Where is giant granadilla passion grown?

 Giant granadilla is grown in several regions across Kenya, particularly in areas with favorable climatic and soil conditions. But which are these areas? Granadilla is grown in regions such as Muranga, Kiambu, Nyeri, Nakuru, Uasin Gishu, Embu, Meru and Kakamega counties.

This giant passion thrives best in tropical climates where there is regular and well distributed rainfall of about 1,000- 2,000mm annually. For areas where the rainfall is below the expected, then irrigation would come in as a good substitute so as to help in the plant’s growth and fruit development. The plant prefers well drained sandy loam soils that have a pH range of 6.0 to 7.5 and that are well drained.


Giant granadilla can be propagated through seeds, cuttings, or grafting.


For commercial farmers, a spacing of 4 metres apart with holes of 60 by 60cm will be ideal so as to allow sufficient room for growth and air circulation. Spacing adequately will help prevent disease spread on your plants while ensuring they receive enough sunlight.


Just like other passion varieties, giant granadilla is also a climbing vine. Its vines are vigorous growers and need sturdy support structures to manage their growth and maximize fruit production. It is important to construct strong trellises or arbours for the vines to climb. Properly trellising your granadilla vines will ensure you have a maximum production due to a number of factors that I have outlined in this article.
