I have some hosta plants that are getting quite large and are crowded where they are located right now. What do I need to worry about when moving/splitting hostas?

Don't know if this is the best technique but here is what I did and it worked :)

Go all around the clump pushing in a shovel as far as it will go. You should now be able to pry/lift the plant out of the hole with the root/dirt ball intact. Work the shovel down between the plant stems to slice/pry them apart trying to keep as many of the roots attached to their stems as possible. I divided the root ball into quarters leaving a generous clump (5-10) of stems with lots of roots still attached for planting.

  • This method worked for me as well. The best time to move hostas is late summer/early fall or spring. – Shanna Jun 16 '11 at 9:24

    They're pretty tough - I ended up using an axe to split one of mine, and judging from the results it thrives on abuse. – chris Jun 16 '11 at 17:20

    I use an old hand saw to split plants. Sure, it cuts some roots, but it's pretty non-damaging to everything but the actual cut portion. – pboin Jun 21 '11 at 15:52
  • When using relatively decent soil conditions (ie. not sand) I have yet to succeed in "killing" a hosta by splitting, moving, or replanting one. I have literally handled thousands over the 8+ years as a landscaper. Sure, leaves may die or wilt in the initial season, but EVERY year they continue to pop back up. Have at it and split away with a spade, axe, shovel, your hands, trowel, edger... – Phlume Nov 22 '14 at 15:42
