Arugula in Zone 3a & 3b

Eruca sativa

When to plant arugula in zone 3b

Zones 3a and 3b share the same average frost dates in our data, so this page covers both.

Method: Direct sow: Direct-sow outside. Arugula doesn't transplant well, or doesn't need the extra time indoors.

Start indoors	Not typically started indoors
Direct sow / transplant outside	Apr 25–May 2
Estimated harvest	Jun 4–Jun 11 (~40 days after direct-sowing)

Spacing: 9 per square foot (square-foot-gardening spacing). Mature height: 0.5-1.5 ft.

Arugula is about as fast as salad greens get, direct-sown and ready to harvest in around 40 days, with a peppery bite that gets sharper as the weather warms.

How arugula fits zone 3's season

Zone 3b's frost-free window runs about 98 days, from May 30 to September 5. Arugula needs about 40 days from sowing to first harvest.

Good companions

Carrot: Fast-maturing, non-competing salad-garden interplant.
Lettuce: Similar light/water needs; grown together as cut-and-come-again greens.
