Today we will answer that question and more. You’ll also learn how to care for your Calathea to help it grow at its best.
Let’s dive in!
How Big Do Calathea Grow?
Calathea plants usually grow to 1 to 3 feet tall indoors. Their leaves can spread up to 2 feet wide, creating a lush, full look. The exact size depends on the type of Calathea and how well you care for it.
Typical Dimensions
- Height: 1 to 3 feet
- Width: Up to 2 feet
These plants grow well in pots and are perfect for small to medium spaces.
What Affects Calathea Growth?
Calathea growth depends on several factors, like light, water, humidity, and care. Here’s how each one matters:
1. Light Needs
Calatheas thrive in bright, indirect light. Too much direct sunlight can scorch their leaves, while too little light can slow their growth.
Tip: Place your Calathea near a window with filtered light or use sheer curtains.
2. Watering
These plants love moist soil but hate sitting in water. Overwatering can cause root rot, while underwatering can lead to curling leaves.
Tip: Water your Calathea when the top inch of soil feels dry.
3. Humidity Levels
Calatheas are tropical plants that need high humidity to thrive. Low humidity can make their leaves brown and crispy.
