Recently, some flower enthusiasts have asked why the flower buds of chrysanthemums (ball chrysanthemums) wither before they bloom? They don't know what to do. In fact, it is quite common for ball chrysanthemum buds to wither without blooming. Summarizing the reasons, they are commonly seen in the following points.
1. -- Lack of Fertilizer --
In our impression, chrysanthemums are very tolerant of poor soil. Chrysanthemums planted in the ground often do not require management and can bloom in autumn. Therefore, many flower enthusiasts manage potted ball chrysanthemums or multi-branched chrysanthemums in a rather rough manner and rarely fertilize.
But ball chrysanthemums and multi-branched chrysanthemums produce a large number of flowers, can grow many flower buds at once, and are potted. The root growth space is limited, and the available nutrients are limited. If little fertilizer is applied during routine maintenance, it may cause the flower buds to develop slowly or even wither due to insufficient nutrients in the potting soil.
If little fertilizer is applied before the flower buds grow, it is essential to apply phosphorus and potassium fertilizers promptly after the flower buds appear. It is recommended to apply monopotassium phosphate once a week, both for root irrigation and foliar spray. If it is not feasible to consistently use water-soluble fertilizers, it is recommended to apply slow-release fertilizers around the pot to provide a continuous nutrient supply and avoid a large number of withered flower buds due to a lack of fertilizer.
2. -- Drought --
Drought is also a common reason for the withering of ball chrysanthemum flower buds, especially when the crown of the ball chrysanthemum is large and the pot is small, the potting soil dries quickly. If watering is not timely or not thorough, drought may occur.
In hot weather, if the pot is small and prone to drought, you can place a water tray under the pot and keep water in the tray every day. This way, the potting soil will absorb the moisture from the tray during the day when it is dry, maintaining moisture and preventing drought. Of course, replacing the pot with a suitable size is the best option.
3. -- Waterlogging in the Pot --
Drought can cause the withering of ball chrysanthemum flower buds, and so can waterlogging, especially during the transition from summer to autumn. Changes in temperature and sunlight slow down the drying of potting soil. If watering is still done at the summer frequency, it can easily cause root rot in ball chrysanthemums due to waterlogging. When the roots of ball chrysanthemums are damaged, they will first choose to abandon the flower buds to survive. Therefore, it is important to maintain the principle of "watering when dry and keeping the soil slightly moist," adjusting the watering frequency according to the season.
4. -- Insufficient Light --
The development of ball chrysanthemum flower buds requires sufficient light. If there is insufficient light for a long time, it can also cause abnormal development of the flower buds and lead to withering. Chrysanthemums are not afraid of sun exposure and should maintain sufficient light, with at least 4 hours of direct sunlight per day being ideal. Sufficient light prevents ball chrysanthemums from becoming leggy and is beneficial for flower bud development.
5. -- Sudden Environmental Changes --
In addition to the above four points, sudden environmental changes may also cause the withering of ball chrysanthemum flower buds. For example, if a ball chrysanthemum that was previously maintained in a shaded greenhouse is suddenly moved to an environment with full sunlight, this transition may cause the flower buds to wither due to insufficient water, as the plant may not be able to adapt to the rapid environmental change. It's like when we stay indoors for a long time and suddenly go out into the sun; we not only find it hard to open our eyes but also feel our skin burning, and plants are the same.
Therefore, new seedlings must be acclimatized first, gradually increasing the light exposure to give them a period of adaptation. Moreover, repotting during the flowering stage may also cause the withering of ball chrysanthemum flower buds because repotting inevitably damages the plant's roots. If proper management is not implemented after repotting, withered flower buds may appear. Therefore, it is not recommended to repot during the flowering stage. If repotting is necessary, it should be done with the original soil and watering should be based on the moisture level of the original soil ball to avoid drought or waterlogging.
That's the detailed introduction to the reasons for the withering of chrysanthemum buds on the west side. Have you understood it?
