Why Don't Osmanthus Trees Bloom
Today's experience sharing: The content about why osmanthus trees don't bloom in green plant and flower planting will definitely help you. Let's learn about it together!
Why Don't Osmanthus Trees Bloom
Osmanthus trees may not bloom if the soil is too alkaline or compacted, which can limit their growth and result in no flowers for 3-5 years. If there is insufficient sunlight for an extended period, the flower buds cannot form. Improper watering, whether too much or too little, can also cause this issue. Excessive application of nitrogen fertilizer and unbalanced fertilizer ratios are also reasons.
Osmanthus Tree Blooming Time
In the solar calendar, the blooming period of osmanthus flowers is from September to October, which is autumn. The osmanthus trees that bloom during this period are the classic Dan Gui, Yin Gui, and Jin Gui, collectively known as August Osmanthus.
Besides, there are everblooming osmanthus trees, such as the four-season osmanthus, which blooms every 2 to 3 months. The blooming period of most varieties is short, only 20-30 days, but the fragrance is strong.

Yellowing Leaves on Osmanthus Trees That Don't Bloom
Excessive Watering: If the leaves of the osmanthus tree turn yellow due to too much water, control the amount of water, and only water when the soil is not dry.
Insufficient Light: If it is due to insufficient light, provide 6 to 8 hours of light every day.
Improper Temperature: Adjust the temperature to 14-28℃, if it is too humid, place it in a well-ventilated area, and if it lacks nutrients, supplement fertilizer promptly.
Osmanthus Tree Planting and Blooming Methods
1. Soil: Osmanthus trees prefer loose, fertile, and acidic soil. When preparing the soil for osmanthus, you can use garden soil, peat soil, and sandy soil. You can also add some decomposed chicken manure as a base fertilizer at the bottom of the pot.
2. Light: When planting indoors, ensure that it receives 8 hours of light a day. If there is insufficient light, the leaves of the osmanthus tree may wither, and during winter, insufficient light can cause the tree to shed leaves.
3. Temperature: 15-28℃ is the optimal temperature for the growth of osmanthus trees, so in summer, provide shade and coolness, and in winter, move the tree to a warm place indoors.
4. Watering: Osmanthus requires moderate watering. In spring and autumn, water every 2 to 3 days. In summer, increase the frequency due to evaporation, possibly watering twice a day. In winter, when the plant enters dormancy, reduce the watering frequency.
5. Fertilizing: During the growing season, fertilize with diluted decomposed cake fertilizer every week. Before the blooming period in autumn, applying some phosphorus fertilizer can help it grow and bloom.
