I have read many post about overseeding Bremuda and see mixed feelings. I have a sodded bremuda yard that is VERY thin which is from lack of water and 3 years of not properly maintaining (fert, mowing regular and watering). I sent off for a soil test and was surprised the results were not bad. The pH was on mid to high end. I was curious if anyone has ever done hydroseeding as a form of overseeding. I just finished installing an irrigation system and plan to overseed in one way or the other. I want to get some new grass coming in over the entire lawn opposed to just filling in the thin areas. I plan to cut the grass real low, aerorate, spread thin layer of top soil/compost and then over seed. Lastnight I came across some information and videos of people hydroseeding their new lawn and even overseeding using this method as well. To me it seems they have much higher success rate than just overseeding with a spreader so I am considering this as an alternative. I understand the cost will be a little more but would it be worth the cost to do it this way. The local sunbelt rents the machine for $250/day. What are your opinions on hydroseeding in my situation. Yard size is about 8500 sqft. What is a good bermuda seed to use considering my sod is probably some form of hybrid bermuda. I live in upstate SC. Lawn is in full sun. Thanks for your help.
