Why do the leaves of rhododendrons grow luxuriantly, but the flowers always wilt?

Upstairs is not right, in my years of experience in raising rhododendrons, the problem is that "the leaves of the azalea grow very lushly", you have never pruned the branches of the rhododendron, this is not good, most of the organic matter and inorganic salts synthesized by the plant are supplied to the branches, not supplied to the flowers, so it will happen that "the leaves grow very lush, but the flowers are always withered", plastic pruning to accelerate the blooming of the plant, the rhododendron often promotes new branches through topping, for the flower clusters, affecting the flower shape can be early to thin the buds, This not only makes the flowers big and fresh in the current year, but also helps the plants grow and bloom in the next year. Rhododendron germination is strong, and the branches seriously affect the growth and development of the plant, reducing its ornamental and commercial properties, so it needs to be adjusted by pruning. Pruning is generally carried out after flowering in spring and autumn, and pruning dead branches, oblique branches, long branches, diseased and insect branches and some cross branches are cut off to avoid nutrient consumption and make the whole plant bloom plump.

Rhododendron wilts? Pay attention to these two "reasons", the branches and leaves are thick green all year round.

Why is the belly cuckoo leaf trade sheng without flower buds, and if there are flower buds, they are dry.

Rhododendron dry leaf loss may be a soil problem, which is demanding on the soil, especially the pH of the soil. Prefer acidic soil, if the soil used is alkaline, it will hinder growth, and it is easy to have yellow leaves, dry leaves, and leaf loss. It is necessary to change the soil as soon as possible, or pour ferrous sulfate to improve the soil quality.

It may also be a lack of water or too much watering. If there is a shortage of water, replenish water as soon as possible, and drain water when there is too much water to evaporate the water. It may also be that improper fertilization has caused fertilizer damage.

Fertilizing it must be carried out in accordance with the thin fertilizer application method.

First, the soil is unsuitable.

The dry leaves of rhododendrons and the loss of leaves are most likely caused by soil discomfort, which has high requirements for the soil, especially the pH of the soil. Prefer acidic substrate, if the soil used is too alkaline, it will affect the germination of branches and leaves, and it is easy to have various poor growth conditions, such as leaves will be yellow, dry up, and fall. As a result of this situation, it is necessary to change the soil as soon as possible and replace it with a soft, breathable, acidic matrix.

If the climate is not conducive to changing pots, ferrous sulfate can be poured to improve the soil condition and promote recovery as soon as possible.

2. Improper watering.

Rhododendron prefers moist environments, but is not tolerant of waterlogging. If you don't water for a long time during the maintenance period, the soil will be dry and waterless, and the leaves will be prone to yellowing, drying, and even falling. Or it is not good to water too much, the water cannot be absorbed, and after a long time, there will be stagnant water, roots will be soaked, and leaves will also fall.

If you are short of water, replenish water as soon as possible to moisten the soil. If there is stagnant water, stop the water first, drain it as soon as possible, strengthen ventilation, and evaporate the water.

3. Improper fertilization.

The loss of dried leaves of rhododendrons can also be caused by improper fertilization. It consumes a lot of nutrients during growth and needs top dressing. However, if the fertilizer is too much or the concentration of fertilizer is too high, the roots will be burned and the leaves will dry up and fall.

Water should be poured as soon as possible to rinse off the fertilizer. If the situation is severe, it is necessary to remove the pot, trim the roots, and replant. Note that fertilizing it should be carried out with thin fertilizer and frequent application, so that it can absorb nutrients well and avoid fertilizer damage.

You see, if there is not enough water, if the water is too big, it will wither and lose its leaves.

Plants, like animals and humans, have a life cycle, and the withering and falling of flowers and leaves is a natural phenomenon of life.

It is not uncommon for rhododendron leaves to dry up, mainly due to low watering, excessive fertilizer, scorching sun exposure, and poor temperature and humidity. In addition, diseases and insect infestations can also cause leaf drying, which is rare but real. Next, we will start from the cause of the wilting of azalea leaves to find corresponding solutions.

1. Improper watering.

Too dry an environment is very detrimental to the growth of rhododendrons, after all, the demand for water is not low. Therefore, when the leaves of the rhododendron dry up due to lack of water, we must pay attention to the timely supply of water. Note that watering the rhododendrons is not as much as possible, just dry and wet.

Whether the soil is dry for a long time or there is standing water, it is not conducive to the normal growth of the plant.

2. Improper fertilization.

Any plant needs a supply of nutrients in the process of growth, and rhododendrons are no exception. The nutrients of the rhododendron not only depend on their own absorption, but also need to be fertilized at the right time and in the right amount. However, many flower friends often cause rhododendrons to burn their roots due to too much fertilizer when fertilizing, so the leaves dry up.

Therefore, we must pay attention to the control of the amount of fertilization for rhododendrons, and apply thin fertilizer frequently, which can not only ensure that the fertilizer nutrients are sufficient but also will not burn the roots due to the large amount. Don't panic if there is too much fertilizer, change the soil or dilute the roots in time, and clean up the excess fertilizer in time to improve the growing environment.

3. Exposure to the scorching sun.

Light conditions are essential for the growth of plants, and lack of light is easy to breed bacteria. However, it should be noted that when exposed to sunlight, the rhododendron may be burned and the leaves will dry up. Therefore, sunlight should be properly shaded under the scorching sun.

4. The temperature is uncomfortable.

Rhododendron generally grows best between 15-30 years old, with high temperatures in summer causing the leaves to dry out, and temperatures too low in winter affecting their growth.

Therefore, in the summer season, it must be shaded and ventilated, and the humidity can be increased by spraying to control the temperature. Keep warm during the cold winter months to prevent frostbite.

Rhododendron will wilt and lose leaves, which has a lot to do with the soil you breed or daily maintenance, as well as the weather.

Rhododendron has extremely high requirements for temperature and humidity, and if it does not meet certain standards, it will affect the growth of azaleas and cause the leaves to dry up. Rhododendron loves the sun, and if you don't see sunlight for a long time, the leaves of the azalea will start to dry up.

Salinity, drought, dampness, root rot, dry rot, net bugs, nutrient deficiency, etc.

Flowers bloom and fall from time to time, and so do azaleas.

1. The reason for the wilting and loss of leaves of rhododendrons.

1. Soil pH.

Many flowers prefer acidic soils, and so do azaleas. If the azalea is allowed to live in alkaline soil and no timely measures are taken, the rhododendron leaves will turn yellow and dry up, which is why the azalea loses its leaves.

2. Lack of iron in the soil.

If the soil where the rhododendron is cultivated is deficient in iron, the synthesis of chlorophyll will be hindered, resulting in yellowish-white leaves and more pronounced young leaves.

3. Poor ventilation.

Another reason why rhododendrons lose their leaves is that because the root system of azaleas is very slender, if the potting soil is loose and the air permeability is not good or long-term watering is too frequent and too often, coupled with poor ventilation, the root system of the azalea will be damaged, causing the rhododendron leaves to be sluggish and fall leaves.

Second, the solution.

1. The culture soil of rhododendron must be made of acidic soil with good loose air permeability and rich decay, and the pH value is the best. Usually apply some alum fertilizer water, or add a little ferrous sulfate to the water, so as to avoid the dry and fallen leaves of rhododendrons.

2. Although azaleas like sunlight, they are afraid of direct sunlight, and although they like a ventilated environment, they cannot be molded in a strong wind. In summer, it should be placed in a shaded place, properly exposed to astigmatism, and in spring and autumn, it should not be placed in the wind outlet, and the azalea should be placed in a sunny and sheltered place in the morning and evening.

3. Many planted azaleas generally end their flowering period around the Spring Festival, and the branches and leaves will dry up, which is a normal phenomenon.

1. Shade: Rhododendron leaves are yellow, and shade nets need to be built above the plants for shade. 2. Temperature:

Rhododendron is neither cold nor heat tolerant and needs to control the ambient temperature at around 20 degrees. 3. Watering: Wait for the surface of the soil to turn white before watering to avoid rhododendron rot roots.

4. Fertilization: Apply well-rotted organic fertilizer to the rhododendron to make it grow new leaves.

1. Block strong light

Rhododendron leaves wilt, it is likely to be caused by too much light, it likes to grow in a semi-shady environment, is a plant that is not tolerant to strong light exposure, so at this time it is necessary to shade the strong light, it is best to move the plant to a place with scattered light to maintain, so as to improve its wilting phenomenon.

2. Suitable temperature

Rhododendron likes a cool climate environment, its optimal growth temperature is about 20, if the temperature is too high or too low, the rhododendron leaves will wither, so we need to do a good job of temperature control measures for it, in summer to maintain it in a cool and ventilated place, in winter to move to a warm place indoors to maintain.

3. Reasonable watering

Rhododendron leaves appear wilting, and may be caused by too much or too little watering, it likes moisture, but is not resistant to waterlogging, so at this time we should water it reasonably, it is best to water it according to the dryness and humidity of the soil, keep the soil slightly moist, pay attention to the use of alkaline water when watering.

4. Correct fertilization

Rhododendron leaves appear wilting, it may also be caused by improper fertilization, it is a fertilizer-loving plant, but can not be applied to it raw fertilizer or thick fertilizer, at this time we had better replace it with new soil, and then fertilize to apply rotten fertilizer, but also to master the principle of thin fertilizer diligent.
