Can You Grow Wax Begonias Inside?

Yes, you can definitely grow wax begonias indoors with the right conditions. These plants are relatively low-maintenance and can provide bright indoor color during their flowering season. To successfully grow wax begonias indoors, it’s important to provide them with the right environment and care.

How to Grow Wax Begonia Indoors

Here are some essential tips for growing wax begonias indoors:

Sunlight

Bronze-leaved varieties of begonias tend to tolerate harsh sun better than green-leaved varieties.
When growing them indoors as potted plants, place wax begonias in a spot with bright, indirect light near a window. East-, west-, or south-facing windows are ideal for providing sufficient light.

Artificial Light

If natural light is limited, you can use artificial lights to supplement the light requirements of wax begonias.
Opt for a light that includes a mix of warm and cool colors to promote healthy foliage and flower production.

Temperature and Humidity

Wax begonias thrive in average to warm temperatures above 60 degrees Fahrenheit.
Ensure proper air circulation to prevent fungal diseases, especially during dry seasons.

Watering

Water indoor wax begonias when the top 1/2 inch of soil dries out.
Avoid overwatering to prevent root rot, and ensure the pot has proper drainage.

Air Circulation

Good air circulation is essential for healthy growth. Consider placing the plant near a fan to mimic outdoor breezes.

Fertilizer

Feed indoor wax begonias with liquid fertilizer weekly or biweekly during the growing season.
Use a high phosphorous fertilizer every third or fourth feeding to promote flowering.

Pruning and Maintenance

Regularly prune old blooms and yellowing leaves to keep the plant looking vibrant.
Trim the stems to encourage bushier growth and a fuller plant.

Container and Size

Choose a slightly smaller pot compared to the size of your plant to encourage root-bound growth.

Potting Soil and Drainage

Use a general-purpose peat-based potting mix amended with perlite for proper drainage.

Potting and Repotting

Consider taking cuttings from older plants rather than repotting.
If repotting is necessary, do so in the spring using fresh, fast-draining soil.

Moving Wax Begonia Outdoors for the Summer

During the warmer months, you can move potted wax begonias outdoors to give them plenty of sunlight and air circulation. Follow these considerations when transitioning your plants outdoors:

Considerations

Wait until temperatures consistently reach 60 degrees Fahrenheit before moving plants outdoors.
Monitor soil moisture and adjust watering accordingly.
Bring plants back indoors before temperatures drop below 60 degrees in the fall.

In conclusion, wax begonias can thrive as indoor plants with the right care and attention. By providing them with proper lighting, temperature, water, and maintenance, you can enjoy these colorful beauties year-round. Whether you’re a beginner or experienced gardener, growing wax begonias indoors can be a rewarding experience. So, bring some natural cheer into your living space with these lovely plants!
