With August here, many plants are moving through their beautiful summer bloom cycles and now have a number of spent blooms. In order to best stimulate regrowth for these plants, you should begin removing these dead flower heads. Removing these blooms, or “deadheading," also creates a clean look for your plant by removing the lackluster appearance of brown or dry flowers.
To do this, you will simply cut slightly below the plant head, entirely removing the spent portion of the plant’s bloom. However, when doing so, be careful not to remove any living foliage from the plant. By only removing the dead bloom, you are providing the plant with room to grow and blossom again, without being impeded. It also helps to conserve the plants energy and resources, allowing these to be focused on the thriving and growing portions.
This can be done with small hand shears, or even just your fingers in many cases where plants have thin stalks.
