I am growing a zucchini in a pot. Recently, the leaf edges have been browning then turning black. The rest of the leaves are heading in the same direction. What can I do? The leaves are very dry and have lost much color.

You need to water more often. Zucchini are water heavy plants, so you should water at least once a day when they are in a container and twice a day if temps are above 85 F.
