How to Prune wax plant?
Unlike many plants, there is no need to prune your porcelainflower at all. New foliage will grow from the ends of the plant's tendrils, leading to new flowers developing if the conditions are ideal. The porcelainflower does not respond well to severe pruning, but you can lightly trim it to control its size, or to cut away any dead growth. Do this in early spring, just as your plant enters into the growing season. Any pruning outside of early spring is highly discouraged.
