Grow orchids in water: an abundance of roots
One of the most fascinating and innovative ways to grow orchids is to grow them in water. Unlike the traditional method with a coconut or bark fibre substrate, hydroponic cultivation offers many advantages and can lead to an abundance of healthy and vigorous roots.
Orchids are exotic and delicate plants that require specific conditions to thrive. By cultivating orchids in water, roots can easily absorb the moisture, nutrients and oxygen they need to develop optimally.
Here is a step-by-step guide to growing orchids in water:
- Choose a transparent container: Opt for a glass or transparent plastic vase that will allow light to penetrate and promote root photosynthesis.
- Fill the container with pure water: Use filtered or distilled water to avoid accumulation of mineral salts or substances harmful to orchids.
- Place the orchids in the container: Make sure the orchid roots are immersed in the water, but make sure the leaves and pseudobulbs stay outside to avoid rot.
- Change water regularly: Renew water every two weeks to prevent stagnation and ensure optimal absorption of nutrients by the roots.
- Fertilize sparingly: Add a diluted orchid fertilizer in the water every six weeks to bring nutrients essential for plant growth.
- Ensure temperature and exposure to light: Orchids prefer mild temperatures and indirect light exposure to thrive in an aquatic environment.
Growing orchids in the water can be a rewarding experience that allows you to observe closely the development of the roots and appreciate the beauty of these extraordinary plants. With good care and regular attention, your orchids could thrive and offer you an abundance of colorful and fragrant flowers.
