Zoysiagrass Becoming More Popular in the Panhandle

Zoysiagrass Becoming More Popular in the Panhandle

If you’ve been researching lawn grass options recently, you’ve probably come across a not so traditional variety known as zoysiagrass. There’s no mystery why zoysiagrass has become a hit with lawn enthusiasts in the Panhandle. This variety is a great choice for coastal, warm weather climates. However, there are always management practices that need to be carefully considered, before deciding on a lawn grass variety.

Zoysiagrass was introduced to the U.S. from Asia around the early 1900’s. The grass has mostly been used for turf applications, especially on golf courses and other athletic fields. However, in recent years, breeding advances have made this variety a viable option for homeowners. Some of these improvements involve insect resistance and fast establishment periods.

Except for one species, zoysiagrasses must be planted by sod, plugs, or sprigs. Zoysia japonica is the only species commercially available in seed form. Zoysiagrass is a not a cold hardy plant. It’s the first grass variety to turn brown under cold temperatures and is slow to turn green once warmer temperatures arrive. Probably the most attractive quality of zoysiagrass is the ability to grow in virtually any soil, ranging from sandy to clay, acidic or alkaline. Moderately shaded locations are also acceptable for zoysia. Zoysiagrass is extremely drought tolerant. The plant’s root system has a great adaptation to combat drought conditions. Since the root system is very deep, it is able to maximize soil moisture potential.

Zoysiagrass is not a silver bullet for lawn problems. It encounters weed and insect problems as well. The most formidable disease of zoysiagrass is large brown patch. This disease is caused by the fungal pathogen, Rhizoctonia solani. The disease begins in small patches that turn from yellow to brown. It’s common to see these patches with healthier grass in the center. The pathogen is most active when soil temps fall between 65-75°F. This generally correlates with the fall season and then throughout the following spring in the Panhandle. Zoysiagrass is no more susceptible to the disease as any other grass, but the recovery time is lengthy. With this being said, a proactive fungicide regimen is recommended.

Zoysiagrass also responds better to smaller quantities of fertilizer applied more frequently rather than supplying larger quantities infrequently. UF/IFAS Extension recommendations state that zoysiagrass should receive three applications per year in the Panhandle region.

If you are looking to seed or sod your landscape, zoysiagrass may be an option to consider. Best management practices influence the overall health and quality of your lawn and reduces its susceptibility to disease. Take these practices into consideration when deciding on a lawn grass.

New Fertilizer Applicator Law in Effect, Training Offered

New Fertilizer Applicator Law in Effect, Training Offered

GIBMP2In 2014, a new law took effect requiring all commercial fertilizer applicators (for hire) to have a license. This law was passed in 2009 and took effect on January 1 of this year. A requirement that must be completed to obtain this license is to successfully complete a Green Industries Best Management Practices (GI-BMP) training class. One option to fulfill this requirement is to enroll in a GI-BMP class at the local county extension office. This training is provided by UF IFAS extension at various extension offices across Florida in both English and Spanish.

These classes instruct green industry professionals in techniques of fertilizer, pesticide and irrigation application that help reduce and prevent pollution caused by runoff and leaching. Runoff and leaching is usually driven by rainfall and creates non-point source pollution.  By learning how to implement the safest methods of fertilizer and pesticide application into their daily work, green industry professionals can do their part in the effort to maintain and improve Florida’s water quality and environment.

After receiving a certificate of completion, a person must pay $25 and apply to receive a limited certification for urban landscape commercial fertilizer application.  A person possessing such a certification is not subject to additional local testing.  The certification expires 4 years after the date of issuance and needs to be renewed at that time.  Florida City and County employees that apply fertilizer as part of their job duties do not need to obtain the license to be in compliance with the new fertilizer rule, but they must complete the training and obtain a certificate of completion from the GI-BMP program.

[important]The Next GI-BMP class will be held Tuesday, March 11 at the UF IFAS Washington County Extension Office in Chipley Florida. This office is located at 1424 Jackson Ave (also US HWY 90) Suite A.  It begins at 8am central time in the East Wing conference room. To register, contact Matthew Orwat or Cynthia Jackley at 850-638-6180 or mjorwat@ufl.edu Cost is $20.00 and lunch is provided.[/important]

The GI-BMP program has FDACS approval for 2 Core CEUs and 2 additional CEUs for the following licenses:

  • Private Applicator – Agriculture
  • Ornamental & Turf
  • Limited Lawn & Ornamental
  • Limited Landscape Maintenance
  • Commercial Lawn and Ornamental
  • Limited Commercial Fertilizer Applicators
  • (2) Limited Urban Fertilizer credit hours
