| Notes |
 Dahlias do so require the one-time task of pinching off the tops, once the tubers have sprouted and formed branches. Wait until three sets of branches appear, and then top the stem just above the highest set of branches. This pruning tactic encourages the plant to grow more branches, thus creating more blooms. |
