Pardon me if I'm not posting in the correct way but I'd like some answers to gardenias.
I have 10 gardenias. Mostly August Beauty, Daisy and Radicans.
I question is I live in N.E. MS (zone 7) and have horrid red clay. With the others I planted I didn't really do much except dig a large hole ad shallowly planted them. All are thriving but I read somewhere recently a recipe for backfilling using sharp sand and a couple other additives.
Might anyone offer any advice on the best backfill and mulch to use?
Thank you,
Lee
