am trying to grow tomato seeds , the initial stage was successful and my seeds are germinated , i have separated seeds and placed them in cold drinks disposable glasses , i water them and have placed them in my room window , but they are not growing they are dying with germinated two leaves , i do not know why they are not growing and keep dying ? Is it because i have not placed them directly in sun light or what ? here in our city temperature is high its about 40 Celsius , enough temperature to burn these new born plants. So any suggestion or anything am doing wrong ?
It's hard to say for sure, but here are a few observations:
- That soil looks somewhat unfit for seedling production. Start with a commercial garden soil or preferably a product labeled "seed starting mix".
- Do those drinking glasses have adequate drainage? You need to water seeds and seedlings frequently, but the soil has to be loose enough for those tiny roots, and the soil needs to remain well drained.
- 40° C (104° F) is typically too hot for tomato plants. Garden Know How suggests a constant temperature between 14-16° C (58-60° F). Depending on the variety, you may want to wait for more temperate days and cooler nights. If that is not an option, they will need the brightest, indirect (or filtered) light you can muster — maybe tolerating some direct sunlight in the early morning and evening — but keep them out of that hot midday sun until they become better established.
Must agree, that soil looks like it's a tight binding, water holding, silt? Tomatoes (and most other plants) would hate that at any stage. It also looks as though they're baking. . . Try some better soil, or amend what you have with a bunch of broken down natural-matter, leaves, etc.. Then, until you get some plants up to 4-6 inches, I'd pull them back from the window, perhaps use a light instead until they can start dealing properly with photosynthesis on their own. Once they hit 4-6 inches, they need a bigger pot, better soil, water, fertilizer and, if it's really over a hundred degrees F there, you might need to monitor and control their exposure times. That's pretty hot for a non-matured tomato plant. Once you get several large plants growing, they can and will protect themselves and create their own mini-environment to deal with excessive heat. (We grow 50 plus plants and when they're full size, sitting in the midst of them is the coolest place on our farm to sit when it's 100-110 degrees.)
