Compost in Calgary — Bulk Garden Compost & Soil Amendments

Calgary soil tends toward heavy clay (locally called "gumbo") with low organic content — exactly what compost is designed to fix. Dirtlink connects gardeners and contractors with Calgary compost suppliers and producers in one searchable place.

Types of compost

  • Garden compost — fully composted plant material, the default for gardens and beds.
  • Leaf mulch — partially composted leaves, slower-release.
  • Mushroom compost — high in nutrients, used to amend lawns and gardens.
  • Manure compost — composted animal manure (verify source — well-composted is essential).
  • Soil amendment blends — compost mixed with sand or peat for specific applications.

How much compost do you need?

  • New garden bed (4" amendment): 1 cubic yard per 80 sq ft
  • Top-dressing existing lawn (1/2" depth): 1 cubic yard per 650 sq ft
  • Raised bed mix (compost + topsoil): ~25–50% compost by volume

Frequently asked questions

Is bagged or bulk compost cheaper in Calgary?
Bulk by far for any application over a couple cubic feet. Bagged is fine for small container gardens.
What's the best compost for Calgary clay soil?
Garden compost or a sand/compost blend — both improve drainage and add organic content.
Can I use horse manure compost?
Yes if fully composted (no smell, dark crumbly texture). Fresh manure can burn plants and carry weed seeds.
How much does a yard of compost cost in Calgary?
Pricing varies by type and supplier. Live listings show current pricing.
When should I add compost to my garden?
Spring before planting and fall after harvest are the two main windows.
