Position – Plant your granadilla plant in a warm spot that is protected from strong winds. Train it against a trellis or fence and it will twist itself around the support.
Soil Type – Use a sandy loam soil with a pH of between 6.5 and 7.5 for the best results.
Dig a hole about 60 x 60 centimetres and enrich the soil with good organic compost and some bone meal. At Just Berry Plants, we provide volcanic rock dust, which would be sufficient to create an optimal environment. This deep soil prep is necessary for good root growth and to make sure that the soil has good drainage (granadilla plants are sensitive to wet soil conditions).
Water the potted plant before transplanting and then plant it at the same level in the ground as it was in the pot. Then, firm the soil around the plant.
Water – Water your plant very well every 2 to 3 days rather than a little every day.
Pruning – Prune the side shoots back to 60 centimetres from the ground twice a year after they have finished bearing fruit. Thin out the plant to prevent overcrowding and overlapping, and remove dead or diseased wood.
Fertilising – Fertilise your granadilla at the start of spring and after fruiting. The best fertiliser for a granadilla plant is 3.2.6.
Mulch – Keep the soil mulched with compost at all times to retain moisture, protect the plant’s roots from UV damage, and keep weeds at bay.
Harvesting – This plant bears fruit twice a year – a summer crop and a smaller winter crop. The first fruits will be ready about 6 to 9 months after planting. Pick the fruit when they are fully developed and light purple in colour. Let them ripen in your kitchen; they are ready to eat when they are dark purple, and the skin has started to shrivel.
