I am looking to change my fertilizer program this year. I am in South Georgia with mainly centipede and st Augustine. I have been putting out 15-0-15 the past several years at 1/2 lb N 2 times per year. I am considering a change from that. The chlorine in this was 12% which I have recently learned is not good haha I am thinking one granular and then mixing a liquid that contains humid acid, seaweed, etc each time I spray a herbicide which would be 3 times per year. Thoughts?
