Overview

Double impatiens are popular for their attractive double flowers that resemble miniature roses. They perform best in containers rather than flower beds and can grow from 6 to 24 inches in height, depending on the variety. The most commonly planted varieties of double impatiens include the Confection series, which have a more compact growth habit than other varieties, and the Rosette series, which are also known as rosebud impatiens. Regardless of type, double impatiens have similar care requirements. They are easy-to-grow annuals that need only minimal maintenance to thrive throughout the growing season.

Step 1

Transplant double impatiens into the garden in late May. Choose a site that receives direct morning sunlight and partial afternoon shade. Spread a 2-inch layer of manure over the planting location and use a garden tiller to incorporate it into the soil to increase fertility.

Step 2

Spread a 1-inch layer of mulch over the soil surrounding double impatiens to insulate the roots and deter the growth of weeds. Begin the mulch about 3 inches from the base of the plant to allow room for growth.

Step 3

Water double impatiens twice per week during spring, summer and fall to prevent the soil from drying out completely. Do not splash any water onto the foliage of double impatiens while watering, as moist leaves are more susceptible to fungal infestations.

Step 4

Feed double impatiens using a balanced 10-10-10 NPK fertilizer once every three weeks beginning one month after planting. Read the manufacturer's instructions for proper application and dosage of fertilizer.

Step 5

Remove the blossoms of double impatiens as soon as they wilt or die to promote additional flowering later in the season. Cut off the flowers as close to their point of origin as possible to minimize damage. Use your fingers or snip off the spent blooms with scissors.

Tips and Warnings

  • Reduce the frequency of fertilization if flowers production is low, as excess nitrogen reduces blooming.
