How to Build a Bean Tunnel

Pole beans are a treasured southern crop for many reasons. They have a lot of flavor, interesting history, and are easy to grow and productive. We’ve also found that they’re enjoyable to grow. We love making “bean tunnels” with pole beans. These bean tunnels make picking easy, create shady areas to rest in the garden, and make a great fort or play house for kids. Here’s the easy method we recommend for building and growing a DIY bean tunnel.

Supplies

You’ll need to round up a few supplies to build a bean tunnel. You’ll need some fence posts, strong but flexible fencing panels, and a fence post pounder or mallet to place your posts. Generally, we use green metal t-posts and cattle panels, but you may find other materials that are also suitable with a bit of work. Depending on what type of fencing and posts you’re using you may want some extra wire to help secure the panels to the posts.

Preparing Beds for a Bean Tunnel

You’ll want your bean tunnel set up so you can walk through it. Therefore you’ll need to create two beds with a walking pathway in between. These can be traditional or raised beds. 

Typically, the path in the middle should be about 5 feet wide. When the base of your tunnel is about this width, you’ll be able to create a sturdy yet fairly tall tunnel. 

You may find that closer to 6 feet or 4 feet works better for you but I would recommend experimenting with holding up your fencing to see what the arch will look like in place.

Once you’ve decided on their positioning, prepare the beds as you usually would for planting. You may want to loosen the soil with a broad fork or tiller and add a couple of inches of finished compost.

Setting Up Your Tunnels

As I mentioned in the previous section, you’ll probably want your posts placed so that the bottoms of the tunnel are about 5 feet apart. You need two posts per panel, with one on each side. To ensure you’re happy with this size, mark out your measurements and have two people hold the panel in place. If it looks good, you can go ahead and place your posts.

Once your posts are firmly in the ground, you’ll need two people to lift the panel and slide it over the poles. To begin, one person should hold their end roughly in position while the other slides their end over the post. Then the second person can slide their end over the post. If you feel like the panel isn’t secure you can use fencing wire to secure it to each post.

When built using t-posts and cattle panels, we’ve found that these trellises are plenty sturdy and hold up well to wind and weather.

Planting Your Tunnels

We use these trellises as bean tunnels, but you can grow various vining crops on them, including cucumbers, gourds, pole beans, winter squash, melons, or morning glories. Some folks also plant perennial vining crops like hops, roses, or grapes in this manner. Follow sowing or planting instructions for your chosen crop and plant them along the outsides of the tunnel.

The fruits of larger crops like melons and winter squash may need additional support. You can make little hammocks for them with scraps of old cloth or pantyhose.

That’s it! All you need to do is wait for the beans to grow and keep them watered or weeded. Before you know it, you’ll have a shady tunnel covered in bean leaves. Happy gardening!

Awesome Alliums: Tips for Onions, Garlic, Leeks

Alliums are tasty, versatile crops, including leeks, bulb onions, shallots, perennial onions, bunching onions, ramps, and garlic, that are key ingredients in a wide range of cuisines and recipes. While they aren’t difficult to grow, getting good production can be tricky. Here are a few good tips for onions, garlic, and leeks. 

Choose the Correct Variety for Your Area

Alliums can be a bit fickle about where they grow. Onions require certain lengths of daylight to bulb up properly, garlic needs specific temperatures, and leeks can require a long growing period. Choosing a Variety appropriate to your area is the only way you’ll have success.

Bulb Onions

We carry long-day (LD) and short-day (SD) type onions at SESE. You may also see intermediate-day or day-neutral onions available at other places. 

Long-day types begin to form bulbs when the day length is between 14 and 16 hours. Plant long-day type onions in the spring from Virginia northward. Note that not all long-day types can bulb up as far South as Virginia, but ours can.

Short-day types begin to form bulbs when the day length is between 10 and 12 hours. Short-day types can be spring or fall-planted in Virginia and fall-planted in the South. If started in a greenhouse or in the fall and kept refrigerated as sets, short-day onions can be grown in small bulbs in the North.

Intermediate-day or day-neutral onions are ideal for gardeners that live right on the edge, usually in zones 5 and 6. They aren’t daylight dependent and will produce well in almost any area.

Looking at day length isn’t necessary for bunching or perennial onions.

Garlic

At SESE, we carry four types of garlic; hardneck, softneck, Asiatic & turban, and elephant garlic.

Hardneck or rocambole garlic is better adapted to cooler climates and performs best from Virginia northward. It has become more popular recently because it produces flower stalks or scapes that can be cut and eaten before the garlic is ready to harvest. Hardneck garlic varieties have a diverse range of flavors.

On the other hand, softneck garlic does best in warmer climates and is more domesticated than hardneck garlic. It doesn’t produce scapes. However, the lack of scapes makes it easy to braid softneck garlic. It also stores incredibly well and typically has higher yields. 

Asiatic and Asiatic Turban garlic are tentatively identified as an artichoke subtype. Unlike most artichoke types, the stems are hardneck; however, in warm climates, they may revert to softneck. 

Though elephant garlic isn’t true garlic, it is cultivated in the same way. It has a milder flavor than other garlic, making it perfect for raw use. It’s also excellent steamed with other vegetables. 

Leeks

Leeks aren’t divided into specific categories like onions and garlic. They’re very similar to growing onions and, in some ways, are a bit easier. However, you want to consider each variety’s days to maturity, your climate or growing zone, and when you want to plant them. Leeks may vary widely in days to maturity from the 130 of American Flag (Broad London) Leeks to the 75 days of King Richard Leeks.

Water Management

Alliums don’t like soggy feet but produce better when kept consistently watered. Especially for large bulb onion varieties, regularly watering or using a drip irrigation system on a timer can significantly improve your yields.

Weed Pressure

Alliums do not tolerate weed pressure well. Onions, leeks, garlic, and other alliums can easily be overwhelmed by heavy weed growth and fail to produce well. We recommend spacing allium rows so you can easily weed between them with a stirrup hoe, wheel hoe, or similar tool while the weeds are still small.

Mulch

We recommend using a good layer of mulch for all allium crops as it helps with the above issues. Mulch will help keep the soil cool and moist and suppress weeds. If you have a wet season, you may want to pull the mulch back a week or two before harvesting garlic and onions to allow the bulbs and soil to dry a bit for harvest.

Invest in a Sturdy Garden Fork

It can be tempting to pull alliums from the soil by their tops without digging them. While this may work perfectly fine if you have nice fluffy soil, loosening the soil with a garden fork can be helpful for other gardeners. Trying to pull alliums without the help of a fork can break the stems, cause damage, and may lead to a shorter storage period. 

Alliums are valuable crops in the garden and kitchen but can be tricky to grow. Follow these tips for onions, leeks, and garlic for a productive year.

Top 10 Tips for Growing Heirloom Vegetables

Heirloom vegetables are favorite crops for many gardeners and farmers. We value them for their flavor, stories, diversity, and beauty. While some heirlooms can be tricky, many heirloom vegetables are as easy to grow as their hybrid counterparts. Many gardeners get started with hybrids because that’s what’s often available at local hardware stores and garden centers, but that doesn’t mean those beginners can’t grow heirlooms. Here are a few tips to ensure you have success growing heirloom vegetables. 

So What is an Heirloom Vegetable?

There’s no official definition of an heirloom. Heirlooms are just open-pollinated varieties that farmers and gardeners have saved for generations. At Southern Exposure Seed Exchange, we consider heirlooms to be open-pollinated varieties bred before 1940. Read more about why we grow heirloom seeds.

1. Select Varieties Carefully

You may find heirloom vegetables that are particularly well-suited to your gardening conditions. Growers carefully selected heirloom varieties over generations for specific traits. Sometimes these were traits like appearance and flavor, but often, these included good adaptation to local climatic conditions, disease resistance, drought tolerance, and other handy characteristics. 

2. Be Vigilant About Disease

No crop is resistant to all diseases, and heirloom vegetables are no different. Careful crop rotation, soil management, and cover cropping can help prevent a myriad of diseases. You should also practice good garden hygiene, removing diseased plant material and sterilizing tools that may have come into contact with diseased plants or soil.

3. Water Consistently

Avoiding over or under-watering can significantly improve your yields. Overwatering can lead to tomato splitting issues, increased fungal diseases, and poor-quality produce. Underwatering can lead to poor germination, failure to thrive, increased disease pressure, and other problems. Learn how to water correctly and consistently. Use a timer and drip tape if necessary.

4. Get Your Soil Tested

What seeds you bought doesn’t matter if your soil isn’t healthy. The best way to build good soil is to understand what you’re starting with. Getting your soil tested is quite affordable and well worth the effort.

5. Prune and Trellis Heirloom Vegetables

Especially in the hot and humid midsummer months in the south, good circulation is vital in helping prevent fungal disease, so prune and trellis your plants as needed. Trellises may also be necessary to avoid lodging on plants with heavy crops like larger pepper varieties. Crops you can trellis include tomatoes, peppers, winter squash, cucumbers, peas, pole beans, and more.

6. Space and Thin Generously

It can be tempting to cram more than is advised into your garden, but it may not be worth it! Follow spacing recommendations for larger plants like watermelons and tomatoes and thin smaller crops like carrots and beets as needed. A few appropriately spaced plants will be healthier and produce more than many tightly-packed unhealthy ones.

7. Use Mulch Around Heirloom Vegetables

We recommend mulching around any heirloom vegetable crop as soon as possible. Mulch helps prevent soil splash during watering or heavy rain, conserves moisture, surpasses weeds, adds organic matter, and helps regulate soil temperatures. 

8. Harvest When You’re Ready to Eat

While it’s not always possible, many heirloom vegetables especially tender crops like lettuce and sugary crops like sweet corn, are tastiest when prepared quickly after being harvested. If possible, try to eat, cook, or preserve produce soon after harvesting.

9. Get Transplants Off to a Good Start

If you’re starting heirloom vegetables like peppers, eggplants, tomatoes, and onions indoors, it’s essential to do it properly and ensure you grow healthy, productive transplants. Provide supplemental light, adequate water and drainage, proper temperatures, and pot them up as needed.

10. Save Seed

Saving seeds from your heirloom vegetables can help adapt a variety to your local conditions over time. You’re also helping to preserve a variety with future generations, saving a little money, and developing a new skill. Beans like those pictured above are a great crop to start with! Check out this post to learn to save bean seeds.

Growing heirloom vegetables is well worth the effort. They add incredible diversity, flavor, and beauty to your garden. If you’re growing heirlooms this year, follow these tips to help you succeed.
