Are these full-sun species?

[BarryRice]

Hey Guys,

I grow most of my plants under 30% shade. However, I grow the big-to-monster plants, like Echinocactus grusonii, Ferocactus latispinus, Echinopsis terscheckii, E. chiloensis, E. pachanoi, and E. peruvianus in full sun in my central California back yard.

A couple of plants, which have been in shade, are starting to outgrow my area. I'd like to move them to a full sun location. I know that I'd have to do it gradually, but can these guys grow in full sun?

Ferocactus pilosus (=Ferocactus stainesii)
Ferocactus hamatacanthus (=Hamatocactus hamatacanthus davisii)
Ferocactus texensis
Ferocactus macrodiscus

Cheers

Barry

I grow all in full sun except Ferocactus macrodiscus. That one I don't have. You may want to wait until the summer is over since they are not use to the full sun. You may find all little sun burn, the Valley sun is tough. And for the "Big Monsters," most of those I have and all grow in full sun. Some get a little burnt and a little damage, but that is expected being in full sun.

I grow macrodiscus in full sun,I think every fero and echinocactus can take full sun.

Do you think the white-spined variant of Echinocactus grusonii is sun-hardy, too?

Cheers
