This paper introduces the morphology, living environment and living habits of rhododendron.

Rhododendron buds are oval, with coarse hairs on the middle and top of scales and eyelashes on the edges. Flowers form two or three clusters at the top of branches. Pedicel 8 mm long, densely covered with bright brown coarse hair.

Calyx is divided into five parts, lobes are triangular and rectangular, five millimeters long, with coarse hair and eyelashes at the edge. Corolla is funnel-shaped, rose-colored, bright red or dark red, 3.5 to 4 cm long and 1.5 to 2 cm wide.

2. The living environment of rhododendron:

Rhododendron is born in mountain shrubs or pine forests at an altitude of 500 to1200m. It likes acidic soil, and it doesn't grow well even in calcareous soil.

3. Life habits of azaleas:

Rhododendron likes a cool, humid and ventilated semi-cool environment, and is afraid of both heat and cold. The suitable temperature for growth is 12℃ to 25℃. When the temperature exceeds 35℃ in summer, the new shoots and leaves grow slowly and are in a semi-dormant state.

Extended data:

Rhododendron is a flower that tends to rely on acidic soil, so it must be planted in acidic soil. Peat soil, garden soil and sand can be mixed according to the ratio of 5: 3: 2 to make them suitable for the growth of rhododendrons, and try to choose acidic soil with ventilation and drainage and loose fertility.

Rhododendron doesn't like shade, so it is necessary to provide sufficient light for Rhododendron during cultivation. But in summer, we need shade to prevent rhododendrons from getting sunburned, and in other seasons, we should put rhododendrons in places with strong light, so that they can bloom more beautifully.

When raising azaleas, pay attention to micro-fertilizer, increase the number of times, and properly supplement nutrients for them to make them grow vigorously. However, the root system of rhododendron is not very strong, and only fertilization is needed without thick fertilizer or raw fertilizer, which is easy to cause root rot of rhododendron and the whole plant is likely to die.
