Cannas Plant:
Indoor Growing Tips for a Lush and Healthy Plant

Updated: March 22, 2023

Cannas are a popular plant known for their vibrant and colorful blooms. These plants are easy to grow and are perfect for indoor gardening. With a little bit of care, you can have a lush and healthy Canna plant that will brighten up any room in your home.

Choosing the Right Pot

When it comes to growing Cannas indoors, choosing the right pot is essential. The pot should be large enough to accommodate the plant’s root system and allow for proper drainage. A pot that is too small can cause the roots to become crowded, which can lead to stunted growth and poor health.

Soil Requirements

Cannas prefer well-draining soil that is rich in nutrients. You can use a quality potting mix or create your own by mixing equal parts of peat moss, vermiculite, and perlite. Adding compost to the soil can also help provide a steady supply of nutrients to the plant.

Watering

Watering is an essential part of caring for your Canna plant. It is important to keep the soil evenly moist, but not waterlogged. Overwatering can lead to root rot and other problems. Water your plant when the top inch of soil feels dry to the touch. During the winter months when the plant is dormant, reduce watering frequency.

Lighting Requirements

Cannas require bright light to grow and bloom properly. Place your plant near a sunny window where it can receive at least six hours of direct sunlight each day. If you do not have a sunny window, you can use artificial grow lights to provide the necessary light.

Temperature and Humidity

Cannas prefer warm temperatures between 65-75°F (18-24°C). They also prefer humidity levels between 50-60%. If the air in your home is dry, you can use a humidifier or place a tray of water near the plant to increase humidity levels.

Fertilizing

Fertilizing your Canna plant is important for healthy growth and blooming. You can use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Fertilize your plant every two weeks during the growing season (spring and summer) and reduce fertilization during the winter months.

Troubleshooting Common Problems

If you notice any problems with your Canna plant, it is important to address them as soon as possible. Here are some common problems and their solutions:

  • Yellowing leaves: This can be caused by overwatering or nutrient deficiencies. Allow the soil to dry out between waterings and fertilize regularly.
  • Wilting: This can be caused by underwatering or root rot. Check the soil moisture level and adjust watering accordingly.
  • Pests: Cannas can be prone to spider mites, thrips, and aphids. Use an insecticidal soap or neem oil to control these pests.
