How to Plant Ornamental Plants

Although every plant has its own likes and dislikes, most ornamental plants will benefit from being planted in fertile soil that drains well and gets the right amount of sun for that variety. Container-grown plants, meanwhile, need a pot that will allow their roots room to grow without being so big that the plant looks lost in it. Most plants benefit from about an inch of water a week, either from rain or supplemental watering, especially when they are newly planted. Mulching with an organic material like bark chips is another good practice that helps protect the root zone and keeps your plant from drying out.

How to Grow Ornamental Plants

  • When. Perennials can be planted in spring after the ground has thawed or early fall before your first frost. Bulbs are best planted in fall. Container-grown plants can be planted at any time, but expect less growth if you plant them during the winter months.
  • Where. Read your seedling’s plant tag to find out how much sun it needs. Also note how big the mature plant will get, and allow enough room around each plant so that it can grow without smothering other plants. Most plants grow best in soil that drains well and is not prone to standing water after a rain.
  • How. Dig a hole that’s as deep as the seedling’s root ball and twice as wide. Plant the plant in the hole and fill in around it with soil that’s been mixed with well-rotted compost or manure. Tamp down soil and water thoroughly.

How to Care for Ornamental Plants

  • Watering and nutrients. Water newly-planted seedlings every few days until you see signs of robust growth. At that point, you need only water when the ground is dry. Feed your ornamental plants with a balanced, slow-release fertilizer designed for landscape plants in spring and as indicated throughout the summer, tapering off by early August.
  • Pruning. Prune out dead, diseased, or broken branches or stems on your ornamental plants. Some may also benefit from deadheading — removing spent blossoms, to encourage more flowers.
  • Pollination. Since you are not growing ornamentals for fruit or berries, pollination isn’t as important. You may be pleasantly surprised, however, to see that your ornamental plants draw pollinators such as honeybees, hummingbirds, and butterflies.
