See details for question.
I have a large outdoor pot with morning glories. Recently the leaves started to wilt and die. While cleaning up some dead leaves, I saw that the dead leaves were infested with aphids, probably in the soil also. Will these aphids die over the winter or will they re-emerge when the weather warms in the spring? Do I have to dispose of all the potted soil and start over?
