What to plant this week in Regina, SK
Regina gardeners are currently in the critical window before our average last frost of May 15, meaning any tender plants like French Marigolds or Petunias must wait for warmer soil. This week offers a perfect opportunity to sow hardy Garlic cloves now while preparing your beds for the rapid spring growth expected by late May.
The next 7 days
Regina, SKGrowing in Regina right now
- Regina's heavy clay soils are notorious for staying frozen well past mid-May; ensure drainage paths are cleared before planting Spring Bulbs or early transplants.
- Avoid disturbing wet, frozen ground immediately after a thaw to prevent soil compaction and root damage in our alkaline prairie soils.
- Watch for sudden temperature swings typical of the Prairies; use row covers on young seedlings if an unseasonal cold snap threatens before May 15.
- Harvest your Winter Squash now while weather is mild, as Regina's hard freeze by September 20 can crack rinds and ruin storage quality.

Seasonal tips
- Clear away spent vegetable plants now to prevent disease carryover into winter.
- Divide perennials like borage, garden verbena, and zinnia while the soil is still warm.
- Gather all fallen leaves and debris from around your garlic patch to keep it clean.
Pest & disease watch
- Watch for early aphid colonies on Brassicas like Brussels Sprouts as temperatures rise above 4°C.
- Monitor for cutworms threatening young Pole Bean seedlings planted in the last few weeks.
- Beware of fungal leaf spots on carrots and parsnips if this week brings excessive moisture to our low-lying garden areas.
Watering this week
Reduce watering significantly now that harvest is underway, allowing the soil to dry out between the last few waterings before frost.
Mark your tomato and pepper locations with stakes so you can easily find them when spring planting begins next year.
