There are two types of gardeners in the world:
clumpers and splitters. I admit it-I am a clumper. I cringe at the idea of cutting my babies up into pieces. I would rather leave them alone so they can get big. Wait, not big-huge. I want huge Hostas. Digging them up and dividing them can set them back and, to be honest, I do not like doing that because it takes some varieties forever to reach a good size. A solution I came up with is minimally invasive, and it does not set my Hosta back like digging up the entire clump does.
