Why do rose flowers bloom smaller and smaller?
Roses are a common green plant in our daily life, able to beautify the environment and purify the air. During the process of growing roses, some friends may notice that their roses bloom smaller and smaller. What causes this? Let's take a look together with the editor.
1. Temperature too high
When the temperature exceeds 30°C, the growth of roses will be inhibited, flower buds will no longer differentiate, and flowers that have already sprouted and formed will develop slowly, with fewer buds, poor flowering, dull flower color, and a shortened flowering period. Therefore, attention should be paid to cooling down during hot seasons. During the day, 18-25°C should be maintained, and at night 10-15°C. These are the most suitable conditions for rose flower growth; above 30°C will lead to poor growth.
2. Insufficient light
Roses prefer a sunny, well-lit environment. If they are cultivated in a shaded environment for a long time, the branches will become slender, the leaf color will be dull, the flowers will be few and small, the flower color will be off, and they may even fail to bloom. Therefore, attention should be paid to increasing light. Generally speaking, the daily light duration should not be less than 6 hours, so as to facilitate photosynthesis and accumulate nutrients. In addition, watering should be well controlled: it is best to water thoroughly after the soil has dried out. In spring, summer and autumn, water before 10 o'clock, and maintain relative humidity at 75-80%.
3. Lack of nutrients
Roses bloom multiple times each year, so nutrients must be continuously replenished to keep them blooming well. If fertilization is insufficient, the flowers will bloom smaller and smaller. Therefore, attention should be paid to fertilizing so that the flowers can maintain a larger flower diameter and thus improve their ornamental value. In addition, repotting once a year should be insisted upon. If not repotted for a year, there will certainly not be many flowers that year; if not repotted for several years, the leaves will definitely be sparse and the flowers small. Sufficient decomposed organic fertilizer should be added to the potting soil, and a small amount of fertilizer should also be added when watering normally. Generally, before budding, water with fertilizer once every 7 days, and after flowering, once every 10 days.
4. Spindly overgrowth of the plant
When the temperature is suitable, fertilizer and water are sufficient, and the plant has not been pruned, the rose branches and leaves are very prone to spindly overgrowth. This will also cause roses to bloom less, and the flowers to be small. To avoid spindly overgrowth of the plant, attention should be paid to timely pruning and reasonable watering.
