Mushroom Blocks For Your Garden

Free Community Distribution Site in Lakeway supported by volunteers of the Central Texas Mycology Society.

Healthy soil starts underground—and fungi are one of nature’s most powerful tools for building thriving landscapes. Local residents are invited to pick up recycled mushroom blocks to use in their gardens, around trees, in compost systems, and throughout their landscapes.

What Are Mushroom Blocks?

Mushroom blocks are a blend of sawdust, grains, nutrients, and living mycelium (the underground fungal network that supports healthy ecosystems). After commercial mushroom growers harvest their first crop, these blocks still contain tremendous value for gardens and landscapes.

Instead of sending them to landfills, these mushroom blocks are being repurposed to help build healthier soils right here in our community.

Benefits for Your Landscape

Improve Soil Health

Mushroom blocks add valuable organic matter and beneficial fungi to the soil, helping improve structure, nutrient availability, and overall plant health.

Save Water

The mycelium inside mushroom blocks helps soil retain moisture and improve water infiltration—especially important in the rocky, clay-heavy soils common in Central Texas.

Support Trees & Native Plants

Adding mushroom blocks beneath mulch around trees and planting beds helps create healthier root environments while supporting beneficial microorganisms.

Accelerate Composting

Mushroom blocks help break down leaves, plant debris, and food scraps more quickly, making them a great addition to compost systems.

Reduce Waste

Commercial mushroom production creates significant organic waste. By reusing these blocks locally, our community helps keep valuable material out of landfills while reducing methane emissions.

Easy Ways to Use Mushroom Blocks

  • Mix into garden beds
  • Add beneath mulch around trees
  • Use in compost piles or trench composting
  • Layer into lawn replacement projects
  • Blend with mulch for fungal-rich soil building

For mulch applications, a good starting point is approximately 4 mushroom blocks per bag of mulch.

A Few Helpful Tips

  • Store and use outdoors
  • Mushrooms may continue to grow from the blocks
  • Harvest mushrooms before caps curl upward to reduce spore release
  • No gloves are required unless you have sensitivities
  • Green mold (Trichoderma) is beneficial for garden soils
