How to Plant Dragon Flower Fruit

Dig a hole that is 3 to 4 times the size of your dragon fruit plant's rootball. Repeat this step for each plant you want to grow. Space the holes 6 feet apart to allow ample space to grow. If you want to start dragon fruit plants from seed, break up the soil in the area where you want to plant the seeds and place them to a depth of 6 to 8 inches.

Add manure or compost to fertilize the soil in the holes you created for each dragon fruit plant. A 1-inch layer over the surface of the hole and mixed in well with the soil beneath provides enough nutrients to help the plant begin growing.

Give the dragon fruit plant support by putting up a ladder trellis or an arch next to each plant. Alternatively, plant your dragon fruit plants or seeds by a fence or some other object that the vines can grab onto as the plant grows.

Water the dragon fruit two to three times weekly to until you determine the plant's watering needs for your region. Keep the same routine as long as the plant continues to grow and does not look wilted. As a cactus, too much water can harm the dragon fruit plant and keep it from producing fruit or flowers.

Cover the plant with a blanket if your region gets a frost advisory. While dragon fruit plants can survive some frost, they will die from prolonged exposure and it is best to prevent all exposure if possible.
