this recent message from El Injerto was very helpful in understanding this topic:
There are three different ways Coffee Arabica can pollinate:
-- Self-pollination: 91 to 93 percent of this specie pollinates naturally.
-- Cross-pollination: 7 to 9 percent pollinates naturally, with the help of bees. New varieties are created.
-- Artificial-pollination: with the help of men resulting in new varieties.
The main factors that contribute to an effective pollination are:
1. The species and the variety cultivated: particularly the age of the eggs of the plant.
3. Rain. It could wash the eggs remaining in the stigmas.
4. Capacity of stigmas to capture pollen.
5. Nutritional status of the plant.
6. Growing regulators.
If you visit El Injerto at the end of the dry season, you will notice all coffee plants are covered with beautiful white flowers with five or six petals, very similar to jasmine. After pollination is over, flowers become fruits within two or three months. After six or eight months, cherries will be ready to harvest.
As you can see, nature is in charge of pretty much everything. The three basic ingredients for you to enjoy a great cup of coffee are:
1. The physical environment: the micro climate, type of soil, altitude… The “ideal conditions” for growing coffee.
2. The plant and its natural input: we can´t create plants, but we can select the specie and the proper varieties for the physical environment we plant in.
3. Our knowledge and experience in managing the plant in the field, the wet and dry process.
El Injerto's commitment is to maximize these three ingredients and our experience to produce the best quality coffee. El Injerto's quality approach is to delight you with a unique sensorial experience.
