February Warm Season Lawn Tips for 2022

February Warm Season Lawn Tips for 2022

It's almost time for pre-emergent herbicide to prevent summer weeds from germinating! Not much else has changed for Bermuda, Zoysia, and Centipede lawns since December AND January.

Fertilizing Tips for Warm Season Lawns

  • Whatever you do, don't apply nitrogen this time of year when your warm season lawn is dormant. It's still time to rest. Avoid "weed and feed" and "winterizer" product marketing - these products usually contain nitrogen and nitrogen will push growth during a time that can cause cold damage to your lawn. 
  • It's okay to apply our 0-0-7 pre-emergent herbicide (to prevent summer weeds) since it doesn't have nitrogen in it. Nitrogen is the first number, in this case zero.
  • Likewise, hold off aerating warm season lawns until they fully green up in the spring.

Mower Tips for Warm Season Lawns

  • Nothing to mow this month, unless you need to mow any winter weeds that are thriving. 
  • If you have not done so already, "winterize" your mower by cleaning off plant debris, draining gas so it doesn't sit with stale gas all winter, and take the time to sharpen or replace your mower blades. Now is a good time to go ahead and take care of the blades so your mower is prepped for spring mowing.

Preventing Summer Weeds in Warm Season Lawns

Forsythia is the signal!

Forsythia signals it's time to apply pre-emergent herbicide because the soil is the right temperature.

What's a Forsythia? It's that bush with yellow flowers that typically flowers in the middle of February.

The rule of thumb is to apply spring pre-emergent herbicide when Forsythia starts blooming. In a typical year, if you don't have a Forsythia bush to signal you, apply pre-emergent between February 15th and March 1st to kill weeds before you even see them. Any later than that window and it's too late to kill weeds with a pre-emergent herbicide (you'll have to switch to a post-emergent to apply directly to the weeds).

We highly recommend going ahead and ordering so you have it ready when it's time to apply it.

Getting Rid of Visible Weeds in Warm Season Lawns

  • Right now, the best solution for winter weeds is pulling them by hand. This may not be what you want to hear. Happily, there is hope for preventing a weedy infestation next winter and Clare explains the steps in Tackling Winter Weeds.
  • If you have a bad infestation and don't want this to happen again, sign up for Lawn Coach and we'll mail you pre-emergent herbicide in September to prevent winter weeds from germinating next year.

  • Mow your weeds. If you didn't apply pre-emergent in September to stop the weeds you're seeing now (such as chickweed and annual poa), mow those weeds down. Or, turn on your Automower robotic mower to do the mowing/weeding for you when you'd rather not be out in the cold.
  • Post-emergent herbicide in Warm Season lawns: Weather permitting, you can apply post-emergent liquid herbicides like Quincept and 3-Way Max for weeds you can see now in established warm season lawns. These post-emergents work best above 65 degrees so they will work if we have any other extended warm spells like we did in December. Read the label and follow instructions.
  • Mulch suppresses winter weeds 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. Rake/blow leaves off your lawn and into your beds and natural areas rather than bagging them.

Lay Dormant Sod in February - Go for it!

If bare spots are driving you crazy or you have made renovations, you can stop all that mud by laying dormant sod.

No problem! Laying dormant sod in winter is "a thing."

In fact, the pic at the tippy top shows newly laid dormant sod - see all the seams still showing? We do recommend you read our article on laying dormant sod for a few important tips.
