Tips & Best Practices
- Plant sorghum 1–2 weeks after the last frost when soil is at least 65°F.
- Sorghum is more drought-tolerant than corn and a good alternative in dry areas.
- For grain, plant in rows 30 inches apart; for syrup, closer spacing works.
- Sweet sorghum can be pressed for syrup when the seeds are in the dough stage.
