What should I do if the osmanthus tree does not bloom for several years in a row?

It's clear that there's a lack of pruning. The root system of osmanthus is well developed, the germination force is strong, and it should be pruned in time to make the flowers fragrant. Generally, trees that have been raised for a long time are larger, and too much pruning will be wasted, but if there is no pruning, there will be less flowering as you said.

In fact, it can be pruned and shaped in autumn now, which is conducive to flowering next spring and autumn, and can also make the plant shape and posture plump and beautiful, and can achieve the ornamental effect from all angles, so that the branches and leaves can grow more stretched and beautiful.

In addition, copy the inside paragraph 2, why don't potted osmanthus flowers? A: First, there is not enough light.

Osmanthus likes light, and when the light intensity of the vegetative growth period is below 60, its growth and development decline, the vegetative growth becomes poor, and the number of flowers decreases. When there is a severe lack of light, flowering is not possible due to the weakening of photosynthesis and the low accumulation of nutrients. Therefore, it is necessary to give sufficient light.

The second is the lack of fertilizer. The growth and flowering of osmanthus are large and require a large amount of nutrients. Poor potting soil or insufficient fertility can also affect the growth and flowering of plants.

Therefore, nitrogen-based fertilizer should be applied 1 2 times at the time of pumping, and 2 3 times of phosphorus-based fertilizer should be applied during the flower bud differentiation stage (starting at the end of May) and before flowering. The third is that the potting soil is too wet. Osmanthus should not be too wet and waterlogged, and waterlogging will cause root rot and lead to poor growth and non-flowering, and in severe cases, it will also cause the death of potted plants.

Watering should follow the principle of "not dry, not watering, watering is watering thoroughly", after heavy rain and heavy rain to pour out the water in the pot in time, especially pay attention to the sunny weather after the rain, but also to avoid damage to the root system. Fourth, the soil is alkaline. Osmanthus prefers slightly acidic soil, and the pH value is appropriate.

Osmanthus flowers that grow in alkaline soil often do not grow well and affect flowering. Fifth, soot pollution. Osmanthus is not tolerant to smoke and pollution.

After too much smoke and dust or pollution, the leaves will become smaller, easy to fall off, and only grow leaves and do not bloom. Sixth, it is less than the flowering age.

The osmanthus tree has not bloomed for a long time? If you change it in time, it will soon blossom.

1. Excessive watering: The soil is seriously waterlogged, which leads to the rot of the root system of the osmanthus tree and the situation of not flowering. 2. Insufficient fertility:

The root system grows weakly, resulting in insufficient nutrients transported by the root system to the plant. 3. Soil overalkaline: alkaline soil affects the growth and development of roots.

4. Environmental discomfort: insufficient sunlight or claustrophobic environment hinders the photosynthesis of leaves.

1. Overwatering

Osmanthus tree does not bloom is caused by excessive watering, osmanthus tree likes a moist environment, but avoid waterlogging, if there is soil water during the maintenance period, it will cause the root system of the plant to rot, affect the transportation of water and nutrients, cause osmanthus tree to develop poorly, it will cause the situation of not flowering.

2. Insufficient fertility:

In the process of maintaining osmanthus trees, it is necessary to provide fertile soil for plants to meet the demand for nutrients for the growth and development of osmanthus trees.

3. The soil is too alkaline

Osmanthus trees are suitable for growing in slightly acidic soil, if the alkaline soil is used to maintain the plant, it will affect the absorption and transportation of water and nutrients by the root system of the osmanthus tree, resulting in poor plant growth, and then no flowering.

4. The environment is uncomfortable

Osmanthus trees have not bloomed for several years, it is caused by the unsuitable breeding environment, the plant likes ventilation, warm and humid environment, if the osmanthus tree is maintained in a claustrophobic environment with insufficient sunlight or claustrophobia, it affects the leaves for photosynthesis, resulting in poor plant growth.

Summary. Hello, osmanthus is still in the vegetative growth stage. If the planted osmanthus tree is cultivated from seedlings, it may be in the stage of nutrient production for a long time, and it has not yet reached its biological age, so it will not bloom; 2. The amount of light is insufficient.

Osmanthus trees are light-loving species, so they should not be planted in places where there is a lack of sunlight or shady sides. Even if the osmanthus tree is grafted or cut into a tree, if it does not receive sufficient sunlight for a long time after planting, the vegetative growth will be repeatedly delayed, and its flowering will be affected. If it is an osmanthus tree cultivated by seedlings, it is even more difficult to have a chance to bloom.

If the osmanthus tree has already bloomed before it is bought, it will also reverse the reproductive growth to vegetative growth, so that the original flowering plant will stop flowering; 3. The amount of phosphorus and potassium fertilizer is insufficient. If nitrogen fertilizer is applied simply or too much, it can only promote the vegetative growth of osmanthus trees and delay the flowering time. The application of phosphorus and potassium fertilizers can promote the transition from the vegetative growth phase to the reproductive phase, so that it can flower.

Therefore, for the newly planted osmanthus trees, in addition to the appropriate application of nitrogen fertilizer, more compound fertilizers containing nitrogen, phosphorus and potassium should be applied, and more phosphorus and potassium fertilizers should be applied when entering the reproductive stage. At the same time, it is also necessary to pay attention to the daily management and maintenance of pests and diseases.

Why do some osmanthus trees not bloom for more than ten years?

Hello, osmanthus is still in the vegetative growth stage.

At the same time, it is also necessary to pay attention to the daily management and maintenance of pests and diseases.

Improper selection of seedlings. Osmanthus seedlings should be grafted with mature branches of improved varieties as scion, or seedlings obtained by high-pressure method at the base of flowering branches, which are not only of good quality, but also easy to bloom after survival.

1. Soil discomfort: It affects the absorption of iron by the root system, resulting in the situation that the osmanthus tree does not bloom. 2. Overwatering:

Soil water accumulation is severe, which can lead to root rot in the plant. 3. Improper fertilization: insufficient fertilization or excessive or excessive fertilization will cause the normal physiological activities of the root system.

4. Pests and diseases: Pests and diseases will erode the branches, leaves, and flower buds of osmanthus trees.

1. The soil is unsuitable

If it is maintained in alkaline soil, it will affect the absorption of iron by the roots, resulting in poor growth of osmanthus trees and non-flowering.

2. Overwatering:

Osmanthus trees like a moist environment, but not tolerant to waterlogging, if in the maintenance process, long-term watering, will lead to serious soil waterlogging, and then plant root rot, affect the absorption of water, nutrients, transportation, resulting in poor growth of flower buds, unable to flower.

3. Improper fertilization

In the process of maintaining osmanthus trees, if the proportion of nitrogen fertilizer is too high, there will be branches and leaves growing, consuming a lot of nutrients, so that the nutrients provided for the growth and development of flower buds are insufficient, and the plants can not bloom normally.

4. Pest and disease infestation

If the osmanthus tree is infected with leaf spot, black rot, aphids and other pests and diseases, it will affect the flowering of the plant, such pests and diseases mainly damage the branches and leaves, flower buds, etc., the infected part slowly wilts and falls off, and in severe cases, the osmanthus tree wilts and dies.

The osmanthus tree can bloom for a few years after planting is not fixed, it should be determined according to the method of propagation, and the method of different growth conditions is not used, and the flowering can be different in a few years. Among them, the seedlings sown and propagated have the longest maintenance time, and generally do not grow for a long time, and usually take about 10 years. The second is propagation by cuttings, and the cuttings are generally raised for about 4 years after planting.

The grafted seedlings are the fastest in flowering halls, and many can bloom in the same year, but the number of flowers is relatively small.

1. Supplemental light: It prefers light, and if it is placed in the shade for a long time during the growth period, it will not bloom. It should be moved to a place with good light in time, let it bask in the sun more, and the light will bloom when it is full of flowers.

2. Scientific application of fertilizer: more nutrients are consumed in the growing season, and fertilization should be applied frequently, so that the nutrients can grow more vigorously and prepare for flowering. Before flowering, the amount of nitrogen fertilizer should be reduced, and more phosphorus and potassium fertilizer should be applied, so that the flower buds can be better differentiated and promote flowering.

3. Reduce watering: Reduce the amount of water before flowering. If you water a lot, the water will affect the flowering, and it is easy to lead to the phenomenon of growing but not flowering. Water should be properly controlled, and the soil should not be watered first if it is not dry.

1. Sowing seedlings: If it is an osmanthus seedling cultivated by the sowing method, then it needs to grow for about 10 years before it can bloom normally.

2. Cuttings seedlings: Cuttings can bloom slightly faster. After about 4 years of cultivation, it has the ability to bloom.

3. Grafted seedlings: Grafted seedlings are the fastest flowering. Generally, it will be able to bloom in 1-2 years after grafting. In addition, if the grafted is an easy-to-bloom variety such as the four seasons, it may bloom that year.

1. Insufficient light: It prefers sunlight and needs to receive a certain amount of sunlight and accumulate a certain amount of nutrients before it can bloom. If you do not receive sunlight for a long time during maintenance, you may not be able to bloom.

At this time, as long as you transplant it to a place with better light conditions, and slowly maintain it for a while, it will be able to bloom again.

2. Improper fertilization: Before it enters the flowering period, it cannot be without fertilization, nor can it only apply nitrogen fertilizer, otherwise it may not be able to flower. At this time, as long as the nitrogen fertilizer is stopped and some phosphorus fertilizer is applied every 10-15 days, it will be able to bloom soon after.
