One of the key secrets to your EarthBox® container gardening success is the EarthBox® Mulch Cover! In addition to keeping unwanted weeds and some pests out, the Mulch Cover helps conserve water and keep nutrients in, all while protecting your plants’ growing environment against the elements. Made from durable, professional-grade agricultural film, it's one of the most important elements of the EarthBox® gardening system.

The EarthBox® Mulch Cover serves several critical functions to control and protect the system's environment:

  • Keeps rain out of the growing media to prevent crucial nutrients from being washed away
  • Prevents evaporation and conserves water
  • Stops weeds from transplanting in the system, which would otherwise compete for space, water, and nutrients against your crops
  • Helps deter some insects and other pests from burrowing or digging in the growing media
  • Depending on the climate and which color is face up, the mulch cover helps to attract or reflect sunlight. This assists in controlling the temperature of the growing media. Use the white side up in hot, dry climates to prevent young seedlings from dying; or in contrast, help warm the soil to stimulate growth by using the black side up in cooler climates

EarthBox® Mulch Covers are sized accordingly for your growing system.

Do I really need to use the Mulch Cover?

Yes! The Mulch Cover is what protects the growing environment of the entire EarthBox® gardening system. It helps conserve water by limiting evaporation, and it prevents heavy rains from washing away all the plants’ fertilizer and nutrients. The Mulch Cover also protects the growing media from weeds and pests. Place the cover on the system before planting and leave it on until your growing season is over and you’re ready to remove the plants and clean up the growing system.

Always use the Mulch Cover, even in very hot climates. If your local temperatures are typically in excess of 85° F during the peak growing season, place the Mulch Cover on the system with the white side facing up. This will reflect the sun so small plants don’t become stressed from the heat.

For cooler climates where early growing season temperatures may still be too cold for some plants, place the Mulch Cover on the system with the black side facing up. This will attract the sun and warm the growing media to help small plants grow.

Do you have Red Mulch Covers?

Red Mulch Covers are being phased out, and we no longer have Red Mulch Covers for the EarthBox® Original gardening system available. Red Mulch Covers for the EarthBox® Junior gardening system are available while supplies last, and can be found in our Clearance section.

How long will the Mulch Cover last?

The EarthBox® Mulch Cover is made from professional-grade agricultural film and is made to last for a single growing season, approximately 3-5 months. Each Mulch Cover is hand-sewn in the U.S.A. with a rubber-based elastic to secure the cover around the edge of the container, which will naturally degrade with exposure to UV light.

If growing indoors, the Mulch Cover will last much longer.

What is the Mulch Cover made from?

The EarthBox® Mulch Cover is made from reversible, professional-grade agricultural film, which is #4 plastic called Low-Density Polyethylene (LDPE). LDPE is food-safe.

The EarthBox® gardening system is a low-maintenance, fail-proof design determined to fill the needs of the home gardener of any skill level. Since not all home gardeners live in the same area, there are many challenges to finding the perfect container gardening solution for everyone, but the EarthBox® system does just that. Combining science—and a ton of testing—with great design and American manufacturing, the EarthBox® container gardening system was designed by applying a variety of tried-and-true commercial growing concepts to a small footprint to produce better results than traditional in-ground gardens. The following diagram explains in detail how the EarthBox® growing system components all operate together:
