The cooler temperatures and longer daylight hours create ideal conditions for certain crops to thrive. Planning ahead ensures a productive and rewarding garden season.
Vegetables to Sow in Early May
- Root Vegetables: Carrots, beets, and radishes can be directly sown into the soil. Choose cold-tolerant varieties for best results.

Tips for Successful Early May Planting
In Zone 4, it’s essential to monitor the last frost date, which typically falls between late April and early May. Use row covers or cold frames to protect young plants from unexpected frosts. Prepare your soil by adding compost and ensuring proper drainage. Water consistently and mulch to retain moisture and suppress weeds. With proper planning and care, your early May planting will set the stage for a bountiful garden season.
