I feed Miracle grow, I don't know about 10-10-10, but I do know DO NOT USE Bloom Booster, it is bad and will kill them. I used it and the leaves stared turning yellow. Boy! Did I stop fast??
Fall is coming.
I plant mine in the ground IN their pots. I have to pullthem up in fall to put in Greenhouse so they won't freeze.
