March's Lawn Tips Live was filmed at Super-Sod of Greenville, South Carolina. Join our turfgrass trainer Greg Nichols as he explains how to care for your warm and cool season lawns. Toward the end Super-Sod's Marketing Director, Hillary Thompson, shares her knowledge about March's featured weed, hairy bittercress.

Tall Fescue's Time to ShineDuring these final cool months, Tall Fescue is the brightest green carpet around.
- It's still a great time to lay Tall Fescue sod. Get instant impact with Elite Tall Fescue sod, available as a single roll or in full pallets. You can order sod online.
- Overseeding Tall Fescue - This window has closed. To successfully seed Tall Fescue wait until autumn.
- Continue to mow as needed throughout the winter at a 2.5-3" cut height. In summer we'll remind you to raise it up again.
- Stop in to pick up 16-4-8 fertilizer for Elite Tall Fescue lawns through the cool growing season. Check out our Lawn Coach subscriptions for Tall Fescue products.
- Along with fertilization, you may need to apply lime to neutralize the pH of your soil. Always take a soil test to confirm if you need to apply lime or fertilizer.
Update for March: When it warms up later in spring, back off on fertilizing Tall Fescue for the summer. Now, while it's still cool out, it's a great time to topdress Tall Fescue with Soil³ compost to take the place of one fertilization. It's too late to aerate, but you can still spread compost and we rent compost spreaders. Plus, we have a deal on Soil³ to encourage you to topdress with compost.

Warm Season LawnsNot much going on in this department since your Bermuda, Zoysia, and Centipede lawns are still dormant. In the warmest regions of GA, NC, and SC, your lawns may start waking up toward the end of the month.
- Whatever you do, don't apply much nitrogen yet. Avoid "weed and feed" and "winterizer" products because they usually contain high nitrogen that will push early spring growth that can be damaged by late frosts. It's okay to apply 0-0-7 with pre-emergent to established lawns or 5-10-30 to new lawns, but hold off on high nitrogen until your grass fully greens up in the spring.
- Likewise, hold off aerating warm season lawns until they fully green up in the spring.
- Mow your weeds. If you didn't apply pre-emergent in September to stop the weeds you're seeing now, mow those weeds down. Or, turn on your Automower robotic mower to do the mowing/weeding for you. Here's a robot friend mowing a dormant lawn in North Carolina.
Forsythia - the bright yellow bush we talked so much about in February's lawn tips - is the signal for applying pre-emergent herbicide. In northern areas of GA, NC, and SC, Forsythia is late in flowering because it's been cooler. Come by for products or check out our Lawn Coach subscription.
- Pre-emergent: It has remained cold out so there is still time to apply pre-emergent herbicide to kill summer weeds. It's probably too late to stop crabgrass from germinating, but if you haven't yet applied pre-emergent, there's still time to suppress many other weeds. The window is closing though, so act soon. Come by for products or check out our new Lawn Coach subscriptions.
- POST-Emergent herbicide on NEW Tall Fescue: If you planted a brand new Fescue lawn from seed and in the process tilled up existing soil, you've probably kicked up weed seeds and exposed them to the light. As a result, the seeds are probably now germinating alongside your Fescue seedlings.
👍 Rule of thumb: It's okay to apply a post-emergent herbicide labeled for Tall Fescue lawns after you've mowed your lawn 3 to 4 times. Come by for products or check out our new Lawn Coach subscriptions.
- Mowing works well for suppressing weeds you see now.Mow to break the weed life cycle. Mowing cuts off flower/seed heads and that stops weed seeds from making more weeds. Get yourself on a weekly mowing routine and don't let the weeds get ahead of you. Better yet, a robotic lawn mower will quietly and constantly mow for you and keep the despised weeds from going to seed - It's a clean and green, weed-stopping machine!
- Mulch is a time-tested trick for suppressing weeds in flower beds. Spread bark or pine straw 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.
- Hand Weeding - Plop yourself down on the ground and pull up some weeds. You'll feel the calming earth through your fingertips and get Vitamin D through your skin.

Brie's Gardening Ideas for February
These are technically gardening ideas for last month, but March is young and these tips are still good ones to hop on.
Installing Sod During Winter
Cold-loving Elite Tall Fescue sod is ideally laid during winter, but many types of dormant sod, especially TifTuf Bermuda and Zenith Zoysia, can also be installed in winter.
