Cloning Impatiens from Stem Cuttings: A Propagation Guide

Overview

With 500+ species worldwide, impatiens offer endless color and low maintenance. Propagation via stem cuttings (cloning) is straightforward but note: most cultivars are patented. Only propagate non-patented varieties or as a licensed grower.

Propagation Steps

Step 1: Prepare Sterile Rooting Medium

Sterilize trays with 10% bleach solution (1:9 bleach:water). Fill with equal parts peat moss and perlite for excellent drainage.

Step 2: Take Tip Cuttings

Using a sharp, clean knife, cut 1-inch tips from vigorous stems. Retain only 2 top leaves. Remove lower leaves, leaving ½ inch of bare stem.

Step 3: Insert and Provide Bottom Heat

Insert cuttings ½ inch deep into medium. Maintain 70-72°F night / 75°F day temperatures for optimal rooting.

Step 4: Maintain Humidity with Misting

Mist several times daily to keep medium moist. Avoid night misting. Callus forms in 5-7 days.

Step 5: Pot Up Rooted Cuttings

When ¼ inch roots appear (10-14 days), transplant to 4-5 inch pots in same peat:perlite mix. No fertilizer yet.

Step 6: Establish Young Plants

Water with plain water for 2 weeks, allowing slight drying between waterings. Prevent wilting. Then begin dilute fertilizer regimen.
