You may not be aware of the experience in plant maintenance regarding whether a newly transplanted osmanthus tree can be pruned. Let's find out together.
Can a newly transplanted osmanthus tree be pruned?
After repotting a potted osmanthus tree with new soil, when it starts growing and becomes accustomed to the pot, we can promote the tree to sprout more new branches by methods such as breaking branches to force buds and adjusting the angle of branches. This creates more space for new branches to grow, further enhancing the plant's photosynthesis and ensuring sufficient nutritional accumulation, which is concentratedly supplied to the growth and development of new shoots. This can promote a full and round crown for the osmanthus tree, resulting in more flowers.
In fact, the purpose of pruning a potted osmanthus tree is to promote the sprouting of terminal buds, making the tree's crown more full and round.
After repotting a potted osmanthus tree with new soil, once it has become accustomed to the pot and starts growing, we should prune it according to the condition of its shape.
We know that the germination rate of osmanthus branches is relatively low, usually only one terminal bud sprouts on one branch, and it is rare for more than two branches to sprout. Many lateral buds around it remain dormant, presenting a state of single shoot extension growth.
So, how should we prune to promote a fuller crown for the potted osmanthus tree? What kind of pruning should be done? What aspects should be considered?
1) Breaking branches to force buds for a full crownWhen most of the new shoots that sprout in spring stop growing and form a tip, break off all new branches from the base to force the branches to sprout terminal buds.
If it's a tree seedling that has been cultivated for more than three years, sometimes in order to maintain balanced growth of the crown, 1~2 new shoots can be retained in areas where branches are lacking, but do not keep too many, as it will affect the bud-forcing effect.
As the top growth advantage of the osmanthus branches is disrupted, it forces the nutritional growth points to be reallocated.
At the same time when new branches sprout in early spring, it is also a stage when the roots grow vigorously, but suddenly all new shoots are broken off, breaking the balance between roots and branches and prompting the lateral buds around the branches to sprout rapidly.
Usually, after about 10 days, they all sprout together, which is 3~5 times more than the original fallen new branches, or even more.
Because the new branches that are forced out multiply, the nutrients are more scattered. Therefore, the new branches grow short and compact, which is beneficial for the early formation of the crown and for the osmanthus tree to enter the flowering stage.
This is the good effect shown by breaking branches to force buds and is an effective method to promote a full crown for the potted osmanthus tree.
2) Adjusting the angle of branchesIn conjunction with the above measures, when breaking branches to promote buds in the osmanthus tree, the angle of the branches should be adjusted to make the crown spread out and grow, reducing the top growth advantage, thus promoting more bud sprouts.
This allows more space for new branches to emerge, enhancing the crown's photosynthesis, and ensuring more comprehensive accumulation of nutrients, which is beneficial for the expansion and growth of the osmanthus tree crown.
The above is an introduction to the methods of pruning a newly transplanted osmanthus tree, which can be used as a reference suggestion for everyone.
