The main challenge we have experienced from the end of July and into mid-August is that we entered a period without rain in some parts of our region and temperatures being too hot (above 90 F) for some days.

Potato leafhoppers are pests on a variety of crops (fruit, vegetable, ornamental) and they do not overwinter here, so they migrate in from the south as the weather warms up.
