At what rate should lime be applied to bermudagrass?
It all depends on your soils ph. I applied lime to my yard this fall at the rate of 100 lbs of pelletized lime to 5000 sq ft. without having a soil test and it did not hurt my grass.
Contray to popular belief, ph has nothing to do with how much lime you need. You can have a very high Ph and still need to add lime. Lime, calcium, will raise the ph of your soil,, but in cases of soil with exceptionaly high ph's, Lime can actually lower your Ph. Whether or not you need lime should be based on the Cation Exchange Capacity and base saturation of calcium in your soil, not Ph. If your soil just needs calcium you would use calcitic lime, if your soil also needs magnesium, you would use dolmitic lime, if your soil needs calcium and sulfur, you would use gypsum. How do you find out how much lime, and which kind, you need, spend the $10 bucks and get a soil test. It's cheaper than adding something you dont need
