Defender Guards - Biodegradable Tree Guard / Vine Guard

Defender-Guards provide a cost-effective, eco-conscious way to protect young vines and trees from environmental challenges like wind, sunlight, and herbicides. Made from biodegradable paperboard, these sleeves help create a favorable microclimate and support a smooth transition from the nursery to the field, encouraging strong early growth.

Free from glues and harmful chemicals, Defender Guards are designed to promote sustainable farming practices while keeping soil and crops safe. Made with a milk-carton-style paperboard, they naturally decompose in the field, offering an environmentally friendly alternative to conventional plastic guards.

Sustainability That Performs 

Our protectors typically last 18 to 24 months in outdoor conditions, providing reliable performance while naturally breaking down over time. By choosing Harvest Horticulture, you help reduce plastic waste and lower your operation’s carbon footprint - without compromising on plant health or operational efficiency.

Faster Establishment

Our sleeves create a protective microclimate that helps plants establish more quickly by shielding them from hail, wind, and other environmental stressors.

Protection

The sleeves act as a physical barrier against rodents, pests, and many weed control mechanisms. 

Reduced Herbicide/Pesticide Exposure

When herbicides or pesticides are used nearby, our sleeves help reduce overspray and protect crops from chemical exposure.

Cost Efficiency

By acting as a weed barrier, our sleeves can reduce maintenance, pesticide use, and plant mortality—helping trees and vines produce up to a year sooner.

Root Strength

By directing vertical growth and reducing competition for water, the sleeves encourage strong root development both above and below ground.
