The rose or flower of Jamaica can be grown in tropical and subtropical climates, at an altitude above sea level from 0 to 1,400 meters, with temperatures of 22 to 25 º C, its highest germination is at 25 º C with an annual rainfall of 500 to 1,000 millimeters per year, in heavy or clay soils with permanent humidity.
It adapts well in different kinds of soils and even with low nutrient content (low fertility), but the most suitable are loamy soils, with moderate fertility, mainly in nitrogen to prevent the plant from overgrowing and to produce as many calyxes as possible. It is generally found on land with undulating or flat topography.
As for planting, in some cases it is customary to make seedbeds and then transplanted but it is advisable to do direct seeding, placing 3 to 5 seeds per posture, a thinning is done after germination if necessary. The most commonly used sowing distance is 90 cm between plants and 130 cm between rows or 1 x 1 meters between plants and between rows.
