Is it better to start dahlias from a clump of tubers or from an individual tuber? We get this question a lot. Having grown dahlias from both clumps and individual tubers, we find the results are usually very similar. Clumps offer some extra insurance because you get multiple eyes. This can be important for varieties that are less vigorous and is also helpful when growing conditions are not ideal.
Do Dahlias need storage space?
Dividing a clump into multiple tubers takes practice, patience and a steady hand. But for growers it's worthwhile, because each plant can yield many saleable tubers. And, if storage space is limited, individual tubers require much less storage space than clumps.
