How to Prune Impatiens

Overview

Impatiens bloom profusely from late spring until the fall frost, providing bright color to window boxes and containers. When grown as a bedding plant, they create mounds of rich green foliage covered with abundant blooms, making them the top selling bedding plant in the United States, according to the University of Vermont. Routine care includes providing deep weekly watering, adequate nutrients and occasional pruning.

Step 1

Pinch or prune impatiens when they are 4 to 6 inches high by pinching off new growth on the ends of branches. Use your thumb and forefinger to squeeze out center leaves. This forces new growth to sprout along the branch and creates a compact plant with dense foliage capable of supporting abundant blooms.

Step 2

Repeat the procedure in three weeks, pinching out the center leaves on new growth to encourage further branching. Pinching delays blooming but increases the number of branches that later produce blooms. Overall, pinching increases the abundance of blooms.

Step 3

Trim or prune overgrown branches as impatiens mature. Cut back to the overall shape of the plant to improve appearance and promote healthy growth. If impatiens become leggy or cease blooming in midsummer, prune back to a height of 4 inches. A new flush of growth appears quickly and produces new blooms.

Step 4

Prune impatiens back to the soil level in late fall to move the plant inside for the winter. Place in indirect sun and keep soil moist. New growth appears within a few weeks creating an attractive houseplant that can be planted in the garden in spring.
