you overwater lettuce?
Too much or too little water can spell disaster for lettuce plants at every stage of growth. Insufficient moisture will cause lettuce seeds and seedlings to fail, while too much water will contribute to fungal and bacterial growth that can kill young seedlings.
Should you water lettuce every day?
Keep Lettuce Plants Well-Watered Water your lettuce plants every day—and even more often if it is extremely hot and dry. The lettuce leaves are mostly water and will desiccate and wilt in strong sunlight and dry soil. Lettuce roots tend to be shallow, so frequent watering is more important than deep watering.
Why is my lettuce not growing?
Insufficient soil moisture or overly wet soil can both result in poor growth and wilting. Lettuce suffering from drought stress wilts quickly and fails to put on new growth. Wet and soggy soil causes the plant’s roots to drown and rot. Leaves may begin to yellow and wilt, or the whole plant may become stunted.
