Cupertino Arborist, Land & Pest

A Legacy of Tree Care and Arborist Consulting Excellence in Silicon Valley

Mike and Leo of Evans West Valley Spray have watched Cupertino grow from orchards into a tech hub over their decades in business. Since 1991, they’ve helped preserve the area’s remaining heritage trees while supporting healthy growth of new landscapes across the city’s evolving neighborhoods and corporate campuses.

“We learned this business the old-school way,” Leo explains, “but we’ve stayed current with the latest science and technology. That combination of traditional knowledge and modern techniques helps us solve problems other companies can’t touch.”

Arborist Services for Cupertino’s Trees

Tree and Deep Root Diagnostics
Our diagnostic process starts below ground, examining root systems and soil conditions that impact tree vitality. We spot early warning signs that others miss with technology few companies have: sonic tomography and resistograph analysis.

Life-Saving Technology
We’re the only local provider offering sonic tomography – technology that lets us see inside trees without harming them. For Cupertino’s heritage trees, this non-invasive approach can mean the difference between necessary treatment and needless removal.

Complete Tree Health Management
Working with Cupertino’s strict tree protection ordinances, we provide:

• Health assessments based on decades of local experience
• Site-specific preservation strategies
• Scientific risk evaluation
• Property-wide tree inventories

We understand Cupertino’s specific challenges – from the impact of hardscaping on root systems to the specific needs of native oaks in urban settings. This deep local experience shapes every recommendation we make.
