I have a patch of gladiolus with great foliage but I don't get any blossoms. Do they just need fertilizer or is there another problem? They are in the sun and are well drained. Thanks for any help you can give me.

It may be lacking phosphorus. I would give the plants some phosphorus, like bone meal. If the foliage looks healthy but there are no blooms, phosphorus is normally the problem. This article should also help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
