Peace Lily Growth Factors
How big your peace lily gets depends on a few things. Let’s look at what helps them grow.
Light and Temperature: The Ideal Environment
Peace lilies like bright, indirect light. They don’t like direct sunlight. The best temperature for them is between 65°F and 80°F.
Key Points:
- Bright, indirect light is best.
- Keep them in a warm place.
- Light helps them grow big and strong.
Watering and Humidity: Essential for Size
Peace lilies like their soil to be moist, but not soggy. Water them when the top inch of soil feels dry. They also like humidity, so you can mist them with water.
Key Points:
- Water when the soil is a little dry.
- Humidity helps them grow big leaves.
- Don’t overwater them.
Soil and Fertilization: Nourishing Growth
Use a well-draining soil mix for your peace lily. Feed them with a balanced fertilizer every 6-8 weeks during the growing season.
Key Points:
- Good soil helps the roots grow.
- Fertilizer gives them the food they need.
- Healthy roots mean a bigger plant.
Potting and Repotting: Providing Room to Grow
When your peace lily gets too big for its pot, it’s time to repot it. Choose a pot that’s a little bigger than the current one.
Key Points:
- Repotting gives the roots more space.
- Choose a slightly bigger pot.
