Last week I planted seeds in peat pots in my peat pot greenhouse. They are now up about an inch or two and starting to have dry stems. I have the heat on them for a few hours daily to give them warmth plus watering them. The corn and peas look lots better. Did I not plant the seeds deep enough? They are also starting to fall over.

If your seedlings are not getting enough light they can get leggy and fall over because the stems are weak. If you have supplemental lighting, keep the lights on for 14-16 hours per day. If you don't have supplemental lighting you can provide it rather inexpensively by hanging fluorescent shop lights over the tops of the seedlings, keeping the lights only about 2 inches from the tops of the plants and moving the lights up as the seedlings grow. Another common problem for seedlings is a fungal disease called damping off. This can happen when the soil is kept too wet and the air circulation is poor. You should either remove the lid or prop it up a bit so fresh air gets in and moves around your seedlings. Hope this information helps!
