Hi
I start my seedlings on a bench outside and I am having trouble with some of the potting mixes that have replaced peat moss with compost up to 60% in the mix. They are also using less or no perlite.
The seedling initially grow , but then turn yellow and die. The media is heavy and wet.
I think the mix is heavier because the compost does not dry as fast as peat moss and there isn't enough perlite for drainage.
I water my seedlings and potted plants every day. Is that too much with a compost based potting mix?
