Growing equisetum in the winter

Mary Braid
by Mary Braid
I would like to grow equisetum hyemale (horsetail) in Maryland but I'm not sure how to care for it in the winter. Should I trim it back & since it will be in a pail of water will the roots survive being frozen?

    it would probably like being in the ground better than in the bucket. If you really want it in the pail, wrap the bucket as a fragile bush, cover the bucket with straw, with the equisetum poking through. (a layer of thermal protection) better yet, dig a hole and bury the bucket to the rim and then cover with straw. do not trim it back, the canes will still feed the plant during the winter.

      Thank You Ann Riffe. I was walking along the C&O canal here in Md today & I found a very hardy stand of horsetail growing. I think I will put it outside & mulch as per your suggestion. If I lose what I have, I now know were to get a start next year.....

    We trim all aquatic plants back to about 2 inches above water level and have never had any issues with them surviving the winter in any of our ponds

    Maryland is hardiness zone 5b to 8b and Horsetail is a 4a hardiness zone plant according to my research. I agree w/Ann that I believe it would do better to leave it in the ground and mulch it heavily. I push the zones and I live in 7 in Tenn. My Canna Lilies always remain in the ground hear but I heavily mulch them. Usually any damage that occurs is from an early hard freeze. Good luck!
