could opuntia cactuses grow outdoors in Oregon?
I have a little over 50 cactus plants I grew from some seeds I got off of E-Bay last winter which were labeled Opuntia Gigantea Robusta. The man I got them from said they grow wild where he lives in North Carolina. He also said that since he lives in a zone 7 they should grow fine here in St Helens OR since it is a zone 8. My only concern is that it rains A LOT out here in the spring, autumn, and especially winter so I am afraid to plant them outside because I donÂt want them to rot. Can this type of cactus handle months of wet weather? If not if I were to plant them in gravel would that keep them from rotting?
