layout: base.njk title: Buckwheat description: Growing Buckwheat in West Virginia (Zone 6b/7a) category: grain


Quick Reference: See detailed growing information below

For: The Loop Farmstead, New Martinsville WV 26155
Zone: 6b/7a
Soil: Heavy clay

Understanding Buckwheat

What Buckwheat Is (and Isn't)

Buckwheat is: - A broadleaf plant (not a grass) - Related to rhubarb, docks, sorrels (Polygonaceae family) - Gluten-free (safe for celiac sufferers) - A pseudocereal (used like a grain, botanically a seed)

Buckwheat is not: - A true cereal grain (not related to wheat, corn, oats) - Related to grasses - Cold-hardy (kills at first frost)

Spring/Summer Crop

Buckwheat is frost-tender: - Plant: Late spring to mid-summer (May-July) - Harvest: 70-90 days later - Multiple plantings possible in one season - Cannot overwinter

For West Virginia: - First planting: Late May (after all frost danger) - Second planting: Mid-June - Third planting: Late July (harvest before frost) - Cover crop planting: Anytime May-August

2. Mancan

Type: Improved Buckwheat
Days to Maturity: 75-85 days
Source: Baker Creek Heirloom Seeds, specialty suppliers
Characteristics: Higher yield than common, larger seeds, white flowers
Uses: Grain production, flour

Why Grow It: Mancan was bred for improved yield and larger seed size. It's a step up from common buckwheat for grain production. The plants are vigorous and productive.

Clay Soil Performance: Very good.

For The Loop Farmstead: If you're growing buckwheat primarily for grain, Mancan is worth seeking out.

4. Manhattan

Type: Modern Buckwheat
Days to Maturity: 70-80 days (early)
Source: Some regional suppliers, farm supply
Characteristics: Early maturity, good yield, uniform
Uses: Grain, cover crop

Why Grow It: Manhattan is a modern variety bred for earliness and uniformity. At 70-80 days, it's one of the earliest buckwheats. This matters in Zone 6b—you can plant later and still harvest before frost.

Clay Soil Performance: Good.

Growing Buckwheat on Clay Soil

Site Preparation

Buckwheat needs minimal preparation—it's famously low-maintenance.

Timing: - Plant: Late May through July - Soil temp: 65°F+ (buckwheat needs warm soil) - After last frost (buckwheat is frost-tender)

Preparation: 1. Clear previous crop residue 2. Lightly till or rake (buckwheat establishes in rough seedbeds) 3. Optional: Add compost (buckwheat will grow without it)

Buckwheat's Advantage: Buckwheat germinates in poor, unprepared soil. It's the crop you plant when you're tired and the seedbed isn't perfect. It grows anyway.

Planting

Seed Rate:

For Grain: - 45-60 lbs per acre (1-1.5 lbs per 1000 sq ft) - Small scale: 2-3 oz per 100 sq ft

For Cover Crop: - 60-90 lbs per acre (1.5-2 lbs per 1000 sq ft) - Small scale: 3-4 oz per 100 sq ft (higher rate for weed suppression)

For Green Manure: - 90-120 lbs per acre (2-3 lbs per 1000 sq ft) - Highest rate for maximum biomass

Method:

Broadcast (small scale): 1. Scatter seed evenly 2. Lightly rake to cover (1/2-1" deep) 3. Firm soil (walk over it) 4. Water if dry

Drill: 1. Plant 1/2-1" deep 2. Rows 6-8" apart

Clay-Specific Notes: - Buckwheat handles clay better than most crops - Roots penetrate and break up compaction - Don't plant in standing water - Otherwise, buckwheat is forgiving

Growing Season

Timeline: - May-July: Planting (successive plantings possible) - Weeks 1-2: Germination, seedling stage - Weeks 3-5: Rapid vegetative growth - Weeks 5-6: Flowering (white/pink flowers) - Weeks 7-10: Seed set, maturation - Weeks 10-13: Harvest

Flowering: Buckwheat flowers profusely for 2-3 weeks. The flowers are: - White to pink - Highly fragrant - Bee magnets (honey bees, native bees) - Beneficial insect attractors (hoverflies, parasitic wasps, predatory beetles)

For pollination: Plant buckwheat near gardens. It brings in pollinators that service your vegetables.

Fertility

Buckwheat is extremely low-maintenance:

  • Nitrogen: Buckwheat needs little nitrogen. Too much = lush growth, poor seed set.
  • Phosphorus: Buckwheat excels at scavenging phosphorus. It accesses P that other plants can't reach, making it available for subsequent crops.
  • Potassium: Moderate needs.
  • pH: Tolerates 5.0-7.0 (adaptable)

Organic Approach: - No fertilizer needed for cover crop use - For grain: Light compost is sufficient - Don't over-fertilize (reduces seed set) - Buckwheat grows in poor soil

Buckwheat as Cover Crop

Buckwheat is an outstanding cover crop:

Benefits: - Fast biomass: 60-90 days to significant growth - Weed suppression: Dense canopy shades out weeds - Pollinator support: Best pollinator plant available - Phosphorus scavenging: Makes P available for next crop - Clay breaking: Roots penetrate compaction - Easy termination: Winter-kills, or cut/flail easily - Short season: Fits between other crops

Use Cases:

Summer Smother Crop: - Plant after early harvest (June) - Grows through summer - Suppresses weeds - Terminate in fall

Between Crops: - After spring vegetables → buckwheat → fall vegetables - 70-90 day window fits perfectly

Pollinator Habitat: - Plant blocks near gardens - Flowering supports bees - Increases vegetable yields

Green Manure: - Grow 60-90 days - Cut and incorporate (or leave as mulch) - Plant next crop into residue

Clay Improvement: - Plant buckwheat in compacted areas - Roots break up clay - Terminate, plant deep-rooted crops next

Processing Buckwheat for Food

Cleaning

After threshing: 1. Winnow to remove chaff 2. Optional: screen to remove small debris 3. Store in airtight containers

Groats (Hulled Buckwheat)

Whole groats are hulled buckwheat seeds:

Dehulling: - Use grain mill with dehulling attachment - Or: lightly toast, run through food processor, winnow - Hulls are thin but require removal for most uses

Uses: - Cook like rice (pilaf) - Add to soups - Breakfast porridge

Kasha (Roasted Groats)

Kasha is roasted buckwheat groats:

To Make Kasha: 1. Hull buckwheat (see above) 2. Toast in dry skillet (medium heat, 5-10 minutes) 3. Stir constantly until fragrant and browned 4. Cook like rice (1:2 ratio, 15-20 minutes)

Traditional Uses: - Eastern European kasha (side dish) - Kasha varnishkes (kasha with bow-tie pasta) - Breakfast porridge

Buckwheat Flour

Milling: 1. Hull buckwheat 2. Mill in grain mill or blender 3. Sift if desired (whole grain flour includes bran)

Characteristics: - Dark color (gray-brown) - Distinctive flavor (earthy, slightly bitter) - Gluten-free - Best blended with other flours (25-50%)

Uses: - Pancakes (classic use) - Soba noodles (Japanese buckwheat noodles) - Bread (blended with wheat) - Muffins, quick breads

Storage: Buckwheat flour goes rancid quickly (high oil content). Store in refrigerator or freezer. Use within 3-6 months.

Cooking Buckwheat

Basic Groat Pilaf: - 1 cup groats - 2 cups water or broth - Salt to taste - Simmer 15-20 minutes - Fluff with fork

Buckwheat Pancakes: - 1 cup buckwheat flour - 1 cup wheat flour (or all buckwheat for GF) - 2 eggs - 2 cups milk - 2 tbsp oil - 1 tbsp honey - Cook on griddle

Soba Noodles: Traditional Japanese noodles made from buckwheat flour. Requires skill to make (buckwheat doesn't bind well). Buy dried soba or learn the technique.

Buckwheat for Livestock

Caution: Buckwheat can cause photosensitivity (fagopyrism) in light-skinned animals when fed in large quantities as fresh forage.

Grain: - Safe in moderation - Feed as portion of ration (20% max) - Excellent for chickens, pigs

Forage: - Limit fresh buckwheat grazing - Better as hay (sunlight exposure reduces risk) - Don't graze light-skinned animals (white pigs, sheep) on flowering buckwheat

Bottom Line: Buckwheat grain is fine for animals. Fresh forage requires caution.

Buckwheat Pests and Diseases

Buckwheat is remarkably pest-free:

Diseases: - Rarely affected by serious diseases - Occasional leaf spots (cosmetic) - Good air circulation prevents issues

Insects: - Aphids: Occasional, rarely serious - Beneficials attracted TO buckwheat outweigh pests

Advantage: Buckwheat's short season means it escapes many pest cycles.

Organic Management: - Rarely needs intervention - Rotate crops - Maintain diversity

The Phosphorus Mobilizer

Buckwheat has a unique ability: it accesses phosphorus other plants can't reach.

How It Works: - Buckwheat roots exude organic acids - These acids dissolve locked-up phosphorus in soil - Buckwheat takes up the phosphorus - When buckwheat decomposes, phosphorus becomes available to next crop

For West Virginia Clay: Clay soils often have adequate total phosphorus, but it's "locked up" and unavailable. Buckwheat unlocks it. Following buckwheat with phosphorus-hungry crops (corn, squash) yields better results.
