The Care of Dragonfruit Plants

Also known as night-blooming cereus or strawberry pear, dragonfruit (Hylocereus undatus) is a climbing cactus that may grow to a length of up to 20 feet. The succulent is cultivated both for its remarkable fragrant blooms, which open at night, and for its exotic pink skinned, white fleshed fruits.
  1. Location

    • The exact origin of dragonfruit is unknown, although it is believed to be from the West Indies, the Carribbean basin and parts of Central and South America. The cactus does best when grown outdoors in a subtropical or tropical climate. The cactus can tolerate temperatures as high as 104 F, but the plant may die during prolonged periods of frost. Dragonfruit prefers full sunlight, although it can benefit from partial shade in tropical climates.

    Soil

    • Dragonfruit isn't especially picky about soil, and may be grown in sandy soils as well as in heavier clay soils. For best results, use a well-draining soil mixture that has been enhanced with generous amounts of organic material. Water regularly from spring until late summer, keeping the soil just slightly moist at all times. The soil should never become completely "bone dry." Fertilize every moth or so with a balanced liquid fertilizer to aid flower and fruit production.

    Dormancy

    • Reduce watering in late August to about once a week or so, once nighttime temperatures start to consistently drop to 50 F or lower. In January or February, stop watering altogether for an entire month to allow the plant to undergo winter dormancy. The plant requires this period of rest in order to flower again. Water the plant on a regular basis again in March. Flowers should occur six to eight weeks after watering is resumed.

    Propagation

    • Dragonfruit may be propagated by stem cuttings, or more challengingly, by seeds sown in the spring. Root cuttings in a moist, well draining medium and move to a permanent position once the plant has developed roots. The tiny black seeds of the dragonfruit plant do best when sown in a well-draining compost. Seeds should germinate in 14 to 28 days at a temperature between 64.4 to 69 F. Cover seeds with a fine layer of soil to help aid germination.
