Landscaping: Tips for the Heat

The hot Texas sun can do a number on your landscaping if you don’t protect it by watering properly and choosing the best shrubs and flowers to withstand the heat.

Watering your lawn and flower beds is best done in the early morning hours – between 5 and 9am. This allows ample time for the water to soak into the soil before the hot sun causes it to evaporate. Also, you don’t want your grass and plants to be damp for long periods of time (i.e. overnight) as this can let fungus and disease creep in.

Set your irrigation system or turn on your sprinklers and time how long it takes for one inch of water to accumulate. You can do this by setting out an empty can and measuring how full it is after you water. You should water your grass twice per week, a half inch of water each time. This infrequent, deep watering will promote healthy root growth. Flower beds may require more frequent watering to keep plants perky – just set your irrigation system to only water the beds and not the grass on off days.

The best flowering plants that can withstand the heat, sun, and dry conditions are the African Daisy, Butter Daisy and Fanflower. The Dusty Miller plant, though it doesn’t make blooms, has a nice, slivery-gray color that can bring a garden together. Dakota Gold is another profusely blooming plant that can take up to 100 degree heat with little watering, as can Lantana (which also makes an excellent ground covering).

Scope out how much sun your flower beds actually get. If an area is shaded for part the day, some of these plants may do better: Dahlia, Impatients or Begonia.

Keeping your flowerbeds and gardens well-mulched will keep the moisture from watering in the soil and help the plant’s root system. Placing organic matter in your soil before planting will also help retain moisture as well as provide nourishment.
