Why Are the Flowers of Potted Roses Getting Smaller
The editor will explain why the flowers of potted roses get smaller, let's find out together.
If the cultivation conditions required by roses are not met, it will affect the normal growth of roses, causing the flowers to get smaller, or even not bloom at all. The main factors affecting the blooming of roses are as follows:
(1) The temperature is too high.
When the cultivation temperature exceeds 30℃, the growth of roses begins to be inhibited, the flower buds stop differentiating, and the already differentiated rose flower buds and formed flowers develop slowly, resulting in fewer flower buds, small flowers, dull colors, and shortened flowering periods. This situation often occurs in buildings. When potted roses are placed on sunny balconies in buildings during the summer, the temperature on the balcony can be several degrees higher than the ground temperature, not only causing the potting soil to dry out easily, but also the intense sunlight can burn the tender roots near the pot, leading to weakened growth of roses. In this case, not only do the flowers become瘦small, but sometimes it can even cause the rose to die.
Solutions: ① Do not place the rose pot directly on the concrete floor; instead, place a piece of wood under the pot and sprinkle water on the surrounding ground. ② Place a larger pot outside the rose pot to prevent the tender roots from getting burned. ③ Hang bamboo curtains to shade and cool down around noon. ④ Remove the small and pale flower buds to ensure good flowers after the heatwave.
(2) Insufficient light.
Roses prefer ample sunlight. If they are kept in a shaded environment for a long time, the branches become thin and long, the leaves are thin and pale, the flowers are few and small, the flower color is not right, and they may not bloom at all. Attention should be paid to increasing sunlight.
(3) Nutrient deficiency.
Roses bloom multiple times a year, so they need a continuous supply of nutrients to ensure good flowering. If roses are not fertilized enough, the flowers will get smaller. Therefore, it is important to fertilize the roses sufficiently to maintain larger flower diameters, fully display the characteristics of the rose varieties, and enhance the ornamental effect.
(4) No thinning of flower buds.
For many large-flowered rose varieties with side buds, it is important to thin out the side buds after they appear. This step should not be overlooked. Thinning out the side buds allows nutrients to be concentrated on the main bud (G-Y), so the rose flowers will not become smaller.
(5) Excessive growth of the plant.
If the branches and leaves of roses grow excessively, it can result in fewer and smaller flowers. To prevent excessive growth of roses, attention should be paid to timely pruning and reasonable watering to ensure robust growth of roses. The above is an introduction to why the flowers of potted roses get smaller.
