• Climbing Growth for Unique Displays – Unlike many cacti, this species has long, vining stems that can be trained to climb trellises, walls, or other supports.
• Drought-Tolerant and Low Maintenance – This plant thrives in warm, dry climates and requires minimal watering, making it perfect for those who want an easy-care addition to their garden.

What Makes This Cactus Unique?

Dragon fruit cacti are distinct from other cacti because of their rapid growth and ability to climb. Unlike barrel cacti or columnar cacti, Selenicereus undatus has long, segmented stems that branch out in all directions, creating a jungle-like appearance. It’s also one of the few cacti that produce an edible fruit highly valued in health-conscious diets worldwide.

Unlike some other night-blooming cacti, which may only bloom once in a long while, this species can flower multiple times in a season under ideal conditions. This means you get more opportunities to witness its stunning blooms and, of course, enjoy its delicious fruit.

Growing and Caring for Your Selenicereus undatus

Light Requirements

Your Dragon Fruit Cactus loves bright, indirect sunlight. If grown outdoors, it should be placed in a location with filtered sun or partial shade in extremely hot climates. Indoors, a south-facing window or a grow light can help it thrive.

Watering Needs

While it is drought-tolerant, this cactus benefits from occasional deep watering. Water when the soil is dry to the touch, but avoid letting it sit in standing water, as this can lead to root rot.

Soil and Potting

This plant prefers well-draining, sandy soil. A cactus or succulent mix with added perlite or sand works best. If growing in a pot, make sure it has drainage holes to prevent excess moisture buildup.

Temperature and Humidity

As a tropical cactus, Selenicereus undatus enjoys warm temperatures between 65–85°F (18–29°C). It can tolerate brief drops in temperature but should be brought indoors or protected from frost in cooler climates.

Fertilizing for Growth and Fruit Production

To encourage healthy growth and fruiting, use a balanced, slow-release fertilizer during the growing season (spring and summer). A fertilizer rich in phosphorus and potassium can help promote more flowering and fruit production.

Pruning and Support

Since this cactus is a climbing species, providing a trellis or some other form of support will help guide its growth. You can prune it as needed to control its size and encourage more branching.

Harvesting and Enjoying Your Own Dragon Fruit

If you’re growing Selenicereus undatus for its fruit, you’ll want to keep an eye on its blooms. After pollination (either naturally by nocturnal pollinators or manually by hand), the flowers will give way to developing dragon fruits. These typically take 30-50 days to mature.

You’ll know your dragon fruit is ready to harvest when:

• The skin turns bright pink or red.
• The fruit feels slightly soft when pressed.
• The scales on the fruit begin to spread outward.

To harvest, simply twist the fruit off the plant or cut it with a sharp knife. Once harvested, you can enjoy the fruit fresh, blended into smoothies, added to fruit salads, or used in desserts.
