Yesterday I noticed a few white fungus spots on my indoor mint plants, probably some powdery mildew.
So I thought I’d give em a good spray with a mix of water, baking soda and a few drops vegetable oil.
Big mistake – they didn’t take it very good at all. This morning the mint leaves were all burned and turned black.
This is what the poor plant looks like, after I removed most of the bigger damaged leaves:
lesson learned: don’t spray mint plants with baking soda and oil. Or use a very mild solution, test on one or two leaves first and wait until next day.
