Position:
Plant in semi-sun or a dappled shade, the plant requires protection from the hot sun.
Soil:
Passiflora quadrangularis thrives in humus-rich, moist soil with good drainage. It should be planted in a spot with dappled shade to allow it to grow towards the sun. It prefers neutral soil and dislikes very acidic or alkaline conditions.
Watering:
The giant granadilla is sensitive to both water deficiency and excess.
When the plants are mature enough, reduce watering to twice a week if your garden receives less than 4 cm of water weekly. _
If planted in containers, the soil will dry out more quickly than in the garden, so it may require more frequent watering.
Mulching:
Add a thick layer of pine bark mulch, keeping it about 20 to 30 centimetres away from the tree trunk (any closer may cause excess moisture and damage the trunk). This will retain the moisture in the soil and will prevent weeds from taking over.
Fertilising:
Apply 1 teaspoon of our slow-release nitrogen-rich berry fertiliser every 4-5 months.
Pests and Diseases:
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control ) will assist in either prevention or after the fact. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (if overwatered) and fungal infections during wet periods.
Harvesting:
Harvesting the fruit a day or two before it becomes too ripe and falls off the tree, preventing it from smashing on the ground.
Pruning:
To promote healthy growth, it is recommended that the side shoots be pruned in late winter or spring, trimming them down to 3-4 buds. Heavily pruning will rejuvenate the plant.
