The String of Pearls plant (Senecio rowleyanus or Curio rowleyanus) is a popular houseplant, recognized by its cascading strands of spherical, pea-like leaves. While relatively low-maintenance, repotting is important for their long-term health and continued growth. Due to their delicate nature, careful handling during repotting is essential to prevent damage.
Knowing When It’s Time to Repot
String of Pearls plants have shallow root systems and can thrive in the same container for extended periods, so repotting is not frequent. Generally, repotting is needed every two to five years, or when the plant shows signs of outgrowing its pot. Signs include roots emerging from drainage holes, indicating the plant is root-bound, or stunted growth despite consistent care.
Repotting is also needed if the existing soil appears depleted, compacted, or no longer drains effectively. Additionally, if the plant shows signs of root rot or pest infestation, a soil change can address these issues. The optimal time for repotting is during the active growing season, typically spring or early summer, as this allows the plant to recover and establish more readily in its new container.
Gathering Your Repotting Supplies
When selecting a new pot, choose one that is only one to two inches larger in diameter than the current pot. Opting for a pot that is too large can lead to excessive moisture retention in the soil, which increases the risk of root rot. Ensure the new pot has ample drainage holes at its base. Terracotta or unglazed ceramic pots are often recommended for String of Pearls because their porous nature helps absorb excess moisture and promotes better airflow to the roots.
String of Pearls plants require a well-draining succulent or cactus mix to prevent waterlogging. These mixes typically contain components like perlite, pumice, or coarse sand, which enhance drainage and aeration. You can purchase pre-made succulent mixes or create your own by combining potting soil with perlite, sand, or bark in suitable proportions. Having gardening gloves and a small trowel can assist in handling the delicate strands and soil during the process.
The Gentle Repotting Process
Repotting a String of Pearls requires a gentle approach due to its delicate stems and shallow root system. Begin by carefully gathering the plant’s trailing strands and gently coiling them on top of the soil or loosely tying them to keep them out of the way. Next, gently remove the plant from its current pot by tipping it on its side and lightly pressing on the sides of the container. Avoid pulling directly on the plant’s stems, as they can easily break.
Once the plant is out, inspect the root ball for any signs of rot or damage; healthy roots appear firm and white or tan. If you find any mushy or dark roots, carefully trim them away with clean, sharp scissors. Add a layer of fresh, well-draining succulent or cactus mix to the bottom of the new pot, ensuring the plant will sit at roughly the same depth as it was in its previous container. Carefully center the String of Pearls in the new pot, then fill in around the root ball with more soil, gently pressing down to remove air pockets and secure the plant. It is important not to bury the pearls or stems too deeply, as they prefer to be near the soil surface for proper air circulation.
Post-Repotting Care
After repotting your String of Pearls, a brief adjustment period is beneficial for the plant’s recovery. It is generally advised to delay the first watering for several days, typically five to ten days, to allow any disturbed roots to heal and minimize the risk of root rot. This waiting period helps the plant settle into its new environment and reduces stress.
During this recovery phase, place the repotted plant in a location that receives bright, indirect sunlight. While String of Pearls plants appreciate ample light, direct, intense sunlight immediately after repotting can cause stress or scorch the delicate leaves. Avoid applying fertilizer immediately after repotting, as the fresh soil mix provides sufficient nutrients for the initial period. Continue to monitor the plant closely for any signs of stress, such as wilting or yellowing, adjusting its light conditions if necessary to ensure it thrives in its new pot.
