Harris Seeds Plastic Mulch

While black mulch primarily warms the soil, this red plastic mulch is engineered to reflect specific far-red light wavelengths back into the plant canopy. This biological trigger encourages faster development and higher yields, specifically for crops like tomatoes and strawberries.

This product is specifically optimized for cooler, northern climates where maximizing early-season heat and light reflection is critical. In very hot regions, the light-reflecting properties may cause excessive soil temperatures, potentially stressing your plants.

The mulch is made from 1.0 mil embossed plastic, which provides decent durability for a single growing season. However, it is designed as a disposable agricultural film and will likely degrade or tear if you attempt to remove and reinstall it for subsequent years.

Each roll measures 4 feet by 100 feet, providing a total coverage area of 400 square feet. This is sufficient for a substantial garden bed of tomatoes or strawberries.

While it is specifically engineered to boost the growth of tomatoes and strawberries, the far-red light reflection can benefit other fruiting crops that thrive in early-season warmth. However, you will see the most significant results when using it for its intended primary applications.
