A single dahlia bulb, also known as a tuber, can produce numerous flowers throughout its growing season. The exact number can vary greatly depending on the care provided, the variety of the dahlia, and the growing conditions. However, it's not uncommon for one dahlia tuber to yield between 20 to 40 blooms during the summer and early autumn months. Some well-tended dahlias can even produce more. It's important to note that to maximize flower production, regular deadheading or removal of spent blooms is recommended. This encourages the plant to continue producing new flowers instead of diverting energy to seed production.
