Reviving a Non-Blooming Climbing 'Peace' Rose in Kentucky

A 5–6 year old Climbing 'Peace' that hasn't bloomed in 3–4 years needs three things: sun, food, and correct pruning.

1. Sun Is Non-Negotiable

Roses need full, all-day sun. Half-day = few blooms. Shade = none. If a tree shades it, move it or limb up the tree.

2. Feed for Flowers

Roses need high nitrogen and high phosphorus. Use a dedicated rose fertilizer (slow-release pellets). Nitrogen builds leaves; phosphorus builds blooms. You need both.

3. Pruning Climbing Sports

Climbing 'Peace' is a sport of a bush rose. Heavy pruning can revert it to bush form. University of Nebraska warns: don't prune heavily in first 2–3 years. Danny Weaver (GA rosarian) says: prune selectively every year to prevent tangles. Follow his step-by-step guide. Do it in late winter.

Black Spot Management

Hybrid teas are prone. No cure exists—only prevention. Spray healthy leaves weekly from early spring: 3 tsp baking soda + 1 tbsp dish soap/gallon. Remove every fallen leaf now. Cornmeal at the base (early spring, monthly) shows promise. Avoid Daconil (chlorothalonil)—a known carcinogen.

Get a good sprayer now. Start the program in March.
