Summer is turf disease season for cool season and warm season grasses. Brown patch fungus on Fescue started in early May this year. We have seen sporadic cases of Pythium and Dollar Spot on warm season turf. Brown Patch Fungus activity has been high on Fescue at the end of June due to the high humidity and thunderstorms. It is always better to control diseases preventively vs. curatively.
Yellow Nutsedge is a prolific and very difficult weed to control in many lawns and natural areas. Nutsedge is not a broadleaf weed or grassy weed but is in the sedge family. Yellow Nutsedge is a summer perennial that flourishes from April/May to around September/October. It reproduces from tubers (nutlets) under the soil and can spread from rhizomes. Each plant can produce hundreds of tubers during its growing season. These new tubers will be new plants in the years to come. Nutsedge will have a triangle stem and is easily felt when you twirl a stem between your thumb and forefinger. Yellow Nutsedge will grow much faster than the existing turf and will have a thin shiny appearance.
Post-emergent broadleaf weed controls for weeds like clover and dandelions will not control Nutsedge. There are limited products available for controlling Nutsedge and all of them require frequent applications over multiple years to offer acceptable control.
Heat/dry stress is often misdiagnosed as fungus or other issue. Signs of dry/heat stress include; a darker color to the lawn, visible footprints, and the leaf blade will be folded and thin looking. The grass blade appears to be almost straw like on all types of turf, including Bermuda and Zoysia. If the lawn looks ok in the morning then looks poor in late afternoon, it is probably heat/dry stress. Tall Fescue will usually go into a semi-dormant state and shut down. Most of the turf will bounce back with cooler temperatures and rain fall. It is important for the fescue to be healthy from proper fertility and a 3.5” to 4.0 mowing height before, during and after this semi-dormant state. We have about two more months of these climatic conditions.
Many people are under the impression that Warm season turf lawns like Bermuda and Zoysia cannot experience heat/dry related injury/stress during summer. However, warm season turf grasses are just more heat/dry tolerant than warm season turf. They generally recover from these stresses better than a cool season turf. Warm season and cool season turf stress is exacerbated when the turf is growing in poor conditions (i.e. shade, compact soil, etc.) and/or struggling to recover from a harsh Transitional Zone winter. Like Tall Fescue, most of the turf will bounce back if the turf was in good health.
Warm season turf is heat/dry tolerant but not exempt from experiencing the same conditions as cool season turf like Fescue during hot dry weather. Tolerance means it can tolerate those type of conditions longer and have the ability to generally recover faster.
