When To Thin Lettuce Seedlings

When should I thin out my lettuce seedlings?

Once the seedlings are large enough to handle, you’ll need to ‘thin’ them, reducing crowding in the row. Thinning your plants gives them space to grow to larger leaves and dense hearts.

How big should seedlings be before thinning?

Seedlings should have at least two pairs of true leaves and be about 3 to 4 inches (8-10 cm.) tall before thinning. Evening hours are a good time to thin seedlings as the cooler temps and darker conditions make it easier for the remaining seedlings to bounce back from any stress they may have received.

How tall should lettuce be before thinning?

The best approach is to plant seeds in a row, then wait until sprouts reach a few inches in height; most leaf lettuces should be thinned to about 4 to 6 inches apart, but check the information on the seed packet to confirm the desired distance.

What happens if you don’t Thin seedlings?

Thinning seedlings helps them develop and grow stronger and faster. Seedlings not thinned have small stems and a leggy appearance. When seedlings grow in a tight cluster (crowded plants) they fight for light and grow spindly.

How do you thin seedlings without killing them?

Should you thin lettuce plants?

Can you plant lettuce close together?

Generally, you should space plants far enough apart so that they can grow to full size. However, many gardeners plant lettuce much closer together, preferring to harvest leaves continuously before they reach full size. The plants adapt to their spacing.

Can you replant thinned seedlings?

When the seedlings have developed their second set of true leaves, it’s time to transplant or thin them. If you don’t need many plants, you can thin them in place: just pinch or snip off the excess seedlings, leaving the remaining ones spaced about 2 inches apart. Water the transplant right away.

Plants that grow too close to each other compete for the same sunlight, water and soil nutrients. The first effect seen is competition for light. Overcrowded plants begin to grow upward to receive light, rather than developing a fuller, bushier silhouette.

What do you do when you have too many seedlings?

If you get more than one in one pot, just cut them off without disturbing the main seedling. Be very gentle with the seedling and do not disturb the roots. I know, it is hard to cut off a healthy seedling, but planting them together will bring you less than one healthy seedling would.

Seedlings aren’t able to store water for very long, so they need soil that is constantly moist. This means watering them a few times a day, depending on how quickly they dry out. Test your seedling’s soil with the end of a finger to about an inch deep. If the soil is dry, your seedling needs water.
