Production Method:

This fruit variety thrives in a temperate climate. It is cultivated at elevations up to 550 meters, with an ideal annual temperature range between 13-16 °C, a minimum temperature tolerance of -5 °C, and a maximum of 35 °C. It exhibits a strong tendency toward periodicity, requiring a minimum cumulative temperature of 2284 °C and a maximum of 2572 °C, with an average daily temperature around 20 °C.

The annual rainfall should exceed 700 mm, with even distribution across the months. It grows best in soils with a pH between 5 and 7, rich in nutrients, having a loamy-humus texture and a groundwater level that remains sufficiently low. It is crucial that relative humidity does not drop below 60% during June and July. The plants develop a tree-like structure called an "ocak," formed by 5-6 branches each measuring 5-10 cm in diameter, with a moderately dense crown reaching heights of 2-3 meters.

Pollination: This is a monoecious species, meaning both male and female flowers appear on the same plant but in separate locations. The female flowers, known as "karanfil," start blooming in January, and are pollinated by male flowers called "püs," which release pollen during the same timeframe. Pollination concludes within 3-5 months. To ensure high fruit set, varieties such as palaz, mincane, foşa, and kalınkara should be planted in the orchard as primary pollinators, making up about 8-12% of the planting. Using a single pollinator variety is essential to consistently maintain fruit quality.
