The Chlorophytum comosum, more commonly known as the spider plant or airplane plant, is a very popular houseplant, and for good reason! Not only is it easy to care for, but it also has recognized air-purifying properties. This complete guide offers tips and advice on how to care for your Chlorophytum and help it thrive.
How to Care for a Chlorophytum comosum for Optimal Growth
Here are the key points to remember for optimal care:
Light:
- Opt for bright, indirect light. Place the plant near an east- or west-facing window, avoiding direct sunlight, especially during the hottest hours, which could burn the leaves.
- Partial shade is tolerated, but growth will be less vigorous and the colours less pronounced.
Watering:
- Water moderately, allowing the top inch or so (about 2-3 cm) of soil to dry out between waterings.
- Generally, watering every 1 to 2 weeks is sufficient, but the frequency may vary depending on the temperature and ambient humidity. Reduce watering in winter, when the plant is in a period of dormancy.
- Always empty any standing water from the saucer after watering to prevent root rot.
Water Quality:
- The Chlorophytum is sensitive to fluoride and chlorine present in tap water. Preferably use filtered water, collected rainwater, or tap water that has been left to sit for 24 hours to allow the chlorine to evaporate.
- Avoid hard water, which can leave white spots on the leaves.
Humidity:
- Although the Chlorophytum tolerates dry indoor air, it appreciates a slightly humid atmosphere.
- Regularly mist the foliage with non-hard water, especially in winter when heating dries out the air. You can also place the pot on a saucer filled with damp clay pebbles.
Temperature:
- The ideal temperature is between 18 and 24°C (64 and 75°F).
- Avoid cold drafts and temperatures below 10°C (50°F), which can damage the plant.
Repotting:
- Repot your Chlorophytum every 1 to 2 years, preferably in the spring, into a slightly larger pot (1 to 2 cm or about ½ inch larger in diameter).
- Use a good quality, well-draining potting mix for houseplants.
- Ensure good drainage by placing a layer of clay pebbles or gravel at the bottom of the pot.
Fertilizing:
- During the growing season (spring and summer), apply a liquid houseplant fertilizer once a month, respecting the doses indicated on the packaging.
- Reduce or suspend fertilizer applications in the fall and winter.
Toxicity to Animals: Generally Non-Toxic
Health and Environmental Benefits: An Air-Purifying Ally (with a Caveat)
The Chlorophytum comosum is often cited for its air-purifying properties, notably thanks to studies conducted by NASA. It has been shown to absorb certain common pollutants such as formaldehyde, xylene, and carbon monoxide. It is important to note that the effectiveness of this purification in real-world conditions depends on many factors. Nevertheless, it contributes to improving indoor air quality.
How to Propagate a Spider Plant: A Simple and Fun Method
Propagating the Chlorophytum comosum is very easy thanks to its plantlets (also called spiderettes or pups):
- Cut the plantlets using clean scissors, making sure to leave a few centimetres of stem.
- Place the plantlets in water until roots develop.
- Plant the rooted plantlets in a pot with houseplant potting mix.
You can also plant the plantlets directly in the soil, keeping them moist until they root.
What are the Common Problems of the Chlorophytum comosum and How to Solve Them?
- Brown Leaf Tips: Often caused by dry air, underwatering, over-fertilizing, or sensitivity to fluoride in tap water.
- Root Rot: Due to overwatering or poor drainage.
- Pale or Yellowing Leaves: May indicate a lack of light.
Easy to care for, decorative, and contributing to improving air quality, the spider plant is an ideal plant for all interiors, whether you are a beginner or an experienced gardener. With its easy-to-propagate plantlets, you can quickly expand your collection and share this plant with your friends and family.
