I feed again after spring bloom, and the Re's get an extra dose ! Along with some extra water. As far as the pellets, in my opinion ,the nitrogen value is very small, and being organic in nature, is very "slow release". I would guess that the nitrogen is pretty well "tied up" in breaking down the pellet, so there wouldn't be very much actually added to the soil. same would be true with the corn gluten meal used as weed control . As to the borers, when my folks lived in Arkansas ( up by Lake Norfork) they had some borer problems (it seemed worse in the newer TBs) but not many. ...Arlyn
