Does rough horsetail spread?

Yes, strongly, and it is very hard to remove once established in open ground. Always grow it in a solid pot or aquatic basket to contain the roots.

Where to plant rough horsetail

  • In a basket on a pond shelf, up to 10 cm deep
  • Large pots and container ponds
  • Contemporary and Japanese-style water gardens

Is rough horsetail poisonous?

It is not edible, and dried stems mixed into hay can harm livestock. Keep it away from grazing land and stop pets chewing it.
