How to make rhododendron bonsai blossom

The rhododendron bonsai blossoms brilliantly and has high ornamental value, but we need to create a comfortable growth environment for it, and the daily maintenance and management must be done well. Only in this way can the cuckoo have a variety of conditions for flowering. So, how to manage to make the rhododendron bonsai blossom? Today, the editor will come to discuss with you the maintenance and management methods to make cuckoo bonsai blossom more.

I. growth environment

First of all, we need to prepare a high-quality soil environment for rhododendron bonsai, because cuckoos like acid soil that is fertile and loose, rich in humus and good drainage, so we need to allocate soil according to this standard. According to the characteristics that cuckoos like cool and humid climate, the location we choose needs to keep semi-shade ventilation, because plants are easy to be infected with diseases and insect pests in hot, humid and airtight environment, and the location is also convenient for water management.

Second, scientific watering

Only when the cuckoo bonsai keeps growing well can it have the conditions to bloom, so in addition to scientific light and suitable temperature, watering should also be done well. However, considering that rhododendron is a shallow root plant, it is generally planted shallowly, so it can not loosen the soil, otherwise it is easy to damage the root system. Therefore, the selected water source has certain requirements on water quality, especially to avoid the use of alkaline water, soft water is better. In this way, the consolidation of basin soil can be avoided or delayed. And replenishing water should be carried out by soaking in the basin, which is more sufficient and can avoid flushing out the roots of cuckoos because of direct watering. At the same time, it is also necessary to combine spraying foliar water and surface water to moisturize and cool down, especially during the summer flowering period.

III. Rational fertilization

For most flowers and plants, it is suitable for topdressing because of the high temperature and hot weather in summer. The same is true for cuckoo bonsai, but because cuckoos bloom in summer, they often need a lot of nutrients to support their flowering, so they need to prepare enough nutrients in advance. But even so, the topdressing of rhododendron should be carried out before flowering, mainly to promote flower bud differentiation. Generally in the flower bud differentiation stage and bud stage, you can maintain every 10 days or so to apply thin phosphate fertilizer to promote flowers. Phosphate fertilizer can be applied 1-2 times before flowering, and compound fertilizer can be applied 1-2 times after flowering to restore tree potential.

4. Proper pruning

The pruning of rhododendron bonsai can be carried out before and after flowering, and pre-flowering pruning is to save some nutrients, promote the growth of flower branches, mainly cut off old, weak, sick and residual branches and branches that affect the beauty of plant type, so as to improve the permeability of bonsai, improve ventilation and increase daylighting, so as to better promote plant growth; post-anthesis pruning is mainly to reduce nutrient consumption, so as to quickly restore tree posture and maintain beautiful plant type. In order to promote flowering and extract more flower branches, we especially need to do a good job of pruning in spring.

V. Disease and pest control

Diseases and insect pests are an important factor affecting the flowering of rhododendron bonsai, so we usually have to do a good job in prevention and control. Once the rhododendron bonsai is attacked by diseases and insect pests, it will inevitably affect the tree potential, inhibit growth, and thus affect the flowering effect, so it is necessary to spray it in time to ensure that the plant can maintain a normal growth state and will not affect the flowering time and effect. The hot, humid and airtight environment during flowering is often easy to breed diseases and insect pests, so we must do a good job in improving the growing environment of rhododendron bonsai.
