![]() ![]() If your tomato plants are just past the transplant stage, then they may be suffering from transplant shock. To learn more, check out this article from Grow Light Info on how close to put grow lights to plants. Make sure to put the tomato plants close enough to the grow light (their tops should be a few inches away, depending on how powerful the lights are).Īn LED is a good option for a grow light, since it doesn’t waste a lot of energy on heat production. If that isn’t possible (or if it doesn’t give enough sunlight), use grow lights instead (LED or fluorescent bulbs are good choices, while incandescent bulbs waste a lot of energy by producing a lot of heat). Put them in a window sill on a south-facing side of your house. To avoid tall and leggy tomato plants that may bend over or fall over, give them consistent light. You can learn more in my article on why your tomatoes growing so tall. Even if you put them under a grow light, they will grow leggy if the light is too far above them. If you keep your seedlings in an area where they don’t get enough sunlight, they will start to get leggy (tall, thin, and spindly). If the light source is far above the seedling, it will grow tall and thin to reach up and get closer to the light. Without enough sunlight, seedlings will get tall and may bend over. (If you are worried about not having enough plants, start a new tray or pot of seeds to make some more seedlings). ![]() This will help to prevent the spread of any disease between plants. Quarantine plants – if any seedling starts to look sick, pull it out to separate it from the other seedlings.You can learn more about the ideal conditions to germinate tomato seeds in my article here. Your best bet to avoid damping off is to keep the soil warm and moist to encourage fast germination. The faster tomato plants grow, the sooner they get strong enough to resist damping off. Cold or dry soil also delays seedling germination and slows the growth of seedlings. Keep soil warm and moist – damping off is more likely to happen in cold soil.Instead, buy clean and fresh potting mix to start your tomato seeds. Old soil may have soil-borne diseases from previous years. Use sterile soil – don’t reuse garden soil or potting mix.To prevent damping off, take the following steps: Any seedling that suffers from damping off (caused by fungus) will not look so good.ĭamping_off_(cropped).jpg How To Prevent Damping Off Of Tomato Seedlings
