Mushrooms in the Lawn

After a long, hot, dry summer that had homeowners watering weekly to keep their landscapes green and growing, the recent rains have provided a welcome reprieve from the task. When the weather cooperates, lawns stay green on their own!

However, when the lawn starts sporting mushroom caps and other unusual fungal growths as an additional effect of that rain, homeowners, especially those with pets and small children, might become concerned.

The UGA publication Recent rains have mushrooms popping up in Georgia lawns, by William Tyson and Tripp Williams, describes several mushroom types that commonly appear after the first rains following a dry spell. Most of these are not harmful to the lawn, but they can mar the expanse of green that a homeowner has worked hard to achieve, and they can be harmful to children and pets who might try to eat them.

Individual mushrooms can be hand-picked from the lawn, and the dog-vomit slime mold (its name pretty much describes its appearance) can be dispersed with a blast from the hose.

The UGA publication provides helpful information for management to reduce the incidence of these fungi in lawns:
"The best way to keep mushrooms out of your landscape is to irrigate before the lawn gets too dry. If it stays somewhat moist, the fungus will stay underground and will not produce mushrooms. The lawns that tend to be covered with the most mushrooms are those that never get watered during droughts.
"To rid your lawn of mushrooms, pull them up, kick them over or run over them with the lawn mower. This will keep them from releasing the spores that spread the fungi. Aerate your lawn to prevent further damage to your turfgrass.

"After aerating the soil, water the area to dilute any toxins and wash them through the soil profile. If a patch of grass is dead, re-establish that area next spring, and keep it moist to prevent new mushroom growth."

Now is a Good Time for Kudzu Bug-Proofing Your Home

As the weather cools, kudzu bugs will be leaving their summer hangouts in kudzu, wisteria, pole beans, and soybean-fields and will be looking for a place to stay for the winter.

Unfortunately for many homeowners, these small, grayish-brown bugs have the same, annoying knack as ladybugs for finding their way into houses as favored places to escape the cold. Keeping the pests out may require some work, which should start in advance of cooler weather.

According to a UGA report on kudzu bugs, Megacopta cribraria as a Nuisance Pest, by Daniel Suiter, Lisa  Ames, Joe Eger, Jr., and Wayne Gardner, the pests were first found in the U.S. in Georgia in 2009. They had been seen in large numbers on the outsides of houses in October of that year in nine Georgia counties. Since then, they have spread across the Southeast and aggravated a lot of farmers, gardeners, and homeowners.

The report offers these suggestions for defending a home from invasion by these pests:

"...homeowners should ensure that screening is placed over possible routes of insect entry into the house; that screens on windows are well-seated and without holes; and that soffit, ridge, and gable vents are properly screened. In locations where screening cannot be used, such as around pipe penetrations, steel wool can be stuffed into these openings to prevent the entry of M. cribraria. Lastly, doors should establish a tight seal when closed, and doorsweeps should be installed."

The report also cautions against crushing any kudzu bugs that are found indoors, since "...this action may stain indoor surfaces and/or result in odors that may prove difficult to eliminate. Rather, insects should be vacuumed and the bagged insects then placed in hot, soapy water."

Sales Tax Holiday for WaterSense Products

October 5-7 is a good time to commit to saving water in Georgia. That’s because purchases of WaterSense-labeled products will be exempt from state and local sales taxes.

WaterSense-labeled toilets, showerheads, faucets, irrigation controllers and other products use at least 20 percent less water, and perform as well as or better than conventional models. Independent, third parties certify that WaterSense-labeled products meet U.S. E.P.A. criteria for water efficiency.

Replacing a standard showerhead with a WaterSense-labeled one can save thousands of gallons of water a year. Replacing an old toilet with a water-efficient one will save more than two gallons a flush. Besides saving money on the sales tax, residents who purchase a WaterSense-labeled toilet may qualify for a rebate.

Details about which utilities offer rebates, either directly or through the Metro Water District are available at www.northgeorgiawater.org/toiletrebate.

The sales tax holiday on WaterSense-labeled products will start Friday, October 5 at 12:01 a.m. and will continue through the weekend until 11:59 p.m. on Sunday, October 7.

WaterSense-labeled products with a sales price of $1,500 or less purchased for noncommercial home or personal use during the sales tax holiday will be Georgia state and local sales tax-free.
