    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.

    The reason why rhododendrons shed their leaves.

    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 in which the rhododendron is cultivated is deficient in the element iron.

    will hinder chlorophyll.

    The result is that the leaves are yellowish-white, and the young leaves that have just grown are more pronounced, which is also the reason why the azaleas lose their leaves if they persist for a while.

    3. Poor ventilation.

    The reason why the rhododendron loses its leaves is that the root system of the rhododendron is very slender, if the potting soil is loose and the air permeability is not good or the long-term watering is too frequent and the ventilation is not good, the root system of the rhododendron will be damaged, causing the azalea leaves to be sluggish and fall off.

    Rhododendron dry leaves may be soil discomfort, it has high requirements for soil, especially the pH of the soil, like acidic soil, if the soil is heavy alkaline will hinder growth, easy to have yellow leaves, dry leaves, defoliation.

    It is necessary to change the soil as soon as possible, or pour ferrous sulfate to improve the soil quality, or there may 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, and fertilizing it must be carried out in accordance with the thin fertilizer application method.

    Rhododendron planting:

    Rhododendron is most suitable for planting in early spring or late autumn, such as planting in other seasons, must be erected shade canopy, planting must make the root system and soil even, but not too compact, and make the soil surface near the rhizome in an arc-shaped state, so that the superficial root system of the plant can be protected from severe cold frost damage, and is conducive to drainage.

    Generally, in spring and autumn, rhododendrons planted in the open field can be watered once every 2-3 days, and at least once a day in the hot summer. Daily watering, do not use alkaline water, watering should also pay attention to the water temperature should not be too cold, especially in the hot summer, with supercold water water, resulting in a sudden decrease in soil temperature, affecting the root system water absorption, interfering with the physiological balance of plants.

    The dried leaves of the azalea may be caused by the excessive alkalinity of the soil, so it is necessary to replace it with a soft and breathable slightly acidic soil in time. If you do not water for a long time during the growth of azaleas, it will also cause the azaleas to dry up and lose their leaves.

    The loss of leaves from rhododendrons can be caused by soil discomfort, which has a high demand for soil and is suitable for growing in slightly acidic soils. If the soil is too alkaline, it will affect the germination of rhododendron branches and leaves, and there will be poor growth. At this time, it is necessary to change the soil in time and replace it with a soft and breathable slightly acidic soil, so that the azalea can recover as soon as possible.

    Rhododendron is suitable for growing in a humid environment, but it is less tolerant of waterlogging. If you do not water the azalea for a long time during the growth period, it will cause the leaves to turn yellow and fall off, dry up or even fall off. Overwatering can also cause the azaleas to not be able to absorb water, and the root will be rooted.

    Every time you water your azaleas, make sure the soil is slightly moist.

    Improper fertilization can also cause rhododendrons to appear as flowers dry out of leaves. Rhododendron consumes a lot of nutrients during the growth period and needs to be supplemented in time. However, if you apply too much fertilizer at one time or the concentration of fertilizer is too high, it will be costly, and you need to water as soon as possible to dilute the fertilizer in the soil.

    In severe cases, it is necessary to repot and plant.

    Environmental discomfort can also cause rhododendrons to dry up their leaves. During the growth period of rhododendrons, it is necessary to give an appropriate amount of upper light, and control the ambient temperature between 15 and 20 to ensure that the temperature is constant. In order to make the rhododendron grow vigorously, when the light is too strong, it needs to be shaded to avoid high temperature burn leaves.

    There are two reasons for the yellow leaves and dead leaves of rhododendrons, one is that the sun is too much and the rhododendron loses too much water; The second is that the rhododendron is not completely potted, and the transpiration is large, and the rhododendron will protect itself by shedding leaves out of self-preservation.

    Rhododendron is an evergreen shrub and deciduous shrub of the class Dicotyledons, Rhododendron family, and Rhododendron genus. Lack of sufficient nutrients during the growth process, some parts of the rhododendron are not well developed, which will lead to problems such as yellowing of leaves, rotten leaves, and wilting leaves.

    Attacks such as leaf spot, leaf blight, and stem rot can cause the leaves of rhododendrons to turn yellow.

    Sometimes, when azaleas are attacked by pests and diseases, the leaves will turn yellow and wilt. Generally, the yellowing of rhododendron leaves is caused by insufficient nutrition. Recommendations:

    Top dressing outside the roots. Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied. Extra-root fertilization is to spray the dilution of fertilizer directly on the leaf surface of the plant with a mist, so that the nutrients can penetrate into the leaf tissues through the leaf epidermal cells and stomata, and then be transported to the whole body of the plant.

    It is recommended to use Bayliss moon plants to spray the foliar surface of azalea regularly, the nutrient absorption is faster and more sufficient, and the leaf spot, leaf blight, stem rot and other diseases of the rhododendron are removed, so that the rhododendron is fully nutritious and no longer yellows and withered leaves, and has the effect of promoting flowering and flowering.

    Regular use of Bayliss moon plant care can also prevent the occurrence of leaf spot, leaf blight and stem rot, and ensure that the leaves are green and the flowers are gorgeous.
