March Landscape & Gardening Tips & to-Dos

Need help planting a successful garden or landscape? Here are some March planting tips from the Dallas Arboretum horticulture staff and the Dallas County Master Gardeners that can help keep your home garden looking beautiful this winter, whilst having it ready and set up for success in Spring! Plant care should be your focus in 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.
