What to plant this week in Zone 1a
In Zone 1a, the ground remains frozen well into mid-June, so all gardening activities must wait until after your last frost on June 15. There are no plants to sow or harvest this week as we are still in deep winter dormancy.

Seasonal tips

- Plan your spring planting calendar now, aiming for mid-June sowing dates once the soil thaws.
Keep watch
Pest & disease watch
- Monitor for early signs of rodent damage to stored bulbs or tender seedlings if any are out of doors.
- Check greenhouses for overwintering aphids before they can move outside as temperatures rise.
Water
Watering this week
Do not water outdoor plants until the soil has fully thawed and there is a risk of root rot from ice.
