Thinking about the radishes. It’s so hot now, not sure they will do anything. My garlic/pepper spray recipe has some dishwashing liquid added to it along with onions.
I hate to use it, because it doesn’t distinguish between the good and bad bugs, but it does kill whatever you squirt it on. Not sure how long that lasts. Hope to do it in the PM and hoping that by the AM, it will be less potent.
I had flea beetles the past two years. Not sure if it was Sevin, or Spinosad , or just not planting what they like to eat..brassicas. They haven’t been a problem this year.
