Shaded Roses with Aphids and Brown Leaves: Move, Prune, Feed, and Garlic

Sylvia: 4 roses along fence in shade. Only 1 blooms. Others brown leaves, chronic aphids. Tried every spray. Never pruned.

Root Cause: Shade

Roses need 6+ hrs sun to bloom and resist pests. Shade = weak growth, disease, aphid magnets.

Two Paths

Option 1 (Best): Move to sun. Prune to 3 ft. Feed 6-wk granular + weekly liquid. Plant garlic cloves at base (aphid deterrent). Hose off current aphids.

Option 2 (If stuck): Prune/feed same. Accept fewer/smaller blooms. Garlic + hose for aphids.

Pruning = Non-Negotiable

Never pruned = old wood harbors disease/aphids. Hard prune now (late winter ideal, but do it) renews plant.
