Monstera Care Tips
Monstera plants, known for their striking foliage, are popular indoor plants. Though they are easy to care for, proper attention is crucial to keep them thriving. Below are essential care tips to help your Monstera flourish.
Watering And Light
Monstera plants prefer moderate watering. Allow the top inch of soil to dry out before the next watering. Overwatering can cause root rot. Ensure the pot has drainage holes to prevent water from sitting at the bottom.
These plants thrive in bright, indirect light. Direct sunlight can scorch their leaves. If the light is too low, growth may slow down, and the leaves may not develop their characteristic splits.
| Watering | Light |
|---|---|
| Moderate, when top inch is dry | Bright, indirect light |
| Ensure good drainage | Avoid direct sunlight |
Pruning And Repotting
Regular pruning helps maintain the shape and size of your Monstera. Use clean, sharp scissors to remove dead or yellowing leaves. This encourages new growth and keeps the plant healthy.
Repotting is necessary when the plant outgrows its current pot. A larger pot gives the roots more room to grow. Repot your Monstera every 1-2 years, preferably in spring. Use a well-draining potting mix suitable for tropical plants.
- Remove dead or yellowing leaves
- Repot every 1-2 years
