The next 7 days
Regina, SKGrowing in Regina right now
- The Regina clay-loam soil freezes solid down to two feet deep; avoid any late-season digging that could damage winter-killed roots once the thaw begins in May.
- With average minimums hitting -35°F, ensure all cold frames and hoop houses are reinforced against extreme wind loads before the next blizzard arrives.
- Keep indoor humidity low when starting seeds indoors to prevent damping-off, as Regina's dry continental climate can dehydrate soil quickly even inside heated homes.

Seasonal tips
- Apply fresh compost to beds now to warm the soil before the growing season begins.
- Clear winter debris from garden borders to prevent harboring late-season pests.
- Prepare hardy perennial beds by dividing crowded clumps if they are still dormant.
Pest & disease watch
- Spider mites may still linger on overwintered houseplants if heating is cranked up too high and windows are sealed tight against the cold.
- Late-season aphids or cabbage looper larvae could survive under snow cover in protected areas, so scout carefully as temperatures fluctuate near zero.
Watering this week
Water deeply only when snowmelt is insufficient, as frozen ground prevents absorption until the soil thaws.
Start indoor seedlings of cool crops like peas or lettuce now to be ready for transplanting in late May.
Regina gardening questions
3When should I start my tomato seeds indoors for a Regina garden?
For our zone 3b climate with a May 15 average last frost, aim to sow tomatoes indoors in early March to get them outside by mid-May. Starting too late risks stunting growth before the summer heat arrives.
Can I plant anything outdoors right now in Regina?
No outdoor planting is advisable until after the May 15 frost date passes, as sudden freezing can kill tender seedlings instantly. Wait for consistent soil warmth rather than relying on a specific calendar day this week.
How do I protect my vegetable garden from Regina's extreme cold snaps?
Cover exposed plants with thick row covers or burlap during severe freezes, though most annuals will likely die back anyway before May. Focus your energy on preparing the soil structure and gathering supplies for when the thaw finally arrives.
