For osmanthus, the most suitable soil environment is slightly acidic, preferably between 5.5 and 6.5, and rich in humus. Generally, humus soil, garden soil and river sand are used in a ratio of 3:5:1. If there is no river sand, sand can be used instead.

PS: It is best to sterilize the culture soil before adding soil. You can use potassium permanganate solution or sun exposure.

According to the growth needs of osmanthus, the principle of choosing a flower pot is good drainage and ventilation performance, and a clay pot will do.

3. Do I need to change the pot? How often should it be changed?

Osmanthus potted plants need to be repotted because the nutrients in the culture soil in the pot are limited. If the pot and soil are not changed for a long time, the growth of osmanthus will be restricted. Generally, the pot needs to be repotted once every one or two years, preferably in early spring.

4. How to water osmanthus?

Remember three specific time periods and you won’t have to worry about watering. Water the osmanthus less when it is just sprouting, water it less in the rainy season, and water it more in summer and autumn. After watering in the morning in summer, check in the evening. If you find that the soil in the pot is dry, water it again, but be careful not to accumulate water. Normally, water it once every three to five days.

5. How to fertilize osmanthus?

Start fertilizing after the osmanthus flowers sprout in spring, and apply a thin layer of cake fertilizer water to the flowers once every ten days. In summer, change to compound organic fertilizer in July and August, and then change to phosphorus fertilizer in September, which will help promote the blooming of osmanthus.

6. Should osmanthus be pruned? How to trim?

Potted osmanthus should be shorter and stronger so that it looks better when it blooms, so it needs to be pruned.

Before pruning:

After pruning:

Pruning can be done twice a year. The first time is in autumn, after flowering, when the overgrown branches of the plant can be shortened, and branches that are too dense and too long can be cut off according to their growth. The second time is in early spring, when the dead branches and weak twigs on the plant are cut off before the osmanthus flowers sprout.

What to do if the leaves of osmanthus turn yellow

One look at watering.

Osmanthus is a flower that is afraid of waterlogging. Once water accumulates, its leaves will turn yellow or even fall off. Therefore, you must be careful when watering osmanthus. Do not water unless the soil is dry. If you need to water, water it thoroughly.

Second, look at fertilization.

If osmanthus is not fertilized for a long time, it is very likely that the leaves will turn yellow due to insufficient fertilizer. Therefore, during the growing period of osmanthus, some nitrogen fertilizer should be applied to it regularly to promote the growth of branches and leaves.

Third, check the ventilation.

When the environmental ventilation conditions are poor, the plants are prone to being infected by diseases. The most common manifestation is that the leaves of osmanthus turn yellow and black, so pay attention to maintaining good ventilation.

What to do if the osmanthus flower tips are dry

A look at the light.

Compared with other flowers, osmanthus prefers sunlight. Long-term lack of light will cause the leaves of osmanthus to turn yellow and dry, so it is best to grow osmanthus in a place with good light.

Second, look at the humidity.

If the humidity in the environment where the flower lover lives is relatively low, it will also cause the tips of the osmanthus leaves to dry out. At this time, you should pay attention to shade and spray water on the plant to keep it moist.

Third, look at the temperature.

The suitable growth temperature for osmanthus is around 20 degrees. If the temperature is lower than 10 degrees or as high as 30 degrees, the leaves of osmanthus will turn yellow. Therefore, pay attention to moisturizing and cooling in summer, and do a good job of cold prevention in winter.
