When do osmanthus trees usually bloom?
Today, the editor will elaborate on when osmanthus trees usually bloom and introduce the green plant flowers related to the blooming time of osmanthus trees. Please see the detailed introduction below.
Before the scorching heat arrives, osmanthus trees are still in a vigorous growth stage. However, if the temperature remains above 32 degrees for a long time, the growth rate of osmanthus trees will slowly decrease, and they no longer grow as vigorously as in spring. When the growth rate of osmanthus trees slows down, do you think they are dormant? No, they will start a brand new growth mode. From mid-to-late June, osmanthus trees are secretly doing something related to blooming, and those who know about it have already changed their maintenance methods.
The new branches of osmanthus trees gradually stop growing
The vigorous growth period of osmanthus trees is from March to June (March to June in southern regions, and mid-to-late April to mid-to-late July in northern regions). During this period, they will rapidly grow new branches and leaves. Therefore, how much your osmanthus tree can grow in a year is basically determined from March to June. Because from mid-to-late June, as the temperature rises, the growth rate of osmanthus trees will decrease to varying degrees until it completely stops.
If your osmanthus tree is still rapidly growing new branches and leaves, strengthening sunlight and applying a balanced compound fertilizer with nitrogen, phosphorus, and potassium can still promote growth. If your osmanthus tree has already stopped growing, it means it has passed the peak growth season, and you should not force further growth. Forcing growth is useless and may even lead to unexpected problems.
Osmanthus trees enter the bud differentiation stage
From mid-to-late June, osmanthus trees successively enter the bud differentiation stage (the signal for entering bud differentiation is the cessation of growth in new branches). It takes about three months for osmanthus trees to go from bud differentiation to blooming. If your osmanthus tree blooms in September, it will undergo bud differentiation in June. If your osmanthus tree blooms in October, it will undergo bud differentiation in July.
When do osmanthus trees usually bloom?
Now that half of June is almost over, many osmanthus trees are secretly doing the bud differentiation process, which is closely related to the blooming in autumn. Those who know about it have already started changing their maintenance methods, while those who don't think that autumn blooming requires autumn maintenance. If you do not pay attention to the summer maintenance of osmanthus trees, no matter how much effort you put into autumn maintenance, you won't be able to get fragrant flowers.
Maintenance during the bud differentiation stage of osmanthus trees
Do not prune anymore
Osmanthus trees can bloom on both new and old branches, but actually, the flower yield of new branches is greater than that of old branches, with new branches being the main bloomers. The new branches of osmanthus trees that sprout in spring can differentiate into flower buds after maturing in summer and bloom normally in autumn. Now that it has entered summer, you should not prune osmanthus trees大幅ly. Otherwise, it may affect the blooming in autumn, resulting in fewer or no flowers to see.
Because if you prune osmanthus trees now, the new branches that grow will not mature in a short time and will not be able to differentiate into flower buds and bloom normally. The flower yield of old branches is limited, and it is inevitable that there will be few or no flowers in autumn. However, if your osmanthus tree has diseased branches or overly weak branches, you can still prune them moderately. Pruning diseased and weak branches saves nutrient consumption and increases the ventilation and light exposure of the plant, which is beneficial for bud formation.
