Pruning Methods and Key Technical Points for Jasmine
In southern China, jasmine grown under normal cultivation conditions sprouts 6-8 batches of new branches each year. As the branches grow older, they continuously increase in number, grow taller, and gradually age. Branches that are too old and too long hinder the transport of water and nutrients, and plants that are too tall also affect field work such as flower picking. Pruning is an important production technique for rationally adjusting the layout of branches and leaves and promoting robust plant growth.
The most important pruning task of the year is spring pruning. In Hengxian, Guangxi, jasmine branches generally begin to sprout in early to mid-February and sprout abundantly in early to mid-March. Before reaching the optimum temperature for bud formation (25°C), jasmine only undergoes vegetative growth; after reaching the bud formation temperature, new shoot growth and flower bud differentiation proceed almost simultaneously.
