There’s a few large patches(60x40) of St Augustine that I was a little late watering during the recent drought and I’m afraid they bit the dust. Is it best to cut it out and resod the areas or wait for it to reestablish? I’m hoping to see some new growth soon but it’s not looking good.

In my opinion it will bounce back. I get a little concerned about weeds when it happens, but that is in my zoysia. My St Aug in the past would always bounce back as strong as ever.

Cut some plugs or runners from a good area and transplant to the bad area. Water the transplants on the reg

Just water and see what happens. Never good to make knee jerk reactions.

Spin-off question: if a specific area is prone to dry-out and isn’t under a tree, what should I do to this spot to keep it from being so prone to burning?

You can do a couple of things. You can add compost to the area, you can add Sodium cocoyl isethionate (baby shampoo but read the bottle to make sure that ingredient is in it), and you can buy a trickle hose and curl it up over the hot spot.

Are these spots where aerating would be particularly beneficial? Mine seem to be at the top of small slopes, maybe where grading activity scraped the ground the most during lot construction.

I think that is a great product but what I don’t like is that it lists the ingredients as nonionic surfactant. The ingredient in baby shampoo is also a nonionic surfactant. You are getting other good things with hydretain but I wish they were specific about the surfactant

This seems to be what’s happening in my yard and all along my street with St. Aug. Rainwater (if we’re so blessed) and sprinkler just runs off and doesn’t soak through on even minor slopes.

I formed this theory after I laid down some St. Aug in spots, in June…. and it’s mostly a lost cause even watering the hell out of it. But it’s Texas and it’s basically like living in the fricking sahara the last 2 years.

Spin off to your question: I have a metal shed in my yard and I think the radiating heat is killing the grass all along it and about 8 feet away from it. Did the same last year (first year I had the house) so I believe it will be an ongoing problem.

Any ideas?

I have the same issue man, I just water that area more deeply than the rest of the yard. I basically just let the hose run in that area for a minute or two. I forgot about it last week and it got crispy.

Be careful doing that though because if your lawn is stressed right now (like mine is right there), you can do some real damage over watering.

ETA: Just want to make sure you don’t overwater when it’s stressed like it is, you will kill it. I only put excess water when the lawn is healthy. Right now, run your sprinkler in the morning 2 mornings in a row (the sun/heat will evaporate some water in the afternoon) and see how it does.

I have one section in my yard about 25' square. I figured this was the area that the equipment used when the house was being built. The grass in this area never turns as green as the rest of my yard. I usually water it more which helps some. This area also gets sun most of the day.
