 ✤ Cultivation methods for four-season osmanthus andprecautions
  1. Water conditions. Watering four-season osmanthus needs to be moderate, and the principle of two less and one more should be mastered. Plants that are repotted before new shoots appear need less watering, and less watering is also needed during rainy weather, while in dry weather such as summer and autumn, more watering should be given. After repotting and watering thoroughly, it is also necessary to regularly maintain a water content of about 50%. After entering the dog days from July to September, the soil water content should be about 60%. Generally, if the potting soil can be pinched into a ball by hand and then crumbles when released, that is enough moisture. At the same time, attention should be paid to drainage on rainy days to prevent root rot and drowning caused by water accumulation.
  2. Soil conditions. Four-season osmanthus likes to grow in slightly acidic, well-drained, and fertile sandy loam. On the contrary, four-season osmanthus grows relatively slowly in strongly acidic soil, with yellowing and withered leaves and few branches, showing a phenomenon of malnutrition. Generally, for two-year-old seedlings grafted in soil with a pH value of 3~4, the branches in that year are generally 2~3, with branch length of about 6 cm, which is 2 times fewer branches compared with soil with a pH value of 6. In alkaline soil, four-season osmanthus shows leaf withering within two or three months and gradually dies.

  3. Fertilization conditions. People all say that vigorous flowering depends on fertilizer. Four-season osmanthus relatively likes and is suitable for pig manure as fertilizer. We can mix it into the potting soil or place it at the bottom of the pot after decomposing and drying in the sun. The fertilization amount is generally based on 1/4 of the pot height, and a layer of soil about 1~2 cun thick needs to be covered over the fertilizer, then four-season osmanthus is planted, and no further fertilization is needed within one year. If grown in urban areas, water soaked from the hooves of donkeys, horses, or mules can be used, applied once when buds sprout in spring, and then once every 7 days~10 days before August.
  4. Shaping conditions. Four-season osmanthus is a plant with strong ornamental value, mainly for foliage, form, and flowers. Although this osmanthus has small flowers, it is relatively fragrant, and its leaves and form are very beautiful. Therefore, when shaping osmanthus, we need to express an air of prosperity and wealth, solemnity, and elegant purity. To achieve beauty, we can use privet as rootstock, and first move large-leaf privet into a flower pot. From the summer solstice to the autumn equinox, the approach grafting method can be used throughout this period. After survival, cut the osmanthus from the mother plant to form a new osmanthus plant, and it can generally survive.

Conclusion:Four-season osmanthus is a precious flower in our country. It not only has a very wide range of admirers but also has high economic value, and is deeply loved by people. Its flowers are beautiful and its fragrance is pleasant. It is often planted as a landscape tree and has high ornamental value.

1. Cultivation methods for four-season osmanthus——planting

Four-season osmanthus is suitable for cultivation in August and September. Before planting, make sure to loosen the soil. Soft soil can help improve fertility and has better air permeability, which is more favorable for the later cultivation of four-season osmanthus. Better soil air permeability can also be more conducive to the absorption of nutrients and nourishment.

2. Cultivation methods for four-season osmanthus——fertilization

What four-season osmanthus needs is organic fertilizer, and using some calcium phosphate as fertilizer is more suitable. For annual cultivation of four-season osmanthus, the fertilizer amount per mu can be reduced to 10 kg. When fertilizing, it should be even so that the soil can absorb nutrients evenly. Keep the bottom of the water ditch per mu smooth so that water can flow smoothly.

3. Cultivation methods for four-season osmanthus——irrigation

Four-season osmanthus needs to maintain a constant flow of water in the ditch. The size of the water flow should be related to the growth stage and season. Northern regions need more water, while southwestern regions need less. In cold weather, the amount of water can be increased, and in warm weather, the amount of water should be reduced. The amount of water should be changed on rainy or clear days.

4. Cultivation methods for four-season osmanthus——topdressing

Cultivation methods and precautions for four-season osmanthus

Four-season osmanthus is a very excellent variety among osmanthus. From its name, we know that it blooms in all four seasons, and its fragrance is very drifting. In summer and autumn when the flowers bloom, the fragrance of the flowers is even richer. In winter and spring, the floral fragrance is not so rich. It is often planted in gardens, generally appearing on both sides of roads, in courtyards, on lawns, and other places, while in the military, government organs, enterprises and institutions, schools, streets, home greening, and so on, it is a very excellent tree species. Below let us take a look at the cultivation methods and precautions for four-season osmanthus.

[Introduction to four-season osmanthus]

Four-season osmanthus is an evergreen arbor plant. Its root system is very developed, and its leaves are opposite. Its plant height is about 15 m, and its crown can cover 400 sq m. The seedling of osmanthus has a very obvious taproot. Its young roots are light yellowish brown, while old roots are yellowish brown. Its leaves are very smooth and leathery. The adaxial surface is dark bright green, while the abaxial surface is relatively lighter in color, with two or three pairs along the leaf. Four-season osmanthus grows more abundantly in areas south of the Yangtze River basin, and in northern regions it is generally grown as a potted plant. In the northern subtropical zone it is a deciduous plant, and evergreen broad-leaved trees are mixed in forest areas. In the central subtropical zone it is an evergreen plant in deciduous broad-leaved forest areas, and it has very good garden ornamental value.

[Growth habits of four-season osmanthus]

Four-season osmanthus is a plant of strong and weak adaptability. It likes to grow in warm and humid environments and has a certain cold resistance, but it is not particularly tolerant of severe cold. It also likes to grow in environments with relatively sufficient light and has a certain shade tolerance. During the seedling stage, certain shading treatment is needed. Its requirements for soil are not particularly strict. It likes to grow in slightly acidic soil with relatively high terrain, dryness, and rich humus. It needs to grow in a fertile and humid environment, and growing in sandy soil with relatively deep soil layers and good drainage is most suitable.

[Propagation methods for four-season osmanthus]

The propagation methods of four-season osmanthus include seed propagation, layering propagation, and cutting propagation. If used for flower beds and garden arrangement, the plant height needs to be 2-3 m. If it is a household potted plant, it needs to be dwarfed to below 1 m. Its trunk has relatively many branches, and its leaves are also relatively fine. Its seedlings can bloom and fade after one year of growth, and when grown for more than three years, the flowers will be even larger and have very good value. During planting, plant ash and bone meal need to be applied as phosphorus and potassium fertilizer, which makes the flowers bloom more luxuriantly and the fragrance of the flowers even richer. It is necessary to effectively prevent anthracnose, leaf spot disease, flat thorn moth, wax scale insect, and so on, and ensure that the plant can grow and develop normally, so that flowering will be more luxuriant.

[Cultivation methods and precautions for four-season osmanthus]

1. Soil: Four-season osmanthus likes to grow in slightly acidic sandy soil with sufficient light, warmth, depth, good drainage, fertility, and rich humus. It is not tolerant of barrenness or drought. In shallow and compacted soil, its growth speed is very slow, and the leaves it grows are very few, the leaves are also relatively small, the leaf color turns yellow, flowering will be very sparse, and in severe cases it can cause withering, thus failing to bloom.
2. Light: Four-season osmanthus is a plant that likes light. It has a certain ability to tolerate shade. During the seedling stage, it needs to be placed in a shaded place for cultivation, while under sufficient growth conditions, give sufficient light to ensure the normal growth of four-season osmanthus. The osmanthus tree also needs to be placed in a light-transmitting and ventilated place to grow, and it likes to grow in a clean environment. It is not tolerant of smoke and dust. If harmed, it will cause the plant not to bloom.

3. Water: When it encounters water accumulation, its roots will turn black and rot, and the leaf tips will be scorched and withered, after which the entire leaves will turn yellow and fall off, thus causing the death of the plant. Its cold tolerance is also not particularly strong, so attention should be paid during cultivation.
4. Prevention and control of diseases and insect pests: The disease commonly encountered by four-season osmanthus is blight spot disease. It usually starts from the leaf margin and leaf tip. At the beginning of the disease, light brown spots will appear on the leaves, and they will slowly expand into round and irregular lesions, gradually forming large grayish brown spots with dark brown edges. The onset time is generally from July to November, and timely prevention and control are needed.
