🌾 Sow directly in the garden — Dragon Fruit is not usually started indoors.
Since this plant requires frost-free conditions, do not wait for the last frost date; instead, move seedlings outdoors only after all danger of freezing has passed and temperatures remain consistently warm.
Soil, care & harvest
As a tropical vine, you should start dragon fruit seeds indoors well before your last frost date, as it cannot survive cold temperatures. Prepare a potting mix with a pH between 6.0 and 7.0. Sow the small seeds on the soil surface or barely cover them with vermiculite. Keep the medium moist but not soggy until germination occurs in 1 to 3 weeks.
Space your plants about 10 feet apart once they are established outdoors. Because these vines climb, you must provide a sturdy trellis or support structure immediately to guide their growth. Water deeply only when the soil has dried out between sessions, avoiding waterlogged roots. Apply a light mulch around the base to retain moisture and suppress weeds.
Watch for spider mites and mealybugs, which can be prevented by ensuring good air circulation and inspecting leaves regularly. Harvest the fruit when the skin turns yellowish with green spots; it is ready about 30 days after flowering. Cut the fruit from the vine carefully to avoid damaging the spines on the stem.
