Fertiliser for Passion Fruit in NZ

Hello, and welcome! Few fruits have a flavour as unique and delicious as a passion fruit. Their tangy, sweet flavour is perfect for desserts and drinks, and they’re a fantastic addition to any garden. I’ve grown passion fruit vines for years, and I’ve learned that a little bit of know-how and the right feed can make all the difference to a bumper crop.

The Best Start for a Passion Fruit Vine

Passion fruit vines are subtropical and thrive in a warm, sunny spot that's sheltered from the wind. They need excellent drainage and a soil rich in organic matter. They also need a structure to climb, whether it’s a trellis, a fence, or a sheltered wall. The best time to plant them in New Zealand is from mid-spring to mid-summer, when the soil is warm and the risk of frost has passed.   

From my experience, the secret to a great passion fruit vine is a good start. I recommend digging in plenty of organic matter like compost before planting. If your soil is too acidic, you can add some lime to bring the pH up to a range of 6.5-7.5, which is perfect for passion fruit.   

When and How to Fertilise Passion Fruit

Passion fruit vines are heavy feeders and require a regular supply of nutrients throughout the spring and summer growing season. They need a fertiliser that's rich in   

Potassium to help with flowering and fruiting, but not too high in Nitrogen, as this can encourage a lot of leafy growth at the expense of fruit.   

I have always found a complete liquid feed to be the best way to deliver these nutrients quickly. LiquidGold™ Dual-Mix Super Feed is an ideal choice because its formula contains a full range of macro and micro-nutrients in a soluble form. It’s a complete feed that provides everything your vine needs to produce abundant, juicy fruit.   

How to Use LiquidGold™ Dual-Mix Super Feed on Passion Fruit:

  • Mix PART A and PART B from one sachet into 10L of water.
  • Apply the solution to the root zone of your vine every few weeks during the spring and summer. This is especially important when the fruit are approaching maturity, as a lack of water can cause them to shrivel and fall early.   

FAQ: How to Grow Great Passion Fruit

Why is my passion fruit vine not producing fruit?

This is a common question, and it's often caused by poor pollination or a lack of water at the time of fruit set. Passion fruit flowers are often pollinated by bees, so a lack of bees can be a factor. You can also try hand-pollinating the flowers with a small brush.   

Should I prune my passion fruit vine?

Pruning is essential for a healthy passion fruit vine. I recommend pruning in early spring to stimulate new growth. You should cut the vines back by about a third and remove any weak, dead, or criss-crossing vines to improve air circulation and reduce the risk of disease.
