Methods for Fertilizing Osmanthus
The editor is here to answer questions about the methods for fertilizing Osmanthus, providing knowledge on the topic of flowers and plants. Let's delve into the details together.
How should Osmanthus be fertilized? This is a question many flower enthusiasts want to ask, especially for potted Osmanthus. Incorrect fertilization can easily cause fertilizer damage, but without fertilization for a long time, Osmanthus may grow weakly due to insufficient nutrients and fail to bloom. Today, I'll briefly introduce the fertilization methods and timing for Osmanthus.
Osmanthus Introduction
Osmanthus is a common name for many trees in the Osmanthus genus in China, which are evergreen shrubs or small trees. Among horticultural varieties, Jin Gui (Golden Osmanthus), Yin Gui (Silver Osmanthus), Dan Gui (Red Osmanthus), and Yue Gui (Moon Osmanthus) are quite representative. Osmanthus is one of the top ten famous traditional flowers in China and is widely used in landscaping in many places.
Among the four representative varieties of Osmanthus, Yue Yue Gui (also known as Four-Season Osmanthus) blooms in multiple seasons throughout the year but has a relatively light fragrance, or is even odorless. So for those who enjoy the fragrance of Osmanthus, it is recommended not to choose Yue Yue Gui, as it is somewhat impractical.
The varieties with a stronger fragrance are Jin Gui and Yin Gui, with Jin Gui having golden flowers and Yin Gui having white flowers. Both Jin Gui and Yin Gui bloom in autumn. Dan Gui has a particularly nice flower color, with a red hue, making it relatively more attractive. However, its fragrance is slightly less intense than that of Jin Gui and Yin Gui, though it is still fragrant.

The fertilization method and frequency for Osmanthus are related to the cultivation environment and also to the variety.
If it's an autumn-blooming Osmanthus variety planted in the ground, usually 2-3 applications of fertilizer per year are enough. For potted autumn-blooming Osmanthus varieties, 3-4 key applications of organic fertilizer per year are recommended, along with a monthly application of organic liquid fertilizer.
Ground-Planted Osmanthus Fertilization Method and Timing
For ground-planted Osmanthus, a solid-fermented organic fertilizer is usually applied once when the branches sprout in March of the spring. This can include fermented sheep manure, chicken manure, etc. Then another application of fermented chicken manure and bone meal is made in May-June.
Fertilization should be done using the shallow trench method. A shallow trench is dug around the roots of the Osmanthus tree, the fermented organic fertilizer is placed in the trench, and then the soil is covered back.
In winter, in areas with lower temperatures, a layer of fermented organic fertilizer or compost can be covered around the soil surface of the Osmanthus roots. This can help retain heat and also provide the necessary nutrients for the plant in the spring.
