When to Plant Garlic in Regina, SK

- Mulch with 3–4 inches of straw after the first hard freeze to insulate through winter.
- Remove garlic scapes (the curling flower stalks) in June from hardneck varieties to redirect energy to the bulb.
- Harvest when the bottom 3–4 leaves turn brown — typically June in most regions.
