Q.Planting Hardy Succulents In Ground
I live in Georgia zone 8b. I would like to plant sempervivums and sedums in ground, but not sure how to prepare the area and with exactly what substate. I figured a succulent/cactus mix amended with pumice and chicken grit would be fine. Is there something better I can use that won’t be as expensive and won’t kill the succulents in the red clay ground where I want to plant? I’ve read to use regular potting soil and mini slate chips. Please help with what would be best in my area!
