Position – Plant your climbing cactus in full sun. If your plant has to be in a partly shaded spot, ensure that the tips are always in the sun so that they can bloom. The cactus needs some support to grow on, unlike most other cactus species. So, plant it next to a fence or trellis, or add support. Plant them at least 2 metres apart from one another.
Size – Depending on the conditions, this cactus grows to a height of between 2 and 5 metres. The flower can grow up to 25 centimetres in diameter and 30 centimetres in length.
Soil Type – Dragon fruit plants grow in any well-draining soil because it doesn’t become waterlogged and it allows the roots to grow more easily. If possible, sandy soil with a pH of between 6 and 7 (slight acidic) is best.
Mulch – Mulch helps to add nutrients to the soil, keep weeds away, and retain moisture. Use 5 to 15 centimetres of organic mulch, but keep it 20 to 30 centimetres away from the actual plant to prevent it from rotting. Hay, wood chips, old leaves, or grass cuttings make great organic mulch.
Watering – Water your plant when the surface of the soil around it is dry to the touch. Water it until the soil is moist, not flooded or waterlogged. Twice a week should be sufficient if no rain.
