Tradescantia species, commonly known as Wandering Dude, Inchplant, or Wandering Jew, are popular houseplants due to their colorful, trailing foliage and ease of propagation. The plant naturally grows long, “leggy” stems, making propagation a necessary step to maintain a dense, bushy appearance. Creating new plants from stem cuttings is a reliable method, which allows gardeners to multiply their collection quickly. The process is straightforward, whether rooting the cuttings in water or directly in soil.
Preparing Cuttings for Propagation
Successfully propagating Tradescantia begins with selecting healthy stem pieces from the parent plant. Choose robust stems with vibrant coloring, looking for sections roughly three to five inches long. Use a clean, sharp tool, such as sterilized scissors or pruning shears, to make a precise cut and minimize the risk of introducing pathogens.
The cut must be made just below a node, which is the joint where a leaf connects to the stem. This area contains the cells ready to initiate new root growth. After cutting, gently strip all leaves from the bottom inch or two of the stem to fully expose at least two nodes. Submerged leaves will rot in the rooting medium, which prevents the cutting from developing roots.
Rooting Cuttings in Water
Rooting cuttings in water is a preferred method because it allows you to observe the root development process. Place the prepared cuttings into a small glass or jar filled with clean water, ensuring at least one node is fully submerged. Use a vessel with a narrow neck to hold the cuttings upright and keep the leaves out of the water.
Position the container in a location that receives bright, indirect light. Tiny white roots should begin to emerge from the nodes within one to three weeks. Change the water completely every few days, or at least once a week, to prevent the buildup of bacteria or algae. Once the new roots are about one to two inches long, the cuttings are ready to move to a solid growing medium.
Rooting Cuttings Directly in Soil
An alternative method is to root the prepared stem cuttings directly into a potting mix. This approach produces roots already acclimated to soil, which can lead to faster establishment compared to water-rooted cuttings. Fill a small pot with a well-draining soil blend, such as a mix amended with perlite or peat moss for aeration.
You may dip the exposed nodes into rooting hormone powder, though this is usually unnecessary. Insert the cutting deep enough to bury at least one node, lightly firming the mix around the stem for stability. Keep the soil lightly moist and place the pot in bright, indirect light to encourage root development and maintain vibrant colors. Planting several cuttings together creates an immediately full and lush new plant.
Post-Propagation Care and Troubleshooting
Once the roots have grown to a sufficient length, the new plant requires specific care to thrive. If rooted in water, transplant the cuttings into a well-draining soil mix once roots are one to two inches long, then water thoroughly to settle the soil around the delicate roots. Place the newly potted plant in a spot with bright, indirect light; insufficient light will cause the stems to stretch and become “leggy.”
The most common issue during rooting is stem rot, which appears as black or mushy tissue caused by overly wet conditions or submerged leaves. To prevent rot, allow the top inch of soil to dry out between waterings after the initial planting. If rooting is slow, the issue is often insufficient warmth or light; move the container to a warmer, brighter location to stimulate growth. Newly propagated plants need consistent moisture for the first few weeks, then transition to the standard Tradescantia watering schedule.
