Has anyone here any experience with overseeding Bermuda with Bermuda? For example maybe you have some unknown variety that has gotten a little thin due to things like soil/shade...whatever. And let's say some improvements have been made to fix those things. Can seeding help dense up the current lawn or should someone just start the year continuing to cut low/cut often/fertilize/PGR...etc and let nature do it's thing?
I did this project this year and do not recommend it. Reason being, you will end up overseeding a different type of bermuda into your lawn, and while first glance you might not notice a difference, a more closer look will show slightly different shades of green, etc.
Because I chose to overseed this year, I did not lay a pre-em, and ended up fighting weeds for most of the year. If I had to do it over again, I'd lay the pre-em, skip the overseeding, mow low and add fert to encourage growth. If you can't get the grass to spread while maintaining low and fertilizing, the grass isn't meant to be in that area in the first place. Could be shade, compacted soil, moss, etc.
I felt afterwards that I had wasted the $ on the bermuda seed.
