With the hustle and bustle of the holiday season upon us, your lawn and landscape asked us to remind you they would also like to spend a little time with you this month.
Lawn Mowing – Warm-season lawn mowing wrapped up early in November while cool-season lawns still need occasional maintenance. The more and more nights with temperatures in the 20’s the more fescue lawns will slow down. Depending on weather conditions, you can expect fescue to put on some growth well into December. So, if you are a fescue lawn owner, don’t put your mower away just yet. Continue to mow as needed to keep the lawn clean and looking tidy.
Leaf Removal – Keeping leaves removed is recommended for all lawns, but critical if you have a cool-season lawn. If you remove leaves regularly, you will find mulch mowing them back into the turf is an effective way to handle clean-up. Fescue will completely die out under leaves. If you allow leaves to collect in the corners of a fescue lawn over the winter, those areas will be thin to completely bare next spring.
Remember - fescue lawns need light even in the winter.
Irrigation – Soil moisture, is a critical ingredient for your landscape’s winter survival, and the key determining factor if you should water or not over the winter. Soil moisture is currently good in the Oklahoma City area thanks to the occasional rains we have received over the past few weeks.
How can you know the soil moisture? www.mesonet.org is Oklahoma’s industry-leading website for weather and climate information. The 1-day Average 2” Fractional Water Index is a good guide to watering decisions.
Through the winter check the soil moisture regularly and compare the 7-day forecast. If the soil moisture is low and if there is no moisture forecasted in the coming 7 days, select a nice day to water. Most importantly, if my soil is dry, and the forecast has days below freezing, water thoroughly before the cold weather arrives.
Winter damage to our lawn and landscape occurs when the top 3” of soil is dry and temperatures are below freezing.
If you have a rain/freeze sensor on your irrigation system and your system is equipped with freeze protection on the backflow, we recommend setting your system to run one time per week through the winter. If the temperature is below 35, the sensor will not allow the system to run and if there has been a recent rain, the system will remain off.
Tree Trim – During winter dormancy, tree trimming is a great practice. As leaves fall and tree canopies are more visible, spend a few minutes analyzing the structure of your trees and start making plans for the next step of corrective pruning. We will cover tree pruning techniques in detail in the next few weeks.
Spring Bulbs – Mid-November through mid-December is the perfect time to plant spring flowering bulbs. Spring bulbs require extended cold temperatures to produce. If you procrastinate, you run the chance of not having a good color show next spring.
Mulch – Another great landscape practice for improving the survivability of your landscape plantings is a fresh layer of mulch. A 2-3” layer of mulch will provide insulation for your plant roots, retain moisture, and moderate soil temperatures. We recommend adding a layer of fresh cedar, pine, cypress, or pecan mulch after you do your final leaf clean-up of the season.
Soil Test – If your lawn, shrubs, or trees often look a little off-color and lack vigor, now would be a great time to check the soil pH and nutrients. Fill a quart-sized plastic bag with soil from at least six spots in the area of concern. Take soil from just below the surface. Remove roots from the soil. Use a separate bag for soil from your lawn and landscape areas. Take the soil sample to your local Oklahoma State University County Extension Office. They will test the soil and send you a report for a nominal fee. The Oklahoma County office is located at 2500 NE 63rd St., Oklahoma City, OK 73111.
Weed Control – If you have not applied the second fall/winter pre-emergent and broadleaf weed control to your lawn yet, it is not too late to do so. The goal of this application is to extend the prevention of weeds until the spring pre-emergent is applied.
Tree Planting – Tree farms are harvesting freshly dug trees now. Trees that are dug and replanted during dormancy have the best chance of survival. If you are thinking about adding trees to your landscape anytime in the next year, don’t wait till spring or summer, plant this winter.
Foot Traffic – Avoid walking on frozen grass. If is particularly damaging to fescue. Turf areas with winter foot traffic are slow to recover in the spring.
