How to prolong the flowering period of rhododendron bonsai

People want to keep the good things for a long time, which is a kind of pursuit and desire for the good things. Just like the cuckoo, the rhododendron is beautiful in shape and rich in color, so it is very suitable to make bonsai for appreciation, but it is precisely because of its gorgeous blossom and high ornamental value that we all hope to get a longer viewing time. Therefore, to prolong the flowering period of rhododendron bonsai is a good work that we need to do. So, how to prolong the flowering period of rhododendron bonsai and make it take longer to watch flowers?

Different flowers and plants have different flowering periods, not only in different seasons, but also in different periods. This is not only determined by the characteristics of flowers and plants, but also affected by the growth environment. In order to keep the cuckoo bonsai open for a long time, we might as well try to improve its growth environment and change the means of conservation and management. In order to prolong the flowering period, we usually need to manage the light and temperature, water and fertilizer, pruning and other aspects of rhododendron bonsai.

I. growth environment

As cuckoos like to grow in a cool and humid environment, we usually need to create such a growth environment as much as possible, and the location is often very important. It is generally required that the location of cuckoo bonsai can not be exposed to the hot sun, nor can it lack the necessary light; it can not be in a state of high temperature for a long time, but also need to have a minimum temperature protection; it is not necessary to ensure smooth air circulation, and it is necessary to prevent strong winds from raging. At the same time, in order to do a good job of moisturizing, it is also necessary to spray more foliar water and surface water.

Second, basin soil requirements

Cuckoos prefer fertile and loose acid soil with good permeability, so when we mix soil, we can mainly use sandy loam with good permeability, and then mix some humus. Although cuckoos prefer to be moist, they are also afraid of stagnant water, especially in hot, humid and poorly ventilated environments. Therefore, in addition to scientific watering, it also requires the basin soil to have good permeability, once too much watering, so that excess water can be discharged in time. The addition of humus to the basin soil can add a lot of nutrients to the basin, which is very important to promote the growth and even flowering of rhododendron.

Third, scientific watering

Cuckoos like to be moist, but they are not resistant to waterlogging, especially in summer, where the temperature is relatively high and the weather is relatively hot, if coupled with poor ventilation, it is not only easy to breed diseases and insect pests, but also very easy to cause retting and rotting roots. And the cuckoo's root system is relatively small, and does not have a large number of robust roots, so the ability to absorb water is relatively poor, do not water too much. And rhododendron is a shallow root plant, generally shallow planting, even if watering can not be watered or flushed, otherwise it is easy to flush out the root system. Water is usually supplied by soaking the basin or spraying water. More importantly, if you are in hot summer weather, you should avoid replenishing water at the time of the day when the temperature is highest. At the same time, you should also pay attention to the water temperature, including watering in winter, so as not to let the water temperature contrast too much with the outside temperature.

IV. Rational fertilization

Cuckoos prefer fertile soil environment, but because its root system is too slender, obviously strong root system, so fertilization can not be too fierce, must control the concentration, mainly thin. At the same time, we should also avoid applying raw fertilizer, otherwise it is easy to burn out the roots of the plant, so that the roots can not absorb nutrients normally, affecting the growth of cuckoos. However, fertilization should also seize the opportunity, generally in the early spring and the end of winter to apply some organic fertilizer. However, because the rhododendron flowers are huge and the full bloom is in summer, it is not suitable to fertilize in the flowering stage, and flowering is a more nutrient-consuming thing. Therefore, we can top fertilize before and after flowering. Pre-anthesis topdressing is to promote flower bud differentiation and formation and reserve sufficient nutrients for flowering; post-anthesis topdressing is due to the consumption of a large amount of nutrients during anthesis and needs to restore and enhance tree potential through topdressing.

Pay attention to pruning

The pruning of rhododendron bonsai is generally carried out in spring and autumn, mainly to cut off old, weak and residual branches, overlapping branches, over-dense branches, cross branches and other branches that are not conducive to maintaining plant type but will consume nutrients in vain. At the same time, it is also necessary to remove residual flowers and cut short flower branches in time after flowering. Pruning scientifically can not only keep the beautiful plant type of rhododendron bonsai, but also save nutrients, improve ventilation and light transmission, promote photosynthesis, reduce the occurrence of diseases and insect pests, and stimulate plants to germinate new branches and leaves better. This can not only better promote the growth of rhododendron, so that it can always maintain a beautiful ornamental state, but also promote germination, especially the extraction of flower branches, so that the number of flowers is more, the quality is higher, and the appreciation of the whole bonsai is stronger.
