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 fall.


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 May

  • Plant your heat tolerant summer annuals and tropicals, if you haven’t already. Our favorites for the heat are Lantana, Ornamental Sweet Potato Vine, Purple Fountain Grass, Ornamental Peppers, Coleus, Elephant Ears, Caladiums, Pentas, and Tropical Hibiscus.
  • Continue planting perennials, trees and shrubs. Just be sure to water them in well as the temperature rises and continue watering them regularly, making sure to saturate the root ball on trees and shrubs as much as twice per week, throughout the summer.
  • The last of the heat tolerant veggies and annual herbs can be planted until mid month, including Southern Peas, Sweet Potatoes, Basil and Oregano.
  • Fertilize your lawn and garden with a high nitrogen fertilizer, following recommended application rates.
  • Be sure to water grass regularly during the hot summer months, up to one inch depth, 2 to 3 times weekly, or what your city water restrictions will allow.
  • Mow your lawn once per week to maintain good healthy growth and reduce any unnecessary wear and tear on lawn equipment.
  • Continue pruning and reshaping any spring blooming shrubs and vines after they finish flowering.

Garden Tips for June

  • Plant summer annuals and tropicals. Don’t forget to water them in 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.
