Quick answer
Use the EarthBox Mulch Cover as a durable, reusable barrier that blocks sunlight to prevent weeds, while conserving water and keeping nutrients in your container garden.
Why the Mulch Cover works better than loose mulch
Loose mulches like straw or bark can blow away, break down quickly, or attract pests. The EarthBox Mulch Cover is a single-piece, UV-resistant fabric that stays put season after season. It creates a physical barrier that stops weed seeds from germinating, while still allowing water and air to reach the soil through the EarthBox watering system.
Step-by-step installation
- Prepare the EarthBox: Fill your EarthBox with potting mix and fertilizer strip as usual. Water the box thoroughly before placing the cover. Installing on dry soil can cause the cover to shift when you water later.
- Position the Mulch Cover: Lay the cover over the soil surface, aligning the precut planting hole with the center of the box. Tuck the edges snugly into the rim of the EarthBox. If the cover is loose, it can billow in wind and let light reach the soil.
- Cut additional planting holes: Use scissors or a knife to make small X-shaped slits for transplants or seeds, spacing them according to your crop’s needs. Do not cut more holes than necessary. Too many holes reduce the cover's weed-blocking effectiveness.
- Secure and maintain: After planting, check that the cover lies flat against the soil. Over time, brush off debris and rinse occasionally to keep it reflecting light and heat evenly. A dirty cover may hold moisture against the soil, promoting mold.
