Pinnacle Mercantile 450 Pack Dissolving Garden Staples - Biodegradable

In this review the Pinnacle Mercantile 450 pack of 6 in dissolving garden landscape staples is evaluated for gardeners who want a temporary but sturdy anchor for fabric, sod, or seed mats. The single biggest reason to buy is the combination of immediate holding strength from 11 gauge steel with a designed, gradual dissolution in soil, offering a lower-impact option for projects where permanent metal anchors are not desired. The review highlights real-world use, biodegradability expectations, and suitability for common yard and garden tasks.

Key Features

• Non-galvanized steel: Allows the staple to rust and gradually dissolve in 2-5 years depending on soil conditions, reducing long-term metal left in the ground.
• 11 gauge strength: Provides strong, immediate holding power to keep landscape fabric, sod, or netting secure during installation and establishment.
• Quantity: A 450-count pack supplies enough staples for multiple small-to-medium projects around a typical yard or garden.
• Moisture-activated texture: Rain and soil moisture promote rusting that increases surface texture and holding power before the staple degrades.
• Made in USA: Manufactured domestically and produced by a 501(c)(3) nonprofit that employs Americans who are blind.

Who It's For

These dissolving landscape staples are best for homeowners, landscapers, and community gardeners who want a temporary anchoring solution that will not remain permanently in the soil. They work well for installing biodegradable landscape fabric, anchoring sod rolls, securing grass seed sheets, or holding down netting while vegetation establishes.

Those who need permanent, non-corroding stakes for long-term installations or saltwater-exposed coastal projects should look elsewhere; galvanized or stainless options will resist rust indefinitely and provide long-lasting anchors where dissolution is undesirable.

Pros & Cons

Pros
