Year after year I’m having issues with damping off when sowing things like thyme, oregano and marjoram indoors. They wilt as soon as cotyledons emerge. Sometimes I can save a couple of sprouts by sprinkling cinnamon powder on top of the soil. Do you have any other ideas I could try on my sprouts to give them a better chance?
Here are a couple of things that I do to minimize damping off.
- I generally keep a small house fan running in the room where my seedlings are. This keeps the air moving and helps dry out the surface of the soil, which helps a bit.
- I use a product called “Serenade garden Disease Control” which is a biological anti-fungal that I spray the surface with, which reduces the surface mold and gets the plants through.
Not sure if these tips will help, or if the spray is available where you are, but they might be worth a shot.
