Caring for Spiderwort

Spiderwort Appearance

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 for Spideirwort

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.

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
