Granular is not a time release so it will leach the phoshorus out now, and phyto does not form until probbly at least march in your area, so yep think it is a waste of money and time.

Just plan to start the water soulble a month or so b/f shad stocking. You might have to fertilize as often as every ten days to get the bloom started but once established easier to maintain. good luck.
