Why do roses only grow branches but not bloom?

reason

1. Barrenness

The soil used for cultivation is poor or the potting soil has not been replaced for a long time, the fertility is weak, and the nutrition is deficient, especially the phosphorus fertilizer content is too low, which inhibits the normal differentiation of flower buds and thus affects normal flowering.

2. Poor ventilation

The cultivation environment is located in a shaded place with poor ventilation and insufficient light, which inhibits the germination of flower buds.

3. Improper pruning

The pruning work was not done properly, the branches were too dense, the nutrients were dispersed, and the flower buds lacked the nutrients they needed for growth.

4. Temperature is too high

The temperature in midsummer is high, causing the soil temperature to rise above 30°C, which inhibits the normal physiological functions of the root system. High temperature can also easily cause water shortage, making the soil layer at the root system dry and hot, which can easily lead to wilting of branches and leaves and scorching of leaf edges, which is not conducive to autumn flowering. Therefore, watering must be sufficient in summer, and the potting soil can be properly covered with small pieces of corn cobs and short plant stems. When watering, you should try to remove the covering material to allow water to directly contact the potting soil to facilitate the reduction of soil temperature and control water evaporation.

5. Temperature is too low

The temperature in early spring in the north is difficult to predict, and frost damage often occurs. This period is the sprouting of rose axillary buds, differentiation of flower buds and growth of new shoots. Therefore, it is necessary to avoid frost damage caused by late frost and cold currents, otherwise the growth of flower buds will be hindered and it will be difficult to form buds and bloom. The new shoots will wither after being frozen, which will reduce the flowering rate of the first flowering. In summary, timely and effective protective measures should be taken against frost damage.

6. Pests and diseases

The final reason may be that the plant was infected by disease and failed to receive timely and effective prevention and treatment, which led to its death and naturally it would not bloom.
