Four suitable taboos of rhododendron

Rhododendron, also known as azalea, belongs to Ericaceae, is a typical acid indicator plant. Because of its colorful, flower-type strange, flowering longer, different varieties, often loved by people. However, due to improper management methods, resulting in less yellow leaf color, or even death. Therefore, special attention should be paid to the "four advisable and four taboo" in peacetime management.

First, it should be warm and humid to avoid the hot sun too wet. Rhododendron should grow in a warm and humid environment, should keep the basin soil moist, but can not accumulate water, accumulated water easy to cause rotten roots lead to death. If pouring tap water should be added to the right amount of vinegar or ferrous sulfate, so that the water is acidic and then poured. If the rice water and water washing fish, meat, etc. must be fermented smell sour diluted after watering its roots. Every watering should wait until the soil dries before watering. Summer temperature is higher, in the hot sun, tender leaves are easy to burn; and its roots are close to the soil surface, vulnerable to dry heat damage, shade should be carried out to prevent leaves from becoming yellow and dry and affecting growth and viewing.

Second, it is appropriate to apply thin fertilizer frequently and avoid thick fertilizer. Azalea root thin and shallow, fertilizer should be liquid fertilizer, fertilizer should be fermented bean cake fertilizer, chicken manure and other water irrigation, once a week, too much fertilizer is too thick to burn the root system easily lead to the whole plant wither and die.

Third, it is appropriate to avoid sticking. Rhododendron like acid soil, avoid alkaline soil containing lime and clayey soil with poor drainage, soil too sticky easy to harden water, not conducive to growth, it is better to use loose humus soil. In summer, the surface of the basin soil should be covered with decomposed organic soil as a ground cover to enhance water storage, prevent overdrying, and reduce the soil temperature to protect the roots and promote the growth of rhododendron.

4. Acid should be avoided alkali. Because rhododendron belongs to acid indicator plant, it is sensitive to soil acidity and alkalinity. Therefore, whether it is watering, fertilization, or replacement pot soil should be acid-based, avoid watering alkaline water alkaline fertilizer.
