I've dug up and cut off the tops of my glads yesterday. Most of them still had green tops. Will they flower next year? I didn't realize I needed to let the top die back before I dug them up.

The foliage, or what is left of it, should still die back on its own during storage. This should not affect next season's blooms, but just in case, add some bone meal to the soil at planting time to help encourage flowering.
