Fall Cover Crops & Their Importance

Fall is actually one of the best times for backyard gardeners to work on improving their soil health. Without a lot of effort gardeners can improve the soils through the fall, winter, and early spring for a better gardening season next year through the use of cover crops. Cover crops are not just for large farms and have a variety of benefits.

Benefits

Reduce Erosion

First off, using a winter cover crop is extremely important in resducing erosion. When there’s nothing growing in the soil in fall, winter, and early spring any rain or melt water can erode valuable soil and nutrients and pollute the local water system. Too many nutrients in the lakes, streams, and river can cause algae blooms that can be dangerous to both people and aquatic life.

Add Organic Matter

As cover crops die or are tilled into the soil they add organic matter which is key to soil health! It gives the soil structure, retains moisture, provides habitat and food for beneficial insects and microbes, and adds nutrients to the soil as it slowly breaks down. If not tilled in the pant material also functions as a mulch to continue to suppress weeds, preserve moisture, and reduce ersosion.

Conserve Moisture

In the same way that open soil is vunerable to ersion it’s also vunerable to evaporation.  Cover crops prevent sun and wind from drying out the soil and hold rainwater.

Some Fix Nitrogen

Any cover crop variety that is a legume actually adds nitrogen to the soil as it grows in addition to the nutrients it provides when it dies or is tilled under. Some examples SESE carries will be given below.

Suppress Weeds

Cover crops also help to suppress weeds. Most cover crops are quick growing and vigorous allowing them to outcompete and knock back weeds.

Help Pollinators

Often your fall cover crops will be one of the first plants blooming in the spring, a critical time for pollinators. Planting in the fall gives you and them a jump start. They’re provided a reliable food source early helping you ensure reliable pollination throughout the growing season.

Fall Cover Crop Varieties

Southern Exposure offers a variety of cover crops suitable for fall planting.

Hairy Vetch

Hairy Vetch is both beautiful and useful. Bees and other pollinators love its purple flowers. It’s also a nitrogen fixing legume. Sow August 1st – November 1st.

Austrian Winter Peas

This awesome crop can be grown through the winter in zones 6 and up. It’s nitrogen fixing and edible! Sow August 15th – November 1st.

Buckwheat

Buckwheat isn’t really a winter cover crop becuase it’s what is called a “winter-kill crop” meaning that it dies back with the fall frosts. However it’s great for planting in the fall with a mix of clover because it provides clover shade and cool soil until it dies allowing th clover to take off. It can be planted in the spring up until 1 month before the last fall frost.

Crimson Clover

This nitrogen fixer does best where winter temperatures don’t dip below 10°F. It has longer blooms than traditional red clover. Sow from mid-July through mid-September.

Red Clover

Red clover has a lot going for it. It’s well loved by pollinators, fixes nitrogen, is great for weed supression and makes a wonderful, medicinal tea. Sow in spring or fall.

White Dutch Clover

Like the other clovers White Dutch is excellent for nitrogen and supressing weeds. Sow in late winter, spring, late summer, or fall.

Hulless Oats

Hulless Oats make an excellent cover crop for adding a lot of organic material. It should be noted that they will winter kill in areas where the temperature drop below 10°F. Oatstraw stems can be harvested for tea. Sow in later summer for a winter cover crop.

Common Winter Rye

While Winter Rye is not nitrogen fixing it’s still an excellent cover crop. It can actually help stabilize excess nitrogen and releases phosphorus and potassium from the soil for plants to use. It’s extensive root system makes it excellent for improving soil structure. It’s also vigorous and great for weed supression, erosion reduction, moisture conservation, and adds tons of organic material to the soil. Sow August 1st – November 15th.

Just because the gardening season is coming to a close doesn’t mean there’s not still planting to be done. If you want a healthy productive garden next year it’s definitely worth the effort to plant a cover crop this fall!

Seed Saving for Beginners

Saving seed and heirloom varieties is extremely important work, whether on a large scale like at Southern Exposure or a smaller scale like a family’s backyard garden. Saving seed helps to preserve genetic diversity, provide people with secure food sources, and connect people to the earth and their local community.If You want to buy some seed in America, I recommend you to visit most trust worthy site  best American seed banks.

Unfortunately saving seeds isn’t as simple as harvesting and cleaning your seeds. First you need to ensure you have the right kind of plants to start with.

Open Pollinated vs. Hybrid

In order to save seed that will “breed true” or have the same characteristics as its parents you need to start with open pollinated or heirloom seeds or plants. All heirlooms are open pollinated but not all open pollinated plants are heirlooms.

Open Pollinated

Open pollinated simply means that a variety has been bred and then maintained until it was genetically stable. This means that if you save seed from an open pollinated individual that seed will grow plants with the same characteristics as its parent plants.

Heirlooms

Heirlooms are just open pollinated varieties that have been passed down for many generations. While there are a few definitions, at SESE we describe heirlooms as varieties dating from before 1940. Unlike modern varieties that have been developed for use with modern industrial agriculture and our global food system these varieites were grown, saved, and cherished by small farmers and gardeners.

Hybrids

Hybrids on the other hand are not genetically stable. They are the seed from two seperate varieites being crossed. While their first generation traits are predictable they would not be if you were to again save seed. The second generation seed can have characteristics from one or both of the parents or entirely new characteristics altogether.

Hyrbrids are not GMO or inherently bad. In fact many people grow them for their “hybrid vigor” which can make them grow faster than their open pollinated counter parts.

Choosing a Variety

Obviously you’ll want to choose a variety you love and care about. Maybe you fell in love with an heirlooms story or your family just can’t eat enough of your a certain variety. Whatever the case, it’s much easier to stay motivated throughout the season and proccess if you’re really invested.

If you’re a first time seed saver you may also want to consider choosing from a few easy vegetables. Squash, cucumbers, beans, peas, tomatoes, and peppers are all great choices for beginners.

Planting

If you want to grow plants to save seed there’s a couple things you need to consider. First many plants require other plants of the same variety to pollinate with and produce viable seed. Also for this reason seperate varieties should be kept a certain distance apart to avoid cross pollination. For more about how to plan a seed saving garden check out this post:

Garden Planning for Seed Saving

Selection

Even if you don’t have longterm goals for changing or creating a new variety selecting which seed to save is still important. You want to save seeds from healthy and productive plants that have desirable traits.

Harvesting the Seed

Tomatoes

Old German Tomato

To save seed from tomatoes you should harvest them when they’re fully ripe. Then the flesh can be seperated from the seeds and gel that surrounds them. The gel and seeds should be placed in a glass container with a bit of water and lightly covered. This mixture should be stirred twice a day unil the seeds sink to the bottom. The liquid can then be poured off and the seeds rinsed and spread on a towel to dry.

Peppers

Cayenne, Long Red Hot Pepper

Peppers are much easier to save seed from than tomatoes because their seeds lack that gelatinous coating. Wait until the pepper is over ripe, it should begin to wrinkle, and then harvest the seeds and spread them out to dry.

Cucumbers

Mexican Sour Gherkin (Mouse Melon, Sandita)

A ripe cucumber for eating is not the same as a ripe cucumber for seed saving. Cucumbers you wish to save seed form should be allowed to ripen on the vine until they’re yellow or brown in color. Then they need to cure for an additional two weeks or until mold begins to appear. Then the seeds can be scooped out and fermented in a jar just like tomato seeds.

Peas & Beans

Creel Crowder Southern Pea (Cowpea)

Harvest your peas and beans when the pods have turned brown. Then dry them in a single layer for 1-2 weeks until they’re crisp and dry enough that you can here the seeds rattle in the pods. They can be threshed individually or stomped or beaten in a pillow case to remove the pods and then winnowed.

Squash

Candy Roaster Melon Winter Squash

Winter squash, summer squash, and pumpkins are all harvested in the same method. Wait until the fruit is hard and large to harvest. Then cure for 1 month at room temperature before removing the seeds. Wash seeds thoroughly and lay out in a single layer to dry for 3 weeks.

Storage

All seeds should be stored in air tight containers in a cool dry place. Some people choose to add a small amount of silica desiccant in with their seeds to absorb moisture. It’s also important to note that different types of seeds have different lifespans.

 

Saving seed really isn’t difficult. It’s a great way to connect with land and a bit of history. Start saving seeds this season or making a plan for next year’s garden! For more information check our Seed Saving Guides in our Growing Guides Library.

Super Easy Fresh Tomato Salsa & Tomato Tastings!

When we have all the ingredients to make garden fresh salsa I know that summer is finally in full swing. The garden has started overflowing with squash, peppers, garlic, beans, and my absolute favorite tomatoes!

This quick fresh salsa is one of my favorite summer dishes. It looks fancy, tastes, great, and comes together in minutes. Making it perfect to throw together for lunch after working in the field or making to share at a family barbeque.

This recipe is also one of those that you can play with a lot.

Here’s what you’ll need:

2-3 good sized tomatoes (mine weighed about 1 1/2lbs)

2 sweet banana peppers (or 1/2 a sweet bell pepper)

1/2 small onion

1 jalapeño pepper

1 clove of garlic

1/2 TBS lemon/lime juice

Cilantro to taste (if dried I use about 3/4 tsp and a small handful if fresh)

Salt & pepper to taste

There’s a few points to note when selecting ingredients. The tomatoes, in my humble opinion, are absolutely what make this recipe. Use homegrown or from a local farmer, storebought tomatoes just aren’t worth it. Paste tomatoes will make for a less watery salsa but I just go with whatever I have on  hand. I adore the look of salsa made with different color heirlooms.

You can also vary the peppers. I like a mix of sweet and hot peppers. The sweet bananas are super easy to grow and I find that 1 jalapeño adds a lot of flavor with out being overwhelmingly spicy but if you like it hotter or grow other types of peppers, go for it! Just try adding a little at a time.

I’ve used both yellow and purple onions and am happy with both but many people find they prefer purple onions for salsa. The cilantro and garlic can also be varied to taste. Fresh is better but in a pinch you can use dried cilantro and garlic powder.

To prepare:

Begin by dicing the tomatoes, peppers, onion, and cilantro. I like mine chunky but you can dice your ingredients as small or large as desired. For a smoother salsa pulse all the ingredients in a food proccessor until the desired consistency is reached.

Mince and add the garlic clove and stir in the lemon juice and salt and pepper to taste. It’s so good you may eat it all with just a bag of tortilla chips but it’s also excellent with tacos.

Don’t stop reading tomato fans!

If you’re as fanatical about homegrown tomatoes as I am be sure to stop in and visit Southern Exposure at two upcoming tomato tasting events!
