When do chrysanthemums bloom?
The following is an introduction to the related experience of when chrysanthemums bloom for flower planting enthusiasts. Next, the editor will introduce to everyone.
The blooming period of chrysanthemums is in autumn, specifically between September and November. There are many varieties of chrysanthemums cultivated now, with a variety of colors such as yellow, red, orange, purple, pink, and dark red. The petals also come in various types, including single-petaled, flat-petaled, spoon-petaled, and they have very high ornamental value. However, to make them bloom better, it is necessary to pay attention to the management during the blooming period and provide a suitable environment.
One, When do chrysanthemums bloom?
Most chrysanthemums bloom in September, but due to environmental and variety reasons, the blooming time may vary. Summer chrysanthemums bloom in May and June, autumn chrysanthemums bloom in September, late chrysanthemums bloom from October to November, cold chrysanthemums bloom from December to January, wild chrysanthemums bloom from June to November, sweet chrysanthemums bloom in May, and small red chrysanthemums bloom from July to October. Of course, the blooming period can also change with the adjustment of artificial lighting and other factors.
Two, What is the blooming month of chrysanthemums?
The blooming period of chrysanthemums is generally from September to November. There are many types of chrysanthemums, and they are widely planted in various regions, with no fixed blooming time, but most of them bloom in autumn. However, there are also chrysanthemums that bloom in summer and winter. Under normal natural conditions, they can be divided into summer chrysanthemums (blooming from May to September), autumn chrysanthemums (blooming from October to November), and cold chrysanthemums (blooming from December to January), usually lasting for about 20-35 days. But through the cultivation of horticulturists and changing daylight conditions, there are also May chrysanthemums that bloom in May, July chrysanthemums that bloom in July, and August chrysanthemums that bloom in August.
Three, What are the reasons why chrysanthemums do not form buds or bloom?
1 -- Internal factors --
Chrysanthemums belong to short-day plants. Under the condition of ensuring less than 12 hours of sunlight per day, chrysanthemums can differentiate flower buds early in the vegetative growth stage. At the same time, in addition to short-day conditions, a lower temperature and maintaining a day and night temperature difference of about 10 degrees Celsius are required for the environmental conditions so that the apical bud of chrysanthemums can be transformed into a flower bud and then form buds and bloom. Therefore, the reason why chrysanthemums do not form buds or bloom may be due to the lack of the above conditions.
2 -- External factors --
Improper maintenance in daily life can also affect the differentiation of flower buds in chrysanthemums, which is the external factor for chrysanthemums not blooming. For example, the following situations will affect the differentiation of flower buds: excessive watering during the seedling stage, untimely pruning, not pinching and pruning at the appropriate time, improper fertilization, excessive application of nitrogen fertilizer, and lack of phosphorus and potassium fertilizers, which can cause the stems and leaves to grow excessively and make the buds on the plant all turn into leaf buds.
Four, What to do if chrysanthemums do not form buds or bloom
1 -- Light
Usually, after chrysanthemums have grown about ten leaves, maintaining the day length within the range of 14 to 15 hours, it is necessary to shorten the day length and provide as much short-day growth conditions for chrysanthemums as possible to promote bud differentiation.
2 -- Watering
Remember the characteristics of chrysanthemums, which require a lot of water, are afraid of waterlogging, and are drought-resistant. Watering should be sufficient in summer, generally once in the morning and once in the evening. After blooming, the amount of watering should be gradually reduced, and similarly, watering should also be appropriately reduced in winter. Pay attention to prevent waterlogging in the pot and do a good job of ventilation.
3 -- Fertilization
When repotting, it is necessary to apply sufficient base fertilizer. For convenience, the base fertilizer can be chosen from leftover food at home. After entering autumn, apply a fully decomposed thin liquid fertilizer once every week or so. During the bud formation period, it is necessary to apply 2 to 3 times of 0.2% phosphorus acid hydrogen potassium or 0.5%-1% calcium superphosphate solution.
4 -- Pinching
Pinching can promote branching in chrysanthemums. It is generally done on sunny days, after the roots of the chrysanthemum seedlings have formed, about 3 weeks after the cuttings, the first pinching is done by removing the unexpanded top. The second pinching is done when the top new buds sprout, and when 4 or 5 leaves have grown, the poorly growing leaves are removed, and then pinching is done once a month, stopping after the end of August. Keep the healthy sprouting branches and cut off the extra ones to prevent nutrient waste. Remember to apply a decomposed fertilizer after each pinching to promote the growth of lateral buds.
Chrysanthemums enjoy sufficient sunlight and are very drought-resistant. They will grow very well in a warm and humid environment. In addition, since chrysanthemums are short-day plants, the daylight hours during cultivation should be less than 12 hours, and the blooming period can be controlled by changing the daylight hours and pinching.
The above sharing of when chrysanthemums bloom, the blooming month of chrysanthemums, and the reasons why chrysanthemums do not form buds or bloom, hope it is helpful to green plant enthusiasts!
