Checking the Bulbs Regularly
As winter approaches, it’s crucial to monitor your calla lily bulbs regularly to ensure their well-being during dormancy. Here’s why regular bulb inspections are so important:
Prevent Rot and Disease: Inspecting bulbs allows you to identify and remove any infected or damaged ones. Early detection prevents the spread of rot or disease, protecting the health of your remaining bulbs.
Monitor Moisture Levels: Checking bulbs for moisture content ensures they’re not too wet or dry. Excessive moisture can lead to rot, while dryness can stunt growth. Adjust watering accordingly to maintain optimal conditions.
Detect Sprouting: Check bulbs for new growth or sprouts. If sprouting occurs prematurely, it’s important to remove the sprouts to prevent weakened bulbs and poor spring growth.
Steps to Check Calla Lily Bulbs:
- Gently lift the bulbs from storage and examine them for any signs of rot, mold, or physical damage.
- If you notice any issues, discard the affected bulbs to prevent the spread of problems.
- Check the moisture levels by squeezing the bulbs gently. They should be slightly firm but not bone dry.
- If the bulbs feel too wet, allow them to air dry in a well-ventilated area before returning them to storage.
- If the bulbs feel too dry, mist them with water or place them in a slightly damp environment.
Key Takeaways:
- Inspect calla lily bulbs regularly during storage to prevent rot and disease.
- Monitor moisture levels to ensure bulbs aren’t too wet or dry.
- Remove any infected or damaged bulbs promptly.
- Detect and remove sprouts prematurely to prevent weakened bulbs.
- Store bulbs in a cool, dark, and dry location.

FAQ
Q1: How do I prepare my calla lilies for winter if I live in a warm climate?
A1: In warmer climates (USDA zone 8 or higher), calla lilies may not require winterizing. However, it’s recommended to prune back foliage and stems to ground level and apply a layer of mulch around the base of the plant to protect the roots and tubers from cold temperatures.
Q2: How often should I water my calla lilies in the winter?
A2: Reduce watering frequency during the winter months, especially if your calla lilies are stored in a cool, dark place. Water the bulbs only when the soil is completely dry to the touch. Overwatering can lead to rot and disease.
Q3: Can I leave my calla lilies in the ground over the winter?
A3: In climates where the ground freezes (below USDA zone 8), it’s best to dig up and store calla lily bulbs indoors over the winter. In milder climates, you can leave the bulbs in the ground and protect them with a thick layer of mulch.
Q4: How do I store calla lily bulbs over the winter?
A4: Store calla lily bulbs in a cool, dark, and dry place with good ventilation. Optimal storage temperature is between 60 and 70 degrees Fahrenheit. Place the bulbs in beds or trays without touching each other. Label the bulbs for identification and check them periodically for signs of rot or pests.
Q5: When should I start preparing my calla lilies for winter?
A5: Begin preparing calla lilies for winter in late summer or early fall. Gradually reduce watering frequency and apply a layer of mulch around the base of the plants. Dig up and store the bulbs indoors in colder climates before the first frost.
