Any advice will help.
IMHO, you shouldn't plant inside rock to begin with. It negates physical soil management and heat gain by the rocks is not good. Also I hope your not dealing with an acidic soil.
Push comes to shove, I would consider MPRotators if I could irrigate over the plantings, not through them.
