What is the reason that Rieger Begonia only grows leaves but does not blossom

Rieger crabapple not only has large green leaves, but also its flowers are colorful and ornamental, and the flowering period is very long, so many potted friends like to plant it as a family pot for appreciation. However, Rieger crabapple is not easy to raise, a little carelessly may have poor growth. Potted Rieger Begonia is more likely to grow stems and leaves without flowering, so what is the reason why Rieger Begonia only grows leaves and does not blossom?

For ornamental flowers and plants, if there are only leaves but no flowering, it is bound to increase the ornamental value of potted plants, and it is obvious that this is a phenomenon of poor growth. In order to help those who encounter such problems to find out the cause, today the editor will discuss with you the reason why Rieger Begonia only grows leaves but does not blossom and how to deal with it.

1. Lack of light

As the stems and leaves of Rieger Begonia grow luxuriantly, but they do not conceive buds and do not blossom, so potting soil and watering should not be a big problem. After all, the plant has the phenomenon of exuberant leaf growth. So, we need to investigate the next factor that may cause non-flowering. The lack of light is easy to cause the overgrowth of the plant, so the first reason may be that the environment is too shady and the plant does not blossom because of the lack of light. To this end, we need to increase the light for it in time.

Second, insufficient pruning

Rieger Begonia in a suitable growth environment, the original tends to grow more exuberant. But if the leaves are too exuberant, they will get more nutrients, so that the plant will only grow stems and leaves, and there are not enough nutrients to bud and bloom. For this reason, we need to coring or topping the plant in time, so that the plant loses its apical growth advantage, which can promote the plant to germinate flower branches, and then get more nutrients to promote bud pregnancy and flowering.

III. Nutritional imbalance

Rieger crabapple likes fertilizer, at the same time, its flowers and leaves are large and numerous, and the consumption of nutrients is relatively large. In addition to the timely application of nitrogen, phosphorus and potassium compound fertilizer during the growing period, it is also necessary to supplement phosphorus and potassium fertilizer that can promote flowering at the bud stage of flowering, and it is usually more appropriate to apply potassium dihydrogen phosphate once a week. If there is not enough phosphorus and potassium fertilizer and only enough nitrogen fertilizer, it will inevitably lead to the plant does not have enough energy to achieve budding and flowering, but only long leaves. Therefore, the timely supplement of adequate nutrients during the bud period is very important for its flowering.

Of course, there are many factors that cause Rieger Begonia not to blossom, but if it is to grow branches and leaves without flowering, it is usually caused by the above three factors. If there are too many buds to bloom, we must properly remove some buds in order to successfully open the buds and make the flowers bigger and more beautiful. Because too many buds will disperse nutrients, thus reducing the quality of flowering, and may even cause the phenomenon that the bud can not be opened smoothly.
