What causes rose flowers to bloom smaller and smaller?
Roses are a common type of greenery in our lives, able to beautify the environment and purify the air. However, 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.
1. Temperature too high
When the temperature exceeds 30°C, the growth of roses is inhibited, flower buds stop differentiating, and flowers that have already sprouted and formed develop slowly, with few buds, poor blooms, dull flower color, and a shortened flowering period. Therefore, attention should be paid to cooling 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, growth will be poor.
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 thin and elongated, the leaf color will be dull, flowers will be few and small, the flower color will be off, or they may even fail to bloom. Therefore, attention should be paid to increasing light exposure. Generally speaking, daily light duration should not be less than 6 hours to facilitate photosynthesis and the accumulation of nutrients. In addition, watering should be well controlled: water thoroughly when the soil is dry. In spring, summer, and autumn, water before 10 o'clock, and maintain relative humidity at 75-80% for best results.
3. Lack of nutrients
Roses bloom multiple times each year, so nutrients must be continuously replenished to keep them blooming well. If fertilizing 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, thereby improving their ornamental value. In addition, repot once every year. If the pot is not changed for a year, there will definitely not be many flowers that year. If the pot is not changed 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. Excessive vegetative growth
When the temperature is suitable, fertilizer and water are sufficient, and the plant has not been pruned, the branches and leaves of roses are very prone to excessive vegetative growth. This will also cause roses to bloom less, and the flowers to suffer. To avoid excessive vegetative growth, attention should be paid to timely pruning and reasonable watering.
