Q.Tomatoes
I have been planting seeds and they start to grow inside. They come up quick, but they get about 2 inches tall and then they die. I don’t know what I am doing wrong. Can you help?

Are the seedlings falling over because the base of the stem is weak and mushy? If so, this is called damping off, a problem caused by fungus that frequently strikes young, seemingly healthy seedlings. You can read more about it here:

Are your seedlings growing in the right conditions? It's possible they're using up all their energy just to germinate, then failing because there's not enough of something to sustain them. Indoor tomato seedlings need warm, moist soil and plenty of bright direct light. You can read more about their requirements here:
