Passionfruit is a delicious fruit that is easy and rewarding to grow and highly productive. These evergreen vines are prolific fruiters with most fruit production in warm weather particularly from summer to early autumn. Ripe fruit may colour and fall to the ground. Over ripe fruit may develop a shriveled skin. Tasting fruit is a good way to determine ripeness.
As well as the popular black passionfruit including the self-fertile variety ‘Nellie Kelly’, which grows in all but the coldest zones, there are other types including ‘Panama Gold’, ‘Panama Red’, ‘Pandora’ and granadilla, which are best suited to warm climates. These warm climate passionfruit types may need cross pollination for fruit formation (plant two vines). Check pollination requirements with your local hardware or garden centres. Banana passionfruit, which were the favoured passionfruit for cold zones, are now considered weedy and should not be planted.
Passionfruit are usually sold as grafted potted plants. Grafting makes the vine more tolerant of poor soil and cooler climate conditions.
Plant passionfruit vines at any time (but avoid extremely hot or cold conditions). At planting time and to reduce transplant stress, water with Seasol or Seasol GOLD. Before planting improve soil by digging in well-rotted manure or compost or for a no dig option use Seasol Liquid Compost.
Train passionfruit vines against a vertical surface such as a wall or fence. Vines may need to be replaced every five years as they become less productive
Aspect All passionfruit vines need a bright, sunny location with shelter from strong winds. Ideally they should have sun from the morning onwards but can tolerate a little afternoon shade especially in summer and should be protected from cold and frost.
Soil Passionfruit grow in a wide range of soils but grow best with good drainage in deep, fertile soils. Keep soil well mulched.
Climate Passionfruit does best in warm, frost-free climates where fruiting usually occurs within six months of planting but vines can take up to 18 months in cold temperate zones to produce fruit. Some varieties require a subtropical to tropical climate to grow well.
