Is your Zoysia grass having a problem greening up this spring?

Brown Patch 1Zoysia grass is a very durable and sustainable turf, but it has some downfalls, especially coming off our wet winter.  Some areas in your yard may not be greening up as normal and may appear dead.  This is being caused by Zoysia Brown Patch.

Zoysia Brown patch is the most damaging disease to Zoysia. Excessive moisture and high nitrogen fertility levels often lead to the outbreaks. The disease usually develops on lawns during periods of wet, overcast weather in late spring or fall.

Here are some tips on how to control problem:

  1. Moisture plays an important role in disease development. Good drainage is needed to remove excess water from low-lying areas.
  2. Use a slow-release nitrogen fertilizer that will last up to six months in the soil. This reduces the active nitrogen available to the plant and slowly feeds it consistently as it’s greening up. Unique’s Turf Grass Division has been using this type of fertilizer in our lawn applications this spring to help prevent this problem.
  3. Cutting your grass on a regular basis is also helpful in reducing thatch build-up, which acts like a moisture sponge and can help spread the disease. We also recommend cleaning your mower deck off after every use to prevent any kind of fungus growing under it that could be spread throughout the yard.
  4. Once you see a problem it is very important to get on a fungicide program to prevent the spread. This fungal disease lies dormant in the soil and sometimes never activates if proper environmental procedures are followed. But if this occurs, preventative measures to eliminate the fungus are important and reducing water is critical. Most established Zoysia turf grass only needs to be watered three times a week and prefers to dry out between watering.

Ambrosia Beetles are a serious problem in the landscape.

We have a menacing pest that has caused more damage over the last 10 years to the landscape trees than any other insect in the Atlanta area. This random and non selective pest preys on unsuspecting trees.  It lays it’s eggs on the bark and then the larvae bore into the tree.  At this point, it is certain death of the tree.

Ambrosia Beetles ComboHome owners have a few products available to them that contain the active ingredient, permethrin or bifenthrin, that may be sprayed on the trunk, such as certain Spectrum, Ortho, and Bayer Advanced products.  Examine the label for these active ingredients for some type of borer listed on the label. “Granulate Ambrosia” beetle will not specifically appear on the label. You are better off doing everything that you can to reduce the stress of the tree or shrub in hopes that the plant will outgrow the attacks. Organic products such as Pyrenone or PyGanic may be used, but are expensive and may not be available in small amounts. Their effectiveness has not been well studied.

If your trees have been infested, you can also call some of the local tree services that have certified arborists on staff and offer spray programs for protecting your trees from this problem.

Great botanical garden to visit if you’re in North Carolina!

The Sarah Duke Botanical Garden in Durham, North Carolina is on the campus of Duke University. This garden was once a rock quarry that was converted into a beautiful plant exhibit. I would definitely recommend coming in early spring and again in the fall to enjoy the seasons of color and the many unique plants that offer a beautiful rolling landscape.

With terrace gardens, woodland paths, Japanese gardens, educational areas and other information, this easily takes a full day to experience.  Seeing mature plants in their natural setting is inspiring when designing or just enjoying what nature has to offer.

I also highly recommend taking the time to go to Duke Chapel. With its stained-glass and architectural features, it’s worth a stop.
