Yes, it is possible to cultivate Calatheas in water, though it requires some special care. Here are a few tips for growing Calatheas in water:
Use a Container with Good Drainage To prevent water stagnation, choose a container with good drainage or use a clear glass vase that allows you to observe the roots. This helps reduce the risk of root rot.
Change the Water Regularly Change the water every week to ensure that the roots stay healthy and don't accumulate algae or harmful bacteria. Fresh water promotes better growth.
Provide Adequate Light Calatheas thrive in bright, indirect light. Place your container in a location where it receives plenty of light but is not exposed to direct sunlight, which could burn the leaves.
Monitor for Root Growth After placing the Calathea in water, monitor its root development. Roots should begin to grow within a few weeks. If you notice stunted growth, it might be helpful to provide a water-soluble fertilizer.
Consider Adding Nutrients While Calatheas can survive in water for a while, they will need additional nutrients for long-term growth. You can add a liquid houseplant fertilizer to the water every few weeks to ensure they get the essential nutrients.
Growing Calatheas in water is a feasible option, but it requires careful attention to water changes, light, and nutrients. With the right care, they can thrive and add beauty to your home.
