Chinese Rose Fails to Bloom Properly
There are four reasons why Chinese roses fail to bloom: excessive sunlight, which mainly occurs in late spring and early summer; low temperatures, which mainly occur in late autumn and early winter; too many flower buds; and insufficient nutrients. The first two situations can be resolved by artificial shading and insulation. If there are too many flower buds, smaller ones should be removed. If nutrients are lacking, fertilization should be applied promptly after flowering.
1. -- Excessive Sunlight --
In late spring and early summer, temperatures and the intensity of sunlight increase. Chinese roses can tolerate strong sunlight when the buds are small, but as the flowers gradually open and petals stretch, the outer petals may be sunburned and dehydrated under strong sunlight, preventing the inner petals from blooming.
2. -- Low Temperatures --
In late autumn and early winter, temperatures drop, especially at night, while Chinese roses require higher temperatures to bloom. Low temperatures can prevent blooming. In such cases, the roses can be moved to warmer indoor conditions or covered with plastic film to keep warm and insulated.
3. -- Too Many Flower Buds --
If not pruned in time, too many flower buds can also lead to the failure of Chinese roses to bloom. The buds compete for nutrients, and those on weaker branches, which develop later, may lack nutrients. In cultivation, it is necessary to thin the buds, leaving only the healthier ones and removing the smaller buds to concentrate nutrients.
4. -- Insufficient Nutrients --
Chinese roses can bloom continuously, and if not fertilized promptly, they may lack nutrients, especially in the same pot of soil over multiple years. The growth rate is fast in spring and summer, with continuous blooming and long flowering periods, so pruning and fertilization are essential after flowering to replenish the nutrients needed for blooming.
