I've only had a handful of zucchini so far this year. I'm wondering if the row cover is worth it. I just can't keep the flowers pollinated well and the plants don't grow as well underneath the cover (unlike other plants that seem to thrive under a cover). It won't be long before powdery mildew takes over the plants and they all die off. So do I get a better harvest this way? Or just a later one? Probably the latter. And the cover is a lot of work. I think next year I won't bother.
