- 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).

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.
