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.
Dragon Fruit do not like temperatures below 2degrees, please cover with frost cover or greenhouse plastic if planting in a cold climate.
Allow your dragon fruit to grow only one stem, and remove any additional growth.
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.
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.
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.
Fertilising:
During the growing season, the hotter months, give your dragon fruit some fertiliser every month. Alternatively, you can feed them once in spring and once after the plant has finished fruiting. Then, in winter, stop feeding the plant. A water-soluble fertiliser (like a 20-20-20) is perfect for dragon fruits.
Pruning:
Ensure only one stem grows, you can remove any others using a clean, sharp knife to make slanted cuts. Dispose of the offcuts properly as they will quickly grow and become weeds. You can also use these cuttings to grow more dragon fruit.
Once established the best time to prune is straight after fruiting, early in the morning.
Harvesting:
Dragon fruit plants produce fruit from February to May. Pick fruits that are evenly coloured about 30-40 days from the first sign of fruit.
The flesh should give slightly under gentle pressure. If they are soft or have a dry, shrivelled stem, they are overripe. They do continue to ripen after they have been plucked from the plant. So, if they are very firm when picked, leave them for a few days to ripen.
Depending on the climate it can take 2-3 years to fruit. Each season the fruit will be larger and more plentiful
