Position your passionfruit vine in full sun with protection from strong winds. In colder climates, choose a spot in front of north facing wall to utilise to radiated heat. Passionfruit vines grow extensive root systems so ensure the spot you choose to plant has plenty of space, free from weeds, competing plants and grass.
They will also spread up to 10 metres squared so choose or build a structure that can accomodate it. Passionfruit vines can be trained to grow along your fence, on a wooden or wire trellis , or over an arbour. Just install some wire or mesh to support its tendrils. The best soil for passionfruit vines is rich in organic matter and well-drained with a pH of 5. The best time to plant a passionfruit vine is in the spring season. If your soil is poor you will get problems with wilt diseases, root rot and nematodes.
Heavy clay soils also cause problems with rot diseases. Watering: The root system of a passionfruit vine is small for the size of the plant it has to sustain.
Especially while a passionfruit is fruiting it needs a lot of water. It needs a very regular water supply at all times. However, passionfruit can't handle waterlogged soil. Make sure your site is free draining. If I can grow something from seed I will.
If I can grow something from the seed of store bought fruit, even better. Why spend money on a nursery plant if you don't need to? Growing passionfruit seeds is not hard. The seed just needs to be fresh. For some reason old seed takes a lot longer to germinate. So buy some nice passionfruit, separate half a dozen seeds from the pulp, and plant them as soon as possible. They take about ten to twenty days to germinate. If you buy your seed then it's likely older, so be prepared to wait.
Old passionfruit seeds can take months to germinate. The best way seems to be to just put them in the garden and leave them be, and eventually they come up.
Or not. There are some tricks like soaking the seeds in warm water first, and some people swear by vinegar. Others report their acidic soil seems to do the job. I believe in fresh seed. Whenever I used fresh seed it came up without problems.
Seeds of hybrid varieties do not grow true to type. If you live in a cooler climate the passionfruit you buy may be a hybrid variety. If you grow that seed you don't know what kind of fruit you will get. It will be nothing like the parent plant and probably not very nice. Find out what the fruit is that you buy, or buy the seed so you know what you are planting, or even buy a plant from a nursery.
Another reason for not growing passionfruit from seed is the high susceptibility of the purple varieties and the hybrids to the root disease Fusarium wilt. Luckily, resistant root stocks exist flavicarpa varieties. If Fusarium wilt is a problem in your soil, and if you need to grow susceptible varieties because of your cool climate, then you may want to invest in a grafted plant from a nursery.
Ah, it's nice to live in the true tropics. All tropical passionfruits are reasonably resistant to Fusarium wilt and they are also more resistant to nematodes, another problem when growing passionfruit.
You can plant out your seedlings when they are about eight inches high 20 cm. If you wait too long and they are much bigger than that, prune them back as you plant them out. It helps reduce moisture loss while the root system settles in. Make sure that whatever support you have in mind is strong enough for the vine. They do get huge and heavy pretty quickly and need something sturdy. Also be aware that a vigorously growing passionfruit will climb over any- and everything it can reach and can quickly smother plants.
Make your own life easier by growing passionfruit away from other shrubs and trees. Over fertilising with a high nitrogen fertiliser can cause flowers to drop and prevent fruit from forming. If you've planted the vine in the correct position and you're still not getting flowers once established it's likely not getting the nutrients it needs.
Passionfruit vine hopper, also known as fluffy bum due to the appearance of its young, can attack vines and may lead to fruit or flower drop. These can be squashed or hosed off.
Juvenile fluffy bums can be treated with a garden spray such as a pyrethrum-based insecticide apply according to label instructions. Vines may also be attacked by scale. Use a horticultural spray oil to deal with scale. Fruit colour at ripening can be variable and some ripe fruit may not be highly coloured.
If green fruit drops to the ground it is always worth tasting it to see if it is ripe. Ripe fruit left on the ground may get sun burnt so regularly collect fruit.
