November Warm Season Lawn Tips for 2022

November Warm Season Lawn Tips for 2022

Did you wake up to frost on your lawn in October? I did four nights in a row!

As a result of the light frosts, my Zeon Zoysia lawn is partially green and partially dormant brown (like in the header picture showing perfectly healthy, but dormant-ish new TifTuf sod).

Your lawn may have that half asleep look too - don't worry, it's normal for this time of year.

Another normal phenomenon is Jack Frost trails. These trails pose no problem for your lawn, merely they are fascinating patterns left behind as cool air settles on ground that is still warm. To learn more about how Jack Frost trails happen, read Iris' blog post on Jack Frost Trails in Lawns.

Looks like the Southeast will have a couple of mild weeks ahead with no frost in the forecast. It's possible that your lawn may start greening up again, so keep mowing it to prevent leggy growth and considering turning on the irrigation if your established lawn needs it (always keep new lawns watered until roots form).

🍁 Get out your rake because leaves are gently tumbling from trees and piling up on lawns. Remove those pretty fall leaves off your lawn so they don't smother it. This time of year, I'm out there every few days blowing them off before many accumulate.

Fall Fungicide Application

If you haven't done so already, warm season lawns get an application of fungicide in the fall (once soil temps lower to 70 degrees) to help reduce the possibility of Large Patch. Remember an ounce of prevention in the fall is cheaper and easier than curing Large Patch in the spring!

Fall Armyworm - Threat Downgraded Due to October Frosts 

In October most areas of the Southeast had several nights with frosts, so Fall Armyworms are likely no longer an issue. If you're in a warmer, frost-free area continue to keep an eye out for signs and symptoms. If you flush them out with a soap test, scoot on over to get preventive and curative insecticide from us. 

Fertilizing Tips for Warm Season Lawns

  • Don't fertilize! Do not fertilize, topdress, or aerate warm-season lawns anytime in the fall; wait until spring. Let your lawn go dormant. High nitrogen promotes tender new growth that can be damaged by frosts, so don't use high nitrogen fertilizers and save yourself the fright.

Mower Tips for Warm Season Lawns

  • Continue to mow warm season lawns at the recommended height until they go dormant. It's critical to keep up this practice to prevent leggy growth so that your lawn looks great next spring.

Getting Rid of Weeds in Warm Season Lawns

  • Right now the best method to combat weeds is to mow them before they go to seed. Mowing is an effective way to suppress weeds because it cuts off flower/seed heads and that stops weeds from making more weeds, thus breaking the life cycle. If you have bad weeds, mow on a weekly routine and don't let the weeds get ahead of you.
  • The window for applying pre-emergent herbicide is closed for the autumn. The next window will open in February when the Forsythia bushes flower - we'll send out an email alert at that time. Now is the time for post-emergent herbicides for weeds you can see now on all established lawns. 
  • For weeds you see now in established lawns, apply post-emergent liquid herbicides like Quincept and 3-Way Max. Read the label and follow instructions.

    👍 Rule of Thumb:
    It's okay to apply a post-emergent liquid herbicide after you've mowed your new lawn 3 to 4 times.
  • Pulling by Hand: If some weeds have escaped your pre-emergent routine and regular mowing, we recommend hand pulling to build up arm strength for cooking that big Thanksgiving meal.
  • Mulch suppresses weed seeds in flower beds. Spread your favorite mulch 2-4" thick and keep it 1-2" away from touching the trunks or stems of your plants.
