What is the best fertilizer to use to help aid in transition of bermudagrass?
You have a few options, including spoon feeding your lawn every 2-3 weeks with low rates of nitrogen to encourage growth–or you can apply a heavier rate of ammonium sulfate to really push the growth. A heavy rate is 5 pounds per 1000 SF and doubling or tripling the rate does not speed up the process any. You can spoon feed the ammonium sulfate every two weeks at .25 pounds of nitrogen which is 1.25 pounds of product per 1000 SF until the warm season grass pushes its way through the ryegrass. Recent studies have shown that granular managanese sulfate and zinc sulfate applied at 2-3 pounds of product each per 1000 SF will help the warm season grass in transition by sending available nutrients down to the roots for a healthier plant. Please note that these must be “granular” products. You can often find these at a nursery in the section with palm tree fertilizers.
