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 February

  • Continue planting winter annuals such as pansies, dianthus, snapdragons and chard on warmer days.
  • Sow your seeds for spring annuals and veggies, inside, per instructions based on the last frost date for your area. Remember they need full sun and temperatures around 65 to 70 degrees (watch out for those cold window sills!).
  • Don’t forget to divide and replant your summer and fall blooming perennials while they are still dormant.
  • Now is an excellent time to plant or relocate native and cold hardy trees and shrubs while they are dormant. It is also the perfect time to perform any tree trimming.
  • Get ready to start pruning your roses. A good rule of thumb to help remember this is to prune them around Valentine’s Day. Don’t forget that your climbing roses won’t need any trimming until after they bloom in spring.
  • Get mulch into your flower beds before the weather warms up and weeds really begin to sprout.
  • Don’t forget to fertilize your winter annuals throughout the winter and continue into spring. Use a complete, water soluble fertilizer to help them get established while it’s still cold.

Garden Tips for March

  • Plant cool season annuals for quick color in the garden and to replace any annuals that may not have made it through the cold.
  • 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.

Garden Tips for 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 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.
