How much light are they getting,what are the avg temps,and what kind of soil are you using?

What zone are you in? Just about anywhere, it's late to have seedlings so small. You might want to continue with the plants you've got as an experiment if you've got the room (figure out a way now to provide them with adequate light, so that you have more experience for next year), but buy some seedlings as insurance so that you get tomatoes this summer.

ColleenConnie:

I too am new to this. My plants were spindley. Very good posts in my thread search for I NEED LOTS OF HELP.

Anyway short answers:
Once the seeds pop out, put them in light. Most use a shop light with 2x fluorescent bulbs. Window sills might generate more Spindley plants.

Cure to spindley plants is a small fan. Hit them 3x a day or as I did all day. and they should grow a stronger stem.

Good Luck

My seedlings are just now getting their true leaves & they're the size they always are at this time of year. I never start my seeds until at least the first week of April.

No grow lights...I start them in soil I've brought in from the garden...I keep them in the utility room where the furnace keeps them warm. When they sprout, I sit them out during the days as long as the wind isn't blowing, it's not raining, & it's above 45 degrees.

I always have a huge crop of mater's...soooo...I say, you've got plenty of time to give them more time...depending on your zone.

Plant spindly plants as deep as possible and you we be fine

ColleenConnie in the future try this. Only fill the container you are starting your seeds in 1/3rd full. That way you can add soil later to help support the plant. As an added bonus the plants will grow roots along the stem after you have filled the container.

What a simple solution thisisme!

I have some seedlings that will get some more soil to now. Luckily I did not fill them to the top.

Should I wait until the seedlings are larger? Some are onlt 3 - 4 inches tall. All have true leaves.

thanks!
