Welcome, Hetty.
Gee, I don't know anything about growing cactus. I grow cactus successfully. Well, let's just be honest and I'll admit they seem to grow with no help from me.
Succulents are a touch and go thing with me. Some grow some die.
As you can see there are some people posting gorgeous pic of their cactus ... these folks know what they're doing! Maybe someone will speak up!
