Why Grow Calla Lily in Water?
If you’re wondering why you should learn how to grow calla lily in water, there are several great reasons:
1. It’s Mess-Free and Easy
Growing calla lily in water eliminates the mess that comes with soil.
You won’t have to worry about soil spilling or pests creeping in.
Plus, it’s a fantastic option for apartments or homes without outdoor garden space.
2. You Can Watch Roots Grow
One of the most satisfying parts of growing calla lily in water is watching the roots develop and flourish.
It’s a fun and educational experience, especially if you love seeing the growth process up close.
3. Promotes Healthy Bulbs
Calla lilies often do well when grown hydroponically—in water—because the bulbs stay moist but not waterlogged.
This helps reduce the risk of bulb rot, improving the overall health of your plant.
4. Elegant Indoor Decor
A clear glass vase or container with a calla lily bulb growing in water creates a chic and modern look.
It’s a beautiful way to add nature and style to your home decor without too much effort.
How to Grow Calla Lily in Water: Step-by-Step
Now that you’re convinced of the perks, here’s how to grow calla lily in water easily and successfully.
1. Choose Healthy Calla Lily Bulbs
Start by selecting firm, plump bulbs with no signs of mold or damage.
Healthy bulbs are crucial because they store the energy your calla lily needs to sprout and bloom.
If you can, buy bulbs labeled for indoor planting or specifically suited for hydroponic growth.
2. Prepare the Container
Pick a clear glass vase or container that’s tall enough to hold the bulb above the water while allowing its roots to dangle freely.
Glass is ideal because you can monitor root growth and water clarity.
Avoid wide shallow containers, as they might submerge too much of the bulb and cause rot.
3. Add Clean Water
Fill the container with room temperature, clean water about halfway up the bulb.
Don’t submerge the entire bulb; only the base where roots will develop should be in the water.
Distilled or filtered water is better than tap water since it reduces chemicals that might hinder growth.
4. Place the Bulb Correctly
Set the calla lily bulb in the container with the pointed end facing upward.
Make sure the bottom of the bulb just touches the water surface.
This positioning encourages root growth downward into the water and leaf growth upward into the air.
5. Position in a Bright Spot
Calla lilies need bright, indirect sunlight to thrive in water.
Place your container near a window with filtered light or in a room with plenty of natural brightness.
Avoid direct sun, as it may overheat the water and damage the bulb.
6. Change Water Regularly
Refresh the water every 7 to 10 days to prevent stagnation, algae growth, or bacterial buildup.
Use clean, room temperature water each time to keep the bulb healthy.
7. Fertilize Occasionally
Since calla lilies grown in water don’t get nutrients from soil, add a few drops of liquid fertilizer every 4 weeks.
Use a balanced fertilizer, diluted to half strength.
This supplies essential nutrients and supports strong leaf and flower development.
8. Watch for Root and Leaf Growth
Within 2-3 weeks, you should see roots forming in the water and leaves sprouting from the bulb.
Healthy roots will appear white or light-colored and firm.
If roots look brown or slimy, change the water more often and remove any decayed parts.
Best Tips for Growing Calla Lily in Water Successfully
Even though growing calla lily in water is easy, a few insider tips can improve your success rate:
1. Use Room Temperature Water
Cold water can shock the bulb and slow growth.
Always use water that’s room temperature to encourage steady root development.
2. Avoid Overwatering the Bulb
Keep only the bottom of the bulb submerged.
Too much water coverage causes the bulb to rot.
If you notice softness or a foul smell, it’s a sign of rot—remove the affected parts immediately.
3. Provide Humidity
Calla lilies love humidity, so misting the leaves lightly every few days enhances their growth.
Alternatively, keep them in a room with higher humidity, like a kitchen or bathroom.
4. Prune Dying Leaves
Remove any yellowing or damaged leaves promptly.
This focuses the plant’s energy on new growth and prevents disease spread.
5. Repot for Longer Growth
After your calla lily has been growing in water for a couple of months, you can transplant it into soil for sustained growth and blooming.
Use well-draining potting soil rich in organic matter.
Alternatively, keep it in water but prepare for a shorter flowering period.
Common Challenges When Growing Calla Lily in Water and How to Fix Them
As with any plant-growing hobby, knowing how to handle problems can save your calla lily from failing.
1. Bulb Rot
If your bulb starts to soften and smell bad, it likely has rot.
Fix this by trimming off the rotted part with sterile scissors.
Change water more frequently and improve airflow around the plant.
2. Algae Growth in Water
Green water or algae on the container walls is common in water gardening.
Prevent this by keeping water changes regular and placing the container in indirect sunlight only.
Rinse the container thoroughly when you change the water.
3. No Root Development
Sometimes, bulbs can be slow to root.
Make sure the water is fresh, the bulb is only slightly touching the water, and the light isn’t too weak.
Try keeping the container warmer, as warmth encourages rooting.
4. Yellowing Leaves
Yellow leaves usually mean either too much water or not enough nutrients.
Check that the bulb isn’t submerged too deeply and add diluted fertilizer to the water.
So, How to Grow Calla Lily in Water?
Growing calla lily in water is a rewarding and straightforward process that starts with choosing healthy bulbs and placing them correctly in water.
By providing clean water, bright indirect light, occasional fertilizer, and regular care, you can enjoy stunning calla lily blooms without soil.
