The growth of coffee trees

The growth and fruit of coffee trees varies with different varieties / environmental conditions. In the high altitude area of Yunnan, the small seed coffee cultivated has the advantages of cold climate, large cloud cover, short light and slow plant growth, but the branches develop into sturdy backbone branches after the first branch bears fruit, and the second / third branch has strong ability to produce. The growth is exuberant and the fruit is dense, which is the main fruiting branch, so it is suitable to adopt single trunk shaping. Two / three branches bear fruit and die after 2 or 3 years, and then sprout two / three branches from the backbone branches.

The flowering and fruiting habits of a branch produced in different months of the year are different.

The growth and fruiting habits of the first / second branch of coffee vary with different types and stages: the first branch can be divided into three types:

The first type: the first branch from February to May each year, mainly vegetative growth, the largest growth in the current year, most of the two branches in the next spring, the robust branches in the same year (July to September), individual branches can blossom and bear fruit in the following year. In single-stem plastic surgery, a branch of this type is selected to cultivate backbone branches.

The second type: a branch from June to September every year, after which the reproductive growth and vegetative growth are carried out at the same time. Therefore, every branch can blossom and bear fruit in the next year, and rarely produce two branches. The part of a branch that continues to grow will blossom and bear fruit in the third year, which is the main fruiting branch in the third year.

The third type is a branch which is produced after September, because it enters a period of low temperature and drought shortly after harvest, grows slowly, grows slowly in that year, only 1-6 nodes, blossoms and bears fruit in the next year, continues to grow in the next year, and can produce two branches. The growth and fruiting habit of the second / third branch of the small seed species is different from that of the first branch. The climate is suitable and the management is normal. 2-3 times per year (February-March / May-June / August-September). The branches extracted at the beginning of the year have a large growth in that year and bear more fruit in the next year, while those in autumn have less growth in the same year and less fruit in the next year. But the next year continued a large amount of growth, the third year a large number of results.
