This is iron deficiency, because rhododendron likes acidic soil, and ordinary soil is lack of acidic substance, so we should regularly water rhododendron with ferrous sulfate, the proportion is 1VR 1000, and supplement it once a month, which can effectively prevent the occurrence of yellow leaves of rhododendron.

2. stagnant water in flowerpot

If the soil in the flowerpot is impervious and stagnant water, it is easy to cause the azaleas to turn yellow, rot and lose their leaves, because the roots of azaleas are very weak capillaries and have no main roots. We must pay attention to watering, do not accumulate water, and if there is water in the receptacle, it must be poured out, otherwise the roots will rot.

If this happens, it should be irrigated with carbendazim solution, which can be irrigated or sprayed with a ratio of 1 to 500. Spraying once a week, two or three times can effectively prevent and cure it.

3. Lack of fertilizer

The cuckoos of many of our friends are prone to yellowing and shedding of old leaves and yellowing on both sides of new leaves after flowering. In fact, this is a lack of nutrition, that is, fertilization can not keep up with normal times, especially after flowering, consuming a lot of nutrients. If fertilization is not applied in time, the leaves will turn yellow.

At this time, we should cut off the residual flowers and add nitrogen fertilizer to it. We should let it grow branches and leaves, and apply it every half a month. If we apply thin fertilizer frequently, the cuckoo can grow well.

4. The cuckoo likes the warm and humid environment, so we should pay attention to increase the air humidity at ordinary times. If the air humidity is not enough, it is easy to cause all kinds of yellow leaves and dry tips. You can spray water around the flowerpot or spray water on the back of the leaves to increase the air humidity. Be sure to maintain good ventilation.

Don't be exposed to the sun in summer, other seasons can be placed in a semi-overcast or astigmatic environment, so if the cuckoo yellow leaves rotten roots, just water and add some ingredients, it will be green in a few days.
