Soil Quality:

It might be because the soil conditions are not conducive to its growth. When you have sandy soils, it can be too dry and when you have clay soil it can hold onto the water but lack earthworms to aerate this type of soil properly. You need to improve the quality of your soils before bringing life back into these dead patches by planting new st Augustine seeds.

Pest infestation

Pest infestation:

One of the most common reasons for St Augustine grass to not grow back is due to pest infestation. When you have pests such as grubs, mole crickets, or billbugs in your lawn it can really inhibit its growth. This will cause damage directly to the soil and prevent new seeds from growing through it, which means that you won’t get any regrowth at all.

Getting rid of these insects should be your first port-of-call when seeking a solution for how to get st Augustine grass to grow back again.

Frost damage

Over the winter months, St Augustine grass is susceptible to frost damage. Just like most other plants and flowers in your yard, it can’t handle cold temperatures for extended periods of time which will kill off these patches entirely so you won’t be able to get regrowth at all here. If you have problems with frosts regularly during this time, then choose a different type of grass that doesn’t die back over Winter.

Dormancy

St Augustine grass is a warm-season species of turf so it goes dormant during the winter months. This means that there won’t be any growth, but this isn’t always an issue unless you have problems with frost damage or pest infestation which are two things that can cause significant issues for how to get st Augustine grass to grow back again after dormancy. Dormant patches will eventually recover when Spring arrives and they can resume growing normally once more if all other factors aren’t impacting their ability to do so!

Drought stress:

St Augustine grass is a resilient type of turf and can handle periods without water, but this has to be done in moderation. If the soil becomes too dry for an extended period it will cause irreversible damage which means that you won’t get any regrowth even if it rains again. For how to get st Augustine grass to grow back after drought stress, make sure that your irrigation schedule isn’t overwatering the soil (which also causes issues) and keep on top of any rainfall during hot days when there’s no rain at all otherwise you’ll end up with dead patches everywhere!

Fertilizer burn:

If you use too much fertilizer on St Augustine grass then it can cause burn damage. You need to stick to the recommended rates or lower as anything more than this will start causing issues for how to get st Augustine grass to grow back again after fertilizers have been used by mistake!

Brown Patch diseases

Brown spots can be found all year but are more prevalent during warm weather. The best defense against Brown Patch diseases is to irrigate regularly so grass blades are not stressed, especially when it’s hot and sunny outside.

St Augustine Grass Diseases

Powdery Mildew

Powdery Mildew only occurs in hot humid climates from July through September if overhead watering or rainfall is excessive.

Gray Leaf Spot

Gray Leaf Spot happens in the transition seasons between early spring and summer with moderate temperatures of 60 degrees Fahrenheit or higher for long periods of time. It does not need free moisture for spores to germinate.

St Augustine grass Mowing:

Maintain a height between two and four inches on your St Augustine blades, but do not cut it shorter than three inches as this can slow growth down. To promote healthier plants, mow more frequently when they are young, which means every few days during periods of rapid growth.

Fertilizer:

Apply a fertilizer designed for warm-season grasses with a ratio of two to three times more nitrogen than potassium and phosphorus.

Fertilizer:

Grass Seed:

A mixture of one part fescue seed, four parts Kentucky bluegrass, and five parts perennial ryegrass is good in stabilizing overseeded St Augustine lawns. Some homeowners prefer using zoysiagrass because it grows faster but when the weather turns cold the st Augustine will die out while zoysia can survive by going dormant during wintertime conditions.

If you use an insecticide make sure to spray beneath blades of lawn where insects rest during the day so they don’t avoid being targeted by these chemicals.

Fungicides:
