Practical C&M Garden tips
- Raised beds and dark, well-drained soil often warm sooner than surrounding ground.
- Use the short-term forecast—not just the calendar—before planting or covering tender crops.
- Protect tender crops with row cover, a cloche, or a simple overnight cover when frost threatens.
- Midwest springs can be wet and slow to warm, so soil condition matters as much as the date.
- These are estimates only; keep a little flexibility in your planting plan.
