When does osmanthus bloom and how long is its flowering period?

1. What season does it bloom?

There are many varieties of it, and different varieties naturally have different flowering times. However, from a seasonal perspective, it is mostly concentrated in autumn, specifically between September and early October. Among them, the common varieties are golden osmanthus, silver osmanthus and red osmanthus. There is another variety called Osmanthus fragrans, which, as its name suggests, can bloom in all seasons. However, compared with other varieties, it has fewer flowers and a lighter fragrance.

2. How long is the flowering period?

Its overall flowering period is not long, usually lasting more than 20 days. However, if the flowering period is managed properly, the time can be extended, and the longest will not exceed 2 months. Although the flowers are small when they bloom, they have a strong fragrance that spreads from far away, so they are also very popular. Of course, the flowering period of Osmanthus fragrans lasts longer, about half a year in total, and it blooms every two or three months.

3. How to manage the flowering period

If you want it to bloom longer, you must pay attention to the management of the flowering period. Expose it to more sunlight and fertilize it frequently before flowering. Usually place it in the light, and just block it when there is strong light. When applying fertilizer, you should choose fertilizer types scientifically and apply more phosphorus and potassium fertilizers before flowering to promote the differentiation of flower buds. However, after flowering, you should reduce light and stop fertilizing, otherwise it will cause the branches and leaves to grow vigorously, and the flowering period will end prematurely. Also, reduce the amount of watering.
