Native to South America, the Passion fruit vine is a perennial tropical or semi-tropical vine that thrives in zone 8 to 10. Two main varieties of the vine can be found throughout the warmer regions of the world, the purple flowering cultivar and the yellow flowering cultivar. The purple variety is more tolerant to cold than the yellow flowering variety. This vine grows to 20 feet tall and bears large, unique flowers. The flowers are fragrant and bloom throughout the summer. When conditions are right, the vine will form small oval berries in the early fall that can be eaten.
Choose a location in your garden that receives at least six hours of sunlight but is protected from the intense afternoon sun, particularly if you live in a hot climate. Plant your passion fruit vine in the spring as temperatures begin to rise and the ground can be worked.
Loosen the soil to a depth of 18 inches with a shovel, breaking up any large clumps of dirt. Amend the soil with compost. Although, according to Rare Fruit Growers of California, passion fruit vines will grow in many types of soil, they need excellent drainage and do better in soils rich in organic matter.
Plant your passion fruit vine at the same depth it had been growing in its previous container. Gently break up the roots or score the root ball to avoid your plant being root bound and to promote vigorous root growth.
Provide a trellis or another sturdy growing structure on which your passion fruit vine can grow.
Spread a thick layer of mulch around your passion fruit vine. Passion fruit vines have a shallow root system and the mulch will regulate the soil temperature and retain moisture.
Water the soil to remove any air pockets that may be around the roots. Keep the soil moist, but not wet, the first year to encourage a healthy root system.
Fertilize your passion fruit vine during the growing season. According to the University of Florida, you should fertilize your passion fruit vine with a general purpose, balanced fertilizer as soon as new growth appears in the early spring and then again at four to six week intervals. Do not over fertilize as this will burn your plant's roots.
Prune your passion fruit vine to size in the late winter while the vine is dormant. Remove any dead or damaged vines. Always use clean and sharp garden shears.
