Agro-ecological zones
Purple passion fruit does well in the upper midland to upper highland zones. Yellow passion fruits do well in the lower midland and lowland zones.
Altitude
The most suitable altitude for passion fruit production ranges from 1,200 - 2,000 Meters above Sea Level
Temperature
Optimum temperature for the production of purple and yellow passion fruit is between 18 °c to25°c and 25°c to 30° respectively.
Rainfall
A well distributed rainfall of 900mm to 2000mm per year is suitable for passion fruit production. Excess rainfall causes poor fruit set and encourages diseases.
Soils
Passion fruit plants will grow on a wide variety of soils, which should be reasonably deep and fertile. A soil pH range of 5.5 - 6.5 is best. In high rainfall areas, the soils should be well drained as plants will not withstand water logging or flooding for any considerable period.
Suitable Growing Areas
Purple passion fruit can be grown in Thika, Kisii, Nyeri, Kiambu, Nakuru, Kakamega, Murang´a, Embu, Vihiga, Nyamira, Meru, Trans-nzoia, Bungoma, Siaya, Keiyo, Nandi and Uasin gishu.
