70% Black Shade Cloth 20 x 30 ft Mesh Tarp - Durable Garden Shade

In this review of the 70% Black Shade Cloth 20 x 30 ft mesh tarp, the bottom line is simple: this is a budget-friendly, high-coverage shade fabric good for creating cooler, protected spaces for plants, patios, and animal runs. The single biggest reason to buy is the balance of strong sun blocking - rated at a 70% shade rate - while still allowing airflow and water through. The reviewer found it most useful where large, inexpensive coverage is needed rather than for demanding, heavy-duty commercial installations.

Key Features

• 70% Shade Rate: Blocks the majority of direct sunlight to keep plants and outdoor spaces noticeably cooler while allowing 30% light through for growth.
• High Density Polyethylene: The lightweight but durable material provides good airflow and stretch, making it easy to drape over frames or tie to structures.
• Taped Edge and Reinforced Corners: Reinforcements reduce fraying at mounting points and make the cloth easier to tension without immediate tearing.
• Grommets Every 40 in: Pre-spaced metal grommets along the taped edges allow straightforward, repeatable mounting and adjustment on a frame or fence.
• Breathable, Water-Friendly Fabric: The porous weave lets water pass through and keeps air moving so plants do not overheat under the cover.
• Lock-Stitch Knitting: Construction helps prevent unraveling and holds the weave together under normal outdoor use.

Who It's For

This shade cloth is a good fit for gardeners, small greenhouse owners, and those shading patios, chicken coops, or kennels who need large-area coverage on a modest budget. It works especially well for seasonal or temporary installations where airflow and some light penetration are important.

Those who need a heavy-duty, long-term commercial fabric or thicker material for constant year-round exposure should look elsewhere; some users report the material feels thin and that heavy wind or prolonged UV exposure may shorten lifespan.

Pros & Cons

Pros

• Effective 70% shade rate provides meaningful cooling and protection for plants and outdoor spaces.

• Reinforced edges and lock-stitch knitting help delay fraying compared with untreated edges.

Cons

• Material can feel thin to some users and may show wear faster under very harsh sun or wind.
