Selecting a Planting Site To successfully grow your own dragon fruit plant, you need a location with well-drained soil in full sun to partial shade and ample space. This is a large, heavy cactus with a spreading habit and long stems. Make sure to plant it 15 to 25 feet away from your home and other structures, trees, and electrical lines. Spacing, Depth, and Support Dig a hole that is 3 to 4 times in diameter and 3 times as deep as the nursery container (this loosens up the soil and aids in root development). Refill the hole with enough soil so that when you place the plant in the hole, it is at the same level as it was in the container.
