If you missed it, let me recap a few items. Mike says, 1. Don't use oils and soaps in direct sunlight. Use early morning or at night. It only takes an hour or so for the soaps mixes to kill the pests so wash the solution off after an hour.
Plain water is one of the best pesticides especially with aphids.
A sharp spray will kill most pests. Soaps and oils can harm some plants. Test plants first. All rights reserved. Used under License.
