How to use traps or companions?
Last year I had white flies on tomatoes, bad. This year the flies are back as expected, but seem to favor my snap peas as of now.
I was going to pull the peas, but wonder if I should leave them as a trap? And should I be treating the peas to eleminate as many flies as possible, or will they move to toms as soon as I treat peas? Too hot for peas soon, would another trap help?
Any experience shared would be appreciated.
