Description
The purple passion fruit is most suited to upper midland and highlands (1,100 to 2,500m above sea level). It has superior fruits of 4 to 5cm in diameter with an aromatic flavor.
Yellow passion is most suited to the coastal lowlands. It is more vigorous and has a larger fruit of 5 to 7cm. It is more acidic and used for juice extraction.
Yellow passion fruit is resistant to Fusarium wilt and tolerant to Phytophthora blight, nematodes, and brown spots. It is used as rootstock for purple passion fruit.
Passion fruits grow on many soil types but do best in light to heavy sandy loams with a pH of 6.0 to 6.5. Excellent drainage is necessary. Also, the soil should be rich in organic matter and low in salts. If the soil is too acidic, lime must be applied. Since the vines are shallow-rooted, they need a thick layer of organic mulch.
