October garden jobs

Plant garlic on the coast; mulch already-planted garlic inland once soil chills.
Clear beds and compost healthy material only.
Cure and store squash, onions and potatoes properly.
Drain hoses and irrigation before the first hard freeze.
Take a soil test now if you plan to amend before spring.

Common October mistakes

Mulching garlic before the ground has cooled, which encourages soft growth and rot.
Leaving hoses charged through a Prairie freeze.
Composting blighted tomato and potato foliage.
Leaving Prairie beds uncleared into freeze-up, which makes spring far harder.

Frequently Asked Questions

Is October too late to plant garlic in Canada?

On the coast, no — mid-October is ideal. In Central Canada and the Prairies, October is the outside edge; mid-September to early October is safer.

What should I do with empty beds?

Sow a cover crop where the season allows, or mulch heavily. Bare soil over a Canadian winter loses structure and nutrients.

When should I mulch garlic?

After the soil surface has chilled but before it freezes hard — typically late October to November depending on your region.
