When to start using an insecticide?

I have been using Spray N Grow on my tomato plants and my herbs since transplanting them in containers about 2 weeks ago. I am using the Spray N Grow along with Mr. Bill's Fertilizer on all of them about every 3 or 4 days. I was wondering if this alone will protect my plants from INSECTS? Should I wait until I see any insects or should I spray with insecticide to ward off any insects that may be in the area now? Also if I do have to use the insecticide how does that work with using the Spray N Grow and Mr. Bill's Fertilizer? Any help with be appreciated. Thanks, Eileen Hayes

I don't think by using Spray -N - Grow alone that it will not ward off insects. Using spray-n-grow every 3 or 4 days I believe that should be sufficent enough, then wait and use the insecticide then use spray-n-grow again. On my roses I use spray-n-grow once every a week then the insecticide.

Hi! Yeah, you will need to use an insecticide along with the Perfect Blend Kit (which is only fertilizer and vitamin supplement). I'd follow Bill's advice and apply SnG, then insecticide in a couple of days; you'll also want to re-apply the bug stuff after a rainstorm, and you can mix the CocoWet with it to make sure it sticks good.

Good luck to you!
