Is this a good time to split a huge hosta and replant it in a different location?
I have several varieties of hostas growing into each other. Can I divide them?
It is getting a little late, and you may have some fail to make it, but generally you can divide them at anytime that they are actively growing. This article will help: https://www.gardeningknowhow.com/ornamental/foliage/hosta/dividing-hosta-plants.htm
