Grow passion fruit vine in locations that receive partial or filtered sun, in regions of the country that the weather is extremely hot. Cooler regions can grow passion fruit vine in the full sun, for best results.
Install a strong trellis or arbor one foot away from the passion fruit for the vine to latch onto. Plant the vine next to a chain link fence, if one is available. Passion fruit vine will use anything it can as a support for its tendrils. Place the legs of the trellis or arbor at least one foot deep within the soil and pack the soil firmly around them, to make it stable.
Consider the passion fruit vine’s growth habit when selecting a location to for it. Its aggressive growth will quickly take over an area if not contained. Grow the vine in an area where it will not interfere with other vegetation or structures.
Plant the vine in a rich soil that drains very well. Amend sandy soils with compost, working it into the soil approximately 8 inches. Add lime to soils that are too acidic.
Lay mulch around the base of the passion fruit vine to protect the roots in winter, help the soil retain moisture and cut down on grass and weed growth. Apply a fresh coat of mulch yearly.
Water the vine regularly to keep the planting site moist, but not flooded. Keep the soil moist, especially when the fruits are about to mature or they may fall off prematurely.
Fertilize the passion fruit vine in every three months. Use a 10-5-20 granular fertilizer at a rate of 3 pounds per plant. Water the fertilizer in well after application.
Prune the vine after harvesting the fruit in warmer areas of the U.S. Prune in early spring, in cooler regions. Cut the vine back by one third. Trim the vine to keep its size under control and to remove any dead or damaged wood.
Protect the passion fruit vine from frost damage by covering as much of it as you can with blankets or shoving dead leaves between the vines. Cover the roots with a thick layer of mulch or additional leaves for protection. Passion fruit vines will often sprout back after being frozen to the ground.
