February and March were active for many different diseases and winter-related injuries on turf and ornamentals. We were experiencing areas of Yellow Patch, Dollar Spot and Damping Off diseases on Tall Fescue. Some lawns received damage to portions of the lawn in a short period of time requiring repair; others appear to be recovering well.
At the time of this writing, we had not seen signs of Large Patch Fungus or winter injury on warm season turf. However, damage may have occurred on all warm season turf on March 28th when night time temperatures dipped into the upper 20’s. Bermuda, Zoysia, Centipede and St. Augustine started transitioning out of dormancy the prior couple weeks due to warmer soil temperatures and could have setup these grasses for potential injury. We will know more in the coming weeks. Warm season winter injury can be wide spread or just in micro-environments.
Many ornamental shrubs have received winter injury. A few varieties showing worse injury are Gardenia, Azalea and Loropetalumn. However, there are many more showing different levels of winter injury. Most should recover in the coming months.
Crabgrass will usually start to germinate in late March or early April throughout the Transitional Zone. Germination will occur when soil temperatures are between 53 to 58 degrees and 3 to 4 inches deep. Crabgrass germination will be seen first in bare spots with little desirable turf and in full sun. Split applications of pre-emergent Crabgrass control perform well. There is still time if you missed your first application of pre-emergent to control a fair amount of Crabgrass, but you must act quickly.
Mowing season is underway. Proper mowing height will help control weeds in the lawn.
Research has proven that maintaining a mowing height of 3½ – 4” on fescue drastically reduces the amount of crabgrass in the lawn. Mowing at this height will also help promote healthy turf and hold back broadleaf weeds.
Many warm season turf lawns struggle to strive due to improper mowing height. Mowing your type of warm season turf will drastically improve the overall quality and appearance of the lawn. Bermuda in a home lawn requires mowing every few days at .5” to 1.5”. Mowing at this height encourages denser turf and spreading. The lawn will look thin and grow upward if mowed above this height. In addition, it lowers the quality of the grass increasing the possibility of damage. Zoysia requires a mowing height between 1.25” and 2.5” based on your particular variety. A safe bet would be around 2” to 2.5”.
Centipede needs to be cut low around 1” to 1.75” to perform well. St Augustine requires a mowing height of 1.75” and 2.25”.
