Calla lilies can be grown in water, making them versatile and easy-to-care-for plants for indoor gardening.
Growing calla lilies in water is a popular method for showcasing their elegant blooms up close and maintaining them in a simple setup without soil.
In this post, we’ll explore how calla lilies can be grown in water, the best ways to do it, and some helpful tips to keep your watery calla lilies thriving.
Let’s dive into the beautiful world of water-grown calla lilies.
Why Calla Lilies Can Be Grown In Water
Calla lilies can be grown in water because they have strong rhizomes that can adapt to absorbing nutrients directly from water instead of soil.
1. Adaptable Rhizomes Allow Root Growth In Water
Calla lilies grow from rhizomes, which are thick, underground stems that store nutrients.
These rhizomes can develop roots in water, feeding the plant without the need for traditional soil.
Because of this adaptability, calla lilies are one of the few flowering plants that can thrive when grown hydroponically.
2. Nutrient Absorption Through Water
When calla lilies are grown in water, essential nutrients must be supplied through water-soluble solutions.
This way, the rhizomes and roots get the minerals and nourishment they need to grow and bloom just as they would in soil.
It’s important to provide balanced nutrients tailored for hydroponic or aquatic plants to avoid deficiencies.
3. Reduced Risk of Soil Pests And Diseases
Growing calla lilies in water eliminates soil-related pests and fungi that can affect the health of the plant.
This cleaner environment reduces the risk of root rot if water conditions are properly managed, making it a low-maintenance growing method.
Since water can be changed frequently, it also limits buildup of harmful pathogens.
How to Successfully Grow Calla Lilies in Water
If you wonder how to grow calla lilies in water, it’s easier than you might think with just a few steps and the right care.
1. Choose Healthy Rhizomes or Plants
Start by selecting quality calla lily rhizomes or young plants from a nursery.
Look for firm rhizomes without mold or damage for the best chance of rooting successfully in water.
Alternatively, you can also start with a potted calla lily and transition it carefully to a water setup.
2. Prepare the Water Container
Use a clear vase or water container that is tall enough to support the calla lily stems.
Fill it with room temperature water, preferably filtered or distilled to avoid chlorine or chemicals.
The rhizomes should be partially submerged—avoid covering the entire rhizome to prevent rot.
3. Provide Nutrients Regularly
Since water alone doesn’t contain essential nutrients, add a liquid fertilizer made for water plants every two weeks.
Look for balanced formulations with nitrogen, phosphorus, and potassium to support healthy growth and blooming.
Changing the water weekly will also prevent stagnation and keep the environment oxygenated.
4. Place in Bright, Indirect Light
Calla lilies perform best with bright but indirect sunlight.
Place the water container near a window where it can receive plenty of light without harsh direct rays that could overheat the water or stress the plant.
Too little light can delay blooming and affect the overall health of calla lilies grown in water.
5. Maintain Water Quality and Temperature
Keep the water temperature around 60 to 70°F (15–21°C) for optimal root and plant health.
Avoid placing the water container near heating vents or cold drafts.
Regularly changing the water and cleaning the container every few weeks keeps algae and bacteria at bay.
Benefits of Growing Calla Lilies in Water
Growing calla lilies in water offers unique advantages that soil planting can’t always provide.
1. Showcases Stunning Blooms and Roots
One of the biggest benefits of growing calla lilies in water is the ability to see the elegant flowers and their beautiful, intricate roots through a clear vase.
This makes a gorgeous and natural decoration for your home or office.
2. Space-Saving and Cleaner
Water-growing takes up less space than soil containers and avoids messy soil spillages.
It’s perfect for small apartments or indoor spaces where cleanliness is a priority.
3. Simpler Routine and Less Water Use
Hydroponic growth of calla lilies requires less frequent watering, as water levels can be visually monitored easily.
You also tend to use less water overall since the same water can be refreshed and recycled regularly.
4. Easy to Propagate and Share
Growing calla lilies in water makes propagation straightforward—dividing rhizomes and placing them in fresh water can produce new plants quickly.
It’s an enjoyable process to share start-up plants with friends or expand your collection.
Common Challenges and How to Avoid Them When Growing Calla Lilies in Water
While calla lilies can be grown in water successfully, some challenges come with this method.
Knowing these pitfalls helps you keep your plants healthy and blooming beautifully.
1. Root Rot from Too Much Submersion
If the rhizomes are fully submerged or water is stagnant, root rot can occur.
Make sure the rhizomes rest just above the water with roots dipping in, and change the water often.
2. Algae Buildup in Water
Algae can cloud the water and compete with the plant for nutrients.
Changing water weekly and cleaning your container regularly keeps algae under control.
3. Nutrient Deficiency Without Fertilizer
Simply using plain water won’t provide enough nutrients, leading to yellowing leaves and fewer blooms.
Regularly add liquid fertilizer to maintain healthy growth.
4. Insufficient Light
If your calla lilies in water don’t get enough light, growth will slow and flowers may not develop.
Keep them near a bright window but out of harsh sunlight.
5. Temperature Stress
Extremes of temperature can harm calla lilies growing in water.
Avoid placing water containers near heat vents, cold windows, or drafty spots.
So, Can Calla Lilies Be Grown In Water?
Calla lilies can indeed be grown in water, thriving when given the right setup and care.
Their adaptable rhizomes allow roots to grow directly in water, and with proper nutrients, light, and water quality, they bloom beautifully.
Growing calla lilies in water not only offers a clean, space-saving option but also creates a stunning display of flowers and roots in clear containers.
With these tips and insights, you can confidently grow calla lilies in water and enjoy their elegant presence indoors year-round.
So go ahead and bring a bit of watery green elegance into your space with these charming flowers—they grow just fine in water!
