Gardening Tips

Need help planting a successful garden? These tips and tricks from our horticulture staff can help keep your home garden looking beautiful this spring.


In North Texas we ask a lot of our plants. With extreme temperatures in the summer and periods of too much or no rain at all, it's important to equip your garden accordingly. Take a look at these suggestions designed to help your home garden thrive.

Garden Tips for June

  • Plant summer annuals and tropicals. Don’t forget to water them after planting and keep them watered regularly during the summer heat.
  • Begin cutting back any overgrown perennials and annuals to keep growth compact.
  • Continue mowing your lawn once per week to maintain good healthy growth and reduce any unnecessary wear and tear on lawn equipment.
  • Continue fertilizing your lawn and garden with a high nitrogen fertilizer, following recommended application rates.

Garden Tips for July

  • July is the month to start your fall tomato garden.
  • Begin trimming spent flower stalks on perennials.
  • If you haven’t done so already, cut back some overgrown annuals (such as impatiens and coleus) and perennials (such as asters and salvia). A light shearing can help prevent the plants from falling over.
  • Roses can be trimmed back now by one-third to one-half so they will rejuvenate for the fall season.
  • Mature or overgrown climbing roses can be shaped up now without damaging next year’s bloom potential.
  • As it continues to heat up outside, keep your plants well watered.
  • Continue mowing your lawn once per week to maintain good healthy growth and reduce any unnecessary wear and tear on lawn equipment.
  • Continue fertilizing your lawn and garden with a high nitrogen fertilizer, following recommended application rates.

Garden Tips for August

  • Proper watering is crucial in August. Apply one to two inches of water per week to landscaping.
  • Keep an eye out for webworms in trees. Use a garden hose to blast them out of the trees with water or cut them out with pole pruners.
  • Plant vegetable crops, including corn, tomatoes and beans for fall harvest.
  • Plant seasonal annuals such as marigolds and ornamental peppers for fall interest.
