Powdery mildew

Anonymous added on June 17, 2015 | Answered

I read in one of your articles about a diluted solution of hydrogen peroxide and water as an organic solution to powdery mildew on peonies. However, it did not give the ratio and I searched your site. I would appreciate your help and suggestions. Also, could not find a recipe for compost tea either to fertilize them. Thanks.

The treatment ration for powdery mildew is normally 9 parts water to 1 part hydrogen peroxide. We have added this ratio to the article to help with any future concerns, so thank you for bringing this to our attention.

As for compost tea, this article should help: https://www.gardeningknowhow.com/edible/vegetables/cover-crops/compost-tea.htm
