St. Augustine Suffers From Bitter Cold
You might be looking at your St. Augustine lawns this spring and wondering “is my grass going to come back?” It’s a valid question this year, as warm-weather grasses have suffered significant damage from our very cold winter. St. Augustine is especially sensitive to the kind of freezing temperatures we experienced.
If you have St. Augustine, you might notice large patches of brown dead-looking areas in your lawn; or you may have damage across the entire lawn. Centipede grass has also sustained a lot of damage.
Lawns that are already weak, with shallow root systems, are much more susceptible to cold damage. Lawns that have been over-watered or under-watered are particularly sensitive. Too much shade is also a contributing problem.
Lawns that are stressed by any number of poor maintenance practices will suffer more cold damage as they go into winter dormancy. The healthier your lawn is before the onset of cold temperatures, the better able it is to survive them.
If you have patches of both live and dead St. Augustine, you’ll need to be a bit patient. You can allow the healthy grass to fill back into the dead areas, or you can re-sod the areas. Be sure never to use herbicides on new lawns. Now is an excellent time to feed the soil so that it can support new root growth for your lawn and landscape.
