Zone: 6b/7a
Soil: Heavy clay
Understanding Sorghum
Grain Sorghum vs. Sweet Sorghum
Grain Sorghum (Milo): - Grown for seed (like corn for grain) - Shorter plants (3-5 feet) - Seed heads at top - Uses: Flour, animal feed, gluten-free products - Harvest: When seeds mature (90-120 days)
Sweet Sorghum (Sorghum Cane): - Grown for syrup (like sugarcane) - Taller plants (6-12 feet) - Juice in stalks (sweet) - Uses: Sorghum syrup, molasses alternative - Harvest: When stalks are mature (100-120 days)
For The Loop Farmstead: Grow both. Grain sorghum for flour and feed. Sweet sorghum for syrup. They're the same species, different cultivars.
Sorghum Types
Caudatum: - Large, round seeds - Common in US grain sorghum - Good for feed, flour
Durra: - Indian/African origin - Popping sorghum (like popcorn) - Food grade
Bicolor: - Sweet sorghum types - Syrup production
Caudatum-Durra Crosses: - Modern grain varieties - Improved yield, quality
2. Black Amber
Type: Heritage Grain Sorghum
Days to Maturity: 100-110 days
Source: Baker Creek Heirloom Seeds, Seed Savers Exchange
Characteristics: Dark seeds, tall plants, traditional variety, dual-purpose (grain + forage)
Uses: Flour, feed, forage
Why Grow It: Black Amber is an old-time sorghum variety with dark seeds. It's productive, drought-tolerant, and historically significant. The dark seeds indicate higher antioxidant content (anthocyanins). Black Amber is sorghum with a story.
Clay Soil Performance: Good.
4. Redlan
Type: Modern Grain Sorghum
Days to Maturity: 95-105 days
Source: Regional suppliers, farm supply
Characteristics: Reddish seeds, improved yield, drought-tolerant
Uses: Flour, feed
Why Grow It: Redlan is a widely grown modern sorghum. It's adapted to the Plains but grows well in the East. The red seeds have antioxidants. Redlan is a workhorse variety.
Clay Soil Performance: Good.
6. Keller
Type: Heritage Sweet Sorghum
Days to Maturity: 105-115 days
Source: Seed Savers Exchange, heritage seed sources
Characteristics: Traditional variety, good sugar content, heritage genetics
Uses: Syrup, chewing cane
Why Grow It: Keller is an old-time sweet sorghum variety. It was grown on Southern farms for syrup before commercial sweeteners took over. Growing Keller preserves agricultural heritage.
Clay Soil Performance: Good.
Growing Sorghum on Clay Soil
Site Preparation
Timing: - Plant: Late spring (May-June) - Soil temp: 65°F+ at planting depth (sorghum needs warm soil) - After corn planting time (sorghum is more heat-demanding)
Preparation: 1. Clear previous residue 2. Till or broadfork to prepare seedbed 3. Add compost if soil needs building 4. Sorghum establishes best in warm, well-prepared soil
Note: Sorghum is slower to establish than corn. Good seedbed preparation matters.
Planting
Seed Rate:
For Grain: - 8-12 lbs per acre (much smaller seeds than corn) - Small scale: 0.5-1 oz per 100 sq ft - Thin to final spacing
For Syrup: - Similar rate - Slightly closer spacing
Method:
Direct Seed: 1. Plant 1/2-1" deep (smaller than corn) 2. Spacing: 4-6" between plants, 30-36" between rows 3. Or plant in hills (like corn)
Clay-Specific Notes: - Sorghum tolerates clay well - Ensure good drainage (sorghum doesn't like wet feet) - Plant when soil is warm (delays germination in cool clay)
Growing Season
Timeline: - May-June: Planting - Weeks 1-2: Germination (slow in cool soil) - Weeks 3-8: Vegetative growth - Weeks 8-10: Heading (seed head emergence) - Weeks 10-14: Grain fill - Weeks 14-16: Harvest
Characteristics: - Sorghum grows slowly at first, then rapidly - Heat-loving (thrives when corn is stressed) - Drought-tolerant once established - Deep root system
Fertility
Sorghum is efficient:
- Nitrogen: Moderate needs. Less than corn. If following legumes, you're set.
- Phosphorus: Important for root development.
- Potassium: Adequate in clay soils.
- pH: 6.0-7.0 (tolerates slight acidity)
Organic Approach: - Add compost at planting - Sorghum is less demanding than corn - Drought-tolerant once established
Water Needs
Sorghum's superpower is drought tolerance:
- Establishment: Needs consistent moisture first 3-4 weeks
- After establishment: Deep roots access water
- Drought response: Goes dormant, resumes when water returns
- Total water needs: Less than corn
For West Virginia: Typical rainfall is sufficient. Irrigation only needed in extreme drought.
Processing Sorghum for Food
Grain Sorghum
Whole Grain: - Cook like rice (1:3 ratio, 45-60 minutes) - Use in pilafs, soups - Nutty flavor
Popping Sorghum: - Some varieties pop like popcorn - Heat in popcorn popper or skillet - Smaller than popcorn but fun
Flour: - Mill in grain mill - Gluten-free - Use for baking (often blended) - Pancakes, bread, cookies
Sorhum Flakes: - Steam whole grain - Roll flat - Dry - Use like oatmeal
Sweet Sorghum Syrup
Traditional Process: 1. Extract juice from stalks (crush in mill) 2. Strain juice 3. Boil down (hours of cooking) 4. Skim scum repeatedly 5. Reduce to syrup consistency 6. Bottle hot
Equipment Needed: - Cane mill (crushes stalks) - Large kettle (20+ gallons) - Heat source (propane, wood) - Skimming tools
Yield: - 10 gallons juice = 1 gallon syrup - Labor-intensive but rewarding
For The Loop Farmstead: Sorghum syrup is traditional Appalachian sweetener. If you have the equipment and want to preserve this tradition, grow sweet sorghum. Otherwise, grain sorghum is simpler.
Sorghum for Livestock
Grain: - Excellent feed for chickens, pigs, cattle - Similar nutritional value to corn - Can be 50%+ of ration - Gluten-free option
Forage: - Sorghum-sudangrass hybrids for hay - Cut and dry for hay - Warning: Young sorghum can contain prussic acid (toxic) - Don't graze until plants are 18" tall - Don't graze after frost (prussic acid increases)
Caution: - Fresh sorghum: Wait until plants are mature - After frost: Don't feed for 2 weeks (toxin breakdown) - Hay: Safe after proper drying
Sorghum Pests and Diseases
Common Issues:
Insects: - Sorghum midge: Damages seed heads - Prevention: Early planting, resistant varieties - Aphids: Sugarcane aphid is serious - Control: Beneficial insects, neem oil - Worms: Armyworms, corn earworm - Control: Bt, hand-picking
Diseases: - Leaf blight: Fungal - Prevention: Resistant varieties, rotation - Head smut: Fungal - Prevention: Resistant varieties, clean seed
Birds: - Major problem: Birds love sorghum - Solutions: Netting, scare devices, early harvest
Organic Management: - Choose resistant varieties - Rotate crops - Encourage beneficials - Net for birds if needed
Final Thoughts
Sorghum is the grain for hot, dry times. It's drought-tolerant, productive, and versatile. For West Virginia clay, sorghum is a smart addition to your grain strategy.
Grow sorghum for flour, for feed, for syrup. Learn its rhythms. Appreciate its resilience.
