How to Grow Oberkulmer Spelt Wheat

Oberkulmer Spelt Wheat

Oberkulmer Spelt Wheat

Triticum spelta subsp. spelta

grass

Oberkulmer Spelt is a heritage hulled wheat variety prized for its nutty flavor and nutritional profile. This ancient grain features distinctive spiked seed heads and golden-bronze coloring at maturity. It is well-suited for organic farming and home grain production.

Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily minimum; more sun improves grain development
💧
Water: Moderate water needs; requires consistent moisture during spring growth and grain filling. Typically 12-16 inches of rainfall annually is sufficient in temperate zones. Reduce water in late summer to promote ripening.
📏
Spacing: 4-6 inches between plants in rows; rows 6-8 inches apart for broadcast seeding at 1.5-2 bushels per acre inches
📅
Days to maturity: 150-180 days from planting to harvest-ready grain
🌱
Planting depth: 1-1.5 inches deep

Soil

Type: Well-draining loamy soil with moderate fertility
pH: 6.0-7.5
Amendments:
Compost or aged manure for organic matter Balanced fertilizer (moderate nitrogen) Lime if soil is acidic

Growth Stages

1

Germination & Emergence

2-3 weeks

Seeds germinate in 7-14 days with proper moisture. Seedlings emerge with narrow, pointed leaves characteristic of wheat.

Ensure adequate soil moisture but avoid waterlogging. Protect seedlings from frost if winter-planted. Thin seedlings if necessary to proper spacing.

2

Vegetative Growth (Tillering)

6-10 weeks

Plant produces multiple shoots (tillers) from the base, developing more leaves and establishing root system. Characteristic bluish-green coloring develops.

This stage benefits from moderate nitrogen fertilizer. Keep area weed-free through cultivation or hand-weeding. Ensure adequate moisture but avoid excess water that promotes disease.

3

Stem Elongation & Heading

4-6 weeks

Main stem bolts upward, leaves elongate, and the distinctive spiked head (spike) emerges from the leaf sheath.

Reduce nitrogen to avoid excessive vegetative growth. Monitor for pests and diseases. Ensure consistent water during grain filling stage that follows.

4

Flowering & Grain Filling

3-4 weeks

Spike flowers emerge (small and inconspicuous), and kernels begin to develop and fill with starch. Spike appears golden or bronze-tinted.

Critical moisture period; maintain consistent watering without waterlogging. Reduce pest and disease pressure by proper spacing and air circulation. Monitor for Hessian flies and Frit flies.

5

Ripening & Harvest Ready

2-3 weeks

Kernels harden and become darker; stalks turn golden-brown. Spike bends slightly with mature grain weight. Seeds reach full maturity and low moisture content (12-15%).

Cease watering 2-3 weeks before harvest to promote ripening. Allow stalks to fully dry in field. Harvest when grain is hard and cannot be easily dented with a fingernail.

Common Pests

  • Plant resistant varieties; time planting to avoid peak fly emergence; remove crop residue promptly; rotate fields annually

  • Early planting often avoids peak populations; maintain healthy soil; remove infested shoots if damage is minor

  • Monitor plants for feeding damage; handpick if populations are low; encourage natural predators; apply organic insecticides if threshold is exceeded

  • Cut and remove stubble; rotate crops; plant winter wheat varieties when possible; parasitic wasps provide natural control

  • Ensure proper spacing for air circulation; avoid excessive nitrogen; apply sulfur dust if necessary; select resistant cultivars

Uses

🍳

Whole grain flour for baking and pasta

Culinary

Oberkulmer Spelt flour produces distinctive nutty-flavored bread, pastries, and pasta with a slightly sweet undertone. The grain's natural adhesion of the hull adds fiber and nutritional complexity. [source]

🍳

Whole grain cereal and porridge

Culinary

Cooked spelt berries offer a chewy texture and rich flavor as a breakfast cereal or grain bowl base. Often preferred by those seeking ancient grains and heirloom varieties. [source]

💊

Nutritional support and digestibility claims

Medicinal

Spelt is valued for higher vitamin E, magnesium, and phosphorus content compared to common wheat. Some herbalists note that spelt's gluten structure differs slightly, though it still contains gluten and is unsuitable for celiac disease. [source]

🏠

Craft and decoration

Household

Dried spelt stalks and seed heads are popular in floral arrangements, wreaths, and dried grain displays for home décor. [source]

🦋

Wildlife food and habitat

Wildlife

Mature spelt plants provide seeds for songbirds and small mammals. The dense growth offers shelter for beneficial insects and ground-nesting birds. [source]

Harvest Tips

Harvest when grain is fully mature and hard (moisture content 12-15%), typically in mid to late summer. Cut stalks with a scythe, sickle, or small grain harvester; bundle and dry further for 1-2 weeks if needed. Thresh by hand, flail, or mechanical thresher to separate grain from chaff. Hulled spelt requires additional hulling equipment or mill processing to remove the adherent hull before use.

Fun Facts

  • 🌱 Oberkulmer Spelt is an heirloom Swiss variety with over 100 years of cultivation history, known for exceptional flavor and organic farming performance.
  • 🌱 Spelt's hulled kernel requires specialized milling and processing to remove the tough hull, making it less commercially viable than modern wheat but prized by specialty producers.
  • 🌱 In medieval Europe, spelt was a primary staple grain, especially in Central Europe, and remains culturally significant in Swiss, German, and Austrian cuisine.
