Hosta 'Metallica' after being divided this fall
Fall is one of the times of the year when hostas can be divided. If you are going to divide hostas, it should be done in spring or in fall. During the summer hostas are busy growing their roots, and if you divide them they will not be happy. Who wants sad hosta? Not me! Can you tell sometimes that I teach in an elementary school? When dividing hosta in fall make sure to do it 4-6 weeks before hard frost.
How should you divide a hosta? Well if you want to be careful about it, and divide off certain eyes you can follow this link. Otherwise you can just place a shovel (I prefer a transplant shovel for the job) somewhere in the middle of the hosta and step down. You now have two hosta. Use a garden fork or a shovel to dig up the hosta you want to move. Depending on the size you can divide a hosta multiple times.
