Lawn mystery

Pearland, TX(Zone 9a)

Hey everybody, I need some wisdom. Here is the deal.. My yard, which is ST Augustine, has strange areas that are lifting up from the soil, yet still growing. If you walk on them, the area presses down, then springs back up. I have a sprinkler system connected to the sewer. However, the problem is not around all the heads, just one. The ground under the patch is loose, and I did not see any bugs in it. Another strange thing: all over the yard single stolons are coming up, growing over a few inches of the other grass, then reattaching themselves. I think in general the front yard is weird!! I do not see any of this in the back. Hopefully the pictures will help. I live south of Houston with the famous gumbo soil. Thanks for any advice. First picture is of the stolons.

I have no idea why you are having "Loose" areas of grass unless this area is getting and staying too wet?..As far as the Stolons growing over and reattaching themselves..that is quite common with St. Augustine Grass ..I have the same thing..eventually it just covers over itself if the Lawn mower doesn't get it first....Jeanne

cap, do you feel tunnels? I have similar problems and I have moles EVERYWHERE!

I was going to say the same thing about the stolons, and I certainly count on that behavior to get the grass to spread.

The loose patches are wierd. If no one comes up with anything, I'd call the extension office tomorrow.

stolons are common and are part of the growth process. I have a neighbor that comes by and pulls my stolons and plants them in her bare spots. They're taking off and doing great! The ones she doesn't pull usually get whacked with the weekly mowing.

As far as the spots, have no idea, but one guess would be critters digging for roots/bugs and leaving spots soft.

I think your lawn looks pretty nice and is probably the envy of many around you.

Thanks everyone!! I know we do/did have moles, because my cats bring them in the house. I will keep a look out for other critters.

I agree with everyone else about the stolens. I think it is too early for grub damage but that is exactly what happens to the grass when they have eaten the roots. It still looks good on top but you can pull it up from the soil.

if it is grubs, HD, lowes and bigger garden centers sell a product to apply to lawn for grub control. you're supposed to spray right around this time of year. Bottle will say something like "grub control", there are various manufacturers. I bought 4 bottles last year on sale (hope they're still good) and it is in my "short" list of things to do. Regular price $6-7.

You can also buy it in granular form to use with spreader.

Dillies do that here. Are you Dilly fenced?

Willis, TX(Zone 8b)

I am afraid to ask what a "Dilly" is..lol

Santa Fe, TX(Zone 9b)

They look kind of like turtles with a pig snout and rabbit ears. Sometimes called Roadkill.

My Daddy always called "Armadillos" Roadkill..now I really am confused..LMAO...Jeanne

And there is a place on Hiway 6 that sells "Dilly" burgers. I have never eaten there.
