Watering Calla Lilies Indoors and Outdoors
Based on my experience, watering is the most important part of calla lily care. These plants love moisture, but too much water can rot their rhizomes.
- Indoors: Water when the top inch of soil feels dry. Avoid overwatering.
- Outdoors: Water deeply once or twice a week, especially during dry spells.
- In containers: Ensure pots have good drainage to prevent water logging.
Soil Requirements for Calla Lilies
The right soil makes a huge difference in healthy blooms.
- Use a well-draining, fertile soil with plenty of organic compost.
- Indoors, a quality potting mix with peat and perlite works well.
- Outdoor soil should be loose, rich, and slightly acidic (pH 6.0–6.5).
Sunlight for Indoor and Outdoor Calla Lilies
From my garden to my living room window, I’ve learned that sunlight affects bloom quality.
- Indoors: Place near a bright, indirect light source like an east-facing window.
- Outdoors: Choose a spot with partial sunlight — morning sun and afternoon shade is ideal.
- Avoid harsh midday sunlight, especially in hot climates.
Humidity and Temperature Needs
Calla lilies enjoy warmth and moderate humidity.
- Ideal temperature range: 60°F to 75°F (15°C to 24°C).
- Indoors: Mist the leaves occasionally to increase humidity.
- Outdoors: In cold zones, dig up rhizomes before frost and store indoors for winter.
Fertilizing Calla Lilies Properly
To keep your calla lilies blooming strong:
- Use a balanced 10-10-10 fertilizer once a month during the growing season.
- Avoid over-fertilizing — too much nitrogen can cause lush leaves but no flowers.
- Stop feeding once the plant enters dormancy in late summer or fall.
How to Propagate Calla Lilies
Propagation is simple and a great way to grow more plants for free.
- Wait until fall when the foliage dies back.
- Gently dig up the rhizomes and separate them with a clean knife.
- Replant immediately or store in a cool, dry place until spring.
- Always label the varieties if you have more than one.
