Bringing Your Mandevilla Indoors for the Winter

Mandevilla plants, with their trumpet-shaped flowers, aren't known for their cold hardiness. To ensure your plant survives the winter, bringing it indoors is crucial in most climates. Here's how:

1. Choosing the Right Spot:

Sunlight: Select a sunny location, ideally a south-facing window. At least 6 hours of sunlight daily is ideal.
Temperature: Maintain a temperature between 55-70°F (13-21°C). Avoid drafty areas near doors or windows.
Humidity: Mandevillas prefer higher humidity. Consider placing the pot on a pebble tray with water (ensure the bottom of the pot doesn't touch the water). Alternatively, you can group plants together or use a humidifier.

2. Pruning Your Mandevilla:

Before bringing your mandevilla indoors, prune it back by about one-third. This helps manage its size and encourages bushier growth in the spring. Use sharp, clean pruning shears to prevent disease.

3. Repotting (Optional):

If your mandevilla is root-bound (roots circling the pot), repot it into a slightly larger container with fresh, well-draining potting mix. This provides more space for root growth.

4. Watering and Fertilizing:

During the winter months, reduce watering significantly. Allow the top inch of soil to dry out before watering again. Avoid overwatering, which can lead to root rot. Stop fertilizing entirely during the winter dormancy period.

Protecting Your Mandevilla Outdoors (for Mild Climates)

If you live in a region with mild winters (rarely freezing temperatures), you might be able to protect your mandevilla outdoors.

1. Choose a Sheltered Location:

Place your mandevilla against a south-facing wall or under the protection of an overhang. This provides some insulation from cold winds and frost.

2. Mulching:

Apply a thick layer of mulch around the base of the plant to insulate the roots. This helps protect them from freezing temperatures.

3. Frost Protection:

On nights with predicted frost, cover your mandevilla with a frost cloth or blanket. Remove the covering during the day to allow for sunlight.

Troubleshooting Common Winter Problems

Q: My mandevilla is dropping leaves. What should I do?

A: Leaf drop can be due to several factors, including cold temperatures, low humidity, or underwatering. Check the temperature, humidity levels, and adjust your watering schedule accordingly.

Q: My mandevilla is developing yellowing leaves. What's wrong?

A: Yellowing leaves might indicate overwatering, poor drainage, or nutrient deficiencies. Check the soil moisture, ensure proper drainage, and consider repotting if necessary.

Spring Awakening

Once spring arrives and the threat of frost has passed, you can gradually acclimate your mandevilla to outdoor conditions. Start by placing it outdoors for a few hours each day, gradually increasing the exposure to sunlight.

By following these tips, you can ensure your mandevilla survives the winter and rewards you with a spectacular display of blooms the following spring! Remember to adapt these instructions to your specific climate and your mandevilla's needs. Happy gardening!
