How to Grow Passion Fruit Vines

Passion fruit prefer fertile well drained soil in a sunny location. Freezes will generally only damage new growth but the vine tends to sprout back with vigor the following year. With regular watering a vine can be kept flowering and fruiting almost continuously. It is not uncommon for passiflora to produce their first year.  Water requirement is high when fruits are approaching maturity. If soil is dry, fruits may shrivel and fall prematurely. Fertilizer (10-5-20 NPK) should be applied at the rate of 3 lbs (1.36 kg) per plant 4 times a year, under normal conditions. Horizontal trellises have cross-pieces at the top of each post with 2-4 wires strung horizontally 60 cm (2 ft.) apart along the top of each cross-piece. Vertical trellises consist of heavy posts without cross-pieces, with 2 or 3 wires strung along the row like barbed wire fencing, attached to the posts from the top down at intervals about 30-40 cm (12-16 in.) apart. Trellis wires should be No. 9 or 10 galvanized steel. The posts need to be stout enough to withstand the weight of the vines throughout a season that normally includes the buffeting of strong winds. Ideally they should be long enough to provide a trellis height of 1.5 m (5 ft.), with 45-75 cm (18-30 in.) in the ground. Trellis rows should be oriented north-south for maximum exposure to sunlight, and the vines should be allowed to grow together along the trellises to promote cross-pollination. But if you dont have a trellis a tree will work just as well, requiring that you only trim the vine back every spring to promote new growth.
