Rhododendron culture

Azaleas are very beautiful, and everyone is willing to raise them, but how can they raise them well? There are many fastidious here, azaleas like acidic soil and water, afraid of alkaline soil and water, afraid of waterlogging: like warm and cool, afraid of dry and hot environment, afraid of dry air; like semi-overcast, afraid of scorching sun; like thin fertilizer, afraid of thick fertilizer. What kind of soil larch humus soil acidity is suitable, soil quality is loose, fertile, good permeability, suitable for rhododendron growth.

What kind of water should be used for cuckoos? the PH value is less than 7. In areas where the water quality tends to be alkaline, in addition to storing Rain Water and snow water, acidified water can be used, that is, 100 jin of water plus 0.1% ferrous sulfate for perennial use. If the acidity is not enough, you can supplement it with less vinegar. How to water:

(1) "trapped water" should be used, that is, the water and the cuckoo should be dried at the same temperature. Fish tank water, Rain Water, river water can also be used.

(2) if the soil is not dry or irrigated, it should not be too dry, and the leaves will wilt if it is too dry.

(3) Water must be thoroughly watered.

(4) there are differences between winter and summer. The leaves are good in winter, but it doesn't hurt to get wet in summer. Flowering period should not be more watering, too much easy to drop buds and early thanks; spring and autumn wind is dry, must be sufficient.

Pay attention to spraying leaves and ground, maintain a certain humidity, the amount of fertilizer used for azaleas is lighter than that of other flowers, the general rule is: fertilizing in growing period, not in dormant period, fertilizing in prosperous period, but not in diseased plants, fertilizing when leaf buds are active, but not fertilizing when inactive.

What fat is good? Acidity and low alkalinity are better, which requires mild fertility and long fertilizer effect, as well as high contents of nitrogen, phosphorus and potassium. Such as bean cakes, soybeans, sesame sauce dregs, rice washing water, horseshoe slices, meat washing eggs, milk, sheep dung and so on all contain nitrogen, phosphorus and potassium.

The legend of the cuckoo crying blood the cuckoo is commonly known as Bugu, also known as Zigui, Zijuan. In spring and summer, the cuckoo keeps singing all night, which is clear and short, evoking a variety of feelings. If you take a closer look, the cuckoo's oral epithelium and tongue are red, and the ancients mistakenly thought it was bleeding all over its mouth. when the cuckoo was singing, it was when the azaleas were in full bloom, and when people saw the azaleas as bright red, they described this color as the blood of the cuckoos. Just as Cheng Yanxiong, a poet of the Tang Dynasty, wrote, "azaleas and birds, resentment and glamour can not be trusted, suspected to be blood in the mouth, dripping into flowers on branches."
