Its been a wet winter here in southern california and the pests are out of control! I have a couple large rose bishes near my garden and its a haven for all the bugs. Ive tried spraying heavy with seven insecticide and they just seem to laugh at it. I would pull the rose bushes out if i could bit i rent my house and im not allowed to. I have a feeling the majority of my bugs (mainly aphids) are coming from the rose bushes but i have no idea what other products are good. Im thinking of using a systemic insecticide on the roses but i know i cant use them on edible plants. Does anyone have a suggestion for heavy infestations? Ive used neem in the past with fair results at best but im afraid it wont put a dent in the heavy infestation im experiencing. Thank you in advance.
