The Spiderwort plant is a tropical houseplant prized for its foliage with eye-catching patterns. Also called the Inch Plant, Spiderwort is native to Mexico, South America, and the Caribbean. This low-maintenance plant grows well in both soil or hydroponically.
The Spiderwort plant has a vining growth habit. When grown outdoors, this fast-growing plant often becomes invasive. As a houseplant, Spiderwort is much easier to contain and care for. The plant’s foliage features beautiful stripes and patterns, which vary depending on the variety. Blooming can happen any time of the year. The flowers feature three petals and come in a variety of colors including white, purple, and pink.
Spiderwort Sunlight Requirements
Proper care of your Spiderwort plant recommends providing bright, indirect sunlight for at least eight hours per day. Avoid direct sunlight exposure as it will scorch the beautiful foliage. Fading variegation indicates too little sunlight. Supplement low lighting with an LED grow light if needed.
Watering Your Spiderwort Plant
Spiderwort prefers a consistently moist environment. Water your plant when the first two to three inches of soil feels dry when a finger is inserted. On average, water the plant once per week during the spring and summer growing months. Reduce waterings in the fall and winter.
Soil and Fertilizer
If growing Spiderwort in soil, provide a well-draining medium to help avoid root rot. Use a good-quality potting soil amended with a little sand for added drainage and some organic matter for nutrients. Ensure you grow the plant in a pot with drainage holes to allow for excess water to escape. Feed your Spiderwort plant once or twice a month with a water-soluble fertilizer diluted to half strength.
Temperature and Humidity Levels
Maintain temperatures of between 65 to 75 degrees Fahrenheit (18.3 to 23.8 Celsius). Avoid temperatures below 50F as it causes discoloration and damage to the foliage. Spiderwort prefers above average humidity. Use a humidifier to boost levels or place the plant in a kitchen or bathroom where humidity is naturally higher.
Due to its fast growth, the Spiderwort plant tends to get leggy if not pruned. Care for your Spiderwort by cutting back the stems to the joint periodically. Prune or pinch back 25% of the plant to keep it healthy.
Spiderwort propagates best by cuttings. Snip a one-inch stem with at least one leaf attached. Plant the stem in a pot filled with a light potting soil. Keep the soil moist and in a warm place with indirect sunlight. Roots will form in a few weeks. Alternatively, you can place the stem in a glass of water. Change the water every few days and keep the stem in the same growing conditions.
Common Pests and Diseases
Aphids and spider mites are common pests to watch for. If an infestation occurs, care for spiderwort plants by separating it from the rest of your plants to avoid spread. Treat the plant with neem oil to rid the plant of the harmful insects.
Root rot is the most common disease in Spiderwort. Rot is caused by overwatering the plant or by poor-draining soil. Remove any damaged leaves or roots to stop the spread. Decrease watering and change out the soil if it is the problem.
Spiderwort is a common and well-liked houseplant with stunning foliage. The plant’s care needs are straightforward and the plant adapts well to moist home environments. Add this fast-growing houseplant to your collection and enjoy it for years to come.
