Does anyone use anything to prevent mold growth on seeds?
I read a random thing about soaking seeds in Hydrogen peroxide for 4 hours before germinating, and tried it with some of my seeds this year. Paper towel method. I still got mold growth on some (certain varieties more than others.) Germination rates were low, except for the singles and collarettes, but there are plenty of reasons that might be, considering this is my first year collecting & growing my own seed from fully double forms.
I recently found a weak solution of elemental sulfur in water in a spray bottle has been effective against powdery mildew, and have contemplated testing that with some seeds.
Anyone have any experience they’d like to share? Do you just figure some of them molding is par for the course, and just remove the seeds that mold?
