What pruning technique is used to selectively cut terminal ends of twigs or branches back to any auxiliary bud or node to produce a denser plant?

• A. Thinning.
• B. Completely removing branches back to the trunk.
• C. Opening back pruning.
• D. Heading back.

Answer: (D)

Heading back is the pruning approach used when you want a plant to become denser. By shortening the terminal ends of twigs or branches to an auxiliary bud or node, you release growth from those buds just below the cut. This stimulates multiple new shoots to emerge from that point, resulting in a bushier, more crowded canopy. It’s a common technique for shrubs and hedges when the goal is to increase density and refine shape.

Think of it this way: you’re not removing the interior structure or a lot of wood; you’re stimulating new growth right where you cut, which drives a denser result. Other methods—removing branches at their base to thin out interior space, cutting all the way back to the trunk, or opening up the canopy to reduce density—do the opposite of what you want when the aim is more fullness.
