test your soil texture, and try new peas and beans with ira wallace
READY TO SELF-TEST YOUR SOIL TEXTURE, and maybe also widen your definition of “peas” and “beans” to include some Southern favorites this year, no matter where you garden? Ira Wallace, Southern Exposure Seed Exchange’s well-known longtime home-garden expert and an author in the new “Timber Press Guide to Vegetable Gardening” series of regional guides (win one for your area!) tells us how.
The new series, in which Ira’s Southeast volume (Amazon affiliate link) is one of four so far, are filled with little tips, lists and charts–plus plant-by-plant growing guides, of course. In a conversation on my weekly radio program, she shared some sample wisdom. (Full details on how to subscribe to the show free, and how to win a guidebook, are at the bottom of the page.)
ira wallace’s diy soil test
Q. Since all gardening starts with the soil, Ira, one that really caught my eye was the DIY soil test with dishwashing powder and water in the glass jar.
A. I first came across the test back in the 70s, when I was a 4-H and Girl Scout leader. The area in North Carolina where I was living at the time had red clay (just like we do here in Virginia).
You can sort of tell what kind of soil you have by making a ball of it in your hand, but to be more clear about your soil texture—so you can have a better idea of moisture-holding capacity and how much organic material in the form of compost you need—this test is great.
You take a quart Mason jar, fill it one-third to half full with soil. Make sure you’re just getting soil, and not big clumps of grass; go below that, to sample the first 6 inches.
A trowel you use for planting bulbs is great for getting a soil profile.
Then add water until the jar is about two-thirds full, plus a teaspoon of powdered dishwasher soap, to act as a surfactant. If you’re having a lot of clay in your soil, it keeps it suspended enough–so that you have really good layering, between the sand, silt and clay.
Q. Those are the three components of soil—the different-sized particles, from large to small, of sand, silt and clay. A lot of people tell me that when they make compost they get “soil” when it’s finished, but of course that’s humus, or composted organic material. Sorry—I digress! Back to the test.
A. Yes. Take that jar and shake it up for about 3 minutes, then put it on the table, preferably in good light. Pretty soon, within 5 or 10 minutes, the sand particles will start to settle.
Q. So you’re looking at the layers, like an ant farm—and can see the proportions.
A. Yes—but the clay takes overnight to settle. And if the water is still cloudy after everything settles you have a good amount of organic matter in your soil, too—besides the soil particles themselves. If it’s clear water, on the other hand, you have your work cut out for you!
Q. Your chart in the new book of easy/medium/harder vegetables for people to try also intrigued me.
A. People ask this all the time: What can I start with? And so I divided the list further, into cool-season crops, and warm-season crops, and also into things you need a little space for—because so often people put a cucumber vine without a trellis in their raised bed, and it takes over the world.
Asparagus beans—the long beans you see in an Asian grocery store—are easy in warm season, for example. Bush beans (though we have to cover them here because of bean beetles) are easy, and they’re quick, and you can keep planting successions all summer.
Q. In your easy warm-season list you list some tomatoes as easier than others.
A. Cherry tomatoes and paste tomatoes are easier than some of the large-fruited tomatoes—and quicker.
Hot peppers are easier than sweet peppers. Lima beans are easy if you plant them once the weather is warm.
Okra is easy, too. Snap and snow peas are easy in the cool season; Southern peas in the warmer.
Q. Let’s talk about those legumes (since peas, at least, are an early crop to sow). Now I know to a Southern girl, the word “peas” doesn’t even mean the same thing as it does to this Northern gardener.
A. Down here we think of peas as actually being crowder peas [above right], or black-eyed peas [above left], but I know that Northerners think of “peas” as green peas [below, starting up a string trellis in Margaret’s garden in spring]. Mr. Jefferson used to have a neighborhood contest at nearby Monticello to see who would have the first “sweet English peas,” as they were referred to, from the garden.
We don’t have a very long season in spring for them, but we love them, and we grow a fall crop, too. I find that ‘Cascadia,’ for instance, is really good in fall for us, better at that time of year than ‘Sugar Ann.’
A. Here in Virginia, we plant around mid-February (then again in fall), and yes, you get a longer harvest by including several varieties.
We also make best use of our space with a technique called “relay planting” (also known as “intercropping”)—growing two different vegetables with different growth patterns and nutrient needs in one space.
In the early spring, we plant four rows of a quick-maturing spinach in a 4-foot-wide bed with a row of dwarf snap peas down the middle—or we might put peas in a bed of overwintering spinach. The last spinach is pulled around the time the peas are ready to start harvesting.
Other relay-planting ideas: tomato and lettuce (tomatoes 2-4 feet apart with the fast-maturing lettuce between), or radishes alongside the base of beans or broccoli. In the heat of summer we plant lettuce or spinach or parsley in the shade beside the taller crops.
Q. So what about “Southern peas”?
A. We use Southern peas not only to eat, but also as a cover crop.
There are many different varieties of Southern peas, from the mildest-flavored cream peas, to mild-flavored black-eyed peas, and stronger-flavored crowder peas.
With crowder peas, the bush can be sprawling and huge, and to control it in a small garden, you usually have to trellis it. I like ‘Colossus,’ with a big pea that’s easy to shell.
You can eat the peas two ways: When they’re still green (though not on the inside, where they are tan or another color) but when the pod is still green and the pea has just formed, or when harvested dry.
Q. The other most-familiar legume: beans. And again, down South you seem to grow kinds not everyone is familiar with, I suspect. Besides asparagus beans [above right], which you mentioned, any to suggest?
A. I recommend trying one that I learned from an English friend: fava beans [or broad beans]. We plant them in March here; people farther South grow them in the fall.
Runner beans—like ‘Scarlet Runner’—are something else recommended by my English friend. In England, they’re more common than other pole beans, and they eat them when they are young and green and tender. The runner bean plant is really a perennial—and some people here dig up the roots of their runner beans and put it away with the dahlias to overwinter, then replant them.
Greasy beans [above left] are pole beans that don’t have hairs on the pods, so they look shiny or greasy, and they stay tender after the seeds form in the pods.
And I highly recommend the ‘Red Noodle’ and Chinese mosaic types—also very long, and beautiful.
Q. A friend tosses them and just puts them on the grill in summer—one of her favorite grilled vegetables.
A. They’re great stir-fried in oil, Chinese-style, too.
- Southern Exposure Seed Exchange has a wide assortment of all these legumes.

- Bush and pole green beans: Phaseolus
