How many times does Osmanthus fragrans bloom in a year?
Summary: This article introduces the blooming frequency of Osmanthus fragrans and how to care for it to ensure flowering, as well as the management after the flowers fade. Let's take a look!
The blooming frequency of Osmanthus fragrans in a year
Osmanthus fragrans has two varieties, one that blooms in autumn, flowering only once a year, and the other that blooms throughout the year, known as "monthly osmanthus." Osmanthus fragrans belongs to the dicotyledonous plant class, the twisted flower order, the Oleaceae family, and the Osmanthus genus, which is an evergreen ornamental plant. Osmanthus fragrans is also known as cassia.
Flowering period: Osmanthus fragrans usually blooms in autumn, specifically from the late September to the early October, with a short flowering period of about 20-30 days.
How to care for Osmanthus fragrans to make it bloom
Placement: Osmanthus fragrans is a long-day plant that prefers a sunny environment and can tolerate strong light. Therefore, it can be maintained in the sun. If the lighting environment is poor, it will cause the plant to grow excessively, resulting in fewer or no flowers.
Adequate nutrients: Osmanthus fragrans is suitable for planting in fertile, loose, well-drained slightly acidic soil. You can also mix it with mountain soil or decomposed leaf soil, garden soil, and river sand. During the growing period, nitrogen fertilizer can be applied, but it should be reduced before the flowering period, with an increase in phosphorus and potassium fertilizers.
Proper watering: Osmanthus fragrans requires more water but is afraid of waterlogging. Keep the soil moist but avoid waterlogging to prevent root rot.
Avoid smoke and dust: Osmanthus fragrans is sensitive to environmental conditions, especially to coal smoke and kitchen oil fumes. The air quality of the care environment must be good.
Pruning: Osmanthus fragrans has a vigorous growth, so you can prune the overly long, old, diseased, and overlapping branches to reduce nutrient consumption, promote the growth of lateral branches, and focus nutrients on the flowering branches to encourage blooming.
How to manage Osmanthus fragrans after flowering
After the Osmanthus fragrans flowers fade, it is necessary to prune the残花 (residual flowers) and flower stems promptly, as well as to remove the old, weak, and diseased branches to reduce nutrient consumption and also benefit the flowering in the following year.
