When is the best time to prune osmanthus trees?
Osmanthus trees can be pruned three times, mainly in March to April in spring, October to November in autumn, and January to February in winter. Before new buds sprout in early spring, mainly cut off the withered and weak branches, and then cut off the top 3-5 centimeters of the main branches along with the new buds. In winter, cut off the poorly growing and dense branches, which is good for its growth next year.
Osmanthus tree pruning time
Osmanthus trees can be pruned three times, mainly in March to April in spring, October to November in autumn, and January to February in winter.
Early spring pruning: Before new buds sprout in early spring, osmanthus trees can be pruned once, mainly cutting off the withered and weak branches, and then cutting off the top 3-5 centimeters of the main branches along with the new buds. This can promote more new branches to grow, making the tree more dense.
Winter pruning: In winter, osmanthus trees enter a dormant period with slow growth and are less likely to be damaged by pruning, so a heavy pruning can be performed. First, cut off the poorly growing branches, shorten the overly long branches, and thin out the dense branches, which is more beneficial for its growth next year.
Osmanthus tree pruning methods
When pruning young osmanthus trees, it is sufficient to keep a trunk of 50-60 centimeters and 3-5 lateral branches; the rest should be cut off. Pruning young trees not only ensures nutrition but also lays the foundation for the development of a beautiful shape of the osmanthus tree. Proper pruning can make the osmanthus tree bloom earlier and have a good ornamental effect in the initial stage.
The apical dominance of osmanthus trees is very obvious, with the main trunk growing faster than the lateral branches. Therefore, when pruning, the main trunk should be cut heavily, while the lateral branches should be cut lightly or not at all. In addition, the diseased, weak, dense, and inner branches should be cut off to make the osmanthus tree lush and beautiful. For mature osmanthus trees, no major pruning is necessary, only appropriate shaping pruning to maintain an elegant tree shape.
Osmanthus trees have a strong ability to sprout, and old stakes should also be pruned. The pruning method is similar to that of mature trees. Additionally, old stakes need to be pruned back every 2-3 years. The pruning back is usually done 10 days before the early spring sprouting. Before pruning, apply a mixture of 5% urea and potassium dihydrogen phosphate fertilizer. During pruning, cut off 2-3-year-old branches and dense branches, and make sure the cut surfaces are smooth.
Precautions for pruning osmanthus trees
After pruning osmanthus trees, they need to be provided with some water and nutrients because the trees need to grow new buds, which consume a lot of nutrients. If the nutrients are insufficient, the new buds will be weak and thin, and the leaves may become malformed. Choose multi-element fertilizers for fertilization.
