lettuce just stopped growing!

[hellicat]

Hi everyone I need some help with my lettuce (arugula). My seeds germinated and have grown about 6 inches. They also have those first two leaves. But they haven't grown at all in the last 2 weeks and they look really limp. They've actually all just flopped onto the soil. I don't think it's over or under watering because my other plants like herbs, tomatoes, and cucumbers are coming up pretty well.

Should I just give and start again? Or is there hope for these little guys? Thanks for any advice!

Give it a little more time. You could start some others in the meanwhile just in case. Plants grow in spurts, a couple weeks of increased growth and a couple weeks of rest, or so I have found with several types of plants. Just when you think they have given up, they can turn around and surprise you. You might take a different approach if they are in different containers. Take one and let it dry out more, continue on with watering the other as normal. See which helps.

If the first two leaves are the cotyledons or seed leaves, the plant will take off when the reserves in those are depleted. You will notice this as they start to shrink, shrivel, or brown up at the tips. Usually though the first set of true leaves will come up before they are depleted. I've never grown arugula so I am speaking in general terms of plant growth. Hope this helps. Also if the starting containers are real small (as in a starter tray, 2" pot, yogurt cup, etc) and the roots have hit the bottom, moving them up into a bigger container, might help.

They are waiting to be picked and eaten at 6 inches. Mine grow outside, new ones are just beginning to grow, they will grow taller if not picked, then they will Flower then form pods containing Seed and reseed themself and start the process over again.

Are these seedlings that are growing inside?

Have they grown as large as the pot will allow?

Have they deplete the nutrients in the soil?
