County of Citrus recently issued the following announcement.
Cool it in the Garden this Fall By Steven K. Davis, Citrus County Florida-Friendly Landscaping Program Coordinator Plant growth and needs diminish as cooler weather prevails.
Take this opportunity to do “less” in the landscape, discourage active plant growth, and reduce winter losses. First, plants need less frequent watering during the cool season when
transpiration and evaporation is slowed. Extended periods of moisture promote weeds, pests, and diseases. Less water means less
opportunity for garden nuisances to thrive while the landscape is napping. As temperatures drop in December, January, February and sometimes November, adjust irrigation to
every other week. Consider manually operating the irrigation system during the winter by turning the system to the off position and back on only when two weeks of no rainfall has
passed. This will also help keep plants dry during freeze events.
Next, refrain from applying nitrogen-containing fertilizer until spring. Warm season lawn growth slows after September and moves toward dormancy as the threat of frost
approaches. The last opportunity to apply nitrogen-containing fertilizers was September. However, potassium is an option when applied correctly in fall. This macro-nutrient
promotes a hardy plant cell wall and aides in root production. Mow grass at the highest possible height to further insulate roots from cold. Iron
is a greening option for the winter lawn, as well as annual ryegrass. Keep in mind that while ryegrass does not qualify for additional irrigation in Citrus County, it easily germinates
with Florida’s abundant nighttime dew. Additionally, pre- emergent herbicides prevent germination of several winter annual weed seeds. When properly applied, these products
reduce surging weed populations and are less able to injure healthy slow growing or dormant grass.
Lastly, when installing cold sensitive plants, choose protected locations. Find or create areas that are shielded from frost and cold winds. Consider spots near or between structures
and under tree canopy. Avoid locations at the bottom of slopes or small basins. Scientists focus on cold hardiness when breeding plants. Benefit from their efforts by selecting the right plant for the right place.Landscapes need time to rest as temperatures cool. Forcing landscapes to actively grow and demanding green lawns in Florida winters contributes to
plant injury and costly renovation. Applying nutrients during the appropriate months, selecting the “right plants,” and conducting proper seasonal care will reduce plant losses during
North Central Florida winters.
