How to Plant Austrian Winter Peas: The Ultimate Guide for a Thriving Cover Crop
Are you looking for an easy-to-grow cover crop that improves soil health, fixes nitrogen, and provides food for wildlife? If so, Austrian winter peas might be the perfect choice for your farm or garden.
Austrian winter peas, scientifically known as Pisum sativum subsp. arvense, are a cold-hardy nitrogen-fixing legume that works wonders as a green manure crop. They help prevent soil erosion, improve soil structure, and serve as an excellent winter forage for livestock and deer. Their ability to fix nitrogen into the soil reduces the need for synthetic fertilizers, making them a cost-effective and environmentally friendly option for improving soil fertility.
Planting Austrian winter peas is not just about improving your soil; it also provides an excellent opportunity to support biodiversity. These peas are known to attract beneficial insects such as bees and ladybugs while simultaneously deterring harmful pests. Additionally, they serve as a vital winter food source for deer and other wildlife, making them a favorite among hunters who maintain food plots.
With all these benefits in mind, let’s dive into the best practices for planting Austrian winter peas successfully.
Benefits of Planting Austrian Winter Peas
Before we get into the planting process, let’s explore why these peas are a fantastic choice for your garden or farm.
Soil Health and Nitrogen Fixation
Austrian winter peas play a significant role in soil improvement. Like other leguminous cover crops, they work symbiotically with soil bacteria to fix atmospheric nitrogen, converting it into a form that plants can readily absorb. This natural fertilization process reduces the dependency on chemical fertilizers, leading to healthier and more sustainable farming practices. As they grow, their roots break up compacted soil, allowing for better water infiltration and root development for future crops.
Erosion Control and Weed Suppression
During the winter months, exposed soil is vulnerable to erosion caused by wind and rain. The dense growth habit of Austrian winter peas acts as a protective barrier, keeping topsoil intact and reducing nutrient loss. Additionally, their rapid growth and thick foliage prevent weeds from taking over, leading to a cleaner planting area for subsequent crops in the spring.
Forage for Livestock and Wildlife
If you are a farmer raising livestock, Austrian winter peas provide an excellent source of forage. Their high protein content makes them a valuable addition to the diets of cattle, sheep, and goats. Similarly, for those who manage deer food plots, these peas are highly palatable and nutritious, attracting wildlife throughout the winter and early spring.
Companion Planting Benefits
Austrian winter peas pair well with cereal rye, oats, and clover to create a diverse cover crop mix. This combination enhances soil health while providing multiple benefits such as weed suppression, improved soil aeration, and increased biodiversity in the garden.

When to Plant Austrian Winter Peas
Timing is crucial for a successful cover crop. Depending on your location and climate, here’s when you should plant Austrian winter peas:
Northern States (Zones 3-6): Plant in late summer to early fall (August to September) to establish before winter.
Southern States (Zones 7-10): Plant in fall through early winter (October to December) for optimal growth.
Early Spring Planting: If planting in early spring, make sure the soil is workable and not waterlogged to avoid root rot issues.
For the best results, monitor soil temperatures and ensure they remain above 40°F (4°C) for proper germination.
How to Prepare the Soil for Planting
Proper soil preparation ensures healthy seed germination and vigorous growth. Follow these steps:
Test Your Soil: Austrian winter peas thrive in well-drained soils with a pH of 6.0-7.0. Use a soil test kit to check pH and nutrient levels.
Clear the Area: Remove weeds, debris, and previous crops to give the peas a clean growing environment.
Loosen the Soil: Use a tiller or garden fork to break up compacted soil, ensuring good root penetration.
Incorporate Organic Matter: If the soil lacks fertility, mix in compost or aged manure for added nutrients.
Step-by-Step Guide to Planting Austrian Winter Peas
Choosing the Right Seeding Method
Austrian winter peas can be planted using two main methods:
Broadcast Seeding: Ideal for large areas and cover cropping. Simply spread seeds evenly across the field and lightly rake them into the soil.
Drilled Seeding: Best for row planting in deer food plots or smaller gardens. Use a seed drill or hand plant them in rows.
Seed Depth and Spacing
Depth: Plant seeds 1 to 2 inches deep to protect them from birds and frost.
Spacing: Sow seeds 2-3 inches apart, with rows spaced 6-12 inches apart.
Watering After Planting
Water the soil thoroughly after planting to encourage germination. Austrian winter peas prefer moist but well-drained soil. Avoid overwatering, as soggy soil can cause root rot.
Caring for Austrian Winter Peas
Watering Needs
While Austrian winter peas are drought-tolerant, providing consistent moisture during germination and early growth will boost establishment.
Weed Management
To suppress weeds naturally, interplant Austrian winter peas with cereal rye or mulch around the plants to retain soil moisture and block weed growth.
Pest and Disease Prevention
Common pests include aphids and pea weevils. Use neem oil or introduce beneficial insects like ladybugs for control. For diseases, ensure proper spacing to improve airflow and prevent fungal infections.
Harvesting and Using Austrian Winter Peas
For Green Manure: Mow or till the plants into the soil before flowering to maximize nitrogen release.
For Edible Shoots: Harvest young pea shoots and use them in salads for a nutritious boost.
For Forage: If grown as livestock feed or deer food plots, allow the plants to mature before grazing.
Common Mistakes to Avoid
Planting too late in the season, which affects establishment.
Overcrowding, leading to poor airflow and increased disease risk.
Ignoring soil pH, which can hinder growth if too acidic.
Conclusion
Planting Austrian winter peas is an easy and effective way to boost soil fertility, improve soil health, and support wildlife. Whether you are a farmer looking for a nitrogen-fixing legume or a gardener wanting a green manure crop, these hardy winter peas are a fantastic choice.
