Dividing Hostas

I had this beautiful mass of hostas that needed to be divided. Not only did the plants need to have more root space, their unique and beautiful color would make for good accent plants in my container garden. I wanted to divide them, but I was wary of how difficult the job would be.

They were so close together that none of the advice offered by youtube gardeners would work. An example was one video that said to shovel at any spot in the hosta mass and be "brutal." Just dig 'em up and tear them apart. I couldn't even get a shovel to penetrate this mass of hostas.

I decided to saw the roots. I saw an inexpensive saw at Aldi for $6.45. Mother Nature cooperated by soaking the hostas





I found cutting the roots to be surprisingly easy. The lower shot shows a closeup of the cut roots.

I transplanted them into window boxes and other containers. They are still undergoing a bit of a shock from having their roots cut, but they look surprisingly good.

You're much nicer than me. I just go after them with a shovel.

Been transplanting tons of things lately from my big flower garden, to other planting beds. They're all surviving.

And the mass is really heavy. All mine really needed to be thinned. Last year they pretty much took over. So I did it right when the tops of them appeared. I had to move so many once I thinned them. I actually had to start new beds.

I have an d bowie knife I use outside for cutting tubers apart and cutting turf.
