Rejuvenating an Old Climbing Rose with Sparse Foliage: Hard Pruning Works

A 12-year-old climbing rose in a sunny corner had sparse foliage for 3 years despite monthly granular and weekly liquid fertilizer. It still flowered but looked bare.

Age-Related Decline

Old climbers lose vigor to produce dense foliage. Hard pruning (cutting back by 1/3) stimulates fresh, leafy basal growth. It delays flowering by ~2 weeks but dramatically improves appearance.

Drastic Option

After 10+ years, some gardeners cut bred climbers (not sport climbers) to the base. They regrow vigorously. Try 1/3 first; it's safer and effective.
