Wintering Begonias: Tips for Overwintering a Begonia in Cold Climates

As winter draws near, it’s time to start thinking about how to care for your beloved begonias during the colder months. These delicate plants require special attention in order to survive the harsh conditions of winter, especially if you live in a cold climate. In this article, we’ll provide you with some tips and tricks for overwintering your begonias and keeping them healthy until spring arrives.

Understanding Begonias

Begonias are popular houseplants known for their colorful blooms and attractive foliage. There are many different types of begonias, including tuberous, fibrous-rooted, and rhizomatous varieties. While they are relatively easy to care for during the growing season, begonias require extra attention during the winter months.

One important thing to know about begonias is that they are native to tropical and subtropical regions. This means that they prefer warm, humid environments and don’t tolerate cold temperatures well. In fact, most begonias can’t survive below 50°F (10°C).

Preparing Your Begonias for Winter

The first step in overwintering your begonias is to prepare them for the colder weather. Here are some things to keep in mind:

1. Time your transplanting carefully

If you plan to move your begonias indoors for the winter, it’s best to do so before the first frost. This will give them time to adjust to their new environment before the temperature drops too much.

2. Cut back on watering

During the winter months, begonias enter a period of dormancy where they require less water. Be sure to cut back on watering as the days get shorter and the temperature gets cooler.

3. Reduce fertilizer use

Like watering, you should also reduce the amount of fertilizer that you give your begonias during the winter. Too much fertilizer can actually damage the plant’s roots and leaves.

Choosing the Right Location

The next step in overwintering your begonias is to find the right location for them. Here are some things to consider:

1. Temperature

As we mentioned earlier, begonias can’t survive temperatures below 50°F (10°C). Make sure to keep your plants in a location that stays above this threshold.

2. Humidity

Begonias thrive in high humidity environments. If your home tends to be dry during the winter months, consider placing a humidifier near your plants or grouping them together to create their own microclimate.

3. Light

While begonias don’t require direct sunlight, they do need bright, indirect light in order to thrive. Place your plants in a location that receives plenty of natural light throughout the day.

Caring for Your Begonias During the Winter Months

Once your begonias are settled into their new location, there are a few things that you can do to ensure their health and wellbeing during the winter months:

1. Monitor the temperature

Make sure to keep an eye on the temperature in the room where your begonias are located. If it starts to drop too low, consider moving them to a warmer location.

2. Check for pests

Pests like spider mites and mealybugs can still pose a threat to your begonias during the winter months. Check your plants regularly for signs of infestation and treat them as needed.

3. Prune as needed

If your begonias start to become leggy or overgrown during the winter, consider pruning them back to encourage new growth in the spring.

Bringing Your Begonias Back Outdoors

As the weather starts to warm up in the spring, it’s time to start thinking about transitioning your begonias back outdoors. Here are some tips for making the transition:

1. Gradually increase light exposure

When you first bring your begonias back outdoors, they may not be used to the intensity of direct sunlight. Gradually increase their exposure to sunlight over a period of several weeks to avoid burning their leaves.

2. Resume regular watering and fertilizing

As your begonias start to grow again in the spring, resume regular watering and fertilizing according to their specific needs.

3. Repot as needed

If your begonias have outgrown their containers during the winter, consider repotting them in fresh soil in the spring.
