Key Features and Benefits

Seasonal Summer Guide and Care

Mowing

Cobalt mowing heights during the summer generally range from about 2.5–3.5 inches. When mowing during the summer, never remove more than 1/3 of the leaf blade at a time.

Watering

Do not overwater the grass. Cobalt only needs about 1 inch of water weekly. Water for longer periods of time, less frequently and in the early morning hours. Take rainfall into consideration.

Fertilization

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.

Weed Control

It is not recommended that you apply an herbicide at this time. Once temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass.

Insect Control

If drought symptoms or yellow spots occur in a sunny location, check for chinch bug activity. Other insects to look out for are grub worms, mole crickets, sod webworms, and fall armyworms.
