Protecting Tulip Bulbs from Squirrels in Ottawa

Squirrels digging up freshly planted tulip bulbs is a universal frustration for gardeners in Ottawa (Zone 5a). While repellents like blood meal, hen manure, or commercial sprays offer temporary relief, the only reliable, long-term solution is a physical barrier.

The Chicken Wire Method (Gold Standard)

1. After planting bulbs at the proper depth (6–8 inches), lay a sheet of 1/2-inch mesh chicken wire directly over the planting area.
2. Secure the edges with landscape staples, rocks, or soil so squirrels can't lift it.
3. Cover the wire with 1–2 inches of soil or mulch. The mesh is invisible but impenetrable.
4. In spring, tulip shoots push right through the openings. You can leave the wire in place permanently.

Why Other Methods Fall Short

• Repellents wash away with rain and need frequent reapplication.
• Blood meal/bonemeal can attract dogs, raccoons, or more squirrels.
• Cayenne pepper is inhumane and washes off.
• Bulb cages work but are labor-intensive for large plantings.

Pro Tip

Plant tulips deeper (8 inches) and interplant with daffodils or alliums—squirrels dislike their taste and smell. But the wire barrier remains your best insurance.

Invest an hour now with chicken wire, and you'll enjoy a squirrel-free tulip display for years.
