recommendation for irrigation service
 

looking to get donuts around my sprinklers

Massey did mine for 5 dollars each, but was a few years ago. However, after a year of so they may disappear by sinking into the soil.

Note that it is an easy DIY project if you buy the right cutting tool.

Try digging around the sprinkler heads with a hand trowel...

You might find them under the grass...

Like said above, they do tend to sink into the grass and disappear...
