Spur-pruned pruning involves which of the following?

Spur-pruned pruning involves which of the following?

• A. A green shoot will harden to become a woody cane after a season—along the cane are a number of buds, which will each produce a shoot during spring budbreak. The spur is a cane cut back to two buds. If a vine is spur-pruned, the upper cane growing from a spur will be removed during winter pruning, and the lower cane growing from the same spur will be cut back to two buds, creating a new spur.
• B. The spur is a permanent cane extended from trunk and never pruned.
• C. Spur pruning uses a single main two-year-old cane only.
• D. Spur pruning refers to removing all fruiting canes every year.

Answer: (A)

Spur pruning relies on creating short, two-bud spurs on a permanent structure and renewing them each year. A spur is a cane cut back to two buds, and in winter you prune in a way that removes the newer upper growth from that spur while leaving the lower cane cut back to two buds to form the next spur. This keeps a predictable, limited fruiting unit and promotes regular fruiting on a manageable cane. The other descriptions describe different pruning approaches. Keeping a permanent cane that is never pruned aligns with cane pruning, not spur pruning. Relying on a single main two-year-old cane isn’t how spur pruning is typically managed, which centers on two-bud spurs rather than a long-aged single cane. Completely removing all fruiting canes annually would erase the perennial fruiting structure that spur-pruned systems depend on.
