Greenhouse/ High Tunnel Production

WeedGuardPlus is a sturdy 100% biodegradable paper mulch that effectively suppresses weeds throughout the growing season without the use of petroleum or corn-based plastics.

WeedGuardPlus is especially well suited for a greenhouse and high tunnel production.

  • WeedGuardPlus is permeable to water and air (unlike black plastic mulch), making the product highly suitable for use with overhead irrigation.
  • Since WeedGuardPlus allows air to escape, you avoid the extreme elevated soil temperatures associated with black plastic.
  • Finally, you do not need to remove or dispose of WeedGuardPlus at the end of the season. The product is 100% biodegradable and can be incorporated into the soil at the end of your growing cycle. No clean-up and disposal steps means a big savings in time and labor.

WeedGuardPlus is USDA certified as 100% Bio-Based and is OMRI certified for organic production.

Product Options

With multiple weights, widths and length of rolls, there is a WeedGuardPlus product that fits your production needs.

Be sure to check out the creped, pre-punched rolls and fertilized options.

Creped rolls allow for greater strength and plasticity, providing easier machine application using a standard mulch layer. (The creping allows the paper to contour to the shape of the bed, providing continuous soil-to-mulch contact.)

Our Installation section gives you a step-by-step look at the simple adjustments needed to ensure easy application for whatever product you choose.

Pre-punched mulches come in a 5 rows, double rows, and single row options. This pre-punching provides consistent and precise plant spacing, and is a tremendous time saver.

The fertilized rolls contain a 5-5-5 fertilizer embedded within the paper itself. This fertilizer slowly releases into the soil as the season progresses, providing continuous feeding for plants.

WeedGuardPlus fertilizer is designed for targeted, slow release: this ensures greater plant uptake and reduces losses to leaching and volatilization. This increased fertilization efficiency is a big benefit to the bottom line.
