OK, here's a tip for those of you with mysterious lawn problems.
I consider myself a pretty decent yardsman, but have been stumped by my weak front yard that I inherited.
Brief history/details:
Previous owners had sodded (!) front and back yard with Empire zoysia, which loves our hot and humid weather. Also installed an irrigation system to water said sod.
Apparently after moving out, they didn't water, and the front yard died out...so they (I assume) overseeded with centpede, which I am generally not a fan of for multiple reasons (lazy man's grass my butt!).
Anyhoo, fast fwd three years. I fixed all irrigation issues, repositioning some heads, replacing others...but the front still looks TERRIBLE, even with my Milorganite treatments, pre-emergent 2x year (the good stuff too, not the cheap-o, which DOES make a difference), hand weeding, the works. Even brought some Empire Zoysia sod from my old house and put it out in a few places.
Yard looks terrible, full of weeds, seems to look tired and beat even after watering.
After all this time...the answer it took me forever to come up with is THATCH. @#%$@%#$
Relatively easy problem to fix, but I have put a LOT of water on that grass trying to get it to perk up. But thatch prevents not only water from getting to the grass roots, but everything else too - including pre-emergent (thus the weeds), fertilizer, iron, etc. NOTHING gets through this very thick barrier.
Some things I learned - maybe will help someone else:
1. if you have more than say 1/4 acre to de-thatch, do NOT try buying a de-thatching rake...you will kill yourself. Either rent a power dethatcher, or buy a $115 corded version (Greenworks)
2. Not all grass types need dethatching, but if your grass types spreads vigorously (centipede, zoysia, bermuda, et al) you will likely get thatch buildup after a while
3. Grass clippings (if you don't bag, which I don't) are not the cause of thatch
4. If you have a grass type that builds up thatch, you should only need to de-thatch every 4-5 years
I should take a before and after of my front to see how much of an improvement this will make, but I have high expectations!
Thought I would throw this out there for anyone who can't seem to get their grass looking good, or feels like they are working too hard for too little results - might be time to de-thatch.
