If you live in Seattle or its surrounding neighborhoods—especially in more wooded areas like Mercer Island, West Seattle, or parts of North Seattle—you may have noticed deer making themselves at home in your yard. While deer sightings can feel like a charming part of living close to nature, they often come at the expense of your carefully planned landscape.
At Seattle Sustainable Landscapes (SSL), we regularly work with clients whose gardens have become buffet lines for browsing deer. The good news? With smart plant choices and thoughtful design strategies, you can have a beautiful landscape that holds up—even in deer-prone areas.
Why Is Deer Browsing a Problem?
Deer can cause significant damage to residential landscapes by:
- Stripping bark from young trees
- Eating tender shoots, flowers, and foliage
- Trampling plants and compacting soil
- Damaging irrigation systems and mulch with their hooves
This is particularly common in areas like Mercer Island, where deer populations are higher due to greenbelt corridors and limited natural predators. However, deer damage is increasingly reported throughout Seattle, especially near forested parks, ravines, and less densely developed neighborhoods.
Deer-Resistant Design Strategies
1. Choose Deer-Resistant Plants
No plant is completely deer-proof, but some are far less appealing to them. Deer typically avoid plants that are:
- Aromatic (e.g., lavender, rosemary, sage)
- Leathery or tough (e.g., hellebore)
- Fuzzy or spiny (e.g., lamb’s ear, barberry)
- Toxic or irritating (e.g., foxglove, daffodils)
Great Deer-Resistant Plants for Seattle Gardens:
- Sword fern (Polystichum munitum)
- Oregon grape (Mahonia aquifolium)
- Salal (Gaultheria shallon) – they will eat the berries 😀
- Catmint (Nepeta spp.)
- Coral bells (Heuchera spp.)
- Western bleeding heart (Dicentra formosa)
These native and adapted species not only deter deer, but also support pollinators and require minimal maintenance.
2. Design with Layers and Zones
A layered planting approach can discourage deer access and guide them away from prized plants:
- Place highly desirable plants near the house or inside fenced zones
- Use tougher, less palatable plants on the perimeter
- Plant densely—deer prefer open areas with easy browsing access
3. Create Physical Barriers Without Compromising Style
While 8-foot fences are the most effective way to exclude deer, they’re not always feasible or aesthetically ideal. Alternatives include:
- Terracing on slopes, which creates physical and visual breaks
- Raised beds to elevate plants above browsing level
- Decorative fencing or screens that blend with the landscape
We design these elements to look intentional—not like fortifications.
4. Supplement with Natural Deterrents
When pressure is high, even resistant plants may get sampled. In those cases, we may recommend:
- Motion-activated sprinklers
- Scent-based repellents (e.g., garlic, predator urine, or commercial formulas)
- Reflective tape or visual distractions (best as temporary aids)
