Hi guys,

I started an organic garden last year to attract and help bees, butterflies and pollinators. Everything was going great until it was taken over by mildew!

I tried milk spray and made sure the circulation was good but it didn't work.

This year I want to be ready for it! I heard potassium bicarbonate (haven't a clue where to find it!) is meant to be good, so is baking soda and neem oil. Has anyone used any of these? Any other ideas?
It's not easy to find a bee friendly solution!

Thanks Smile

Try Baking Soda (Sodium Bicarbonate) mixed one teaspoon per quart lt of water, Fat Free Milk and water mixed 50/50, unfortunately you can't cure powdery mildew
Lack of good air circulation can exacerbate the condition. Powdery mildew usually arises when temperatures are warm, soils are dry and humidity typically high not a lot one can do about temps or humidity but making sure the soil is adequately moist and improving circulation can go a long way to slowing the disease. good luck.
