Click on links below to jump to that question.
I planted tomatoes around Valentine’s Day and now they look a little yellowish. They are about 2 1/2-3 inches high in 3-inch pots. I’ve used seed starter potting and planting mix. Plus I have a heat lamp on them with temps between 70-80 degrees, and they are in the sunshine when available. I water them every two days, sometimes I water the bottom of the pots, or from the top. I haven’t fertilized them yet, but I still don’t like the yellow look.
My greenhouses are infested with symphylans, and last year I lost 600 tomato plants because of them. What kind of organic formulas or pesticides can I use on them this year? I have decided to keep the tomatoes in big pots, but I know they can travel up into them. I am going to use wood ash below the pots, but I feel I need something more to combat them. Can you help me? They came into my garden in either some organic soil that I bought or some peat moss.

I would also recommend trying neem oil on them. It is organic and effective. Here is more information:
I have heard that Diatomaceous earth will help to get rid of them. I have also read articles about placing pastic over the entire garden area on a sunny day, before any plantings of course, and leaving it there all day long. This is said to heat the soils up and due to them being delicate bodied creatures, the heat kills them.
I recently planted a tomato plant in a peat moss container. However, I am going away for a few days and have no one to water it. How do I keep it wet without disintegrating the peat moss?
I want to grow some vegetables on my deck; however, it does not get a lot of sun, and that’s only in the morning. I know that I can grow many in part shade, but if I wanted to do tomatoes, how much sun do they need each day, and could I use a plant light to supplement for the lack of direct sun?
This article will help you with light requirements:
You can use a fluorescent light. I have also seen people use mirrors too, to focus available light on the plant.
I have grown tomatoes and eggplants from seed under artificial light. I attempted to harden them off once before when they were 4 inches high. They became sunburned. Now after two more weeks in the shade outside at 70 degrees (average temps in the day) and around 45 at night, I am scared to put them out in the sun again. Can you provide any tips to make my second try more safe for my plants?
Move them slowly into the sun. They need to build up a tolerance. The first day, just do a half hour in the sun or so and work them up from there. This article will help too:
Strangely, we have planted many vegetable seeds (like always) indoors and they sprout and are looking good at 2-3 inches tall (spindly). Then they all seem to die. It doesn’t seem too wet or dry. Our tomatoes, cauliflower, and broccoli all died quickly. What happened?
Sounds like you may have a problem with damping off. Here is an article that you may find helpful: https://www.gardeningknowhow.com/garden-how-to/seeds/what-is-damping-off.htm
