Spider plants (Chlorophytum comosum) are popular houseplants known for their attractive appearance and straightforward care. They are recognized for the small plantlets they produce, often called “spiderettes” or “pups,” which dangle from the mother plant on long stems. This natural characteristic makes them ideal for propagation, allowing enthusiasts to expand their collection.
Why and When to Propagate
Propagating spider plants creates new plants, which can be kept or shared. It also serves as a method to prune a large or aging mother plant. The ideal time for propagation is during the spring and summer growing seasons, when the plant is most active. Plantlets are ready when they have developed small aerial roots or have grown to a size of at least two to three inches with several leaves. Some plantlets may even begin to form roots while still attached to the parent plant, indicating their readiness.
Propagating Spiderettes
Water Propagation Method
To propagate spiderettes in water, select healthy plantlets at least two to three inches long with small root nubs. Using clean, sharp scissors, snip the spiderette from the main plant, leaving a small stem portion.
Fill a shallow glass container with distilled or chemical-free water; tap water can be left out for 24 hours to dissipate chlorine. Remove any lower leaves that would be submerged to prevent rot. Place the spiderette into the water, ensuring only the base with root nubs is submerged and leaves remain above the waterline.
Position the container in bright, indirect sunlight. Change the water every few days or weekly to maintain freshness and prevent bacterial growth. Roots typically form within one to two weeks, and once they are one to two inches long, the plantlet is ready for transplanting into soil.
Soil Propagation Method
For direct soil propagation, select robust spiderettes that show signs of root development or are of a good size. Using clean, sharp scissors, detach the spiderette from the mother plant.
Prepare a small pot, typically around four inches, with drainage holes and fill it with a well-draining potting mix. Create a small divot or hole in the center of the moist soil. Place the spiderette’s base into the hole, ensuring the root area is covered but leaves remain above the surface.
Gently firm the soil around the plantlet for stability. Water thoroughly after planting to settle the mix. Position the potted plantlet in bright, indirect light. Alternatively, the plantlet can be rooted directly in soil while still attached to the mother plant, providing continuous nutrients until it establishes roots, then it can be severed.
Caring for Your New Spider Plant
After propagation, new spider plants require consistent care. Place the newly potted plant in bright, indirect light, avoiding harsh direct sunlight that can scorch leaves. Water regularly, allowing the top inch or two of soil to dry between waterings to prevent sogginess. Spider plants appreciate average indoor humidity, and using chemical-free water, such as distilled or rainwater, can help prevent brown leaf tips.
Tips for Successful Propagation
Selecting healthy, robust spiderettes with small root nubs is important for successful propagation. Sterilize cutting tools with rubbing alcohol before use to prevent disease. Avoid overwatering young plants, as soggy soil can lead to rot. Providing consistent, indirect light encourages healthy development during rooting.
