How tall should seedlings be before thinning?
about 3 to 4 inchesSeedlings 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 often should I water seedlings?
once a daySeedlings should be watered once a day or every other day, depending on how much sun and heat they get. Remember that seedling roots are fairly close to the surface and they're growing in a small amount of media, so they don't need a deep soak the way larger plants do.
What happens if you plant too many seeds together?
Crowded plants not only discourage growth, they encourage pests and disease. Crowded seedlings shade each other from the sun. As they get larger, it only gets worse. Crowded root vegetables, including turnips, beets, and radishes, won't develop useable roots if they're crowded.
How do you separate seedlings without killing them?
Cut the weak seedlings off at the base – It's very important that you cut the stems off at the base, rather than pinching them out. And never try to pull the seedlings out of the soil while thinning. Doing that can damage the delicate roots of the others, which could end up killing them too.
Do all seedlings need to be thinned?
Ideally, you should thin seedlings once they've grown enough to judge which are the healthiest, and which are the weaker ones to be removed. However, don't wait to long. If several seedlings are competing for root space, they may have a tough start in life which leaves them permanently weaker.

How to tell if a seedling has true leaves?
Look for 1-2 sets of true leaves on each seedling. Seed leaves are replaced by true leaves as the seedlings grow. Look for leaves that match the adults, as seed leaves are more rounded and simpler than true leaves. Waiting for the true leaves to appear helps you pinpoint the healthiest seedlings to keep.
How many seedlings per section?
Aim for 1 seedling per section if they were started in cells or punnets. Often several seedlings are started in the same place to make germination more likely. Leave only 1 seedling in each cell or punnet to give it the best chance of survival.

Can you thin plants?
Learning how to thin plants isn’t difficult. However, not all plants handle thinning the same way. Those having fragile roots, like beans and cucurbits (melons, squash, cucumbers), should be thinned as soon as possible, before their roots have a chance to become intertwined with one another. Otherwise, the remaining seedlings may suffer from root disturbance.
Can you pull out root crops?
They can be gently raked to remove excess seedlings as well, though I prefer pulling them one by one to limit any damage. Root crops are a bit more sensitive to thinning and should be pulled out with extra care or even cut at the soil line. Again, depending on the plants and their mature size, spacing may vary.
When is the best time to thin seedlings?

You can also try to transplant the extras into separate pots, but you risk damaging the roots and stunting growth. This is another reason why I like to pre-sprout seeds. Then I only plant the seeds that sprout one per soil block or container…No thinning required.
