How to Propagate Spider Plant Babies in Water

Spider plants are known for their arching leaves and the offshoots, or “babies,” that grow on long stems called runners. Propagating these plantlets is a straightforward way to create new spider plants for your home. Using water for propagation is a common method that allows you to observe the rooting process directly.

Preparing Plantlets for Propagation

The first step is to select a healthy plantlet for propagation. A mature spider plant will naturally produce these small offshoots. Look for plantlets that have developed small nubs or tiny, visible aerial roots at their base, as this indicates they are ready to grow independently.

Once you have identified a suitable plantlet, you will need to separate it from the parent plant. Using a clean pair of scissors or small pruning shears, carefully snip the runner. Make the cut close to the base of the plantlet, leaving less than an inch of the stem attached.

The Water Propagation Process

With the plantlet prepared, the next stage is placing it in water to encourage root development. A small, clear glass jar or vase is an ideal container because it allows you to easily watch for new root growth. Fill the container with enough water to submerge the very base of the plantlet where the roots will emerge, but be careful not to let the leaves sit in the water, as this can cause them to rot.

Tap water is adequate, though letting it sit out for 24 hours can allow chlorine to dissipate. Place the container in a location that receives bright, indirect sunlight. Direct sun can be too intense, potentially scorching the leaves or encouraging algae to grow in the water.

Change the water every few days, or as soon as it becomes cloudy, to prevent the buildup of harmful bacteria. Within one to two weeks, you should begin to see the first signs of new, white roots emerging from the base of the plantlet. Continue to refresh the water as these roots grow and lengthen.

Transitioning from Water to Soil

Once the plantlet has a healthy root system, it is time to move it to soil. The ideal time to transplant is when the roots have reached a length of one to two inches. Roots that are grown in water can be more delicate, so handling them gently during this process is recommended.

For potting, select a small container with drainage holes at the bottom. Fill the pot with a well-draining potting mix. Create a small hole in the center of the soil and carefully place the rooted plantlet inside, gently spreading the roots. Cover the roots with soil, ensuring the base of the plant is secure.

After planting, water the soil thoroughly to help it settle around the roots. For the first couple of weeks, keep the soil consistently moist but not waterlogged. Once you observe new leaf growth, you can begin a more standard watering routine.
