March Lawn Tips

If you haven't already done so this year, it's time to get pre-emergent herbicide on ESTABLISHED turf. Come by Super-Sod for the products you need.

Notes on so-called "weed & feed" products:
  1. We recommend a combo "weed & feed" product with nitrogen (N-P-K ratio ex.: 26-0-3 or 15-0-10 or 25-0-0) during the cool months on Tall Fescue, but . . .
  2. We don't recommend a "weed & feed" with nitrogen on warm-season lawns (Zoysia, Bermuda, Centipede, St. Augustine) in any region during the cool months if the "weed & feed" contains nitrogen (most of them do), because . . .
  3. Nitrogen on a warm-season lawn in late winter will probably cause cold damage to a warm-season lawn by promoting early spring green up before the average last frost date;
  4. Plus, the nitrogen in a typical "weed & feed" is extremely high as shown in the label examples above and Zoysia/Centipede vs. Bermuda have very different fertility requirements (1-2 lbs. nitrogen per year for Zoysia and Centipede vs. 4-6 lbs. for Bermuda) and it’s hard to control the correct nitrogen distribution when broadcasting a "weed & feed."
  5. If a "weed & feed" is applied to a warm season lawn after spring green up, it's actually too late to control the spring weeds!
  6. For weed control on warm season lawns we recommend a late winter application of a pre-emergent herbicide without any fertilizer (a stand alone product) or a "weed & feed" that contains potassium (0-0-7 on the label) rather than nitrogen.
Fertilizing Fescue: For Fescue in the spring, we recommend fertilizing with our 16-4-8 +Iron.

Fertilizing Warm-Season Lawns: Don't fertilize your warm-season turf too early. You can damage your lawn if it greens up and starts growing too quickly. Wait until May 1st to make sure we are out of the frost danger zone and the soil temperatures have warmed. Organic Tip: When the time comes, topdress your lawn with Soil3 to supply organic fertilizer and build healthy soil under your sod. Order a BigYellowBag of Soil3 now to get the discount and have it at-the-ready when it's time to topdress.

Scalping: We recommend that folks wait to scalp warm-season lawns until pre-emergent has been applied and watered in well. Mowing off the “canopy” before pre-emergent is applied can result in earlier weed germination.
