How to Grow Wisconsin SMG Wheat
Wisconsin SMG Wheat
Triticum aestivum
grassWisconsin SMG (Soft Milling Grade) wheat is a winter wheat variety developed at the University of Wisconsin, specifically bred for soft winter wheat production in the Upper Midwest. This variety is known for its excellent milling and baking qualities, making it ideal for commercial grain production. It combines good disease resistance with reliable yields in challenging northern climates.

Fall Germination & Establishment
6-8 weeksSeeds germinate in autumn and develop a strong root system and tillering before winter dormancy. Young shoots are 2-4 inches tall when growth slows in cold months.
Plant in late September to mid-October in Wisconsin. Ensure good soil contact. Avoid planting too early (disease risk) or too late (insufficient winter hardiness). Keep field weed-free during establishment.
Winter Dormancy & Spring Green-Up
3-4 months (December-April in Wisconsin)Plant remains relatively dormant under snow cover. Growth resumes in early spring as temperatures warm and soil thaws, with rapid tiller development.
Provide winter protection through adequate snow cover or mulch in marginal areas. Monitor for winter damage (winterkill). Apply spring nitrogen fertilizer (split applications) as growth begins.
Vegetative Growth & Tillering
4-6 weeks (April-May)Rapid leaf and shoot development with multiple tillers forming from the base plant. Plants grow 8-18 inches tall with 4-6 green leaves visible.
Continue nitrogen applications if needed (split applications reduce disease). Monitor for Hessian flies and armyworms. Ensure adequate soil moisture during spring rains. Control weeds before they compete.
Stem Elongation & Heading
3-4 weeks (May-June)Rapid stem growth with internodes elongating. Head emerges from boot (sheath) and begins to develop florets. Plants 20-36 inches tall with visible spike development.
Monitor for fungal diseases (leaf rust, stripe mosaic) common during heading. Ensure adequate potassium and phosphorus. Reduce nitrogen application to avoid excessive lodging. Scout for pest activity.
Flowering, Grain Filling & Maturation
4-5 weeks (June-July)Florets flower and are pollinated. Grain develops and fills with starch and protein. Head hardens and color changes from green to golden. Moisture content decreases from 40% to 12-14%.
Avoid overhead irrigation during flowering (disease risk). Monitor grain development; squeeze kernels to check hardness. Watch for combine-ready stage when kernel moisture reaches 12-14%. Begin harvest when plants are golden and kernels are hard (cut in half with fingernail difficulty).

Common Pests
-
Plant resistant varieties like SMG; use cultural practices (crop rotation, fall plowing); plant dates that avoid peak fly emergence; resistant cultivars strongly recommended
-
Scout plants in spring; apply insecticides if threshold exceeded; cultural controls (tillage, rotation); use resistant varieties when available
-
Plant resistant varieties; use clean seed; destroy volunteer wheat; reduce herbicide use (stress tolerance); rotate crops
-
Monitor for wheat dwarf virus vectors; spray insecticides if populations exceed threshold; encourage natural predators; remove infected plants
-
Plant resistant varieties; ensure good air circulation; apply fungicides if necessary; avoid excessive nitrogen; practice crop rotation
-
Resistant varieties are most effective; fungicide applications during heading; sanitation (remove debris); crop rotation to non-host crops
-
Plant virus-resistant varieties like SMG; control aphid vectors with insecticides; remove infected plants promptly; rogue volunteer wheat
Uses
Milling & Baking
CulinaryWisconsin SMG wheat is a soft wheat specifically bred for superior milling and baking qualities. It produces fine-textured flour ideal for cakes, pastries, cookies, and quick breads. [source]
Commercial Grain Product
CulinaryWidely used by commercial mills and bakeries throughout the Upper Midwest. The soft grain structure allows for efficient milling and produces flour with desirable protein and starch balance. [source]
Home Flour Milling
HouseholdHome grain growers can mill SMG wheat berries into fresh flour for superior flavor and nutrition compared to stored commercial flour. The soft structure makes it easier to mill at home. [source]
Cover Crop & Wildlife Food
WildlifeWinter wheat provides erosion control, winter cover, and food for overwintering wildlife including game birds. It can be incorporated as a green manure crop. [source]
Straw for Craft & Livestock
CraftThe straw byproduct is valuable for crafts (basket weaving, straw art), livestock bedding, and garden mulch. SMG wheat produces sturdy, long-fiber straw. [source]
Harvest Tips
Harvest when grain moisture reaches 12-14% and kernels are hard (difficult to dent with fingernail). In Wisconsin, this typically occurs in late July to early August. Use a combine harvester for efficient grain collection. Cut at 4-6 inches height to minimize chaff. Thresh to separate grain from chaff. Clean and store grain at <12% moisture in cool, dry conditions. Yields typically range from 40-60 bushels per acre in Wisconsin conditions.
Fun Facts
- 🌱 Wisconsin SMG wheat was developed by the University of Wisconsin breeding program to thrive specifically in Upper Midwest conditions, addressing the need for soft winter wheat varieties suited to shorter growing seasons and colder winters.
- 🌱 Winter wheat is called 'winter' wheat because it requires a cold winter period (vernalization) to flower and produce grain; without this cold exposure, it won't head properly.
- 🌱 A single wheat plant can tiller (branch) into 5-10+ separate shoots, with each shoot potentially developing its own seed head, allowing one seed to produce hundreds of grains.
