Hi, My soil is only two weeks old and it is starting to get white mold on it. I am worried that my mimosa seedlings will die. The soil is perlite and peat moss with this weird soil from one of my junipers that I made in to a bonsai, I thought that it would be good and it is. I washed the peat moss vary well before I used it so i don't no why it has mold. My plumeria seedlings have this weird yellow fungus, the soil is a mix of perlite and peat moss. I don't know what I'm doing wrong please help! thanks.
