Millet seed buying guide

Choose the Right Millet Seeds

Millet seeds are fast-growing warm-season annual grasses valued for green manure, cover cropping, forage, fodder, grain production and soil improvement. They establish rapidly in warm conditions, producing dense biomass that helps suppress weeds, reduce erosion and improve soil structure while protecting bare ground throughout summer.

Seedmart supplies carefully selected millet varieties for home gardeners, market gardeners, livestock producers, broadacre farming and regenerative agriculture throughout Australia. Whether you’re looking for a productive green manure crop, quality livestock forage, birdseed production or a fast summer cover crop, our range includes varieties suited to a wide range of growing conditions.

The best millet variety depends on your growing goals. French Millet is commonly grown for grain and birdseed, Japanese Millet is one of Australia’s most popular summer green manure and forage crops, while Shirohie Millet produces vigorous leafy growth for grazing and hay production.

Choosing the Right Millet Variety

Different millet varieties have been developed for different growing purposes. Some produce dense biomass for green manure and soil improvement, while others are better suited to forage, grazing, hay production or birdseed. Choosing the right variety will depend on how you intend to use the crop, your climate and the length of your growing season.

Growing Goal Recommended Variety Why Choose It?
Green manure and cover cropping Japanese Millet Produces abundant summer biomass, excellent ground cover and useful organic matter for improving soil health.
Fast weed suppression Japanese Millet Rapid establishment and vigorous growth help shade the soil and compete with weeds.

Soil improvement between crops Japanese Millet Fibrous roots improve soil structure while the leafy growth contributes valuable organic matter.
General-purpose summer crop Japanese Millet A versatile variety suitable for cover cropping, forage and soil improvement across much of Australia.

Tip: Millet is a grass rather than a legume, so it does not fix atmospheric nitrogen. For a balanced summer cover crop, many growers mix millet with warm-season legumes such as Sunn Hemp, Cowpea or Lablab.

Why Grow Millet?

Fast Establishment

Most millet varieties germinate quickly in warm soil and establish rapidly, making them excellent choices for summer cover cropping, forage production and short growing windows.

Excellent Biomass Production

Millet produces abundant leafy growth that can be incorporated into the soil as green manure or left as mulch to increase organic matter and improve soil structure.

Suppresses Weeds

Dense summer growth helps shade the soil surface, reducing weed competition and protecting bare ground between cropping cycles.

Quality Forage

Several millet varieties provide productive grazing, hay and silage options for livestock during the warmer months when managed correctly.

Protects Soil

The fibrous root system helps reduce erosion, improves soil structure and supports healthier soils by protecting exposed ground from heavy rain and summer heat.

Thrives in Warm Conditions

Millet performs best during spring and summer, making it an excellent choice for Australian growers looking for a productive warm-season crop.

Did you know? Millet grows much faster than many traditional pasture grasses and is commonly used as a short-term summer crop before vegetables, winter cereals or pasture renovation.

Common Uses for Millet

Millet is one of the most versatile warm-season crops grown in Australia. Different varieties are used for green manure, cover cropping, livestock forage, birdseed production and improving soil health. Whether you’re growing vegetables, managing livestock or establishing a regenerative farming system, millet can provide valuable benefits during the warmer months.

Green Manure

Japanese Millet is widely grown as a summer green manure crop. Its rapid growth produces abundant organic matter that can be incorporated into the soil or left as surface mulch to improve soil structure and protect against erosion.

Cover Cropping

Millet establishes quickly in warm soil, forming dense ground cover that helps suppress weeds, reduce moisture loss and protect bare soil between cropping cycles.

Livestock Forage

Shirohie Millet is commonly grown for grazing, hay and silage. It produces leafy, palatable forage that can provide valuable feed during the warmer months.

Birdseed Production

French Millet produces fine seed heads that are widely used in birdseed mixes and grain production, making it a popular choice for both commercial growers and hobby farmers.

Soil Improvement

Millet develops an extensive fibrous root system that helps improve soil structure, increase organic matter and support healthier soils when used in crop rotations.

Regenerative Agriculture

Millet is frequently included in regenerative farming systems because it produces large amounts of biomass, protects soil from erosion and complements nitrogen-fixing legumes in mixed cover crop plantings.

Many growers combine millet with warm-season legumes such as Sunn Hemp, Cowpea or Lablab. While millet contributes rapid biomass and ground cover, legumes help fix atmospheric nitrogen, creating a more balanced summer cover crop.

When to Sow Millet in Australia

Millet is a warm-season crop that performs best when sown into warm soil after the risk of frost has passed. Germination is rapid under favourable conditions, and the crop responds well to adequate moisture and full sun. Sowing times vary across Australia depending on climate and local temperatures.

Climate Zone Best Sowing Time Suitability Growing Notes
Cool Late Spring to Summer Moderate Sow only after frosts have finished and the soil has warmed.
Temperate Spring to Mid Summer Excellent Ideal as a fast-growing summer cover crop or forage crop.
Subtropical Spring to Early Autumn Excellent Warm temperatures and seasonal rainfall promote vigorous growth.
Tropical During the Warm Growing Season Excellent Produces abundant biomass where moisture and drainage are adequate.
Arid Spring to Summer with Irrigation or Rainfall Good Requires moisture during establishment for reliable growth.

Millet is frost sensitive. For the best results, wait until soil temperatures are consistently warm before sowing. Most millet varieties establish quickly once conditions become favourable.

General Millet Growing Guide

Millet is an easy crop to grow provided it is sown into warm soil with adequate moisture. Good seedbed preparation, correct sowing depth and timely management will produce vigorous growth for green manure, forage or grain production.

  1. Wait for warm soil.
    Millet is a warm-season crop and should only be sown after frost danger has passed and soil temperatures have warmed.
  2. Prepare a clean seedbed.
    Remove existing weeds and create a firm, level seedbed to improve seed-to-soil contact and encourage even germination.
  3. Sow at the recommended rate.
    Broadcast seed evenly or sow in rows using the sowing rate recommended for your intended use, whether green manure, forage or grain production.
  4. Cover the seed lightly.
    Millet seed should generally be covered with approximately 10–20 mm of soil. Avoid sowing too deeply as this may reduce establishment.
  5. Keep the soil moist during establishment.
    Adequate moisture is important during germination and early growth. Once established, millet tolerates short dry periods better than many other summer crops.
  6. Manage the crop for its intended purpose.
    For green manure, slash before seed heads mature. For forage, graze or cut while plants remain leafy. For grain or birdseed production, allow seed heads to fully mature before harvesting.
  7. Rotate with other crops.
    Millet fits well into vegetable gardens, orchards and farming systems where a fast summer crop is needed between main plantings.

Growing Tip: For maximum soil improvement, incorporate millet before seed heads mature while the stems remain green and succulent. This allows the plant material to break down more quickly and return valuable organic matter to the soil.
