Q.Black flies
How can I get rid of black flies that are on my Astilbe and Daisy plants outside? I’ve tried Basil plants next to them, doesn’t work. Thank you

I would recommend trying neem oil. It is effective against both harmful insects and fungus, and it's very safe to use. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
