When is the best time to repot osmanthus trees that bloom all year round
Today, we will introduce a small experience about the best time to repot osmanthus trees that bloom all year round. Let's learn about it together.
When is the best time to repot osmanthus trees that bloom all year round
Repotting and changing the soil for osmanthus trees that bloom all year round should be done in late winter and early spring, specifically in February or March. For potted osmanthus trees, special attention should be paid to the care and management of soil, water, fertilizer, temperature, and light, these five major aspects. Additionally, it is important to control the humidity and the day-night temperature difference in the local environment. The general temperature difference should be around 10°, with air humidity maintained at about 65% to 70%.
When is the best month to repot osmanthus trees that bloom all year round
Repotting and changing the soil for osmanthus trees that bloom all year round should be done in late winter and early spring, specifically in February or March. This is because, at this time, the osmanthus trees have not yet started to sprout, and repotting with new soil will not interfere with their sprouting growth, making it more conducive to their root establishment and growth.
Osmanthus trees, as a precious ornamental tree species, are more suitable for large-scale cultivation and should be planted shallowly, not deeply. So, what issues should be considered when repotting osmanthus trees that bloom all year round?
How to care for osmanthus trees after repotting
1) Cultivation soil should be fertileWhen potting osmanthus trees that bloom all year round, to ensure better growth, flowering, and fragrance, the potting soil should be loose, breathable, fertile, and have good water drainage and nutrient retention properties, preferably sandy loam.
It is generally best to use peat soil rich in organic matter, mixed with some decomposed leaf soil, in a ratio of 2:2:1 to create a growing medium. Then, plant the osmanthus trees in a pot with a diameter about 5 inches larger than the canopy.
2) Sufficient light is necessary for vigorous growthOsmanthus trees enjoy sunlight and are long-day plants. Therefore, potted osmanthus trees should be placed in a location with ample sunlight and good ventilation for care and management. This ensures that their branches and leaves grow vigorously, and the flowers have a strong fragrance when blooming.
The duration of daily sunlight should be maintained at 8 to 10 hours or more. Insufficient sunlight or a阴暗 environment can lead to sparse foliage and affect flowering.
3) Temperature control needs to be appropriate
Osmanthus trees require a period of low-temperature dormancy in winter for bud differentiation, with the care environment temperature controlled at around 3 to 5°C.
If the temperature is too high, above 10°C, and the physiological need for low-temperature dormancy is not met, it will affect the following year's flowering. Even if flowering occurs, the fragrance will be faint.
4) Water management should be properBefore new shoots appear, osmanthus trees should be watered sparingly, just enough to keep the soil slightly moist and not dry.
During the plum rain season, watering should be reduced; in hot summer, watering should be increased appropriately, and water should be sprayed on the leaves and the surrounding ground twice a day, in the morning and evening, to lower the temperature and increase humidity.
However, avoid waterlogging in the pot, as it can easily lead to root rot. In early September, when the flower buds start to sprout, maintain the soil moisture and add water appropriately to facilitate normal flowering.
5) Fertilizer supply should be appropriateOsmanthus trees have a strong branching ability and can easily develop a spherical canopy. Therefore, except for severe cold and heat, osmanthus trees can bloom multiple times a year.
Especially in autumn, they bloom the most. Therefore, osmanthus trees consume a large amount of nutrients and should be fertilized with a base fertilizer every November to December, allowing the potted osmanthus trees to produce more lush branches and leaves the following spring, which is conducive to bud differentiation.
Before new branches sprout again, apply a top dressing to promote new growth and ensure that the autumn flowers are large and dense.
