Five diseases of rhododendron can bloom early in order to prevent the bud early.

Azaleas, red flowers blooming, very spectacular. If it is well maintained, the basin can be filled every year. However, in the process of conservation of rhododendron, it is easy to encounter these five diseases, flower friends need early prevention, so that rhododendron can bloom early.

Rhododendron needs to consume a lot of nutrients when it blossoms, so flower friends should apply more phosphorus and potassium fertilizer before flowering, generally using organic nutrient solution and watering 500 times of water, which can make the bud full and the bud will not wilt. Don't apply too much nitrogen fertilizer.

In the conservation of cuckoos, there are many causes of cuckoo death, mainly in the following ways:

1. Soil damage

Azaleas prefer acidic soil to alkaline soil. Most of the soils in the north are alkaline or nearly neutral. Using this soil as culture soil to cultivate rhododendron will inevitably lead to poor plant growth, yellow flowers, dry branches and death over a long period of time. Therefore, to cultivate cuckoos, flower friends need to choose loose ventilation, good drainage, can add the right amount of ferrous sulfate.

2. Water damage

Because the roots of cuckoos are slender, and some lateral roots are as thin as hair, they are afraid of both dryness and waterlogging. If the water is too little, the leaf color will turn yellow, and when the whole plant is serious, the whole plant will die; if the watering is too much, the basin soil will be too wet for a long time, which can easily lead to root rot. It is best to use Rain Water to water cuckoos, followed by river water and pond water. Watering with a uniform spray can, dry and thoroughly watered.

3. Fertilizer damage

Azaleas are afraid of thick fertilizer and raw fertilizer. If fertilizing too heavily or adding rotten eggs, bean cakes, fish offal, chicken and duck manure and other unfermented raw fertilizer, it will cause "root burning" and cause the plant to wither and die. Especially in the hot summer season. Therefore, flower friends are advised to fertilize the cuckoo, to use thin liquid fertilizer, organic nutrient solution is more suitable for cuckoo root absorption, 500 times water, directly irrigate the root, once a week.

4. Root damage

Potted cuckoos have not changed pots and soil for many years, resulting in roots densely spread in the basin and tangled together, lack of nutrition, resulting in weak growth of rhododendron plants, which will also cause plant death if it goes on like this for a long time. Therefore, cuckoos need to change their pots every 1-2 years.

5. Cold injury and high temperature injury

Azalea is easy to be injured when it is lower than 5 ℃ or higher than 35 ℃, especially the hot and muggy summer often causes rhododendron yellow, fallen leaves, and even death, and early spring is also one of the causes of rhododendron death. Therefore, cuckoo maintenance needs to be maintained at 18-25 ℃, and it is recommended to leave the room after Qingming Festival.
