NorthBridge® Bermudagrass Maintenance

NorthBridge Bermudagrass mowing heights during the summer generally range from about 0.5–1.5 inches. When mowing during the summer, never remove more than 1/3 of the leaf blade at a time. If you remove more than that, you will stress the grass and it may go brown for a short time. Taller blades provide more shade for your root system to stay cool and retain moisture during the hot summer days. If you are returning from vacation, you may have to mow multiple times to get the grass back to the desired height. Wait about three to five days between each mowing.

Do not overwater the grass. NorthBridge Bermudagrass only needs about one inch of water weekly. Water for longer periods of time, less frequently and in the early morning hours. Take rainfall into consideration.

For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi’s Summer Fertilizer Box or apply Lawnifi Foundation once every three months.

It is not recommended that you apply an herbicide at this time because when temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass. Common weeds to look out for include white clover, crabgrass, goosegrass, knotweed, lespedeza and spurge.

Check for and control any white grubs. Apply Merit to prevent grub worms and apply GrubEx or Dylox 6.2 to treat grub worms. If you use a granular variety, water the lawn immediately after application to help soil absorption. Calculate that watering into your weekly watering amount. August is the best time to control grubs because they are small and feeding near the soil surface. Other insects to look out for include billbugs, mole crickets, chinch bugs and nematodes.

Treat with a broad-spectrum fungicide like Heritage if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. Calculate that watering into your weekly watering amount.

During the fall, mowing will occur less often—keeping your NorthBridge Bermudagrass slightly higher will encourage deeper root growth for winter.

Water less as temperatures drop—too much water will lead to disease. Water to prevent drought stress while grass is actively growing and after the beginning stages of dormancy to prevent dehydration.

For fall fertilization, apply less than half a pound of nitrogen per 1,000 sq. ft. to minimize spring dead spot. For optimal results, feed your lawn during the fall season by applying the Lawnifi Fall Fertilizer Box. The Fall Fertilizer Box was designed to help your grass recover from the heat of summer and prepare for winter dormancy.

Apply pre-emergent herbicides to control winter annual and perennial weeds like chickweed, henbit, Poa annua, crabgrass or goosegrass. Apply post-emergent herbicides only when weeds are present.

Check for and control any white grubs. Treat with an insecticide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption.

It is recommended you apply a fungicide at preventative rates as this will help the grass enter colder months in a healthier condition. If you have had a fungus before, you may need multiple applications in affected areas. If spring dead spot was a problem, apply a fungicide at high rates to the problem area(s). Consider mapping those areas because fungicide treatment can be expensive. If you use a granular variety, water the lawn immediately after application to help soil absorption.

For the first mow of the spring, remove dormant grass leaves to promote new growth by dropping your mower down a notch and giving it a “buzz-cut” with a rotary mower that has a sharpened blade. Bag up all the material to keep excess clipping from clumping or causing disease.

After your initial “buzz-cut”, begin mowing your NorthBridge at the desired height of .5–1.5 inches.

Don’t overwater. In the active growing season, NorthBridge needs about one inch of water a week from natural rainfall or irrigation. If you apply any granular fertilizer or control product, you will need to water it in. This is a sufficient amount of water for the week. Overwatering may promote disease outbreak. Conduct an irrigation audit to evaluate how much water is being delivered to different areas of your lawn.

For optimal results, feed your lawn during the spring season by applying Lawnifi Foundation, a granular fertilizer.

Apply a pre-emergent herbicide when soil temperatures reach 55 degrees Fahrenheit. This will prevent summer annual weeds like crabgrass and goosegrass from plaguing your lawn and garden. Apply post-emergent herbicides in May as needed to control summer annual and perennial broadleaf weeds like white clover, knotweed, spurge and lespedeza. Products containing multiple broadleaf active ingredients are more effective in controlling broadleaf weeds.

Apply a broad-spectrum insecticide to prevent spring insects from appearing or to control any current spring insects like chinch bugs, billbugs, mole crickets or white grubs. White grubs may be active at this time. If you see any white grubs, apply a systemic insecticide.

Apply a systemic fungicide at a preventive rate to keep disease from taking hold of your lawn. You may begin to see circular patches of brown or dead grass as your NorthBridge begins to green up. Do not apply fertilizer until you’ve applied a systemic fungicide at a curative rate and your grass has recovered.
