The Most-Asked Question in Michigan Gardening
Michigan Tomato Planting — By Zone and City
Tomatoes are Michigan's most popular home garden crop — and the source of the most anxiety. Plant too early and a late frost kills them. Plant too late and you miss weeks of harvest. Here's the answer, zone by zone and city by city.
The rule: Tomatoes go in the ground 2 weeks after your average last frost date — when soil at 4-inch depth reaches 60°F. Rushing this costs you weeks of stunted growth. Waiting one extra week costs nothing.
Tomatoes planted after soil temps reach 60°F establish faster and outperform plants rushed into cold ground.

Common Questions
Michigan Tomato FAQ
Can I plant tomatoes in late April in Michigan?
In zone 6b (Detroit area), late April planting is possible with protection — row cover or cloches. Soil temperature must be at least 55°F and you should be prepared to cover plants if temps drop below 40°F at night. It's a calculated risk that gains 1–2 weeks.
Why do my Michigan tomatoes flower but not set fruit?
The most common cause in Michigan is temperature. Tomatoes drop flowers when nighttime temps fall below 55°F or daytime temps exceed 90°F. In early June, cool nights are usually the culprit — be patient, fruit set improves as temperatures stabilize.
Should I use a cage, stake, or trellis for Michigan tomatoes?
Heavy-duty cages (not the flimsy wire ones) work well for determinate varieties. For indeterminate varieties (most heirlooms), a sturdy stake or Florida weave trellis keeps plants manageable through Michigan's summer storms and wind.
