Deadheading, or the removal of faded or spent flowers, serves a dual purpose: it prevents plants from putting energy into seed production and encourages new growth. To effectively deadhead, inspect your flowering plants weekly. Use clean, sharp scissors or pruning shears to snip off wilted blooms just above the first set of healthy leaves. For plants like roses, cut back to an outward-facing bud to promote open growth. Remember that some species such as marigolds benefit from simply pinching off old flowers with your fingers.
