Which pruning cut reduces density by removing interior growth?

• A. Heading cut
• B. Thinning cut
• C. Pinching cut
• D. Topping cut

Answer: (B)

Pruning to reduce density works by removing inner, crowded growth rather than simply shortening shoots. A thinning cut does exactly that: it takes out an entire branch at its point of origin or at the base, opening up the interior of the plant so light and air can move through the canopy. This directly lowers crowding and helps prevent disease and poor structure. Other cuts don’t achieve density reduction in the same way. A heading cut shortens a limb and encourages new shoots to form from the remaining stem, often increasing density rather than reducing it. Pinching removes just the tip to slow growth, which doesn’t address interior crowding. Topping cuts remove the top of the plant and typically trigger vigorous regrowth, potentially increasing density rather than thinning it.
