I can scrape them, and the plant can heal by itself.
If not scrape, it's sometimes turn black and rot.
Any one know what disease?

Help,Echinocereus seeds's vitality?
Any one has experience with fresh Echinocereus seeds?
I just collect some Echinocereus scopulorum seeds.
Should I sow them now?
Or need to preserve them for severl months?
Or generally fresh seeds won’t germinate very well; only old seeds do?
