Every flower of the rhododendron is empty and implicit, picturesque and beautiful, which makes people linger. Plant a pot in the balcony, when it is in full bloom, red flowers bloom all over the balcony, bright and dazzling.

So, what problems do flower friends need to pay attention to if they want to raise cuckoos well?

1. Soil

Azaleas like fertile and well-drained sandy soil, resistant to barren soil, but do not be alkaline. It is generally cultivated to change the basin every two years to add new nutritious soil.

2. Temperature

Azaleas like warm, slightly dry and sunny environments. The suitable temperature for growth is 18: 24 ℃ from March to July, 13: 18 ℃ from September to March of the following year, and the winter temperature is not lower than 10 ℃. It is necessary to move indoors in winter and keep the room temperature above 5 ℃. If the room temperature is kept at 15-20 ℃, it will blossom continuously. It can be moved to outdoor maintenance after the beginning of spring.

3. Fertilization

Cuckoos prefer fertilizer, but require thin fertilizer to be applied frequently. Generally use diluted organic liquid fertilizer, diluted and watered once a week. From early spring to flower bud, it was applied every 10 days, the concentration was 500 times, a total of 2-3 times, to promote the old leaves to turn green and sprout new roots. The flowering period is generally not fertilized. After the flowers fade, in order to promote the growth of branches and leaves, fertilize 5-6 times from mid-May to early July. If it rains continuously, dry fertilizer can be applied. Stop fertilizing in winter.

4. Lighting

Azaleas are light-loving plants. During the growing period, there must be enough sunshine for the leaves to be green and shiny and the flowers to be bright. If you grow in the shade for a long time, the leaves will turn yellow and fall off.

5. Moisture

Cuckoo maintenance, avoid dampness and fear of waterlogging, basin soil watering should not be too much, too wet affects growth and development. In particular, indoor winter plants should be strictly controlled watering, it is better to dry, otherwise it is easy to freeze. Open field cultivation, pay attention to timely drainage after midsummer showers, in order to maintain a humid environment.

The day turns cool gradually in autumn, which is the adaptive period for the growth of rhododendron. In order to prevent autumn shoots from being pulled out and enhance the cold resistance of overwintering, the amount of water should be reduced appropriately, generally watering once every other morning to keep it moist. The cuckoo has entered the dormant period in winter and does not require much water. It is generally watered every 4-5 days, which should be carried out around noon on sunny and warm days. It can be watered appropriately depending on the drying condition of the basin soil.

6. Pruning

In order to accelerate the formation of skeleton, rhododendron seedlings in 2 ~ 4 years often pick buds and hearts to promote the germination of lateral branches. After growing into a big tree, it is generally allowed to grow naturally and is only reshaped after flowering, mainly by cutting off overgrown branches, diseased and weak branches, deformed branches and damaged branches. Apply a protective agent to the wound after trimming to make it heal quickly.
