How do azaleas prune their branches and leaves? why don't azaleas blossom?

Rhododendron is a common species. The country once heard the bird, and Xuancheng also saw the rhododendron. Since ancient times, the rhododendron has often appeared in the writings of the literati, so it can be seen that the planting history of the rhododendron is very long. Today, the editor leads you to understand how to prune the branches and leaves of the rhododendron.

How to prune the branches and leaves of rhododendron

Rhododendron has a strong ability to germinate and regenerate. After the flower fades every 1-2 years, it is necessary to change a larger flowerpot and replace it with new culture soil.

After the cuckoo blossoms, its residual flowers often last for a long time, which consumes a lot of nutrients. In order not to let nutrients be consumed in vain, the residual flowers should be picked in time and sprayed with Zhuangtiling to provide nutrients to sprout new technologies. In addition, the shorter summer cuckoo has many transverse branches. every spring plum, many twigs sprout from the roots. In order to concentrate nutrients on the main branches and flowers, so that they can grow faster and have bigger gills, these twigs should also be cut off in time. If there are too many flowers, in addition to keeping each branch for a long time, the rest of the flower should also be removed. After pruning, the cut should be scrubbed with a healing anti-decay film to prevent bacterial infection.

You can decide which tree shape to trim according to your own preferences, such as umbrella shape, circle, semicircle, pagoda, square, etc., and then deliberately trim it.

Why don't azaleas bloom?

The main factors that azaleas do not blossom are lack of phosphorus, long-term overcast and long-term wet potted soil.

1. The most likely reason for rhododendron not to blossom is lack of phosphorus, because phosphorus is an important material basis of life and can promote the growth and development of roots, flowering, seeds and fruits. When phosphorus is deficient, azaleas cannot form flower buds, and withered azaleas without flower buds cannot blossom. When azaleas do not form flower buds at flowering stage, compound fertilizers with higher phosphorus and potassium can be buried at the edge of the pot to promote flower bud formation, so there is a better hope of flowering.

two。 Lack of sunshine, when photosynthesis cannot be carried out in dark places for a long time, unable to produce more nutrients to provide flower bud growth, azaleas will not blossom without flower buds. More sun can be moved out to enhance photosynthesis and produce more nutrients to provide growth and flowering.

3. Water control one month before flowering can also promote flower bud differentiation and make it easier to bloom.

The growing environment of rhododendron

Cuckoos are born in mountain sparse thickets or pine forests at an altitude of 500-1200 (- 2500) meters. They like acidic soil and do not grow well or even grow in calcareous soil. Therefore, pedologists often use rhododendron as an indicator crop of acidic soil.

Rhododendron likes cool, moist and ventilated semi-shady environment, and is afraid of both extreme heat and cold. The suitable temperature for growth is 12 ℃ to 25 ℃. When the summer temperature exceeds 35 ℃, the new shoots and leaves grow slowly and are in a semi-dormant state. Sunscreen should be used in summer and warm and cold in winter. Avoid hot sun exposure, suitable for growth under scattered light with low light intensity, too strong light, young leaves are easy to burn, new leaves and old leaves scorched edge, serious will lead to plant death. In winter, cuckoos cultivated in open field should take measures to prevent cold in order to ensure their safety through the winter. Among the ornamental rhododendrons, the cold resistance of rhododendron is the weakest, and the freezing injury is easy to occur when the temperature drops below 0 ℃.

How to water the cuckoo

The cuckoo requires that the soil is moist but not wet. In general, cuckoos planted in open fields can be watered every 2-3 days in spring and autumn, and at least once a day in hot summer. Daily watering, do not use alkaline water, watering should also pay attention to the water temperature should not be too cold, especially in hot summer, using supercooled water to penetrate, resulting in a sudden decrease in soil temperature, affecting root water absorption, interfering with plant physiological balance.

Water permeated once after planting and soil exchange, so that the root system was in full contact with the soil, so that the root could survive and grow. Pay attention to watering during the growing period, starting from March, gradually increase the amount of water, especially in summer, often keep the basin soil moist, but do not accumulate water, reduce watering after September, and re-irrigate the basin soil after entering the house in winter.

Rhododendron is a very good farmed plant, adaptable and able to grow in a very barren environment, which makes me think that we should also learn from rhododendron and be a person who can grow in all kinds of environments.
