What to plant this week in Halifax, NS
With the last frost average for Halifax hovering around April 21, your week is all about holding off on spring sowings while getting a final harvest from your garlic and daikon radishes before the summer heat sets in. The Atlantic air brings high humidity that will stress these root crops if you don't pull them promptly.
The next 7 days
Halifax, NSGrowing in Halifax right now
- Do not plant any cool-season seeds yet; with soil temperatures still dipping near -10°F lows, early sprouts will be killed by a late April cold snap typical of the Maritimes.
- Harvest your Daikon Radish immediately as the ground warms, ensuring crisp roots before they go woody in this humid microclimate.
- Finish planting Garlic cloves now if you missed the window last fall, but keep them shallow to avoid heaving from heavy spring rains common on the peninsula.
- Wait until mid-May before transplanting any tender greens, allowing the soil to warm past the critical threshold for Zone 6a survival.

Seasonal tips
- Apply fresh mulch now to retain soil moisture as temperatures rise.
- Test soil pH before adding any compost or amendments for new transplants.
- Keep a close eye on emerging seedlings to protect them from late spring fluctuations.
Pest & disease watch
- Watch for carrot rust fly activity starting now as temperatures rise above freezing, which can decimate nearby root crops even if they are mature.
- Monitor garlic patches for spring bulb mites that thrive in our damp Maritime summers before they cause significant damage to developing heads.
- Check drainage around garden beds after heavy rains, as waterlogged clay soils common in Halifax neighborhoods increase the risk of fungal rot on stored roots.
Watering this week
Water deeply but less frequently now that the soil is warming up, encouraging strong root development.
Harvest Daikon Radish promptly before the heat sets in to ensure the best crunch and flavor.
Halifax gardening questions
3When is it finally safe to sow tomatoes and peppers outdoors in Halifax?
You must wait until at least May 15th when the soil has consistently warmed up following our typical late April frost dates. Putting plants out any earlier risks losing them to a sudden drop below zero degrees.
How do I protect my garlic harvest from rotting during Halifax's rainy spring?
Pull your bulbs gently and cure them in a warm, dry, airy spot like a garage or shed for three weeks before storing. Never store wet garlic directly on concrete floors where condensation will encourage mold.
Why are my Daikon radishes turning tough even though they are ready to eat?
The rapid temperature rise and high humidity typical of late April in Nova Scotia cause roots to bolt quickly if left too long. Harvest them within a few days of reaching full size for the best crunch.
