As predicted, the first three weeks of winter have been cold and wet. With the forecast calling for more of the same, here are a few helpful tips to ensure the health of your lawn and landscape.
A half-inch of rain is more than enough water to sustain St. Augustine and Zoysia turf during the winter months. This is equivalent to running your irrigation once every 10-14 days. Save yourself some money by turning your irrigation clocks off when we have these weekly rain events. Shrub zones on your irrigation controller can be completely shut down for the next two months.
Be sure to cover any cold-sensitive plants with frost/freeze cloth or old bedsheets on nights frost or freeze is forecast. Avoid the use of plastic sheeting for covering plant materials; these coverings act as a magnifying glass at sun-up and can burn plant leaves. Please contact us
if you have questions regarding a plant's sensitivity to cold. Most importantly, if you are running your irrigation, make sure your controllers are shut off on nights of forecasted frost or freeze.
Though frosts or freezes are frowned upon here on the Sun Coast, they can be of some benefit to your landscape on two fronts:
1. Frost/freeze can greatly reduce over-wintering insect pests that would typically flair in spring; and
2. Frost/freeze can kill or retard certain weeds in your turf (e.g. carpetgrass), weeds for which there are currently no chemical controls available.
So there is a silver lining to this weather! Stay warm, and Happy New Year!
