Tomatoville® Gardening Forums - View Single Post - Damping off: Pretreating germination mix with hydrogen peroxide

ScottinAtlanta · January 21, 2021

Folks, I set up a tray using Black Gold germination mix for the first time, and my kale and collards were eaten up with damping off. I watered with an ounce of hydrogen peroxide in a quart of water, and that saved about half of the seedlings.

Before I try again, I wanted to ask if it would be useful to pre-treat the germination mix with the hydrogen peroxide mix BEFORE I plant the seeds to discourage damping off. What do you think?
