Q.Will powdery mildew come back in same place every year

At the end of the season last year both our broccoli and zucchini leaves had powdery mildew on their leaves. Getting ready to plant veggies in same raised beds. Should we do anything to prevent powdery mildew again?

Yes, that powder is the spores of the mildew. Left untreated it will come back more and more each year.

Treating powdery mildew is one of the easiest of the fungal infections to cure, though.
