Planting under rose trees
"I live in Southern Calif. I have 3 rose trees that are doing wonderful ( 3 years old). They are in big brick planters out front. Is it okay to plant Red Apple Iceplant in the bottom of the planters? The rose trees bloom constantly and I didn't want to smother their roots. My other question is, if it is okay, what kind of food should I use that would not bother the iceplant.
Thank you very much"
