Variety History

If this rosemary is a grocery-store start, it may be a tender variety (most common rosemary sold is not reliably hardy below zone 8). Hardy varieties like Arp or Hill Hardy overwinter reliably.

Regional Context

Rosemary is marginally hardy on Bainbridge depending on variety. Plan to mulch heavily in November. Prune only into green wood -- cutting into bare wood can kill branches.

Growing Technique

Spring cleanup: prune to shape, but only into green wood (bare wood does not regrow). Top-dress with compost. Harvest year-round. If the plant is a tender variety, treat it as needing winter protection.

Watch For

Pruning into bare wood kills branches. Rosemary does not regenerate from old wood -- always leave green growth on any branch you cut.
