Lets remove the mystery behind hostas. Here is the easiest, fastest way to thin and separate overgrown hostas while propagating new plants to grow or share.
1. Start by digging around the plant edges, a few inches from the plant. Push the shovel all the way into the ground in a complete circle around the hostas. This is your root ball. It could be very heavy if you’ve let them overgrown for too long, so ask another person to help lift it out of the ground and onto the grass or in a large bucket.
3. Shake the roots. Don’t worry, they are pretty tough. Shake the roots, water some more to remove dirt, and tug at the rhizome clumps. Don’t force, just tug. Keep watering while you work, it goes faster.
4. If you identify a rhizome but can’t shake it loose, go ahead and pull hard but WHILE holding onto the rhizome. If the roots won’t come with it, go ahead and cut them. They’ll take longer to grow but they won’t die.
That’s it. You’ve separated your hostas. Now you need to decide whether to share the thinnings or keep them for yourself. 🙂
Replant at the same depth you dig them up from. Water well.
