Will white fuzz on soil harm seeds?

Question

I planted pepper seeds in plastic cups a week ago and I’ve noticed this fuzz that looks like spider webs start to form on the soil. Will it harm the seeds, and how do I get rid of it? I’m using jiffy seed start mix with some jobe’s organic mixed in.

Answer 1

Yes, it can harm your seeds and eventually kill them. Start by decreasing the humidity around the seeds by removing the cover or poking holes if there is a bag around them. That should prevent the fungus from growing futher.
