Rhododendron language: prosperity, auspiciousness, tenacity and optimism, and prosperous career. There is a cloud in "Grass Flower Spectrum": "If Yingshanhong grows all over the top of the mountain, its year will be rich and stable, and people will fight for it."
The west also has a special hobby for azaleas. They think that the richness of azaleas is a good sign of "good luck and prosperous business", especially the all-red azaleas.
For the white cuckoo, it is considered beautiful and refined, and the mutual gift between men and women is more elegant. For red and white azaleas, the meaning is deeper, indicating: I hope to be integrated with you and create a better tomorrow.
Extended data:
land
Rhododendron is a shade-loving plant, and direct sunlight is not good for its growth. Therefore, it is best to choose a shady place, or take this into account when designing greening, and deliberately arrange trees in a special garden. Rhododendron likes acidic soil with good drainage.
However, all characteristic gardens and landscapes need to use cement as roads and pavements, and the soil in the rhododendron planting area is alkaline, so it is necessary to replace the soil in the planting area and add a certain amount of peat soil. North of the Yangtze River, potted plants are used for viewing. Potted soil consists of humus soil, sandy soil and the same soil (7:2: 1) mixed into cake fertilizer, manure and so on. , stir well and plant. Generally, change pots or soil in March in spring.
The area south of the Yangtze River is mainly planted in the ground, which should be planted before germination in spring. The place should be in a ventilated and semi-cool place. The soil should be loose and fertile, rich in humus, and acidic sandy loam is suitable, and it is not suitable for water accumulation, otherwise it is not conducive to the normal growth of rhododendrons. After planting, be sure to water it.
plant
Rhododendron is most suitable for planting in early spring or late autumn. If it is planted in other seasons, a shade shed must be built. When planting, the roots and soil must be uniform, but not too tight, and the soil surface near the roots is in an arc state, which can not only protect the superficial roots of plants from freezing damage, but also facilitate drainage.
temperature
Move out of the greenhouse in the middle and late April, first put it in the lee of the sun, cool in summer, or put it in the shade under the tree to avoid direct sunlight. The suitable growth temperature is 15-25℃, and the highest temperature is 32℃. From mid-June, autumn, 10 is moved indoors, and it is placed in a sunny place in winter. The room temperature is kept at 5- 10℃, and the lowest temperature cannot be lower than 5℃, otherwise it will stop growing.
water
Rhododendron requires the soil to be wet, not wet. Generally, in spring and autumn, cuckoos planted in the open field can be watered once every 2-3 days, and in hot summer, at least once a day. Do not use alkaline water for daily watering, and pay attention to the water temperature not to be too cold when watering, especially in hot summer, when watering thoroughly with cold water, the soil temperature suddenly drops, which affects the water absorption of roots and interferes with the physiological balance of plants.
After planting and soil improvement, water 1 time to make the roots fully contact with the soil, which is beneficial to the survival and growth of the roots. Pay attention to watering during the growth period, and gradually increase the amount of watering from March, especially in summer, always keep the basin soil moist, but don't accumulate water. Reduce watering after September, and then water after entering the house in winter.
humidity
Rhododendron likes the environment with high air humidity, but some Rhododendron gardens are built on both sides of squares and roads, and the air flows quickly and is relatively dry. It is necessary to spray water on Rhododendron leaves or the surrounding air frequently to keep the air around Rhododendron gardens moist.
Fertilize soil or land
At the end of winter and the beginning of spring every year, it is best to apply some organic fertilizer as base fertilizer to Rhododendron Garden. After the azalea blooms in April-May, because the plant consumes a lot of nutrients during the flowering period, with the germination of leaf buds, new buds are taken out and fertilizer can be applied every 15 days. After lodging, most branches have stopped growing. At this time, it is in the high temperature season, and the physiological activity is weakened, so topdressing can be stopped.
After autumn, the climate is getting cooler and there is autumn rain, and the temperature and humidity are suitable for the growth of azaleas. At this time, topdressing can be carried out for the last time, and fertilization is generally not suitable after winter.
Rational fertilization is the key to raising rhododendron, and it is preferable to fertilizer. During the spring and autumn growing season, 10 times liquid water of pancake fertilizer should be applied every 1 0 day, which can be fermented with rice washing water, peel and vegetable leaves. In autumn, you can supplement some phosphorus and potassium fertilizers, and you can use fish and chicken viscera and meat washing water, rice washing water and some peels.
In addition to the homemade household fertilizers mentioned above, you can also buy some household fertilizers to use, but remember to apply them "thinly". Apply dry fertilizer 1 time (small amount) before winter, and don't apply base fertilizer when changing pots. In addition, when watering or fertilizing water, tap water should not be used directly, but should be acidified (adding ferrous sulfate or vinegar) and then used when the pH value reaches about 6.
