BioAdvanced 12 Month Tree and Shrub Protect and Feed II - YearLong

In this review the BioAdvanced 12 Month Tree and Shrub Protect and Feed II is evaluated as a convenient, dual-action option for homeowners who want long-lasting pest control without frequent treatments. The single biggest reason to buy is its combination of a slow-release fertilizer and systemic insect protection that claims to protect trees and shrubs for up to a year after one application. For gardeners who prefer granules over sprays, this product delivers ease of use and root-to-leaf coverage that targets common pests while improving plant health.

Key Features

• 12 month protection: One application is formulated to kill listed insects and prevent new infestations for up to a year, reducing the need for repeated treatments.
• Pest control: The granules target pests such as Japanese beetles, Emerald Ash Borers, leafminers, aphids and caterpillars for broad outdoor insect control.
• Systemic protection: Active ingredients are absorbed by the roots and translocated through the plant to protect leaves, stems and new growth.
• Slow-release fertilizer: The product includes plant food that slowly releases nutrients to improve the overall health and vigor of trees and shrubs.
• Easy application: Ready-to-use granules require no spraying and can be applied to outdoor trees, shrubs or containerized plants for simple treatment.

Who It's For

This product suits homeowners and gardeners who want a low-effort, long-duration solution to common tree and shrub pests and who prefer granules to liquid sprays. It is also a good fit for those who want combined feeding and pest protection in a single application, especially on established ornamental trees and shrubs.

It is less appropriate for people needing immediate contact kill of visible insects on foliage or for those who require organic or non-systemic controls; professional applicators seeking concentrated or large-scale commercial formulations may also look elsewhere.

Pros & Cons

Pros

• Provides extended, system-wide protection for up to a year with a single application.
• Combines insect control and slow-release fertilizer to improve plant health while preventing pests.
• Ready-to-use granules are rainproof once absorbed and eliminate the need for spraying.

Cons

• Some customers find the product pricey compared with single-purpose options, so cost may be a consideration.
• As a systemic granular treatment, it does not provide an instant knockdown on visible insects the way a contact spray would.

Our Verdict

For homeowners seeking a hands-off, long-lasting treatment that both feeds and protects trees and shrubs, this product represents good value when combined benefits are considered.
