Quick Reference: See detailed growing information below

For: The Loop Farmstead, the homestead 26155
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 Zone 6b/7a: 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

What We're Growing on The Loop Farmstead

Planted May 15, 2026 — Soil temp reached 65°F+ on our south-facing slope. Three varieties in the ground, one to follow.

Wheatland (Grain Sorghum)

Type: Grain Sorghum (Milo)
Purpose: Flour, animal feed, gluten-free grain
Days to Maturity: 100-110 days
Characteristics: Medium-tall plants, reliable grain producer, good for clay soils. Wheatland is a workhorse grain sorghum — not flashy, but dependable. Produces tight seed heads that resist bird damage better than loose-headed types.

Our plan: Primary grain sorghum for flour and feed. Mill into gluten-free flour, use whole in soups, feed surplus to chickens.

Honeydrip (Sweet Sorghum)

Type: Sweet Sorghum (Syrup Cane)
Purpose: Sorghum syrup, traditional Appalachian sweetener
Days to Maturity: 105-115 days
Characteristics: Tall stalks (8-10 feet), high sugar content in juice, excellent for syrup production. Honeydrip is bred for sweetness — the juice runs sweet like its name suggests.

Our plan: Syrup production. Press stalks in a cane mill, boil down to sorghum syrup. Traditional Appalachian sweetener that stores indefinitely. If we don't have a mill yet, stalks can be chewed fresh or chopped for animal feed.

Broom Corn

Type: Broom Corn (Sorghum bicolor var. technicum)
Purpose: Broom making, craft, decorative
Days to Maturity: 110-120 days
Characteristics: Long, fibrous seed heads (18-24 inches) on tall stalks (6-15 feet). Not grown for grain — grown for the tassel-like seed heads that make natural brooms. One of the oldest cultivated plants in human history. Also makes excellent bird feed (the small seeds) and can be used for crafts, wreaths, and dried arrangements.

Our plan: Make brooms. Real, functional brooms from our own land. Also decorative, also feed, also just because it's weird and wonderful and connects us to thousands of years of craft. Broom corn is permaculture in plant form — multiple yields from one planting.

Mennonite (Planting Later)

Type: Sweet Sorghum (Heritage Syrup Cane)
Purpose: Sorghum syrup, heritage variety preservation
Days to Maturity: 105-115 days
Characteristics: Heritage variety with deep Appalachian and Amish/Mennonite roots. Mennonite sorghum is a traditional syrup cane preserved by communities who never stopped making sorghum syrup. Rich, complex flavor — the kind of sweet that has history in it.

Status: Not yet planted. Going in when conditions are right — likely late May to early June. We'll update this page when it's in the ground.

Planting Notes — May 2026

Site: South-facing slope, the homestead (Zone 6b/7a)
Soil temp: 65°F+ as of May 15
Method: Direct seed, ½-1" deep, 4-6" between plants, 30-36" between rows
Strategy: Grain sorghum (Wheatland) + sweet sorghum (Honeydrip) + broom corn interplanted. Three yields from one field — flour, syrup, brooms. Mennonite goes in separately when ready.

Final Thoughts

Sorghum is the grain for hot, dry times. It's drought-tolerant, productive, and versatile. For local clay, sorghum is a smart addition to your grain strategy.

Grow sorghum for flour, for feed, for syrup. Learn its rhythms. Appreciate its resilience.
