gladiolus corms

Question

It is almost winter and the corms are sprouting. Should I dig up the corms at this time to store for winter? There are so many corms that there are very few flowers.

Answer 1

Yes, as long as the ground is still workable where you are, I would go ahead and dig them up to store over winter. This article will help with storing them: https://www.gardeningknowhow.com/ornamental/bulbs/bgen/how-to-store-bulbs-that-have-sprouted.htm

It should also help with the overcrowding. Simply divide them up and replant elsewhere next season. This should help with blooming. You may want to add a bit of phosphorus to the soil as well.
