First time my Saint Augustine is producing long unattached runners. Cause??

Question

I am pulling these sprouts, but is this a sign of fungus or root rot?
How to treat??

Answer 1

Apparently the grass runners won't reproduce on dry soil, thatch or compacted soil, so they keep stretching. Prevention is proper mowing height, about 2 1/2 inches, proper fertilization, avoid overwatering, and adding a light helping of compost to the lawn in spring to aid soil health.
