Spiderwort Care

Spiderwort, with its bright flowers and grass-like leaves, is a charming addition to your indoor or outdoor garden. It’s a hardy perennial plant that thrives with minimal care, making it perfect for gardeners of all levels. Understanding the proper care techniques ensures that your spiderwort remains vibrant and healthy. As you delve into the specifics, keep in mind that consistency in care is key to nurturing your spiderwort successfully.

Scientific Classification

Every living thing has its unique place in the natural world. The spiderwort plant is no different. Its scientific classification is like its home address in nature. Here’s how scientists categorize spiderwort:

  • Kingdom: Plantae
  • Subkingdom: Tracheobionta
  • Superdivision: Spermatophyta
  • Division: Magnoliophyta
  • Class: Liliopsida
  • Subclass: Commelinidae
  • Order: Commelinales
  • Family: Commelinaceae
  • Genus: Tradescantia
  • Species: Depends on the specific type of spiderwort


Spiderwort plants enjoy bright, indirect sunlight to thrive. Direct sunlight can harm their leaves. Place them in a room with large windows. If windows face south, use sheer curtains to filter intense rays. Thus, your Spiderwort gets the light it needs without the damage. If you live in a mostly cloudy area, consider using an artificial light source. This can mimic the sun’s light. Keep the plant close to light sources but not in direct sunlight. By getting the light right, your Spiderwort will grow strong and healthy.


Water is vital for spiderwort plants to grow. They like soil that is moist but not soggy. You should water them when the top inch of soil feels dry. Use your finger to check the moisture level. If it’s dry, it’s time to water. Give your plant enough water so that it comes out of the drainage holes at the bottom. This helps avoid salt buildup in the soil. However, don’t let your plant sit in water, as this can cause root rot. During the growing season, which is spring and summer, spiderworts need more water. In winter, water less often because the plant grows slower. Always use room temperature water for your spiderwort. Cold water can shock the roots and cause stress to the plant.


Spiderwort plants are not picky when it comes to soil. They can grow in a variety of soil types. For the best results, you should use a well-draining soil mix. This means the soil should not hold water for too long. If soil holds water for too long, the roots can rot. A mix of potting soil, peat moss, and perlite works well. The perlite helps to keep the soil loose and airy. Spiderworts also like soil that is slightly acidic to neutral. This is a pH level of about 5.5 to 7. You can buy a soil pH test kit to check your soil’s level. It’s important to get the soil right for a happy and healthy spiderwort plant.


When you care for a spiderwort plant, you need to think about its comfort, just like you do with your own. The temperature around the plant is like its weather. Spiderworts enjoy it best when it’s like a pleasant day in spring or fall. They like it when the thermometer shows between 65 and 75 degrees Fahrenheit. It’s too cold for them if it falls below 50 degrees. When it gets that chilly, they might get hurt or even stop growing. You don’t want the plant to shiver, so keep it in a room that’s cozy but not hot. They aren’t fans of super hot temperatures either. If you get this right, your spiderwort will grow happily, just like how you feel good on a day that’s not too hot or cold.


Humidity is the amount of water vapor present in the air. Spiderwort plants like a bit of moisture in their environment, but they don’t need tropical levels of humidity. They are quite adaptable and can thrive in average room humidity. This means you don’t have to do anything special for them in most homes. However, if your home is very dry, you might notice the tips of the spiderwort’s leaves turning brown. This is a sign the air may be too dry for your plant. You can increase humidity by misting the plant lightly with water, placing a tray of water near the plant, or using a small room humidifier. Just be sure not to make the air too damp; this could lead to problems for the plant, like mold.


Fertilizer is food for your spiderwort plant. It helps the plant grow big and strong. You should feed your spiderwort with a balanced liquid fertilizer. This means it has equal parts of the three main nutrients: nitrogen, phosphorus, and potassium. During the growing season, which is spring to early fall, give this fertilizer once a month. But be careful not to overfeed. Too much fertilizer can harm your plant. In winter, when the plant is resting, you don’t need to fertilize. Remember, just like you don’t eat as much when you’re not active, your spiderwort doesn’t need as much food when it’s not growing.

Size & Growth Rate

Spiderwort plants are moderate growers. This means they don’t grow too slowly or too quickly. You can expect a mature spiderwort to reach a size that fits well into most indoor spaces. Typically, a spiderwort grows to be about one to two feet tall and wide. The leaves stretch out and create a grassy, lush look. Each spring and summer, you’ll see new leaves and, if it’s happy, flowers too. The growth rate can vary depending on how much light and water you give the plant. For example, with less light, it might grow slower. However, with the right conditions, a spiderwort can fill out nicely in its pot, giving it a full, healthy appearance. Remember, this plant also spreads out by sending off shoots. Therefore, it can cover more area over time if you plant it outside.

Common Issues

Spiderwort plants can face some problems, just like all plants. One issue is leaf blight, which makes spots or streaks on the leaves. Bugs can also be a bother, like aphids and spider mites that suck on plant juices. These pests are small but can cause big problems if they’re not stopped. Too much water leads to root rot, a tricky problem where the roots get damaged and the plant can’t get nutrients well. On the other hand, if you forget to water your spiderwort, the leaves might turn brown and crispy. Sometimes, the plant can grow too fast and get leggy, which means the stems get long and weak. To keep your spiderwort healthy, you must watch for these issues and act fast if you see them.


Toxicity is about whether a plant is safe for humans and animals to be around. For spiderwort, this is good news. Spiderwort plants are not poisonous. This means if a person or a pet eats part of the plant by accident, they generally won’t get sick from it. However, it’s always smart to be careful. If a lot of the plant is eaten, it might still upset someone’s stomach. But for the most part, spiderwort is considered non-toxic. If a pet nibbles on the plant, you usually don’t need to worry. Still, it’s best to keep an eye on kids and pets when they are around plants. That way, you can make sure they are safe and not eating things they shouldn’t.

Pro Tips

Taking care of spiderwort plants can be easy if you remember these tips:

  • Place your spiderwort in a spot where it gets plenty of bright, indirect light.
  • Water the plant when the top inch of soil feels dry to the touch.
  • Use well-draining soil to prevent water from pooling at the roots.
  • Keep your spiderwort in a room that stays between 60-80 degrees Fahrenheit.
  • Maintain some humidity around the plant, but don’t let it get too damp.
  • Feed your spiderwort with a balanced fertilizer every month during the growing season.
  • Prune the plant to encourage bushy growth and to remove any dead or yellow leaves.
  • Keep an eye out for pests like aphids or spider mites, which can be treated with insecticidal soap.
  • Repot your spiderwort every couple of years to give it fresh soil and more room to grow.
