The calendar may still say summer. But in Colorado, the thermometer is already saying fall-ish.
We've noticed daily highs getting cooler and the daylight hours getting shorter. But did you notice the much cooler nights?
Right now, average night-time low temps are more than 10 degrees cooler than they were on August 1st. Cooler night-time lows mean fall is in the air and especially so, for the lawn. Cooler nights combined with fewer hours of daylight slows lawn growth considerably. And that means it's really time to crank down the water and soon, slow down the mowing.
Grass in fall mode needs less water and less mowing the closer we get to the official start date of fall in just a couple weeks.
Even with the grass slowing down, you still need to love your lawn a little longer this growing season with a bit more TLC. Do these fall lawn activities and you will build a hardier lawn for the winter and see a stronger come-back next spring.
- Apply a final application of fertilizer timed around the first day of fall, September 23rd. Using the same fertilizer you used earlier this season is fine. But if you need to buy more, look for a formulation high in Nitrogen and Potassium because these minerals are good for the roots.
- Core aerate the lawn before winterizing the sprinkler system. Aeration pulls plugs of soil and sod out of the lawn and these holes open up the soil so that the roots can take in maximum moisture during the winter.
- Zap turf weeds. Here's your last chance for this year to get after turf weeds. Giving one last round of control will really pay off next spring in terms of fewer weeds at the start of the season.
- Get expert help if you have had fungus or other turf disease or insect problems this summer.
