Crowing
Thank you. I started then in my AeroGarden. Moved them to cells, and then these pots. It all happened so quickly! I guess I'll need to look for larger pots. I don't have any, yet. Didn't expect this rapid of growth. I'm new to thisUsually I start my tomatoes in little peat cells (the little jiffy compressed tabs that expand with water). Once they have sprouted and have some good leaves, they get up-potted to a larger container - usually a clean quart yogurt container with holes drilled in the bottom. I mix up new soil for the up-potting, and I mix in some dry fertilizer to the soil in the bottom of the container. I trim off all lower leaves from the tomatoes, and when they are put into the container, I bury as much of the stem as I can. This causes more roots to form, as they will form roots off their stems when they are in a humid environment or touching soil. Yours look like they are at the perfect size to up-pot into some larger containers that are deeper. Then, once it is time to plant outside, I dig a deep hole (and/or angled trench), putting some Nitrogen fertilizer tabs in the bottom - Miracle Grow quick start tabs are easy to find, and cover these with a thin layer of soil. I plant the tomatoes deep, again burying as much stem as possible - either in a deep hole or in the angled trench. I think @TJAnonymous plants her tomatoes with a mix of shrimp, egg shells, and a few other things rather than a fertilizer.
Overall, tomatoes are pretty hardy - given the right nutrition. Good luck!
