When Is the Dahlia Blooming Season? A Detailed Guide to Its Blooming Time
Dahlias are mainly famous for their long blooming season, large flower stems, and abundant blooms. They are native to Mexico, where people regard them as a symbol of generosity and magnificence, and therefore honor them as the national flower. So when is the dahlia blooming season?
1. Dahlia Blooming Season
The dahlia blooming season falls into two periods: May to June and September to November. The flowers that open in late September are the largest, most vivid, and most abundant, but they are not frost-tolerant, and the stems and leaves wither immediately after frost. If you need them to bloom in winter and early spring, you must control sunlight and temperature. Studies show that short-day conditions and low temperatures are the main factors preventing dahlia flower bud differentiation. By controlling winter sunlight to about 14h and keeping the night temperature above 10°C, you can produce cut flowers with large blooms and vivid colors.
2. How Can You Make It Bloom as Soon as Possible?
1. Plenty of light
Whether you grow it in a pot or outdoors, you must give it enough light. This is especially true for potted plants. During normal care, do not always keep it indoors; move it frequently to a sunny spot to sun it, which is more conducive to early blooming and can also extend the blooming time. Although it loves sunlight, in summer you should provide some shade, because the light is too intense at that time and can easily make it go dormant.
2. Suitable temperature
It is usually afraid of cold. In other words, it prefers a warmer place. If during normal care you can keep the temperature between 15°C and 25°C, it will grow better and bloom earlier, because the temperature within this range is most suitable for its growth. But it must never exceed 32°C, because once it does, it will stop growing, which also affects blooming.
After learning about its blooming season, you should know that one period falls in summer. Summer is hot and rainy. If you grow it outdoors, provide shade and rain protection in time, otherwise it can easily develop root rot.
