The String of Arrows, scientifically known as Ceropegia woodii ‘String of Arrows’ or ‘String of Spades’, is a captivating vining plant cherished for its distinct, arrow-shaped leaves. These light green to grey-green leaves, often with silvery variegation, cascade beautifully from hanging baskets. While sometimes mistaken for its close relative, the String of Hearts, its pointed foliage sets it apart. Propagating this plant is a straightforward process to expand a collection or share with others.
Preparing for Propagation
The ideal time to propagate String of Arrows is during its active growing season, typically spring or summer, when the plant naturally puts out new growth. Gather sharp, clean scissors or pruning shears for precise cuts, along with small pots or propagation vessels like glass jars for water or containers for soil. Prepare an appropriate rooting medium, such as distilled or mineralized water, or a well-draining succulent soil mix. Rooting hormone can be used to encourage faster root development, though it is not strictly necessary. Select a healthy, mature parent plant with vigorous growth to ensure the cuttings have the best chance of successful rooting.
Taking Cuttings
Identify a healthy vine on your String of Arrows plant that is at least 3 to 4 inches long. Make a cut just below a node. A node is the point on the stem where leaves emerge, and new roots will develop from these nodes. Remove any leaves from the bottom 1 to 2 inches of the stem, ensuring at least one or two nodes are exposed. Submerged leaves can rot, hindering the rooting process.
Water Propagation Method
Place the prepared String of Arrows cuttings into a clear glass jar or vase. Ensure at least two nodes at the base of each cutting are fully submerged in water, with remaining leaves above the waterline. Change the water every few days or at least once a week to prevent stagnation and bacterial growth. Position the container in a location that receives bright, indirect light, avoiding direct sunlight which can cause the water to heat up or encourage algae growth. Roots typically emerge from the submerged nodes within two to four weeks, and cuttings are ready for transfer to soil once roots are about 1 to 2 inches long.
Soil Propagation Method
Propagating String of Arrows directly in soil involves preparing a well-draining potting mix, such as a commercial cactus or succulent mix amended with perlite or coarse sand for enhanced drainage. Plant the cuttings by burying at least one or two nodes into the prepared soil, ensuring leaves remain above the surface. After planting, lightly moisten the soil, but avoid overwatering, as String of Arrows is prone to rot in overly wet conditions. To create a humid environment that encourages rooting, consider covering the pot with a clear plastic bag or a humidity dome; periodically remove the cover for air circulation and to prevent mold development. Signs of successful rooting, such as slight resistance when gently tugging on a cutting or the appearance of new growth, typically become apparent within a few weeks.
Caring for Your New Cuttings
Once your String of Arrows cuttings have developed a robust root system, they require specific care. Place the newly potted plants in bright, indirect light to encourage healthy growth without scorching their delicate leaves. Water consistently but sparingly, allowing the topsoil to dry completely between waterings, similar to a mature succulent, to prevent root rot. Adequate humidity is beneficial for young plants as they establish, though they tolerate average household humidity. As plants mature, a light application of diluted houseplant fertilizer can be introduced during spring and summer, supporting development without overwhelming young root systems.
