I have a bunch of tomatos and peppers that i satrted from seed. They are all around 2" to 3" tall. I have 3 to 4 starts in each 1-1/2" square pod that sits on top of a wicking mat system. How do you know when it's time to transplant to the next size up container. I hope to save as many plants as possible when i do this. I didnt expect such a high germination ratio when i seeded the pods. This website is an incredible source of info. Thanks to you all!
I like to sow my seeds in open flats. Prick and pot up when they have 2 true leaves like gardenjester's rule. This way I'm not sacrificing or culling seedlings. Gives you a chance to plant them deeper also if they are leggy.
Well, ordinarily I also like to wait until they have the second pair of true leaves; the seedlings are getting a bit sturdier then. But your little plants are very crowded. I might go ahead and get them separated and give them more breathing room once they have the first pair of true leaves opened up.
I agree with all of the above: wait until they have their first true leaves and then to do the up-potting. You may want to consider burying the plant up to those true leaves so that it will develop a stronger root system. Depending on the plant, the berried stem will send out roots.
