Spider plants (Chlorophytum comosum) are a timeless favorite among houseplant enthusiasts, and for good reason. These resilient and attractive plants offer a host of benefits, making them ideal additions to any indoor space. Beyond their aesthetic appeal with arching variegated leaves and playful plantlets, spider plants are incredibly easy to care for, even for beginners. They also act as natural air purifiers, helping to remove toxins from your home, and are non-toxic to pets, adding to their family-friendly charm. Whether you’re a seasoned plant parent or just starting your indoor garden journey, understanding the simple steps to care for spider plants indoors will ensure these leafy companions thrive in your home.
Spider Plant Care Essentials
Providing the right environment is key to keeping your spider plant happy and healthy indoors. While adaptable, spider plants have specific preferences when it comes to light, soil, water, temperature, and fertilization. Mastering these basics will set you up for success in growing lush and vibrant spider plants.
Light
Spider plants flourish in bright, indirect light, mimicking their natural habitat under the canopy of trees. Indoors, an east-facing window or a spot near a south or west-facing window filtered by sheer curtains is ideal. Too much direct sunlight can scorch their delicate leaves, leading to unsightly brown patches. Conversely, insufficient light can result in leggy growth and a loss of variegation in striped varieties. Observe your plant: if the leaves appear pale or stretched, it might need more light. If you notice burnt tips or bleached areas, relocate it to a spot with gentler, indirect sunlight.

Soil
For optimal growth, spider plants need well-draining, loamy soil. A standard houseplant potting mix generally works well. The key is to ensure good drainage to prevent waterlogged roots, which can lead to root rot. You can improve drainage by adding perlite or vermiculite to your potting mix. Spider plants are not particularly fussy about soil pH, but a slightly acidic to neutral range is preferred. Avoid heavy, compacted soils that retain too much moisture.

Watering
Consistent watering is crucial for healthy spider plants, especially during the active growing season (spring and summer). Aim to keep the soil consistently moist but not soggy. Water thoroughly when the top inch of soil feels slightly dry to the touch. Overwatering is a more common problem than underwatering and can lead to root rot. Ensure your pot has drainage holes to allow excess water to escape.
Consistent Watering
Spider plants are somewhat drought-tolerant due to their fleshy tubers that store water, but they thrive on consistent moisture. Using a moisture meter can be helpful to gauge the soil moisture level accurately. Water your spider plant when the meter reading approaches “dry,” indicating the plant is ready for a drink. In winter, when growth slows down, reduce watering frequency, allowing the soil to dry out slightly more between waterings. Be mindful of water quality; spider plants are sensitive to fluoride and chlorine often found in tap water. Using rainwater, distilled water, or letting tap water sit out overnight can help reduce these chemicals and prevent brown tips on the leaves.
Temperature and Humidity
Spider plants are native to tropical and subtropical regions and prefer warm and humid environments. Maintain indoor temperatures between 65°F to 80°F (18°C to 27°C) for optimal growth. Avoid placing them near drafts, cold windows, or air conditioning vents, as sudden temperature fluctuations can stress the plant. While they can tolerate average household humidity levels, spider plants appreciate higher humidity. Boosting humidity, especially in dry winter months, can be beneficial. You can increase humidity by misting your spider plant regularly, placing it on a pebble tray filled with water, or using a room humidifier. Aim for a humidity level of 50-60% for the best results.
Fertilizing
Spider plants benefit from regular fertilization during their active growing season (spring and summer). Fertilize monthly with a balanced, water-soluble houseplant fertilizer diluted to half strength. Over-fertilizing can be detrimental, leading to brown leaf tips due to salt buildup in the soil. If you notice white crusts on the soil surface, this could be a sign of fertilizer salt buildup. Flush the soil with water to remove excess salts. Reduce or cease fertilization during the fall and winter months when the plant’s growth naturally slows down. Yellowing leaves can indicate nutrient deficiency, signaling the need for fertilization during the growing season.

Choosing the Right Pot and Repotting
Selecting the appropriate pot and repotting your spider plant when needed are essential for its long-term health. Opt for pots with drainage holes to prevent waterlogging. Terracotta pots are a good choice as they allow for better aeration and drainage compared to plastic pots. Choose a pot size that is only slightly larger than the root ball, about 1-2 inches wider in diameter. Overly large pots can retain too much moisture and increase the risk of root rot.
Spider plants typically need repotting every 1-2 years, or when they become root-bound. Signs that your spider plant needs repotting include roots circling the pot, roots growing out of the drainage holes, or the plant drying out too quickly after watering. Spring is the ideal time for repotting. Gently remove the plant from its old pot, loosen the root ball, and place it in the new pot filled with fresh potting mix. Ensure the plant is positioned at the same depth as before. After repotting, water thoroughly and allow the plant to adjust to its new container.
Pruning and Propagation
Pruning and propagation are simple tasks that can help maintain the health and appearance of your spider plant and even multiply your collection.
Pruning
Regular pruning helps to keep your spider plant tidy and encourages bushier growth. Remove any dead, brown, or yellowing leaves as they appear to maintain the plant’s aesthetic appeal and prevent potential disease issues. You can also trim back any leggy or overgrown stems to maintain a desired shape. Spider plants produce “spiderettes” or “plantlets” on long stems, which are baby plants. You can prune these plantlets if you wish to redirect the plant’s energy back into foliage growth, or you can propagate them to create new spider plants.
Propagation
Spider plants are incredibly easy to propagate, primarily through their plantlets. Once the plantlets develop small aerial roots, they are ready for propagation. You can propagate spider plants in two main ways:
-
Plantlet Propagation in Soil: Cut the plantlets from the mother plant using clean pruning shears, ensuring you include the small root nodes. Plant the plantlets directly into small pots filled with moist potting mix. Keep the soil consistently moist and provide bright, indirect light. The plantlets should root and begin to grow within a few weeks.
-
Plantlet Propagation in Water: Alternatively, you can root plantlets in water first. Place the cut plantlets in a jar of water, ensuring the base of the plantlet is submerged, but the leaves remain above water. Once roots develop that are about an inch or two long, you can transplant the plantlets into pots with potting mix.
Mature spider plants can also be propagated by division during repotting. Carefully divide the root ball into sections, ensuring each section has roots and foliage. Replant each division into its own pot.
Common Spider Plant Problems and Solutions
Spider plants are generally resilient, but like all houseplants, they can encounter a few common problems.
Brown Leaf Tips
Brown leaf tips are a frequent concern with spider plants. The most common causes are fluoride and chlorine in tap water, over-fertilization, low humidity, or dry soil. To address brown tips:
- Use filtered water, rainwater, or let tap water sit out to dechlorinate.
- Reduce fertilizer frequency and ensure proper dilution.
- Increase humidity around the plant.
- Check soil moisture and water consistently.
- Trim brown tips with clean scissors, cutting at an angle to mimic the natural leaf shape.
Sparse Plant
A sparse or leggy spider plant can result from insufficient light or being root-bound. Ensure your plant receives bright, indirect light. If the plant is root-bound, repot it into a slightly larger container to give the roots more room to grow and encourage fuller foliage. Pruning plantlets can also redirect energy to the mother plant, promoting denser growth.
Pests and Diseases
Spider plants are relatively pest-resistant, but they can occasionally be affected by common houseplant pests like aphids, spider mites, and whiteflies. Regularly inspect your plant for signs of infestation, such as webbing, sticky residue, or visible insects. If pests are present, rinse the plant thoroughly with water to dislodge them. For more severe infestations, insecticidal soap or neem oil can be used according to product instructions. Root rot is the most common disease in spider plants, usually caused by overwatering and poor drainage. Prevent root rot by ensuring well-draining soil and avoiding overwatering.
Types of Spider Plants
While the classic green and white variegated spider plant is widely recognized, several attractive varieties offer subtle variations:
- Chlorophytum comosum ‘Variegatum’: Features green leaves with creamy white margins.
- Chlorophytum comosum ‘Vittatum’: Displays leaves with a central white stripe and green edges.
- Chlorophytum comosum ‘Bonnie’: A compact variety with charmingly curled leaves and a central cream stripe.
