1、 Flowering period of Rhododendron

Azaleas bloom in both spring and summer. For people who want azaleas to bloom in winter, they can choose controlled plants. The Rhododendron flowering in winter is western Rhododendron. This kind of Rhododendron grows mostly in greenhouses and greenhouses. Its flowering period is artificially controlled. Generally, it opens before the Spring Festival and ends in April next year. The most suitable environment for Rhododendron is ventilation, humidity, semi shade and warmth. Therefore, people who want azaleas to bloom in winter need to maintain them according to their different environments. The Rhododendron can adapt to the outdoor temperature in the south. Because the temperature in the north is too cold, the azaleas must be placed indoors and bloom before and after winter. They can open two or three times a year

2、 Regulation of Rhododendron

1. Soil treatment

Loose, fertile and acidic loess is better. The planter can plant azalea in the mud basin, because the mud basin is more breathable and conducive to the growth and development of roots. Do not use human feces when fertilizing. You can add flower fertilizer to the pot once or twice a month. Remember to strictly control the amount of fertilizer. If the fertilizer is too heavy, the plants will be burned

2. Temperature treatment

The most suitable living environment temperature for Rhododendron indoors is 10 to 25 degrees. Because Rhododendron likes semi cloudy environment, it is not allowed to direct the sun excessively in summer and too low in winter

3. Moisture treatment

The Rhododendron has few thick heels and a large number of small rhizomes. The Rhododendron needs an appropriate amount of water, not too much or too little. If too much, plant roots will be soaked in water for a long time. If there is too little, the plant will be in the state of water shortage for a long time, and the normal activity of the plant cannot be guaranteed

4. Light treatment

The Rhododendron needs an appropriate amount of sunshine. Direct sunlight should be avoided in summer and the absorption of sunlight should be strengthened in winter. For the Rhododendron cultivated in pots, it would be better if it could be placed on the balcony with weak sunshine

5. Precautions

Only the growth environment required by Rhododendron can meet the requirements. If you want Rhododendron to bloom in winter, you need to pay attention to the following four aspects: in hot summer, the ultraviolet ray of the sun is too strong, which is not conducive to the growth of Rhododendron. In the cold winter, we didn't pay attention to the impact of temperature on Rhododendron, resulting in frostbite, watering too much water and applying too much fertilizer
