Soil pH: 6.0-7.0
Hardiness: Annual (frost-tender, extremely heat-loving)

📅 Planting Calendar (Zone 6b/7a)

🌱 Expected Yield

• Grain sorghum — per plant: 0.25-0.5 lbs grain (0.5-1 lb with good conditions)
• Grain sorghum — per 10' row: 3-6 lbs grain (8-12 plants in row)
• Sweet sorghum (syrup) — per 10' row: 0.5-1 gallon syrup (requires ~10-12 stalks per gallon)
• Sweet sorghum — per plant: 0.5-1 oz syrup (stalks yield ~8-15 gallons juice per 100 stalks; 8-10 gallons juice → 1 gallon syrup)
• Broom corn — per plant: 1-3 broom heads (multiple cuts possible from side shoots)
• Broom corn — per 10' row: 15-25 broom heads
• Notes: Grain yields on heavy clay will be lower than loam. Sweet sorghum for syrup requires a press and evaporator — significant infrastructure but extremely rewarding. Broom corn produces multiple heads per plant from tillers. Sorghum is one of the most drought-tolerant grain crops and performs remarkably well on marginal land.

🌿 Growing Conditions

Soil

Sorghum tolerates heavy clay better than most grain crops — one of its great advantages for the region. Prefers well-drained soil but handles compaction and marginal fertility better than corn. Good drainage still preferred for best yields. pH 6.0-7.0. Unlike corn, sorghum can produce respectable yields on poor, clay soils. Incorporate compost deeply to improve structure. Raised beds or ridges help in wet areas. No-till methods work well once established.

Fertilizer

• Pre-plant: Generous compost + composted manure worked in deeply
• At planting: Light all-purpose fertilizer in furrow (sorghum needs less nitrogen than corn — too much causes lodging)
• Side-dress: Light composted manure at knee-high stage if growth seems slow; go easy on nitrogen
• Note: Sorghum is a moderate feeder. Excess nitrogen causes tall, weak stalks that lodge (fall over). On heavy clay, go lighter on fertility than you would for corn. Let the soil biology do the work.

Companions

• Good: Cowpeas, soybeans, clover (legumes fix nitrogen for sorghum), sunflowers (trap crop for birds away from grain), squash (living mulch)
• Avoid: Corn (similar pests — corn earworm, fall armyworm; allelopathic competition possible)
• Note: Sorghum-sudangrass hybrids are used as cover crop companions but don't interplant with grain sorghum for harvest. Sweet alyssum attracts beneficials. Sorghum's height can provide windbreak for lower crops.

Pests

• Birds: Major pest for grain sorghum. Tight-headed varieties (like Wheatland) resist bird damage better than open-headed types. Net or use reflective tape. Plant enough to share.
• Corn earworm: Attacks seed heads; Bt spray if severe; tight-husked varieties resist
• Fall armyworm: Can defoliate rapidly; Bt spray; scout early
• Sorghum midge: Tiny orange fly that lays eggs in flowering heads; destroys grain. Time planting to avoid peak midge emergence. Destroy volunteer plants.
• Aphids (sugarcane aphid): Emerging threat; monitor undersides of leaves; insecticidal soap; beneficials (ladybugs, lacewings)
• Chinch bugs: Suck sap from stalks; more severe in dry years; maintain soil moisture
• Deer: Will browse young plants; fence or tolerate (sorghum recovers better than corn from browsing)

Diseases

• Anthracnose: Fungal; most serious sorghum disease in humid climates like WV. Reddish lesions on leaves and stalks. Plant resistant varieties. Rotate 2+ years. Destroy infected residue.
• Head smut: Fungal; replaces seed heads with dark spore masses. Seed treatment with hot water (122°F for 10 min) helps. Rotate crops.
• Grain mold: Fungal; attacks mature seed heads in wet weather. Harvest promptly when dry. Tight-headed varieties resist somewhat.
• Leaf blight: Fungal; yellow-red lesions on leaves. Improve air circulation. Rotate crops.
• Root rot: Fungal; improve drainage, especially on clay. Don't overwater seedlings.
• Prevention: Rotate 2-3 years out of sorghum/grass family. Good drainage. Resistant varieties. Clean up crop residue. Sorghum is generally more disease-resistant than corn, which is one of its advantages.

Support

• Self-supporting: Most grain sorghum varieties are sturdy and don't need staking (3-5 feet tall)
• Tall types need wind protection: Sweet sorghum (8-12 feet) and broom corn (6-15 feet) can lodge in wind. Plant in sheltered locations or use light support stakes in windy sites
• Spacing: Grain: 4-6" between plants in row, 30-36" between rows. Sweet/broom: 8-12" between plants, 36-42" between rows
• Mulching: Organic mulch retains moisture and suppresses weeds until canopy closes. Sorghum shades out weeds once established.

🏺 Heirloom Varieties

📜 Cultural History & Domestication

Origins: Sorghum was domesticated in Africa, in the Ethiopia/Sudan region, approximately 5,000-8,000 years ago. The wild ancestor, Sorghum bicolor subsp. verticilliflorum, still grows across the African savanna. Ethiopia remains the center of sorghum diversity, with thousands of landraces adapted to every microclimate from highland to desert edge.

African Heritage: Sorghum is Africa's gift to world agriculture. It fed the great civilizations of the Sahel — Ghana, Mali, Songhai — and remains a staple for over 500 million people across the continent. In Ethiopia, injera flatbread made from sorghum (and teff) is the foundation of cuisine. In West Africa, sorghum porridge, beer, and bread sustain communities. The crop's drought tolerance made it essential for food security in marginal lands where nothing else reliable grew.

Spread Through Asia: Sorghum traveled east along ancient trade routes to India by 2000-1500 BCE, where it became the jowar of the Deccan Plateau — a staple grain for millions. It reached China by the Silk Road, where it became gaoliang, grown across the dry north. In India, sorghum roti and bhakri remain everyday breads. Chinese gaoliang liquor (baijiu) is distilled from sorghum. The crop's ability to produce on marginal, dry land made it invaluable across the Asian subcontinent.

The Transatlantic Journey: Sorghum arrived in the Americas through the transatlantic slave trade, carried by enslaved Africans who brought seeds of their homeland. Enslaved people planted sorghum in garden plots throughout the Caribbean and American South, preserving both the seeds and the knowledge of how to grow and process them. Sweet sorghum (syrup cane) likely arrived through multiple pathways — both enslaved Africans and later deliberate introductions.

Appalachian Sorghum Tradition: This is where the story becomes deeply local. Sorghum syrup — often called "sorghum molasses" though it's not true molasses — became the sweetener of Appalachia. When cane sugar was expensive and inaccessible in the mountains, sorghum syrup was homegrown, homemade, and essential. Every fall, communities gathered for sorghum-making days — pressing the cane through horse-drawn or mule-drawn presses, boiling the juice in evaporator pans over wood fires, skimming the green scum and impurities, and bottling the result: rich, amber, complex syrup that tastes like honey, caramel, and earth.

Sorghum-making was a social event. Families came together. Children watched. Elders supervised the boil. The smell of cooking sorghum marked autumn in the hills as surely as falling leaves. This tradition persisted well into the 20th century and is experiencing a genuine revival — new sorghum presses are being built, young farmers are planting syrup cane, and the Appalachian Sorghum Festival keeps the knowledge alive.

Broom Corn Tradition: Broom corn (Sorghum bicolor var. technicum) has its own deep history. The Shakers industrialized broom-making in America starting in the 1790s, but the craft of making brooms from sorghum dates back at least 5,000 years. The broom corn industry was centered in the Midwest — particularly Kansas, which was once the broom corn capital of the world. Every broom was once a sorghum plant. The craft nearly died with the rise of synthetic brooms, but broom-making is being revived as a handcraft and heritage skill.

Mennonite and Amish Preservation: Mennonite and Amish communities preserved sorghum syrup traditions through generations when the broader culture forgot. The Mennonite sweet sorghum variety carried in this guide represents that chain of preservation — communities that never stopped pressing cane, never stopped making syrup, never let the knowledge die. Their sorghum mills remain operational, and their syrup is prized for its complex, rich flavor that industrial syrups cannot match.

Modern Decline and Revival: Sorghum production in the US declined dramatically through the 20th century as cane sugar and corn syrup replaced sorghum syrup. Grain sorghum (milo) survived as animal feed in the Great Plains but was largely invisible as human food. The revival of heirloom grains, the local food movement, and the rediscovery of gluten-free cooking have brought sorghum back. Sorghum flour is one of the best gluten-free flours — naturally sweet, nutritious, with a mild flavor. Sorghum syrup is increasingly recognized as a unique artisanal product. The tradition is alive again.

Appalachian Note: For Zone 6b/7a, sorghum is not just a crop — it's heritage. The WV Sorghum Festival in Raleigh County celebrates this. Sorghum grows well on our heavy clay when many other grain crops struggle. It needs less nitrogen than corn and handles drought that would ruin a corn crop. On marginal land — and WV has plenty of that — sorghum outperforms. Plant it. Press it. Boil it. Taste the history in every spoonful.

🌾 Seed Saving

Method: 1. Select healthy, vigorous plants with desirable traits (grain quality, syrup sweetness, head size, drought tolerance, earliness) 2. For grain sorghum: let seed heads mature fully on the plant — seeds should be hard and dry. Cut heads when seeds resist thumbnail pressure 3. For sweet sorghum: mark exceptional plants early (before processing) for seed saving. Let those plants mature fully rather than pressing 4. For broom corn: select for head length, fiber quality, and color 5. Cut seed heads with 6-12 inches of stalk attached 6. Hang heads upside down in a dry, well-ventilated area for 2-3 weeks 7. Thresh by banging heads against the inside of a clean barrel or by rubbing between gloved hands 8. Winnow to remove chaff — pour seeds between bowls in a breeze or use a fan 9. Ensure seeds are completely dry (test by biting — should be hard, not doughy) 10. Store in glass jars or paper envelopes in cool, dry, dark place 11. Add desiccant if humidity is high

Isolation Distance: - Cross-pollinating: Sorghum is primarily self-pollinating but wind can carry pollen significant distances - Minimum: 920 feet (1/6 mile) between varieties for home use - For seed sale: 1/2 mile or bag heads before pollen shed - Note: All sorghum types (grain, sweet, broom) can cross-pollinate. If saving seed, grow only one variety or isolate. Broom corn crossed with grain sorghum produces poor brooms AND poor grain — keep them separated.

Viability: 3-5 years under proper storage. Germination rates decline after year 3.

Special Notes: - One seed head yields 500-2,000 seeds depending on variety - Save from 10-20 plants for genetic diversity (sorghum has moderate genetic variation) - Select for the trait you're growing: grain quality for grain types, sugar content for sweet types, head length and fiber for broom types - Sweet sorghum seed saving requires sacrifice — you must let plants mature fully rather than pressing for syrup - Birds love sorghum seed; bag heads with paper bags or netting as they mature - Sorghum seed can harbor head smut spores — hot water seed treatment (122°F for 10 minutes) reduces disease transmission - Do not save seed from plants showing signs of anthracnose or other disease
