Five reasons why roses are getting smaller
The cultivation of Chinese rose, if it does not have the required growth conditions, will affect its normal growth, so the flowers will become smaller and smaller, or even do not bloom. The main reasons for affecting flowering are as follows:
1. The temperature is too high
When the temperature exceeds 30 ℃, the growth of rose is inhibited, the flower bud no longer differentiates, the differentiated flower bud and the formed flower bud develop slowly, the flower bud is few, the flowering is small, the flower color is dim, and the flowering period is shortened. This kind of situation mostly occurs in the building, generally put the flowerpot on the south-facing cement balcony to cultivate, the balcony temperature is high at noon in summer, the basin soil is easy to dry, and the hot sun exposure, the basin wall temperature rises can burn tender root, cause the growth to weaken, not only the flower is thin and small, even cause the plant death. In order to prevent this phenomenon, some measures should be taken.
Rose: there are four ways for rose to blossom more.
Do not put the flowerpot directly on the cement floor, put a wooden board under the pot and sprinkle water on the surrounding ground
Put a large basin on the outside of the basin to prevent the tender roots from burning
Hang bamboo curtains around noon to shade and cool down.
Remove the smaller, lighter buds and keep the nutrients so that they can blossom after the heat.
2. Lack of light
Rose flowers like to have plenty of sunshine, if they are cultivated in a shady environment for a long time, the branches are slender, the leaves are thin and light, the flowers are few and small, the flowers are dim, or even do not blossom, we should pay attention to increase the light, the conditions allow open-air cultivation is the most conducive to the growth of rose, so as to ensure as much light as possible.

3. Lack of nutrition
Rose blossoms many times a year and needs continuous nutrition in order to blossom well. If the fertilizer is insufficient, the flowers will bloom smaller and smaller, so it is necessary to apply enough fertilizer in order to maintain the characteristics of the variety and enhance the ornamental effect. Cut off the residual flowers after each flower, and then apply fertilizer in time.
4. There is no Shulei.
For many rose varieties with large flowers and lateral buds, if there are too many lateral buds, they will disperse nutrients, so that the buds are not nutritious enough and the flowers become smaller. After budding, lateral buds should be removed in time, nutrients can be concentrated to supply the main buds, so that the rose flowers will not become smaller.
5. Overgrowth of plants
If the branches and leaves grow in vain, it will also result in fewer flowers and smaller flowers. Attention should be paid to timely pruning and proper watering to make rose plants grow healthily and cut off overgrown branches and residual flowers.
