Why don t osmanthus flowers bloom in September Why don t osmanthus flowers bloom in August?

Osmanthus flowering period 9 October, the soil requirements are not too strict, except for alkaline soil and low-lying land or too clayey, poorly drained soil, can generally grow, but the soil layer is deep, loose and fertile, well-drained slightly acidic sandy loam is the most suitable.

Sex likes warm, moist. The average temperature in the planting area is 14 28, the average temperature in July is 24 28, the average temperature in January is above 0, the minimum temperature can be tolerated -13, and the most suitable growth temperature is 15 28. Humidity is extremely important for the growth and development of osmanthus, requiring an average annual temperature of 75 85, annual precipitation of about 1000 mm, especially when young and adult trees need more water when flowering, if drought will affect flowering, strong sunlight and shade are not conducive to its growth, generally require 6 8 hours of light a day.

Osmanthus prefers a warm environment and should grow in a deep, well-drained, fertile, humus-rich acidic sandy loam soil. Not tolerant to drought and barrenness, on the shallow and barren soil, the growth is particularly slow, the branches and leaves are scarce, the leaves are thin, the leaf color is yellow, there is no flowering or very little flowering, and even there is a periodic withering phenomenon, and the whole osmanthus plant dies when it is serious; It loves sunlight but has a certain ability to tolerate shade. Young trees need to have a certain shade, and they need to have relatively sufficient light when they become adults to ensure the normal growth of osmanthus.

It is observed that when one side of the crown of a single osmanthus tree is close to the wall, or when the canopy of two osmanthus trees overlaps each other, the side close to the wall or the part of the crown that overlaps staggered and overlapped will soon become sparse, affecting the shape and beauty of the entire canopy. It can be seen that osmanthus is suitable for planting in a ventilated and light-transmitting place; Osmanthus likes a clean and ventilated environment, is not resistant to smoke and dust hazards, and often cannot bloom after being damaged; Afraid of waterlogging and waterlogging, if it is harmed by waterlogging, the root system will be black and rotten, the leaf tip will be scorched and withered, and then the whole leaf will wither and fall off, which will lead to the death of the whole plant; It is not very cold-tolerant, but it is still a relatively cold-tolerant tree species compared to other evergreen broad-leaved tree species, which provides the possibility for potted osmanthus in the north.

の is the season that has not yet opened. Understand?

If it's opened. The osmanthus tree of the Goose Gate School is super fragrant

Some people manage osmanthus flowers that grow well, but they don't bloom for several years. There are two main reasons why osmanthus does not bloom:

First, the flowering age is late.

Osmanthus has a long lifespan, so it blooms late, the seedlings take about 10 years to bloom, and the cuttings take 4 years, and they will not bloom if they do not reach the flowering age.

2. Improper maintenance and management.

1 soil discomfort osmanthus is suitable for slightly acidic, fertile, well-drained culture soil, can be prepared with humus and sandy loam soil half, avoid saline, avoid waterlogging. If the soil is too acidic, it will grow slowly, and even the leaves will turn yellow. If alkaline soil or calcareous soil is used, the branches and leaves will wilt and even the whole plant will die in about two or three months.

2 Insufficient light Osmanthus likes light and needs more than 10 hours of light, otherwise the branches and leaves will not grow luxuriantly, affecting the pregnant buds and flowering, therefore, attention should be paid to giving sufficient sunlight.

3 soil moisture content is not suitable osmanthus avoid drought, often maintain the humidity of potting soil 50 to 60, 60 to 70 degrees in hot days, too much water is easy to rot roots, fallen leaves, and even cause physiological diseases. On rainy days, it is necessary to drain the water in time to prevent root rot.

4 improper fertilization should be based on phosphorus and potassium fertilizer, with more phosphorus and potassium fertilizer, thin Bika water-soluble fertilizer, April to May every half a month, June to July every 10 days to apply, in early August again after the fertilizer, before the winter again to apply basal fertilizer again, to ensure the differentiation of osmanthus flower buds. Excessive fertilization or nitrogen fertilization will cause branches and leaves to grow and affect flowering.

5 Do not prune Osmanthus germinates strongly, and generally pulls the shoots twice a year. The long branches and diseased branches should be pruned in time, and the plant shape should be appropriately shortened to concentrate nutrients.

6 Smoke and oil scale stain leaves If the leaves are polluted by smoke and oil scale for a long time, they will grow poorly and even fall off, affecting flowering. It is even more effective if the leaves can be cleaned at the same time as the root topdressing.

7 High overwintering temperature In winter, if it is placed in more than 10 places, it will make osmanthus bud and spread its leaves prematurely, consume a lot of nutrients, coupled with insufficient light, smoke pollution, and weak plants. In spring, when the wind and sun go out of the house, the leaf tips are dry, and even if new shoots sprout again, it is not easy to bloom. Therefore, it is not necessary to enter the room when the temperature is above 3, and the overwintering temperature is between 3 and 5.

Overwinter in a cold room from 0 to 5 to promote dormancy.

(1) Improper maintenance in winter. After entering the room in winter, it should be placed in a low temperature place to make it fully dormant, and the next year it will grow robustly and the flowers will flourish. If the room temperature exceeds 10 in winter, the plant does not go through the low-temperature dormancy stage, and the delicate branches are extracted in advance, which consumes a lot of nutrients, which will affect the flowering of the next year.

If you water too much in winter, it is easy to cause rotten roots and leaves, and the growth of plants in spring is weak, and the branches that sprout are also very weak, thus affecting flowering. (2) Improper placement. Osmanthus is a long-day plant, with lush branches and leaves under full sunshine conditions, dark green in color, many flowers, and strong fragrance.

If it is cultivated in a shaded place for a long time, the plant will not get enough light, which will cause the branches to grow, which will affect the differentiation of flower buds, and will cause osmanthus to not bloom or bloom less. (3) Poor cultivation management. If osmanthus is planted in alkaline soil or calcareous soil, the root absorption function is hindered, and the plant growth is poor, thus affecting flowering; Potted osmanthus has not been repotted and changed for a long time, so that the nutrients are insufficient, and the root system can not be stretched, which will also affect flowering; Excessive application of nitrogen fertilizer and excessive vegetative growth will make the flowers less and lack fragrance, or even no flowering; If the soil is too wet and the roots rot or the high temperature and dryness for a long time will affect the differentiation of flower buds, resulting in little or no flowering.

The optimal air humidity of osmanthus is 70% 80%, if the air is too dry, there will be yellow leaves, dry tips, dry edges, and even no flowers or poor flowering.

Because of the different varieties of osmanthus, the flowering time is also different, the golden osmanthus, silver osmanthus and osmanthus bloom from September to October, and the four seasons of osmanthus bloom every month. The climate in the south is good, and the growth of osmanthus is large, so the flowering period will be a few days later than that of osmanthus in the north. In addition, the climate will vary from year to year, and the flowering period of osmanthus will also be different.

Why don't laurels bloom? There is a song that in August osmanthus flowers bloom everywhere, but I don't know why they don't bloom.

Osmanthus generally blooms in September and October every year, but the specific flowering time varies depending on the variety. Osmanthus planting method: It is recommended to use humus soil, pastoral soil, and river sand soil in accordance with 5:

4:3 ratio mixed preparation planting; It is suitable for growing in a sunny environment, the more light there is, the more flowers will be; Water once every 2 or 3 days during the growing season, once in the morning and once in the evening in summer, and once every 10 days or so in winter.

Osmanthus flowers generally bloom in September and October every year, but the specific flowering time varies depending on the variety. For example, the Four Seasons Osmanthus Flower, as the name suggests, is an osmanthus that blooms all year round, starting from September to March of the following year, and will bloom in batches, with a strong floral fragrance and high ornamental value.

1. Slightly acidic soil

Osmanthus likes to grow in the slightly acidic soil with soft soil and good drainage and air permeability, and the pH value is the best between, and it is not suitable to use alkaline soil for planting, which is easy to cause branches and leaves to dry up and wither. It is recommended to use humus soil, pastoral soil, and river sand soil according to Kaiqiao Rolling 5:4:

The ratio of 3 is mixed and planted, and the high soil porosity is conducive to the growth of osmanthus trees.

2. Sufficient light

Osmanthus is suitable for growing in a sunny environment, the more light there is, the more flowers will bloom, and the stronger the fragrance. At the seedling stage of osmanthus flowers, it is recommended to maintain them in a place of astigmatism to avoid burns on the branches and leaves. After the plant matures, it can be placed in a sunny place outdoors for maintenance, pay attention to the summer should not be directly exposed to strong light, and appropriate shading measures should be carried out to avoid direct light to the osmanthus tree.

3. Watering appropriately

Osmanthus trees like a dry growth environment, the growth period of 2 3 days watering once, the summer weather is hot and the water demand is large, it is recommended to water once in the morning and evening, but the amount of water should not be too large, so as not to cause root rot due to stagnant water. Water once a day in the morning during the flowering season to eliminate and prevent the potting soil from being too wet and the flowers from falling, and the temperature can be reduced appropriately in winter when the temperature drops once in 10 days.

The osmanthus that blooms in April is the Four Seasons Osmanthus, which is a type of osmanthus.

As the name suggests, it blooms all year round, and it is a shrub-like bush with usually very low plants.

The leaves of the four seasons laurel grow symmetrically, the leaves are relatively thin, the leaf surface is very smooth, and the bark is black-brown. The twigs are cylindrical and generally hairless on the branches. The flower color of the four seasons osmanthus is white or pale yellow, the difference is that its floral fragrance is very light, and the fragrance is almost impossible to smell without intention.

Sijigui likes a moist and sunny environment, and the requirements for soil are relatively high, which is most suitable for growing in fertile and well-drained soil, and the soil must also be acidic. Sijigui has a certain ability to resist cold, but can not withstand the particularly cold climate, the temperature is best between 20-30, as long as there is no special situation of the big cold wave in winter, it can usually survive the winter.

Summary. Hello, after inquiry, osmanthus will bloom in May, but according to different varieties, the flowering time is also different, and the flowering in May belongs to: the four seasons osmanthus tree.

Hello, after inquiry, osmanthus will bloom in May, but according to different varieties, the flowering time is also different, and the flowering in May belongs to: the four seasons osmanthus tree.

Pro, the flowering time of different varieties of osmanthus is: 1. Golden osmanthus: flowering period 9 to October, golden yellow color.

2. Silver cinnamon: flowering period 9 to 10 months, the face is white or yellowish-white. 3. Dangui:

It blooms in October and is orange-red or orange-yellow. 4. Four seasons of Gui Dialect: There are a small number of flowers every month, and the most closed ears are from March to May, and the color is white.

Pro, data development: Osmanthus is not at the age of flowering, and the yard bucket will not bloom eggplant mold stool. Osmanthus has a long lifespan, generally living for decades to hundreds of years, and some even live for thousands of years, so its flowering age is relatively late.

It takes about 10 years for the sown seedlings to bloom, for the cuttings to bloom in four years, and for the grafted seedlings to bloom the following year.

Insufficient light: Placing osmanthus in a shady place for a long time is not conducive to flower bud differentiation. Overwatering:

It will produce stagnant water, and the phenomenon of rotten roots and fallen leaves will appear in the ridge holes, which will affect flowering. Do not change the potting soil: If you do not change the potting soil all year round, it will affect the absorption of nutrients.

Disease attack: Osmanthus is susceptible to anthracnose, scale insects and other pests and diseases.

1. Insufficient light

Osmanthus is a long-day plant, it needs sufficient light to bloom, if the plant is kept in a shaded position during the growth period, it will cause the leaf color to turn yellow and light, which is not conducive to flower bud differentiation, and finally it will not bloom.

2. Overwatering

Osmanthus avoid waterlogging, fiddling in its growth season or dormant period if too much watering, potting soil water, will produce the phenomenon of rotten roots and leaves, thereby affecting flowering, usually to control the amount of watering, watering frequency can not be too high, watering more on the plant in time to a cool place.

3. Do not change the potting soil

Potted osmanthus does not change the pot and soil all year round, the root system will be distorted because it cannot be stretched, affecting the absorption of nutrients, and further cherry finger has an impact on flowering, it needs to be repotted once every 1-2 years, and a small amount of hoof can be applied at the bottom of the pot as base fertilizer when changing pots.

4. Disease invasion

Osmanthus is susceptible to anthracnose, brown spot, blight and scale insects and other pests and diseases during the growth period, if not controlled in time, the leaves will turn yellow, which will also affect flowering, and it is necessary to purchase pesticides for different pests and diseases for control.

1. Insufficient light: Osmanthus has high requirements for light, and if the light is insufficient, it is difficult for flower buds to form. Only planted in a sunny and well-ventilated place, so that the ridge can fully receive the light, in order to bloom normally, if long-term shade, it is easy to cause branches and leaves to grow, affecting the formation of flower buds;

2. Air pollution: If the air pollution is too wild, it will cause no flowering and other symptoms;

3. Serious water accumulation: Osmanthus is taboo to accumulate water, which will cause root rot. Osmanthus likes high and dry terrain, well-drained sandy loam, if the soil is waterlogged, it will cause root rot for a long time;

4. Pest and disease hazards: Although there are relatively few osmanthus pests and diseases, when they are in a shady, humid and ventilated environment, they will cause disease. After the onset of the disease, it will cause the leaves to wither and fall off, and the flowers.
