The passion fruit vine is a perennial plant that is tropical to sub-tropical locations, with only a few cultivars able to withstand slight frosts. The plant is woody and climbs by way of tendrils. The vines will climb trees, over rocks or whatever is available. For the home garden, erecting trellises and training the vine is important if you wish to eat the fruit. The fruit is grown commercially in Hawaii, South Africa, Brazil and Australia. There are purple and yellow passion fruit which can be eaten out of hand, or made into juice, jams and pies.
Choose a location that has morning sun to some afternoon shade. The area must be able to drain well and water should not pool after a heavy rain.
Install a trellis system for your passion fruit vine to climb. Trellis systems--like those used for grape vines--work well. Use wooden posts in whatever trellis system you decide to build as the posts will attract carpenter bees and these bees will pollinate the flowers to set fruit.
Dig a hole twice the diameter of the root ball. The depth of the hole should be the same as the root ball. If you are using a trellis system like you would for a grape vine, use an 8- or 12-foot center. Place the planting hole in the front, center of a flat trellis system.
Clean the dug-out soil of all weeds, grass and stones. Amend the soil to a mixture of one part compost and two parts original soil.
Place the root ball in the planting hole and fill in around it with amended soil. Saturate the soil in order to compact it around the roots and add more soil if settling has occurred. The soil should be level with the surrounding ground.
Apply a balanced fertilizer with micronutrients once you start to see new growth. Follow manufacturer’s directions for the amount to use per size and age of the vine.
Spread a 3-inch layer of mulch in a 3-foot diameter around the plant, keeping it 6 inches from the main trunk of the vine. The mulch will keep the area weed-free and help to retain moisture.
