How many times a year do dahlias bloom?

1. Multiple opening

Dahlia is a bulbous flower of the Asteraceae family. It has a particularly long flowering period, and can bloom many times as long as environmental conditions allow and the nutrients in the body are sufficient. Generally speaking, in most environments in our country, it can bloom normally outdoors in May until the first frost arrives in November, when it stops blooming.

2. Ideal flowering temperature

During this process, if the temperature is too high in summer, the dahlia will stagnate for a short period of time. Generally speaking, the ideal flowering temperature is around 20 degrees. Each time the flowers bloom and fade, the withered flowers must be trimmed off. The leaf buds at the bottom of the flower stalk can sprout new branches again. As long as there are sufficient nutrients, new flower buds can be produced. Therefore, it is in a state of continuous flowering during this period of time, and the flowering period is generally long.
