Feed and Water
Keep hungry passionfruit vines well watered (especially when there’s little rain) and fed from spring to autumn. Use Yates Thrive Natural Citrus & Fruit Organic Based Pelletised Plant Food nourish your plants. Water plants well before adding fertiliser then spread it around the base of the stem and along the area where the roots are growing. Be sure to remove any weeds that start to grow near your plant by hand.
Look out for suckers
Many passionfruit are grafted plants. From time to time the root system your vine is grafted on tostarts to grow. It can out grow the productive vine and cause it to become weedy. Always remove suckers from below the graft area and avoid damaging the root system as this can encourage suckering.
Pruning your passionfruit
Passionfruit vines don’t require pruning to encourage fruiting, but they may need a trim from time to time to remove overgrown growth. They can become quite heavy so ensure the area its climbing can bear the weight. We belive the best time to prune is in spring as new growth resumes. Do avoid removing main stems, just cut back unwanted twining stems.
You can expect fruit about 18 months after planting. If your vine is not fruiting after this time, it may be due to one of the following reasons.
It needs more water. Passionfruit vines are heavy feeders and need plenty of water. A dry plant will not produce fruit, so ensure the soil is moist.
Heavy rain during the flowering phase can ruin the viability of the pollen and cause a lack of bees for pollination. You can self pollinate using a small paintbrush or toothbrush to transfer pollen from one flower to another.
Overfertilising results in flowers but no fruit. Passionfruit usually only needs fertilising twice a year, after pruning and again after fruiting.
Yates Thrive Citrus Plant Food is a fertiliser high in nitrogen, this promotes plenty of passionfruit leaf growth at the expense of fruit and flowers.
5 hours of sunshine. Passionfruit require at least five hours of direct sunshine a day. They should be planted in a sunny spot with no trees or competitive roots.
Passionfruit fruit is empty?
This can be caused by overfeeding or an result of weak seedlings. Follow the fertilising guide on pack and if the issue continues it may mean that you need to start again from scratch.
Passionfruit is falling off before it’s mature?
This can be caused by extreme cold weather or the plant not getting enough water.
If the soil around your plant is dry the fruit may shrivel and fall prematurely. Be sure to water frequently in short intervals in dry times to keep it growing and healthy.
Storms can certainly play havoc when they hit, especially in the garden. If your passionfruit has dropped its fruit due to a storm and the fruit is still green, then unfortunately they are unlikely to sweeten up.
You would normally pick the fruit when it has changed from green to purple thus allowing as much time as possible for the fruit to mature and ripen on the vine.
All is not lost, your vine will produce again next year, so come spring, fertilise the vine with some Yates Dynamic Lifter Soil Improver & Plant Fertiliser to encourage flowering and fruiting. Give ample moisture to the vine during the hot summer months and next summer/autumn your vine will reward you with lots of delicious sweet fruits.
