This is a yard that I'm taking over in Greenville, NC. What I'm about to explain is a very common situation. I have four types of grasses in this lawn (centipede Bermuda crab grass and zoyzia). The centipede is sparsely distributed throughout the yard. Sod is out of the question for the customer. The customer is not interested in spending that much money. We have agreed to establish Bermuda and the yard. And we plan to do this with seeds. So here is my approach. I have already applied pre-emergence to the entire yard. I did this to suppress crabgrass growth. In June I will cut the grass down low, and aerate and spread Sahara Bermuda grass seed and treat with XLR8. I could consider to round up the whole from yard and start from scratch too. But the Bermuda that is already established is pretty good.By July we should have a fairly established germination and yard. What Do you think about my approach? What would you do in this situation?
