MegaMulch Compressed Brick (2.5 Cu Ft Once Expanded)

Sustainable, Water-Wise Mulch for Weed Control and Soil Health

The PlantBest MegaMulch Compressed Brick is an eco-friendly, coir-based mulch made from renewable coconut husks. Just add water, and this compact brick expands to approximately 2.5 cubic feet—ready to suppress weeds, retain moisture, and protect soil in your garden beds.

Designed for organic gardeners and sustainable growers, MegaMulch provides excellent coverage while slowly breaking down to enrich the soil. It’s ideal for vegetable beds, flower borders, fruit trees, or erosion-prone areas.

Key Benefits:

  • Expands with Water: One compact brick expands sixfold—covering up to 20 sq ft at 1.5" depth.
  • Suppresses Weeds: Blocks sunlight to minimize weed growth naturally.
  • Retains Moisture: Coir soaks up water and slowly releases it, reducing the need for frequent irrigation.
  • Controls Erosion: Great for slopes and bare spots where runoff is a concern.
  • Improves Soil Over Time: Breaks down into organic matter to support soil structure and microbial life.
  • Naturally Biodegradable: No synthetic materials—just 100% coconut husk chips.

versatile

Excellent mulch. Easier to carry than a big bulky bag of mulch. Expands easily, I left mine in a garbage can overnight with water. It was ready to use the next day and I just wheeled it over to the front garden bed. Reddish-brown color stands out and makes the bed look tidy. One brick covered my entire front garden bed, which is about 10'x 2'.

great stuff

This is a great way to mulch. There aren't any big bags to lug around & then dispose of when done mulching.
Great for the environment.
And it does exactly what the packaging describes.
Add water & it expands.
Not much easier than that.
