Dealing with Drought

No Showers, No Flowers

Drought conditions can cause extreme stress to your exterior landscape. Numerous municipalities were affected last year by drought conditions and each city or county has become much more vigilant in enforcing watering codes and restrictions. Even properties with irrigation systems can suffer the effects of drought via insufficient saturation or municipality regulated usage. In addition to plant damage or loss, stressful conditions can play host to a myriad of ornamental pest and disease problems.

The Effects of Drought
Cool season turf types like Fescue or Bluegrass are very susceptible to drought conditions. As this type of turf undergoes drought stress it will become brittle and yellowed in color. This happens as the turf enters a period of dormancy as a natural defense against lack of water. Most turf stands that enter dormancy will recover with watering, however, extreme conditions can result in the loss of lawn areas. Whereas warm season turf types will fare a bit better, Centipede turfs will likely not survive a drought. Shrubs and trees will experience die back of leaves and branches and eventually die if not given adequate water.

So what do we do when water is limited and rain is nowhere in the forecast? We ask our Exterior Service Management Company to suggest how we can help lawns stay green through a period of limited watering. Here is some pertinent information that will assist you and the maintenance your store exteriors through a damaging drought.

Treating Drought Symptoms
There are several steps that can be taken to ensure minimal damage from drought and, in fact, increase survivability of the turf areas affected. First and foremost is to adjust mowing heights. Cool season turf varieties should not be mowed to a height less than three and a half inches. Warm season turfs, such as fairway Bermuda or Zoysia’s, should not be mowed to a height less than two and a half inches. Additionally, fertilizer programs should be temporarily postponed as they can cause more damage than good. In any event where a plant is stressed, and a blade of grass is a plant, feeding is counterproductive to growth and maintenance of health. Nutrients will not be absorbed and will likely leach resulting in a waste of budget dollars. However, programs that combine selective herbicides such as Trimec or Balan with the fertilizer must still be maintained to inhibit weed growth. Separate applications should be made and the fertilizer should be avoided until temperatures cool and rains return.

For many species, fall is the best time to plant. This usually allows enough time for plants to become well-established before cooler, wetter weather sets in and provides additional root growth the next spring. Once established, many drought tolerant plants can survive on just the water they receive from normal rainfall. It is important to remember, though, that even drought-tolerant plants, shrubs and trees may occasionally need some additional water, so it is important to learn to recognize signs of heat and water stress. Besides obvious signs of wilting, plants give off other distress signals like dull foliage, premature dropping of leaves and poor flower production.

Drought Tolerant Plants
A professional Exterior Services Management Company can educate you on various drought tolerant plants, flowers, shrubs and trees that are genetically engineered to grow well in regions that get little or infrequent rainfall. These plants require less water and tend to be more pest and disease resistant.

Picking the Right Plants
A professional ESM company can make numerous recommendations toward ensuring that you have a water wise exterior that still provides curb appeal. There are hundreds of drought tolerant plants that can add beauty to the landscape and survive periods of drought. If you have facilities or stores in a region of the United States that is prone to drought, consult your ESM Company to develop recommendations regarding plantings, as well as, adjustments to irrigation use. Many municipalities offer incentive programs and rebates for locations that actively pursue xeriscaping and water wise landscapes.

Drought Tolerant is Safe and Beautiful
Just because they are drought tolerant doesn’t mean they are drab and ugly. With careful consideration; you can find drought tolerant plants that flower with beautiful yellows, reds, purples, blues, pinks and brilliant whites. Many commercial suppliers sell native wild flowers that contain drought tolerant plants that can add vibrant color to your store or facility exteriors. You can also integrate many non-native species of drought tolerant flowers that cover every color of the rainbow.

Save Water & Money
By utilizing drought tolerant plants, you not only reduce your water bill, but you can reduce maintenance costs. By focusing on plants that prefer dry weather and soils, you reduce the expense of replacing less-hearty plants.

Water Conservation Tips

  • Always check for leaks in pipes, hoses, faucets, and couplings. Even the smallest drip can waste 20 or more gallons per day.
  • Inspect your irrigation system for leaks and broken heads and repair as soon as possible.
  • Use water from dehumidifiers to water indoor and outdoor plants.
  • Collect condensation from air conditioning units to use for watering plants.
  • Buckets placed under gutter downspouts can collect rainwater for plants or cleaning projects.
  • Make sure you know where your water shut-off valve is located. This could save hundreds of gallons of water and damage to store if a pipe were to burst.
  • Consider using drought tolerant plants, shrubs and trees.
  • Encourage management, employees and contractors to be a part of a water-conscious community.
