Growing plants from cuttings or by buying the plant itself at places like home depot are so much easier in my opinion than growing plants from seeds. Every single time I tried to grow plants from seeds, they either died off from dehydration or they would die off by too much water. But by taking a few minutes to make self-watering pots from water bottles, seeds are so much more easier to grow. Covering them up is not necessary to do if you have self-watering pots. Here are some pictures of cotyledons of the plants I am growing : )
After a few more days of waiting, I am thinking about separating the peach celosia cotyledons so that they will be less crowded. I think I heard from somewhere that they do not like their roots being disturbed, but it is ok to move them around when they are cotyledons. Of course, moving them around a lot is never good, but once should be ok, I hope. More seeds will come to me through snail mail and hopefully, those will grow successfully too.
Vegetables will be grown outside in my earthbox : )
