What do I do to transfer a potted helleborus into the ground? We raise goats. Is helleborus poisonous to them?
Yes, hellebore is toxic to goats per Cornell University (http://www.ansci.cornell.edu/plants/goatlist.html) and is also toxic to cats, dogs and horses per the ASPCA.
Hellebores do best in moist, but well-drained soil in a filtered sun or shady location. Dig a hole twice as wide and equal in depth to the root ball. Potted hellebores have a tendency to be root bound so it is vital when putting them into the ground that you remove the potting mix and loosen the roots.
