Starting a Deer-Resistant Garden: Strategy Beyond Plant Lists

How to start a deer-resistant garden — the strategic approach beyond plant lists, including fencing, repellent rotation, and planting design for genuinely moderate to high deer pressure.

Understanding deer behavior, not just plant lists

Deer are browsers, not grazers — they selectively prefer plants with soft, lush, high-protein foliage. Per Rutgers Cooperative Extension, which maintains one of the most comprehensive deer resistance ratings systems, deer "tend to avoid plants that are aromatic, have leathery or hairy leaves, or produce milky sap." They are highly adaptable — populations that initially avoided catmint or lavender in an area will browse them readily once deer density increases enough that preferred plants become scarce.

Key behavioral context: deer browse most heavily in winter (when food is scarce), in early spring (when does are pregnant or lactating and need protein), and during summer drought (when their preferred plants go dormant or dry out). A plant that was untouched for five years may suddenly be browsed when any of these conditions changes.
