Turf Report

Here at Lawn Tech, we work hard to give our customers the best lawn care experience as possible.  In addition to providing exceptional service, we strive to educate our customers on ways they can keep their lawn healthy and green all season long. Check out our seasonal tips below to learn how you can maintain your turf!

We are applying Surface Feeding Insect Control.  This application will help control surface feeding insects such as chinchbugs.  Chinchbugs feed on the grass plant chewing it down to stubs.  The damage mimics drought stress.  This application also targets ticks and fleas.​

What's Happening Now 

Lawn Disease Alert:

Red Thread, Dollar Spot, and Leaf Spot are prevalent in lawns due to the amount of rain we have been getting.  These diseases are most easily seen right after mowing as pink/red (red thread), white/brown patches that appears like "cob webs" in the early morning (dollar spot).  These diseases usually do not cause permanent long-term damage.  However, if the weather pattern continues on the same path as last year and the disease looks to be spreading, we recommend applying a fungicide to stop the diseases from spreading for up to 3 weeks.   (see below for description of Ascochyta leaf blight disease)

    

 

Ascochyta (As-co-key-ta) leaf blight is unfortunately beginning to appear in lawns in our service area.  It is a fungus that causes a rapid straw to bleached appearance of the grass, primarily on Kentucky bluegrass (also effects to a lesser extent: perennial ryegrass and tall fescue).  The damaged turf areas seem to occur very quickly; one day the grass appears fine and the next there is bleached tan appearance.  Most noticeably where the mower tires tracks are (any traffic on the turf areas can cause the damage to happen).  

The fungus likes to grow during wet conditions favored by prolonged periods of foliar moisture (rain, irrigation, dew, humidity).  Infectious spores are everywhere throughout the lawn and with a sudden increase in hot temperatures they rapidly infect the stressed grass.  Tire tracks show up because the tires cause just enough abrasion stress for the fungus to enter the plant tissue. Look for bleached leaf tips that are collapsed. This disease usually does not affect the crown of the grass plant, so it should recover on its own.  The damage at first appears very dramatic.  The good news is most of the damage is on the leaves, while the crowns and roots of the plant are not damaged.  It usually does not cause long term permanent damage and fungicides are not required.

Ascochyta leaf blight symptoms can develop throughout the growing season but are more common during hot, drought periods that were preceded by cool, rainy conditions (late spring transitioning into summer).  Ascochyta leaf blight usually occurs in full sun areas and it stops where the shaded lawn has less heat stress.  Raise the mowing height, mow less frequently and use a “sharp blade” to avoid excessive leaf shredding. This will reduce your chance of experiencing mower track incidence.  

  

Mowing: Do not mow when the grass is wet or during the hottest part of the day or with dull mower blades.  Weather and mowing contribute to DISEASE......such as red thread, leaf spot and dollar spot.  Disease organisms spread easily in fresh cut grass, and the newly cut blades offer an opening for infection.  Lawns are mowed approximately 30 times during the season.  What that means is, the grass plant is cut/injured at least 30 times, making it susceptible to disease each time.    

 

Nutsedge:  Yellow nutsedge is a warm season perennial plant.  The shallow root system produces many nut-like tubers, which are underground food storage organs.  Each of these tubers can germinate and produce new plants. Each new plant can also produce rhizomes which can give rise to additional new plants.  During the summer, germination of tubers and seed produced by plants from previous years are capable of producing new yellow nutsedge plants. Because of the seed and tubers that remain in the soil, repeat infestations in subsequent years should be anticipated.  

Unlike most lawn weeds, yellow nutsedge is not controlled with applications of traditional annual grassy weed or broadleaf weed control products.  This "weed" is a member of the sedge family and requires the use of very specific herbicides to achieve satisfactory control.  A nutsedge spray will only kill nutsedge that is up at the time of the application. That is why we recommend waiting until most of the nutsedge has germinated before a control product is applied.

 

The window to perform aeration and overseeding is short and the schedule will fill up fast.  In addition, for proper seed germination, aeration with overseeding takes priority and is scheduled as follows:

Core aerations with overseeding will be scheduled: August 26th - October 5th (Soil testing required for us to seed.  Dates are weather permitting).
Core aerations only will be scheduled: October 6th through the beginning of November (weather permitting).
