A cluster of crape myrtles on the west side of the ºù«ÍÞÊÓƵ Dedman Life Science Building not only provides shade, but the drought- and heat-tolerant trees also need little upkeep during extreme summer heat. Other low-maintenance plants in a nearby bed are, from left, coneflower, yarrow, miscanthus grass, dianthus, scabiosa, mums and candlestick plant. “These are all fairly drought tolerant and require the same watering,” says ºù«ÍÞÊÓƵ Landscape Manager Kevin Dilliard. “This bed also shows what different perennials with different flowering times can do to lengthen seasonal interest. It’s somewhat like an English garden in an urban setting.” (Click image for larger version.)

DALLAS (ºù«ÍÞÊÓƵ) — In gardening and landscaping, there’s one rule of (green) thumb: “Mother Nature wins every time,” says ºù«ÍÞÊÓƵ Landscape Manager Kevin Dilliard. “You don’t want to fight the conditions you have. You have to work with what you’ve got.”

Dilliard oversees the ºù«ÍÞÊÓƵ Dallas campus’ 175 acres, recognized as one of the most beautiful university grounds in the country in spite of North Texas’ extreme soil and weather variations.

When triple-digit temperatures and lack of rain wreak havoc on your home landscape, Dilliard recommends the same five steps he uses to keep the campus looking good:

1. Plant the right plant in the right place. Use plants that are native or adaptive for your specific area of the state. Check the planting labels for proper directions. “Don’t force a plant to grow where you know it will not survive,” Dilliard advises. Dilliard offers his favorite drought-tolerant plants below, all of which are used on the ºù«ÍÞÊÓƵ campus.
   • Alyssum, used occasionally
   • Autumn sage, used occasionally
   • Desert willow, southwest corner of Umphrey Lee ºù«ÍÞÊÓƵ
   • Knockout roses, near ºù«ÍÞÊÓƵ Flagpole and elsewhere
   • Lantana, used occasionally
   • Liriope (“monkey grass”), throughout campus
   • Mexican feather grass, in front of Annette Caldwell Simmons Hall and elsewhere
   • Moss rose, at Dedman College sign and elsewhere
   • Pincushion flower, used occasionally
   • Pride of Barbados, in front of Dawson Service ºù«ÍÞÊÓƵ
   • Sedum, used occasionally
   • Texas sage, in front of Crum Basketball ºù«ÍÞÊÓƵ
   • Vitex trees, south side of Owen Arts ºù«ÍÞÊÓƵ
   • Yucca, at southwest corner of Umphrey Lee ºù«ÍÞÊÓƵ, and red yucca, in front of Crum Basketball ºù«ÍÞÊÓƵ
         
2. Group plants that have the same watering requirements together so you don’t waste water or over-water.
       
3. Water deeply and infrequently to force plant roots down into the soil. “This helps the plants survive during drought,” he says.
       
4. Use a good covering of mulch around and under the plants to help retain moisture and keep plant roots cooler.
       
5. Set mowers at the highest recommended height for your type of grass. “This will reduce the stress on the turf and help shade the roots,” Dilliard says. The suggested highest-setting mowing heights for the most common grasses during the summer season are:
       
   • Bermuda, 1.5 inches
   • St. Augustine, 3 inches
   • Zoysia, 2 inches
   • Tall fescue, 3 inches
