Aphids- infesting many plants & none some. Coments? advice?
I an a new gardener, zone 8, dallas TX. The aphids have utterly infested my Zucchini, all other squashes and cucumbers. However some plants right next to these infested plants have none at all. Peppers, eggplants, yard long beans have none. Tomatoes have moderate and Okra have mild. I have sprayed the plants several times already.
Any thoughts? Are there any varieties of Zucchini, cucs, squashes are resistant to them, so i can grow those next year. Thanks.
