sevin, mix using instructions on container. on the bitten area to prevent any bugs gettin inside...keep children & pets away from this until dry.............do this after the sun passes over.........wear old long clothes, goggles, gloves and mask..................next day when this dries use Spectracide pruning seal to protect the bitten area.........makes sure that you shake the can every time you spray, if it clogs up use a fine pin to keep it open. Use some chicken wire and make a cage around the bottom so that the rabbit can't chew it again. Put some rocks or wooden stakes to keep it in place. They have those plastic green stakes that you use to hold a tent down at the store. Rabbits also do not like dried blood meal....it stinks really bad, so use gloves use goggles & mask and sprinkle some around the bush bottom.. In the late fall.....sprinkle some very old horse or cow manure and lime it. The lime sweetens the soil.
