8 Reasons to Grow Austrian Winter Peas

We’ve mentioned fall cover crops a lot on this blog. They help protect your soil through the winter, preventing erosion and providing habitat for beneficial insects and fungi. They also add nutrients and organic matter, and suppress weeds. One of our favorite fall cover crops is Austrian winter peas. Here’s why you should consider adding them to your garden:

1. It’s not too late to plant Austrian winter peas!

At least in the upper south, the end of October is a bit late to be sowing most cover crops. Thankfully, these peas will tolerate temperatures down as low as 0°F for brief periods. We still recommend planting them 4 to 6 weeks before your first hard frost for best results. However, we’ve had luck planting later than that. You can also improve their cold tolerance by sowing them with winter rye which will help shelter the peas from wind and cold temperatures. 

2. The flowers are beautiful and edible.

It’s hard not to fall in love with those little bi-colored blossoms. Beyond adding beauty to your springtime garden, you can use them to add color to salads or be as natural decorations for baked goods. 

3. They’re nitrogen-fixers.

Not all cover crops have the same benefits. Austrian winter peas are what are commonly known as nitrogen fixers, meaning that they have a symbiotic relationship with specific bacteria. The bacteria colonize the plant’s roots and pull nitrogen out of the atmosphere. The bacteria use the nitrogen, and then it becomes available to the plant.

When you plant Austrian winter peas as a cover crop, that nitrogen is added to the soil for your next crop to use. Additionally, the peas provide habitat for the same type of bacteria that other legumes like snap peas and pole beans use. Helping these beneficial bacteria flourish in your soil will give you better results with these sorts of crops.

4. The shoots are great in salads and stir-fries. 

Austrian winter peas are primarily grown as a cover crop or green manure, but they’re also a tasty green. The young shoots can be snipped off and added to salads and stir-fries. They have a nice pea-like flavor and will continue to grow in much of the south through the winter.

5. Austrian winter peas make great mulch. 

When you’re ready to plant other crops in spring, you have a couple of options when cover cropping with winter peas. Often, people choose to till them in. However, you can also use them in a no-till garden. Simply scythe them down (or cut or pull them by hand for small beds) and plant directly into them. They make a excellent layer of mulch and will slowly decay and add organic matter to the soil.

6. Livestock loves Austrian winter peas too.

Humans aren’t the only ones that find Austrian winter pea shoots tasty. Livestock loves them. During the winter, you can cut some as a treat for goats, chickens, or other backyard livestock.

7. You can eat them like snap peas.

If you decide to let your Austrian winter peas continue growing in spring, you can eat the young pods as snap peas or use them like shell peas as they mature. Generally, they aren’t quite as sweet as other varieties. 

8. The flowers are helpful for pollinators. 

When you fall plant Austrian winter peas, they get ahead start on many of your spring garden crops. This means they flower early, providing bees and other pollinators with food at a critical time.

We grow and offer many different cover crops at SESE, but Austrian winter peas have earned a place as a fall favorite. They’re a great dual-purpose crop for small farmers and gardeners looking to improve their soil health and grow fresh food during the winter.

Great Beans & Peas: Using Legume Inoculant

If you’ve been gardening for a while, you’ve probably heard that beans, peas, and other legumes are nitrogen-fixing, meaning that they add nitrogen to the soil as they grow. However, many gardeners are less aware of exactly how this process works.

This process is a symbiotic relationship between legumes and specific types of bacteria called Rhizobacteria. These bacteria cause legumes to grow nodules on their roots. The bacteria live on the nodules and get carbohydrates from the plants. In return, the bacteria take nitrogen from the air and convert it to a form that is accessible to the plants.

Why do I need to inoculate? Doesn’t this bacteria occur naturally?

Rhizobacteria do occur naturally in some soil. However, there may be little to none present, particularly if you haven’t grown legumes in that area for several years. Legumes perform better with more bacteria present.

If you’ve ever had legumes fail to thrive, a lack of rhizobacteria may be part of the problem. Adding inoculant will ensure that there’s enough present to perform nitrogen fixation.

Using legume inoculant can:

  • Improve vigor and health of legume plants.
  • Improve yields.
  • Increase nitrogen available for other plants.

How do I inoculate my legumes?

Inoculating legume seeds is very simple. All you need to do is moisten your seeds and dust them with a bit of inoculant. You should plant them within 24 hours of inoculating.

We provide full instructions as well as more information on the Guard-N Inoculant we carry here.

The inoculant mix we carry at SESE contains Bradyrhizobium sp. (Vigna), Rhizobium leguminosarum biovar viceae, Rhizobium leguminosarum biovar phaseoli, and Bradyrhizobium japonicum. It can be used with:

  • Garden peas, including shelling, snap, and snow peas
  • Sweet peas
  • Lima beans
  • Soybeans
  • Fava beans
  • Southern peas
  • Asparagus beans
  • Common beans such as snap beans
  • Peanuts
  • Sunn hemp
  • Vetch (Vicia sp.) including Hairy Vetch, but not Crown Vetch.

What’s a Nitrogen Fixer?

Nitrogen fixing plants have a symbiotic relationship with specific bacteria. The bacteria colonize the plant’s roots and pull nitrogen out of the atmosphere. The bacteria uses the nitrogen and then it becomes available to the plant.

Nitrogen fixing plants include most plants in the legume family. They also include certain grasses like buckwheat but legumes are generally the most efficient. 

Why are they important?

Nitrogen is key for plant growth. Plants require it in order to perform photosynthesis. Yellow or pale leaves can be a sign that your soil lacks sufficient nitrogen. Rotating nitrogen-fixing crops through your garden replenishes nutrients in the soil without resorting to using synthetic fertilizers. 

Many nitrogen fixing crops, like those listed below, are used as cover crops or green manures. Like other cover crops they help prevent moisture loss, reduce erosion, and provide habitat for beneficial insects and fungi all while adding nitrogen to the soil. Using cover crops is in investment in soil health.

Nitrogen Fixing Cover Crops

Other legume crops like beans and peas are also nitrogen fixing. Pole beans are grown in the “Three Sisters” garden technique because they help provide nitrogen for the heavy-feeding corn.

Growing Cover Crops

Nitrogen fixing cover crops can be used in different ways. Biennial or perennial crops like clover are often grown for a season or year and then tillled under. This process adds organic matter to the soil and makes the plants’ nitrogen and other nutrients available to your crops. Alternatively winter-kill or annual crops like Sunn Hemp die back on their own and can be used as mulch. As they decompose they add nutrients and organic matter to the soil. 

These nitrogen fixing crops are also perfect for permanent pathways between rows or beds. Clover pathways in particular can be mowed through the summer. The clippings make excellent mulch for the adjacent beds.
