Fixing to fertilize bermuda for the first time and looking a ordering enough fertilizer to cover my next 3 rounds of fertilizer on bermuda. Can't decide what to go with. Got 2 choices and are at different suppliers. What do you like? 28-2-3 25% slow release 30-6-10 50% slow release XRT with micros.(will cost me $0.17 per 1000 more than the above 28-2-3) I'm usually fertilize every 6-8 weeks and will go with .75-1 lb N on the first round and .75 lb N on the next 2 rounds.
