    Most plants require temps to remain at least a consistent 55-60 degrees F. before planting them outdoors. This does not include hardier crops, like lettuce or most root crops, however. Since you're experiencing temps in the 40s, I would give it more time before putting them outside. When it warms up enough and they're ready to go outdoors, I would recommend hardening them off first.

    I would bet it is from too much water. Only water when necessary. Put your finger into the soil and see if it feels damp to the touch. If it does wait a few hours or a day depending on temperature and check again. Too much watering will also leach the nutrients out of the soil. A liquid fertilizer added to the water once a week should solve your concern.

    It sounds like they had enough light and heat, so water would be the likely culprit. Potting and seed starting soil is normally high in peat. Peat can dry out and actually start to repel water when you water, so while you think you are adding water, only the top part may be getting wet. The lower part stays dry and the roots just don't develop right.

    You can prevent this by making sure that you keep your seedling soil damp at all times and don't let it dry out completely. If you do accidentally let this happen, soaking the tray in a tub of water for a bit will force the peat to rehydrate and start taking water again.

    You can plant them the recommended length apart. They will be fine. I had an entire garden doing that. There are still times when you must thin anyway, if they are on the same mound, and one or two of them are dying it's better to thin the dying ones so that they aren't taking moisture from the one(s) that is living. If they aren't on the same mound you have nothing to worry about. Hope this helps!

    You need to keep seedlings on the ''slightly dry side of evenly moist''. Too wet will cause a multitude of problems. There is a vast difference between wet, moist, damp and dry. How much or how often to water depends to many variables, air temperature day and night, humidity, light, soil, size container, air movement, size of plant...and so on.

    Thanks, I have my seedlings in half drums in full sunlight. we water them lightly twice a day, and fertilise them with liquid fertiliser every 8 to 10 days. Our normal summer temperature is about 28' C and we are quite sheltered regarding wind. Because we are on a hill we experience no frost in our winter months.

    This question is not easily nor quickly answered. Depending on the plant(s) in question, several variables (such as moisture, nutrition, light, temperature, media, humidity, air movement, container size and type, and variety) would need to be identified.
