I have an entire back yard and hillside of 419 tiff. Its tough stuff. Just water and it comes right back. Its grows slowly but it will come back. I keep mine mowed pretty short. You can't kill that stuff unless you use bonus S fertilizer/weed and feed. I sprinkled some of that in a spot where I had some weeds coming up. The weeds died and so did the 419 tiff. However, the tiff spread right back over and filled in again nicely. I don't think that 419 tiff tolerates any kind of weed and feed. I haven't found a weed and feed yet that it will tolerate. I usually just hoe any weeds out now. But that stuff grows so thick I seldom get any weeds in it anymore. I started with a few pieces of sod that was given to me. And it took over my entire back yard and the entire slope behind my house. It definitely spreads pretty quickly. And it seems to like this sandy clayish soil I have that holds moisture pretty well.

I'd keep mowing high. The green sprouts will be seen shortly if not already.

I went ahead cut it pretty low today, below 2 inches. I think my problem was that the stems grew higher than the highest cut on my mower while I was away and I basically shaved off the deep green blades on the prior cut. I understand what to avoid in the future and that I need to maintain a lower cut with Bermuda.

From what I'm reading, everything should get green again soon but it looks pretty brown now. I'll update soon. Thanks for the feedback!
