When to Plant Watermelon in North Carolina
Plant watermelon in North Carolina after frost danger has passed and soil is at least 65 degrees F. North Carolina has a wide climate range, from the warmer coastal plain to the cooler mountains. The best planting date depends on your region, not just the state name.
NC State guidance places watermelon planting after frost, broadly from mid-April into June. Its central North Carolina market-garden calendar lists transplants from May 1 through July 1. Coastal gardens may warm earlier, while mountain gardens may need to wait longer because of elevation and frost risk. Use the watermelon by zone guide with your local frost date.
North Carolina Timing Notes
- Start transplants indoors if your mountain season is short.
- Direct sow (plant seeds straight in the garden) when soil is warm and the forecast is settled.
- Give vines full sun and plenty of space.
- Water deeply during fruit development.
Is It Too Late to Plant Watermelon in North Carolina?
