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.


March

  • Plant cool season annuals for quick color in the garden.
  • Some warm season veggies, such as tomatoes, can be planted late in March, but be prepared to cover them if we have freeze or frost.
  • You may still have some time to dig and divide fall blooming perennials if they haven’t started putting out new growth yet.
  • It’s a great time to plant new trees and shrubs in the garden so they establish a good root system before summer. Make sure to fertilize them so they get a good start.
  • Begin thinking about sodding or seeding your lawn late in March once the last frost date has passed. Mow your lawn shorter than normal to help remove early weeds before seeding. Grass is an easy-to-maintain groundcover that helps retain soil moisture and helps reduce soil erosion. Don’t forget to start fertilizing your lawn as well.
  • Prune and shape any spring flowering shrubs and vines as soon as they finish blooming.
  • Once trees and shrubs begin to green up, trim any dead or damaged areas that become obvious.
  • Continue Fertilizing winter and spring annuals.

April

  • Begin planting summer annuals, such as lantana and pentas (sun) and impatiens and coleus (shade), as they become available at local nurseries. Some summer tropicals may also be found in nurseries toward the end of April.
  • Now is a great time to plant new perennials in your garden. Make sure to select plants that are right for your zone. Consult nursery professionals if you are uncertain.
  • Continue planting new trees, shrubs and roses. Don’t forget to fertilize new plantings.
  • All summer veggies and herbs can be planted this month.
  • Continue sodding and seeding lawns. As the temperatures warm, make sure sod stays moist until it begins to root out.
  • Continue any tree and shrub pruning to reshape old and new growth.
  • Continue pruning and reshaping any spring blooming shrubs and vines after they finish flowering.
  • Continue fertilizing lawns and prepare to start mowing if you haven’t already.

May

  • Plant your heat tolerant summer annuals and tropicals, if you haven’t already. Our favorites for the heat are Sunpatiens, Lantana, Ornamental Sweet Potato Vine, Purple Fountain Grass, Ornamental Peppers, Coleus, Elephant Ears, Caladiums, Pentas, Tropical Hibiscus and Bougainvillea.
  • Continue planting perennials, trees and shrubs. Just be sure to water them in well as the temperature rises. 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, two to three 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.
