Can You Grow Dragon Fruit Cactus Inside?

Yes, you can grow dragon fruit cactus (Hylocereus undatus) indoors, but there are a few key factors to consider. The plant requires plenty of sunlight, ideally six to eight hours per day. If your home has a sunroom or a large window that receives adequate sunlight, then you can successfully grow dragon fruit cactus indoors. Some varieties that are suitable for indoor growing include ‘Edgar’s Baby,’ ‘Alice,’ ‘Seoul Kitchen,’ ‘Yellow Dragon Fruit,’ and ‘Zamorano.’

How to Grow Dragon Fruit Cactus Indoors

Sunlight

Sunlight is crucial for the growth of dragon fruit cactus. The plant needs six to eight hours of full sunlight per day to develop flowers and fruits. If you don’t have access to natural sunlight, you can use supplemental grow lights. Full-spectrum LED lights are recommended to mimic strong sunlight. Rotate the plant regularly to ensure all sides receive equal sun exposure.

Temperature

Maintaining the right temperature is important for the health of your dragon fruit cactus. Keep the plant in a room with temperatures between 65 and 85 F. Avoid exposing the plant to temperatures above 100 F or frost. During the winter, keep the plant away from cold windows to prevent damage.

Humidity

Dragon fruit cactus thrives in 30% to 50% room humidity. During the winter heating period, you can increase humidity by placing a humidity tray with pebbles nearby, using a room humidifier, or misting the plant from above.

Watering

Be cautious when watering your dragon fruit cactus, as it is sensitive to overwatering. Water the plant when the top of the soil feels dry during the active growing season in the summer. Reduce watering in the fall and winter to induce plant dormancy.

Air Circulation

Proper air circulation is essential for the health of your dragon fruit cactus. Trim and thin out the plant at least once a year to ensure good air circulation and prevent fungal growth.

Fertilizer

Fertilize your dragon fruit cactus about once a month with a low-nitrogen fertilizer during the summer growing season. Avoid using too much nitrogen, as it can lead to excessive vegetative growth.

Pruning and Maintenance

When pruning your plant, focus on cutting it back to a single stem or a few thicker stems as the main vines. Thin out smaller side branches to improve air circulation and promote better fruit quality and size.

Pollination

If your dragon fruit cactus is not self-fertile, you may need to cross-pollinate it by hand. Collect pollen from the flower of another dragon fruit cactus and gently transfer it to the stigma of the plant you want to pollinate. Remember to use a fresh cotton swab for each plant.

Container and Size

Choose a five-gallon container that is at least 10 to 12 inches deep with proper drainage holes for your dragon fruit cactus. Opt for a heavy material container like ceramic or terracotta to prevent tipping over due to the plant’s height.

Potting Soil and Drainage

Contrary to its name, dragon fruit cactus requires nutrient-rich, neutral to acidic potting soil, not cactus soil, as the latter lacks essential nutrients. Improve drainage by adding sand to the soil and placing pebbles, stones, or bark at the bottom of the container.

Potting and Repotting Dragon Fruit Cactus

Repot your dragon fruit cactus when it appears root-bound, typically after one year. Handle the tiny, hairy roots with care to avoid damage during repotting. If you have space, consider planting it in a larger container right away to minimize the need for frequent repotting.

Moving Dragon Fruit Cactus Outdoors for the Summer

Once the danger of frost has passed and daytime temperatures consistently stay above 70 F, you can move your plant outdoors to a patio, porch, or balcony. Bring it back inside when temperatures drop below 65 F to prevent damage. During hot summers, protect the plant from excessive heat and sun exposure.

In conclusion, growing dragon fruit cactus indoors is a rewarding experience that requires attention to detail and proper care. By following these tips and guidelines, you can successfully cultivate this exotic plant in your home. From sunlight and temperature requirements to watering and pollination techniques, we’ve covered everything you need to know to help your dragon fruit cactus thrive. So roll up your sleeves, grab your gardening tools, and get ready to enjoy the beauty and taste of homegrown dragon fruit!
