Back to School and Back to the Yard


Horticulture Hotline 08/12/19
By Bill Lamson-Scribner

Army worms, mosquitoes, gray leaf spot, chinch bugs, nutrient deficiencies, weeds, heat, vines, fire ants, lace bugs, rats, flies, fleas, termites and roaches seem to be dominating the question counters at the three Possum’s.

Army worms will affect the aesthetic value of the green grass on athletic fields, golf courses, and home lawns, and the worms thin the canopy of the grass Prostrate growing weeds like spurge, lespedeza and Virginia Buttonweed seem to come in the fastest.

What bothers me the most is you work all summer on your grass to have it looking nice, and once it starts to slow down for the winter, fall army worms and then sod webworms attack the grass. Look for areas that appeared to have been mowed low and with a dull blade. You can see that the leaf blades have been chewed. Also thatch type debris will be churned up on the surface. Birds and low flying wasps are also predators of army worms.

Since army worms are in direct contact with the ground, they are very easy to control. Bug Blaster, Bifen, Sevin, Cyonara and Acephate will all put a hurting on army worms. Thuricide (Bt), EcoVia EC and Spinosad are organic products that will also work well if you get them while the worms are small. Since the population of worms is so high and hit so hard, keep your eye out for a second hatching.

For those of you with St. Augustine and Centipede, keep your eye out for the sod web worm. Watch for moths in your yard around dusk. If you begin to see a moth that gets out of the grass, flies for 6-10 feet then lands again (like a bobwhite quail for you bird hunters) you may want to consider using one of the above mentioned products. Usually sod web worms would not come out until September / October; however, with the crazy weather we are having, scouting for them could not hurt.

Now is the time to put out preemerge products in the lawn and beds to prevent those small seeded annual weeds. Henbit, chickweed, Poa annua (annual bluegrass), cudweed and lawn burweed are a few of the winter weeds that would like to occupy your lawn and flower beds. Poa annua (the green grass that is very visible in February and March) and lawn burweed (the prostrate growing weed that develops a sticker) are usually the most hated of the winter weeds. Some people use profanity while describing them at the counter of Possum’s! 

If your yard has thatch, drainage, or compaction issues, now is a great time to aerate your lawn (and beds where possible) before you apply your fall preemerge. Aeration is a great cultural practice, which will among other things help your roots grow throughout the winter giving you a head start for the spring.  
 
The “nasty rascal the chinch bug” is still sucking the life out of many lawns. Gray leaf spot is still alive and doing well. With the rain, fire ants are mounding up everywhere – be careful where you step! Mosquitoes are out and biting especially in the evening. Flies are causing restaurants’ ratings to drop.

Mower Maintenance Mid Season


Horticulture Hotline 08/05/19
By Bill Lamson-Scribner

The summer is going by in record speed. The football, volleyball, fall soccer and deer seasons are right around the corner. Soon we will be enjoying cooler weather! Soon your grass will not need mowing every 5 days! For now we are fighting army worms, chinch bugs, mosquitoes, fire ants, lace bugs, mice, rats, and many other Lowcountry critters. Love the Possum! 

There are still some things to take care of this summer. Try to find a source of gas for your lawn mower that does not contain ethanol. Use ethanol free gas in your small engines, boat motors, and generators (have you tested your generator recently?). Your mower will be happier next spring if you use ethanol free gas.

The mower blade needs to be inspected this time of year. Always remove the spark plug wire from the plug and tape it to the side of the mower to avoid accidently starting the mower when you turn the blade to inspect it (or remove the plug). The mower blade works like an old time airplane propeller if you spin the blade it will start the engine.

In the old days, we use to sharpen our mower blades ourselves. Now days, there is a lot of aerodynamics and engineering that goes into these blades, so you are better off buying a new blade. Be sure to buy a replacement that is suited for your mower. These blades move at high speeds, so be sure they are balanced correctly like the tires on your car.

You want a nice sharp blade that has not run over pine cones, small sticks, gum balls, the hose, or any other foreign object. A nice sharp blade will give your lawn a better cut (look) and the leaf blade will have less entry points for disease.

While you are checking out your mower, how clean is the air filter? If your air filter is not clean, a lawn mower can produce some nasty air pollution. Mowers do not have all the emission controls that our cars have, so a clean air filter is really important. I guess a dirty air filter would be like your mower having an asthma attack – the engine needs good air flow.

The other main thing to check would be the engine oil. When was the last time it was changed? Have you mowed enough hours that it is time to change?

If this sounds like a Saturday morning of fun, have at it. If not, take it to your local small engine repair shop!

Localized Weather


Horticulture Hotline 07/22/19
By Bill Lamson-Scribner

Mosquitoes, roaches, fleas, flies, chinch bugs, army worms, wasps, spiders, spittlebugs, and mice have become much more visible with the hot weather. Localized pop up thunder storms (gray leaf spot) have dominated our weather, so there is no telling how much rain we are getting across the area as a whole.

With three Possum stores in the area, I get a regular dose of how crazy our weather is in the Lowcountry. Possum’s West (West Ashley) might get an inch of rain, Possum’s North (North Charleston) might get a “spit” and Possum’s East (Mt. Pleasant) nothing at all. It is amazing how the waterways affect the weather patterns.

The Lowcountry is one area that a rain gauge is a must. Rain gauges come in all shapes and sizes. Some are very expensive and record your rainfall, and others are very basic and are less than five dollars. You can make your own “rain gauge” very easily from anything that has an equal top diameter and bottom diameter. Soup cans, tuna fish cans, a coffee cup, or an empty can of canned possum (the other white meat) make great rain gauges. Be sure to place your rain gauge in an area where your house or trees are not going to skew your results.

Over the weekend, I was surveying the yard for potential mosquito breeding sites. We have this roll around basketball hoop in the driveway that requires water in the base to stabilize it. Of course someone lost the cap to the place you add water and now there is a great place for mosquitoes to breed. The slightest dent on my trash can lid also collects water where there were mosquito larva. I keep 3 sizes of measuring cups on a window sill near the hose where I mix up my “solutions” for killing weeds, fungus, and insects around the house. Rainwater had got in them, and you guessed it – more mosquito larvae. Tarp on my boat, magnolia leaves, five gallon bucket (s) ...Oh yeah, the rain gauge had mosquito larvae in it as well. Always empty out your rain gauge!

With all the insects that are active in the yard Cyonara Lawn and Garden Concentrate or RTS is an excellent product with a very broad label and a low price point. Cyonara is labeled to spray the outside of your house to keep roaches in check and even your vegetable garden, so you know it is safe. If you prefer organic products, EcoVia might be more to your liking.
