Electric Fencing for Squirrel Exclusion in California Garden

1/4-acre vegetable garden in Northern California, surrounded by fruit trees then live oaks. Tried everything; considering electric fencing. Asks height and considerations.

Multi-Layer Strategy

1. Perimeter fence + hot wire 6" from top (prevents climb-over). See ICWDM garden protection.
2. Tree trunk wrapping: Aluminum flashing to prevent climbing (ICWDM details)
3. Branch trimming: Prevent jumping from trees to garden
4. Legality check: Confirm electric fencing allowed locally

Complexity Note

Squirrels are persistent; requires integrated approach, not just fence.
