The latest culture methods and matters needing attention of rhododendron

Azalea is one of the ten famous flowers in China, also known as azalea, pomegranate, luxuriant and gorgeous color, is an excellent ornamental flowers, loved by many people. But it's delicate. It's a difficult flower to grow. So, how do we grow it? What are the precautions for farming? Let's take a look at the details below.

breeding method

1. Selection of basin soil

The flowerpots for cultivating rhododendrons are mostly clay pots and purple sand pots. The clay pots have good air permeability and are used for seedling growth and cultivation. The purple sand pots have beautiful appearance and are used for forming cultivation, which can improve the ornamental value. Azalea like loose fertile weak acid soil, not heavy viscosity, poor permeability of alkaline soil, available leaf soil, peat soil and garden soil preparation of culture soil, pot can be added to a small amount of bone powder, in order to increase the minerals in the soil.

2. Temperature

Azalea's best growth temperature is 12-25 degrees, summer temperature exceeds 35 degrees, it is in a semi-dormant state, new branches and new leaves grow slowly, so summer should be properly shaded sun protection. Its cold resistance is weak, lower than 0 degrees easy to frostbite, so winter should pay attention to keep warm and cold, outdoor breeding should take good measures, it is recommended to transplant indoor, keep the temperature above 5 degrees, so as to safely winter.

3. Watering

Azalea like wet environment, the soil requirements moist but not wet, watering should not be too wet, otherwise easy to cause root rot. Spring and autumn temperature suitable for plant growth, can be 2-3 days of irrigation once permeable, hot summer, should be watered once a day, cold winter, should reduce the amount of watering and watering frequency. Water should not be alkaline, water temperature should not be too cold, cold water irrigation easy to affect soil temperature, interference plant growth. Azalea like the air humidity environment, in watering can also be sprayed on the leaves and growth environment, to maintain the air humidity around the plant.

precautions

1, pruning

Azaleas grow faster, it is easy to flourish, which will lead to internal branches and leaves do not see light, resulting in abnormal growth, so pruning is a daily job. Cutting off diseased branches, weak old branches and over-dense branches can increase ventilation and light transmittance, which is conducive to plant growth and can regulate growth and development, thus making it grow more vigorously. After the flower withers, it is also necessary to cut off the remaining flowers in time, so as to avoid nutrient consumption and improve sufficient nutrients for the next flowering.

2. Turning soil and changing pots

Soil after long-term watering will lead to hardening, soil hardening after poor permeability, is not conducive to plant growth, so no one or two months need to turn over the potted soil once. Rhododendron growth needs to consume nutrients, and the nutrients needed for growth come from the soil, so every one to two years to replace the potted soil, remove the old soil, replace the fertile new soil, so that it can grow healthily.

3. Diseases and pests

The main diseases of azalea are root rot, brown spot, black spot, leaf blight, iron deficiency chlorosis, etc. Before planting, the basin soil should be disinfected to keep the soil loose, moist and breathable, and the diseased plants should be treated in time after discovery. Azalea common pests are red spiders, military insects, aphids, short snails, etc., found in a timely manner after spraying with insecticides.

The above is the introduction of the cultivation methods and precautions of azaleas brought to you by the pro-agricultural network Xiaobian, hoping to help you.
