How to Grow and Care for Spider Plants

Spider plants produce a rosette of long, thin, arched foliage that is solid green or variegated with white. These easy-to-grow houseplants look especially nice in a hanging basket and were a favorite in Victorian-era households. Here’s how to grow spider plants in your home!

About Spider Plants

During the summer, spider plants may produce tiny white flowers on long stems, as well as baby spider plants (offsets) called “pups.” The pups look like tiny spiders, hence the plant’s name!

Spider plants were once highlighted by NASA for their reported air-purifying ability, though a large amount of plants would be required to reap any benefits in the home. Nonetheless, they are a classic and attractive plant to add to your space.

Planting
  • Grow in a soil-based, well-draining potting mix. Spider plants like even moisture; they don’t like to be too dry or too wet.
  • Keep plants in bright to moderate indirect sunlight. Spider plants do not appreciate direct, hot sunlight, which can burn their leaves, causing brown tips and spots.
  • Spider plants grow fairly quickly and can easily become pot bound. Plan to repot a spider plant about every other year.
  • Spider plants can be grown outdoors as annuals during the summer. They look especially good along the edge of a container or bed, as long as they are kept out of direct sunlight.
Growing
  • During initial growth, water occasionally; once fully developed (within one year), water moderately. 
  • In the spring and summer months, keep the soil moist to encourage growth. Do not let soil dry out too much.
  • Maintain average room temperature and humidity. Spider plants prefer temperatures between 55 and 80°F (13–27°C), which makes them a great indoor houseplant.
  • Fertilize up to twice a month in the spring and summer, however, avoid overfertilization.

Harvesting
  • Healthy spider plants may eventually produce “pups,” which are offshoots from the adult plant that can be removed and replanted to start new plants. For the best results, allow pups to reach approximately two inches in diameter before removing them from the mother plant. 

    Alternatively, set the still-attached pups into pots of soil placed next to the mother plant. Once the pups have rooted themselves to the soil, they can be cut loose from the mother plant.
Wit and Wisdom
  • Spider plants also go by the names “airplane plant,” “ribbon plant,” and “spider ivy.”
  • Spider plants are originally from South Africa.
  • Keep spider plants on your desk to reduce indoor pollutants.
Pests/Diseases
  • Spider plants are prone to tip burn, which can be caused by dry soil, low humidity, or a buildup of salt and chemicals that are found in some public tap water. Keep the soil slightly moist. Avoid watering with fluoridated or chlorinated water and cut off brown tips if they do occur. 
  • To get rid of the brown discs on leaves, use your fingernail to scrape off the brown residue every few days.
  • Mealybugs
  • Scale
