    2 Steps to a successful overseeding campaign

    Managing bermudagrass for 'winter color' means overseeding in the fall. For the homeowner and landscape professional. this process requires considerable time, effort, and money to produce the successful project. To assist with this effort, Barenbrug and Texas A&M University have developed a revolutionary new concept in overseeding.


    Welcome to Super Over Seeding - a two step process to ensure beautiful green turf all year long without the added stresses of increased chemical usage or poor transition of cool season grasses. If you want a successful over-seeding project and a beautiful winter lawn there are two critical components that must be taken into account.


    Step 1 - When does your bermuda typically green-up in the spring and your 'winter rye' transition out - Identify your climatic region.
    Where you are and how many days per year you have above 90 degrees are critical to good establishment and timely transition of your 'over-seed'. Knowing your climatic zone is not enough though. Within your climatic zone lie micro-climates that can affect the transition speed of your 'over-seed' as well as the recovery of your bermudagrass. If you've seen your overseeding product transition out too early or last too late into the spring you need to move to the next step in overseeding.


    Step 2 - Adjust your transition speed based on your micro-climatic needs.
    Need your cool season grass to last a little longer into the season - choose a slower transitioning product. If your cool season grass typically lingers - choose a rapid transition solution. It's that simple. And if that's too complicated - just use the ideal SOS solution - pre mixed for your needs.

    Today's lawns require turfgrasses needing lower maintenance costs and overall inputs. Lower water use, less fertilizer required, fewer clippings, and agressively competing with weeds during establishment are all traits that set varieties from Barenbrug USA apart from the competition.
