Can You Stop Oak Trees from Producing Acorns? Options and Alternatives

Acorn crops vary yearly. No simple prevention exists. Floral growth regulator sprayed at bloom can reduce acorns, but timing is tricky (oak flowers are inconspicuous), coverage must be complete (requires professional equipment for mature trees), and treatment is annual—costly over time. Simpler solution: mulch under the tree to eliminate mowing and acorn cleanup.
