Overview

Perennial plants benefit the gardener by reappearing year after year. Perennials provide interesting foliage and predictable bloom times. Plant predictability allows gardeners to choose a variety of plants to produce continual blooms in the home garden. Some perennial plants will rebloom in a single season with timely pruning to encourage the plant to expend energy in bud production instead of seeding.

Step 1

Provide the healthiest possible environment for the perennial plant. Allow space for the plant to mature and experience plenty of air circulation with 8 to 12 inches between plants.

Step 2

Water regularly to promote evenly moist soil. Direct water at the soil around the base of the plant to reach the root system. Drought and neglect stress perennial plants and diminish blooms. Restoring a stressed plant limits the option of a single blooming session. Reblooming isn't possible if plant health doesn't promote a healthy initial flowering period.

Step 3

Address the organic content of the soil by lightly cultivating around the plant with a wheel cultivator or hoe. Mix peat moss or compost into the soil to increase organic matter. A healthy base creates the best opportunity for a plant to thrive in the garden environment. Apply a 2- to 3-inch mulch layer around the plant to retain water and reduce weed competition.

Step 4

Thin the plant six to eight weeks before blooming time. Thinning involves the removal of evenly spaced stems to open up the interior of the plant. Thin lightly by clipping evenly spaced stems throughout the plant. Make angled cuts close to the main plant stem or nearest a larger branch.

Step 5

Monitor the plant continually during the normal blooming period. Clip off dead blooms directly behind the flower head to induce the production of more buds. Deadheading extends blooming time and increases the groomed look of a perennial plant. This practice also discourages the plant from expending energy in the production of seeds on spent flowers. Conserving plant energy allows for a potential rebloom in the same season.

Step 6

Apply all-purpose fertilizer monthly during the growing season.
