Air Purification: Like many indoor plants, Calla Lilies help clean the air and increase humidity.
If you love having color and life inside your home when it’s dull outside, growing Calla Lilies indoors is the perfect solution.
Understanding Calla Lilies
Before we begin, it’s important to understand what Calla Lilies are and how they behave. Despite their name, Calla Lilies (Zantedeschia spp.) aren’t true lilies. They are perennial plants native to southern Africa, prized for their unique blooms and long-lasting foliage.
- Botanical Name: Zantedeschia aethiopica
- Type: Tender perennial (grown as an annual in cold regions)
- Common Colors: White, pink, yellow, purple, orange, and even black varieties
- Blooming Period: Spring to summer outdoors, but can bloom indoors in winter with proper care
The Secret to Indoor Winter Blooms
The secret to getting Calla Lily to bloom indoors in winter lies in mimicking their natural environment while managing their growth cycle carefully.
Calla Lily need a rest period after flowering. Once that dormancy ends, they can be encouraged to bloom again, even when it’s cold outside.
Here’s how you can make it happen:
- Let the plant rest in late summer or fall. Stop watering after flowering, allowing foliage to yellow and die back.
- Store the rhizomes in a cool, dry place for about 8–10 weeks.
- Replant them indoors in fresh soil, place near light, and resume watering.
- Within 8–12 weeks, your Calla Lily should reward you with new growth and winter blooms.
What You’ll Need to Grow Calla Lily Indoors
Before you start, gather a few essentials to ensure success.
| Item | Purpose |
|---|---|
| Healthy Calla Lily rhizomes | The base of your plant; ensure they’re firm and disease-free |
| Pot with drainage holes | Prevents root rot and ensures healthy growth |
| Rich potting mix | A well-draining soil mix with compost or organic matter |
| Watering can | Helps maintain consistent soil moisture |
| Bright, sunny window or grow light | Provides essential light for photosynthesis |
| Balanced liquid fertilizer | Encourages strong blooms and lush foliage |
Step-by-Step Guide: How To Grow Calla Lily Indoors
Step 1: Choose Healthy Rhizomes
Start with firm, plump rhizomes (bulb-like roots). Avoid any that are soft or moldy. The healthier the rhizome, the stronger your indoor plant will be.
Step 2: Select the Right Pot
Choose a pot at least 8–10 inches deep with good drainage holes. Calla Lilies dislike sitting in soggy soil. If you want multiple plants, use a wide container so each rhizome has space to grow without crowding.
Step 3: Prepare the Soil
Calla Lilies thrive in moist but well-draining soil. A good mix includes:
- 2 parts potting soil
- 1 part peat moss or coco peat
- 1 part perlite or sand
This ensures the soil stays airy while retaining enough moisture.
Step 4: Plant the Rhizomes
- Fill your pot halfway with the prepared soil mix.
- Place the rhizome about 2 inches below the surface, with the growing tips facing upward.
- Cover gently and pat the soil lightly.
- Water thoroughly after planting.
Step 5: Provide the Right Light
Place your Calla Lily pot near a bright, indirect light source, a south or west-facing window works best. During short winter days, use a grow light for 10–12 hours daily to encourage blooms.
Step 6: Water Consistently
Keep the soil evenly moist, but never waterlogged. Too much water can rot the rhizome. Water when the top inch of soil feels dry. Calla Lily enjoys humidity, so occasional misting also helps.
Step 7: Maintain Warmth
Calla Lily prefer temperatures between 60–75°F (15–24°C). Keep them away from cold drafts or direct heat vents. Stable indoor warmth helps trigger winter blooming.
Step 8: Feed for Flower Power
Feed your plant every 2–3 weeks with a balanced liquid fertilizer (10-10-10) once shoots appear. Stop fertilizing when flowers start to fade to prepare for dormancy.

4. Fungal Spots
Cause: Excess humidity or poor air circulation.
Fix: Improve ventilation, avoid misting at night, and remove affected leaves.

Tips for Encouraging Winter Blooms
- Start your planting cycle in early fall so that Calla Lily bloom by mid or late winter.
- Rotate pots weekly for even light exposure.
- Maintain humidity using a small tray of pebbles and water beneath the pot.
- Trim spent blooms promptly to encourage continuous flowering.

Propagating Calla Lily Indoors
Propagation is simple and rewarding. After the plant completes its blooming cycle and enters dormancy:
Remove the rhizomes from the soil.
Gently divide them using a clean, sharp knife, ensure each section has a growing eye.
Store divisions in a dry, cool spot for a few weeks.
Replant them in new pots during the next growing season.
This method helps you grow multiple Calla Lilies from one plant, perfect for gifting or expanding your indoor collection.
Dormancy and Re-Blooming Cycle
Calla Lilies naturally go dormant after blooming. Here’s how to manage that cycle indoors:
- Once leaves yellow, reduce watering gradually.
- Let the plant rest for about 8–10 weeks in a cool, dark area (around 50°F or 10°C).
- When dormancy ends, repot with fresh soil, water lightly, and move it to a bright spot again.
- New shoots will appear soon, followed by fresh blooms.
This rest period is key to ensuring healthy flowering year after year.
