When to remove liatris corms and how to store them

9 years ago

Even though I live in zone 8a, it is not correct. I live in the high desert which is more accurately defined by Sunset Western Gardens as zone 11, or as I call it, "the kiss of death." Liatris does not come back the next year if left in the ground, I was wondering when to remove them from the ground to save them for next year and how to store them.

Probably once they go dormant, would make sense to me.

LOL!! You managed to hit one of the very few of the 24 or so Sunset zones where liatris is NOT reliable overwinter.

Here's what to do : In areas outside their normal hardiness, lifting may be needed. Simply dig and divide the corms in fall, drying and storing them in slightly moist sphagnum peat moss over winter. The corms will require about 10 weeks of cold storage before replanting in spring.
