CENTIPEDE DECLINE

Failure to green-up in the spring or successful green-up followed by decline and death in late spring and summer is a problem that can be encountered in centipede grass.  Healthy above ground growth depends on an extensive, well-developed, deep root system. The weaker and less extensive the root system, the more susceptible the grass is to drought stress and winter injury. In extreme cases, the root system may be so weakened that the grass will die even during favorable summer weather conditions. A number of factors can contribute to poor root development, including nematodes, compacted soils, nutrition problems, and poor watering techniques.

  Preventive and  

 Corrective Measures  

*  Was the grass turning yellow as it greened-up in the spring or when it went into dormancy in the fall ?

- You may need us to take a soil test.  Nutrient imbalances such as low or excessive phosphorus may be the culprit.

*  Was the grass dark green during the previous growing season?

- The correct Centipede coloring is light green.  If a Centipede lawn remains dark green for the majority of a growing season,  this indicates an excessive use of nitrogen.

*  Can the turf be easily lifted from the soil?

- This is a sign of a poor root system.  A poor root system can be caused from compacted soil, improper watering or mowing, drought stress, nematodes, or excess thatch.

*  Is it difficult to push a soil probe, screwdriver, or shovel into the soil?

-  This is a sign the soil is compacted.

*  Do the grass blades turn dull green and curl up during dry weather?

- Drought stress may be caused from improper watering, compacted soil, poor root development, excess thatch, or nematodes.

Large patch

Large patch is a fungal disease.  It shows up as round, discolored patches that expand over time. The borders of the patches are sometimes orange, and the centers appear brown and sunken. This disease is most likely to be observed from November through March when temperatures are below 80°F.  Infection is triggered by rainfall, excessive irrigation, or extended periods of high humidity resulting in the lawn being continuously wet for 48 hours or more.  

As ugly as Large Patch can look, it’s important to remember this disease does not kill the entire grass plant. 

  Preventive and  

 Corrective Measures  

Once the weather warms up, your lawn will begin to grow.  With correct mowing practices, the large patch will grow out.

Because large patch is caused by excessive wetness, we recommend adjusting your sprinkler system.  When doing so, please take rainfall into consideration.

If our lawn technicians notice large patch on a lawn, they will apply Potassium to help strengthen the root system.
