For anyone that can help: My yard was sodded last spring (April 2019) and seems to have a terrible time breaking down thatch. I typically mulch my grass with a mulching blade on the push mower, but when you spread apart the grass there is definitely a build up (1" or so) of really fine old grass clippings sort of matted to the ground.
A neighbor of mine told me spreading pelletized lime can help with the thatch breakdown. My rudimentary google search/investigation revealed that too much lime can burn your grass, and the application should be based on the ph of your lawn soil.
My question: is lime a good option, and if so what is the best way about finding the ph of my soil? Amazon test kit?
