Water Needs for Passion Fruit

Watering Tips

• During each watering, penetrate soil at least to the depth of the root zone. Avoid wetting plant foliage, because this may lead to subsequent fungal infections. In general, under-vine microsprinklers are the most efficient and effective water delivery mechanism. As the fruit reaches peak maturity, vines may need as much as 100 gallons of water per week. Consider applying a thin layer of mulch over the plant roots to help retain some of the soil moisture.

Soil Requirements

• Passion fruit thrives in fast-draining soil, such as sandy loam. Avoid planting this species in poorly drained soil, which frequently leads to root problems. Be advised, this species is highly susceptible to numerous soil diseases, such as collar rot. Consider using raised plant beds if soil drainage is not adequate. Passion fruit prefers slightly acidic soil with a pH between 6.5 and 7; however it will tolerate slightly more alkaline soils if the soil is amended with micronutrients.

Site Selection

• Passion fruit thrives in growing temperatures between 68 and 82 degrees Fahrenheit. It grows best in full sun within coastal locations and partial sun further inland, where sun tends to be drier and hotter. The purple passion fruit is better adapted to cooler temperature and can endure some frost-like conditions. The yellow passion fruit thrives in more tropical conditions and lower elevations. Both forms of passion fruit require some form of wind protection.

Average Life Span

• In general, passion fruit is a short-lived plant. Plants typically succumb to some form of root problem after a few years. This species is particularly susceptible to crown rot, fusarium wilt and nematode attack. Commercial passion fruit plants are expected to last between three and four years. Well cared for, properly irrigated plants placed in a good location with healthy soil may last as long as seven years. However, anticipate annual fruit yields to decline after about three years.
