For all its beauty, St. Augustine grass seed has many weaknesses. It does not tolerate cool temperatures well and can be easily damaged by prolonged exposure to cold air. Although it will grow in partial shade, its performance will be moderate at best if the temperatures drop too low without the benefit of adequate sunlight.
This type of grass seed is extremely vulnerable to both insect damage and disease, including St. Augustine Decline Virus. SADV can damage large areas of lawn that contain it. Gray leaf spots and brown patches can also occur throughout lawns where the virus has been a problem.
Chinch bugs are also a problem for this type of grass seed. An infestation of chinch bugs is characterized by the browning of the leaves as well as rapid wilting.
A large infestation can cause brown patches in a lawn that are several feet across. In some cases, depending on the severity of the problem, yellow spots may also be a sign of chinch bugs. Repeated applications of insect repellant may be needed to stop and then control the infestation of chinch bugs.
St. Augustine grass has broad, coarse leaves and stems that are large and flat. It grows rapidly during the warm, summer season and will become dormant as the weather becomes cooler, causing it to turn brown and growth to cease.
With its blue-green hue, this type of grass creates a lush, thick lawn with a dense turf base resembling a solid grass carpet. This particular grass seed grows extremely fast and requires frequent mowing to keep it looking plush and full.
It should not be planted in areas where the temperature drops below freezing in the winter months. The seed flourishes in temperatures that hover around 85 to 90 degrees but struggles when temps fall below 40 to 50 degrees for prolonged periods of time.
Although states in the southern portion of the country experience cooler temperatures, they do not last long enough to cause lasting damage to lawns and golf courses seeded with this type of grass.
Professional lawn care experts suggest using less than 4 pounds of nitrogen-rich fertilizer for every 1,000 square feet. Excessive watering and too much fertilizer can create an abundance of thatch that can build up and hinder growth. If allowed to remain on the lawn, excessive amounts of thatch can lead to insect infestation and the spread of diseases that primarily affect this type of grass.
Pre-emergent herbicides can also damage this particular breed of grass. 2,4-D, MSMA and other herbicides in the pre-emergent family can directly impact the seed’s growth and, in some cases, damage the plant base beyond repair.
When using any type of herbicide, insecticide or fertilizer, always make sure to follow the directions on the package closely to prevent damaging the existing grass. If there are any questions concerning when to use a specific product or how much to use, ask a plant professional at a local green house or call the information number on the back of the package.
