The importance of pruning

Pruning plays a crucial role in the cultivation of dahlias, offering the following benefits:

• Stimulates Flowering: By removing wilted flowers and dead leaves, the plant directs its energy towards producing new flower buds.

Pruning techniques

• Pruning wilted flowers: Remove wilted flowers as soon as they start to lose vitality. Cut the stems above the first set of healthy leaves.
• Pruning spent flowers: Cut off spent flowers and short stems to encourage the formation of new flowers.
• Branching pruning: To promote branching, cut the side shoots above the second set of leaves.

Propagation methods

Dahlias can be propagated by:

• Tuber division: During the dormant period, divide the tubers into pieces, making sure that each piece has at least one sprout.
• Cuttings: Cut cuttings from healthy stems, remove the lower leaves and plant them in moist soil until they take root.
