The best time to plant grass seed in South Dakota depends on the type of grass you’re working with. For cool-season grasses, aim for mid-August. For warm-season grasses like buffalograss, May to June is ideal.
Now, let’s dive into the details so you can give your lawn the best chance to thrive.
Best time to plant grass seed in South Dakota
The ideal time to plant cool-season grass seed in South Dakota is mid to late August. The earlier you plant during this window, the better your grass will establish before winter (starting around August 15 is best). This time frame ensures optimal growth conditions as temperatures start to cool. Kentucky bluegrass is the best choice for most areas of the state.
Plant warm-season buffalograss from May to June, when soil temperatures are warmer. Buffalograss is a native grass that is well-suited for drier regions of South Dakota.
When to overseed in South Dakota
If your lawn is looking a little worn out after a tough year, overseeding can be just the thing to bring it back to life. In South Dakota, the sweet spot for overseeding cool-season grasses like Kentucky bluegrass is mid August, but plant no later than September 7 to 16, or at least two weeks before the first frost date in your area.
This timing gives the grass a head start, letting it establish strong roots before the first frost. To pinpoint the first frost date in your area, check out your region’s fall frost date online.
For warm-season buffalograss, the best time to overseed is from May to June. This way, the grass has all summer to grow and thrive in the warm weather.
