Black Fly.?
Question:How do i treat & prevent black fly on my tomatoe plants & hanging baskets???
Answers:
Plant some marigolds/tagetes amongst your tomato plants
Slugs love them though.
You can spray them with a very light solution of washing up liquid and water. It wont prevent them but it will kill the flys already there. Just be careful not to over do it.
Use Safer Soap, it what the greenhouses use...it come sin a liquid squirt bottle for about $4-5
put marigolds round base if tomatoes in a greenhouse throw a frog in will eat all blackfly and greenfly spray baskets with derris powder
