Kansas City is in Horticultural Drought

Agricultural droughts that impact the 3.4 billion-dollar Kansas wheat harvest will gain national media coverage globally, but when we have a drought that effects our lawns and landscapes, it can frequently be overlooked until we realize it is impacting our own homes. Right now, in Kansas City, we are on the verge of seeing damage to lawns and recently planted landscapes that have not occurred in decades according to Jerry Moore of the Grass Pad in Olathe Kansas. “I went into this business 40 plus years ago and had never seen lawns this brown in May”. “Grass looks like it normally does in August and it is still May.” According to the latest data from Eric Luebehusen, with the U.S. Department of Agriculture most of Kansas continues to be in moderate to severe drought with extreme drought in southwest Kansas.

When grass turns brown like this, it allows sunlight to get to the soil and dry it out even faster. The sun will cause our weed preventers to fail, and crabgrass and foxtail will appear earlier this year than usual. When lawns have crabgrass and foxtail epidemics that last more than the typical month of August the desirable grasses are crowded out, and the fall frost will leave the yard bare and susceptible to soil erosion over the winter.

Trees and shrubs planted in the last 3 to 5 years are at risk as well. According to the Morton Arboretum during times of drought like this, the young roots of trees and shrubs are killed outright. The soil becomes hard and compact in the top 1 to 2 feet where the roots live. Plants like trees, shrubs, groundcovers and especially evergreens without adequate watering will suffer much. Massive plant loss is likely if it does not begin to rain. Add these conditions to the increased planting Kansas City has seen recently with the current Real Estate boom these losses will add up to millions of dollars in damage and loss.

People should be diligent about watering their lawns and landscapes. The soil should be saturated at least 12 inches deep. Trees that have been planted in the last five years will not have developed a root system extensive enough to withstand a drought that could go on for six months or more.

Insects, as well as weeds, thrive in these conditions. Ants, fleas, and ticks love dry conditions and will reproduce unharmed by typical spring rainstorms that have missed us. Pets and people should be monitored closely as last weeks warm weather will trigger the hatch cycles of most all pests.

Control Broadleaf Weeds in Fall

As many of you know, there are two types of common weeds we talk about at Grass Pad. The first type is annual grassy weeds, like crabgrass, foxtail and goosegrass. These annual grassy weeds sprout from seed each spring, living only for one season and will die at the first winter freeze. Annual grassy weeds are controlled using PREVENT!, a pre-emergent, applied in early spring. Killing the weed seed as it starts to germinate in the warm soils of spring.

Post emergent control for annual grassy weeds can be done in early summer using Uncle's Q-Bomb. As fall comes around, don't worry so much about controlling an annual grassy weed that will die at first frost. Concentrate more on overseeding and fertilizing your turf following Uncle's Fall Lawn Renovation program.

The second type of weed is the broadleaf weed. These are the wide leaf weeds you will see in thin areas of the lawn blooming with white, yellow or purple flowers in early spring. Weeds like dandelion, clover and chickweed that look like they could be on the salad bar at Price Chopper. Most of these broadleaf weeds are perennial and will live through our winter here in Kansas City.

Broadleaf weed invaders are revitalized with cool weather and fall rains. Growing, spreading and filling thin and open areas in turf created from summer abuse, heavy traffic and weather. As days get shorter, Mother Nature is sending a signal to her plants; the winter is soon to come. Plants begin an energy storage phase in order to survive the long winter. It is the same for trees, bushes, perennial grasses and weeds.

Fall is an ideal time to control perennial broadleaf weeds like dandelions and clover. Perennial weed plants are busy collecting energy to store for winter survival creating a window of opportunity to apply granular Loveland Weed and Feed, liquid Speedzone or Trimec. The herbicide is quickly translocated from the leaf tissue deep into the root for maximum kill. Controlling broadleaf weeds in early fall, will open space for fall overseeding.  Furthermore, broadleaf herbicide applications made in October and November have very little chance of affecting trees and shrubs that are near dormancy. Fall fertilizing with Loveland Renovator or Golf Course Starter stimulates new seed and existing grass plants to quickly spread and fill in. No bare spots, mean no room for weeds.

Uncle's What Ifs:

• If you have already applied new seed to your lawn, avoid using herbicides until the new seed has germinated, filled in and mature enough to have been mowed at least twice. 
• If you have already applied any of these herbicide products, wait 14 days after application to broadcast new seed in to those areas. 
• If you are the procrastinator and suddenly notice it's late fall, your best choice may be to get your seed and fertilizer down first and control broadleaf weeds later.
• If you have any questions call your nearest Grass Pad or just come on down!
