Sorghum–sudangrass hybrid
Sorghum × drummondii (warm-season grass)
Nutrients & rotation
After sprawling cucurbits or tired corn rows, a tall warm grass builds huge carbon fast and shades aggressive annual weeds — demands heat and water.
Small-garden overkill unless you have space and mower time — great for empty lots or large community beds.
In the garden
- Needs 65°F+ soil and steady moisture; drill or broadcast in wide rows.
- Mow before seed heads to avoid volunteers; watch frost — kills with cold in temperate zones.
Timing
Late spring through midsummer where the season is long enough for meaningful growth.
Caveats
- Can be allelopathic when fresh — incorporate or compost before sensitive follow crops.
