On a cold and snowy day I paused to think back a few years to a conference I attended run by the Ecological Farming Association in Pacific Grove, California. There were several sessions by scientists presenting research confirming what organic gardeners have always known: organic techniques yield plants that resist disease and insects better, and produce better-quality and healthier vegetables. I dug out my notes, and would like to share some of what I learned.

Dr. Larry Phelan, a research scientist at Ohio State University, explained that he wanted to see if organically grown plants attracted insect pests differently than those grown using conventional techniques. He collected soil from two farms that were across the road from each other. The soils were identical except for how they had been tended for the past several years. One farm was organic, the other conventional.

To reduce other variables, Dr. Phelan brought the soil to his greenhouse and potted it up in large containers. He then grew corn in the containers, adding chemical fertilizers in some, fresh cow manure in some, and composted manure in others, using both types of soil for each method. When the corn was at the appropriate size, he released corn borers into the greenhouse and watched what happened.

Not surprisingly, the corn borers preferred the corn grown conventionally. Not only that, but the long-term history of the soil also mattered. The soil from the organic farm had higher levels of organic material in it, and consistently was less attractive to the borers, even if used with chemical fertilizers.

Why should this occur? Dr. Phelan explained that plants evolved over the millennia getting their nutrients through the soil food web, depending on the symbiotic relationships between plants and microorganisms. Soils rich in organic matter provide much needed nutrients in a slow, steady stream, the way Mother Nature does it.

He said that when a plant gets too much nitrogen, the excess is stored in the form of amino acids, the building blocks of protein. For insects, this is like candy for kids: they can detect it, and go to the source.

Dr. Autar Mattoo of the United States Department of Agriculture Research Station in Beltsville, Maryland, also presented some very interesting findings. He compared the health of tomatoes grown with chemical fertilizer on black plastic to the health of those grown organically using a mulch of hairy vetch, an annual cover crop. He found that tomatoes grown with hairy vetch were dramatically better at resisting fungal diseases, especially those that cause blackening and dropping of leaves, which is often the bane of gardeners.

Dr. Mattoo explained that the vetch fixes nitrogen when growing. Which is to say it extracts nitrogen from the air and turns it into a form that plants can use. It was mowed down before flowering and allowed to stay on the surface of the soil, producing a considerable biomass to nourish soil microorganisms.

Compared to chemical fertilizer and black plastic, Dr. Mattoo found a 25 to 30 percent increase in yield using vetch. He explained that eventually the organic tomato plants would develop fungal diseases, but that for the first 84 days after transplant (late August for us), there was virtually no leaf blackening. At the same time, the tomato plants grown conventionally were severely damaged.

He attributed much of the difference to hormone signaling. Anti-fungal proteins can be produced when specific genes are activated, protecting leaves. He explained that depending on the environmental conditions specific genes are turned on or off. He was able to show this by photographing specific genes in the leaves of the tomatoes to see their size and thus their levels of activity. It appears that something in the vetch stimulated the tomatoes to produce those anti-fungal proteins.

What does all this prove? Being an organic gardener has many benefits, and scientists are just catching up with us! So as you plan your garden projects for the spring, think about giving up your use of chemical fertilizers.

It starts with a trip to the lumber yard

As I write this, the wind chill factor is well below zero, and summer seems a lifetime away. But if you are thinking about starting seeds indoors this year, this would be a good time to build a simple wooden plant stand. You don’t have to be a carpenter to build this, or have expensive power tools. Your local lumber yard will cut the pieces you need.

Mine is a simple A-frame, with one shelf, and the space for more plant flats on the floor. It stands about 4 feet tall, is 5 feet wide from end to end, and 2 feet from front to back at the base. It has space for four or five flats or trays, each of which will hold at least 32 plants — more if you buy the smaller six-packs that I avoid (some flats can hold 48 to 72 plants). And if at a later time you want to grow more plants, you can put another four flats or more on the floor and add lights above them.

The lumber for this cost me about $50 and the light fixture — a simple shop light with two 4-foot LED bulbs and a plug-in cord — cost $62, although often they are more expensive. Looking at catalogs, I see that one can easily spend much more for a pre-made plant stand. If you decide you like starting plants in the house, you could buy the extra lights next to illuminate more flats on the floor.

Here is what you need to buy for the model I built:

Four pieces of 1”x3” pine, 4 feet long

Four pieces of 1”x3” pine, 5 feet long

Two pieces of 1”x3” pine, 16” long, for cross bracing

One piece ¼-inch plywood, 18”x4’ (you can use thicker plywood if you have some)

One pair 3-inch strap hinges

4 feet of ¼-inch jack chain for hanging the lights and two small cup hooks to hang the chain

One 4-foot shop light with LED bulb and a plug-in cord

30 sheet rock screws (1¼” long)

Tools: portable drill with magnetic bit to fit the screws, and a measuring tape

Most lumber yards will cut all your materials to size for you but do not have small sheets of plywood. I found that Home Depot does have plywood in 2-foot by 4-foot sheets, and they cut mine to give me a piece 18” by 4’ for the shelf. You will need to ask them to cut the 1×3 pine boards as follows: four 60-inch pieces, four 48-inch pieces, and two 16-inch pieces.

Start by making two legs for your plant stand. Lay the 4-foot pieces end to end on the floor. Do it on your deck if possible, or next to a wall so that you can get them in a straight line by lining them up with something that is straight. Lay the hinges in place so that you will be able to fold them closed (most hinges only close one way). A cordless drill with a magnetic bit for Phillips screws will make your work much easier. To start the small screws on the hinges, make a hole first with a nail or awl, or a tiny drill bit.

Next close up the hinged legs and place them 5 feet apart on the floor. Place two of the 5-foot pieces on top of the first side. One should be screwed right at the top, one 24 inches from that. Flip over the stand, and do the same on that side. Stand it up, and spread the legs 2 feet apart at the bottom. Then add a cross brace on each end of the A-frame just below support pieces for your shelves.

Lastly you need to hang the light. Mine came with S-hooks and chain, which made hanging the lights easy. If yours do not, you will have to buy them. Most shop lights have slots and holes on the back side so that you can slip in S-hooks easily to hang them. You can also open a link of your jack chain and fit it in without an S-hook — just use two pairs of pliers to bend a link open. Screw two small cup hooks into a top cross piece and attach the jack chain. The chain will allow you to raise or lower the light — lights should be about 6 inches above the plants.

Starting seedlings indoors is miraculous for me — even after doing it for decades. I hold my breath waiting for germination, and fuss over the seedlings like a mother hen. And when I bite into my first tomato in August, I have the added satisfaction of knowing I brought that tomato into my world — with lots of help from Mother Nature.

Read the packets, don’t buy hybrid

As a boy in the 1950s I knew there were two kinds of tomatoes: deep red, plump and tasty ones my grandfather grew, and the kind that came four in a package wrapped in cellophane. The Cello-Wraps, as I think of them, had no flavor whatsoever. They were decorative. Sliced and added to our iceberg lettuce salads in winter, they added color.

My grandfather saved seeds from his tomatoes and started plants indoors in the early spring. He was not growing hybrid tomatoes like those sold in the supermarket. Hybrid tomatoes are carefully bred by crossing specific varieties of tomatoes so that they will have special characteristics such as surviving long trips in trucks, having a shelf life almost as long as a tennis ball, or resisting certain diseases.

My grandfather grew what we now call heirloom tomatoes: time-tested varieties that breed true from seed, generation after generation. Tomatoes that had been grown for many decades, seed shared with family and friends. Tomatoes so tasty that they were often eaten right in the garden, warm from the sun.

Examples of well-known heirloom tomatoes include Brandywine (often touted as the best-flavored tomato in existence), Cherokee Purple, Mortgage Lifter, Amish Paste and Black Krim. But there are hundreds of varieties of heirloom tomatoes, each unique and loved by someone.

All heirloom vegetables are what are called “open pollinated,” meaning that they will produce the same variety every year. Of course, in a packet of seeds some will produce better fruits than others. There is variety, but all Brandywines will take about the same length of time to reach maturity and taste about the same.

If you would like to start saving seeds, read the seed packet or catalog and make sure what you buy is labeled open-pollinated or heirloom, not hybrid. At the end of the season, save some seeds and store them in a cool, dry, dark place, perhaps in a sealed jar in a refrigerator.

I called Sylvia Davatz, the now-retired founder of Solstice Seeds in Hartland, Vermont, to talk about saving seeds. Solstice Seeds only grows and sells seeds from heirloom varieties, including some varieties from Europe.

She gave me lots of good advice, starting with the names of two good books on seed saving: The Seed Garden by Lee Buttala and Shanyn Seigel, and The Manual of Seed Saving by Andrea Heistinger. She recommends getting both books if you are going to be serious about saving seeds, as even among experts there are differences of opinion.

One of the reasons for having good books about seed saving is that they will advise you about such things as isolation distances to prevent mixing genetic material by pollinators or wind.

I asked Sylvia what vegetable species are the easiest to save. She said tomatoes, lettuce, beans and peas are all easy. They are self-pollinated and annuals. No insects are needed, and seeds are ready by the end of their season.

Vine crops like squash, pumpkins and cucumbers are insect pollinated and more difficult. If you’ve ever let a “pumpkin” grow in your compost pile from last year’s crop, you know that sometimes you get weird things due to cross-pollination — a pumpkin crossed with a summer squash by a bee, for example, may not be something you want to eat.

Most difficult in our climate are the biennials, things like carrots, beets, parsnips and parsley. These plants have to be kept alive all winter so they can flower and set seeds in their second year. You can dig up carrots and store them in soil in a bucket in a cold basement and replant them in the spring. But carrots, Sylvia explained to me, bloom about the same time as Queen Anne’s lace, a biennial wild flower/weed that can be pollinated by them — which would not produce the carrots you want.

Sylvia pointed out that in the not too distant past seed saving was the norm. Farmers and gardeners saved seeds from their best plants, knew how to do so, and knew how to store them. She explained that the seeds you save will usually be of better quality than seeds from a packet. They will have more vigor and a longer life span.

A good source for heirloom seeds is The Seed Savers Exchange. It has, since 1975, collected and stored seeds from gardeners and farmers. You can join their nonprofit or just buy some seeds or books from them. According to their website, they now store some 20,000 varieties in their collection, although at any given time only a fraction of them are actually for sale.

So think about saving seeds this year, even if only a few from your favorite heirloom tomatoes. And go to solsticeseeds.org to see a wonderful eight-minute video of Sylvia Davatz explaining all the importance and benefits of seed saving.

Start with an outline and some compost

This is a good time to make plans. If you are willing to spend just 15 minutes a day, every day, from spring to fall you can create an edible showcase for beauty: the splendid look of ripe red tomatoes, multi-colored Swiss chard or glossy green peppers. It’s not nearly as difficult as you think. And unlike maintaining a lawn, you get to eat the results of your labor. Here’s what you need to do:

To grow good vegetables you need sunshine, at least 6 hours a day and preferably more. For most people, the sunniest part of the yard is in the middle of the lawn. A well-maintained vegetable garden can be as gorgeous as a flower garden. And if you like flowers, you can plant some of those in your vegetable garden, too.

Don’t bite off more than you can chew — or weed. A nice lawn garden can be just 10 feet across and 12 feet long. Properly maintained, it will provide you with fresh veggies much of the summer.

Using string and stakes, define the borders of the garden and pry out the sod after cutting it into 1-foot squares with an edging tool or a spade. Use the sod to start a compost pile.

Start early enough in the season — say the first of May — so you can work just 15 or 20 minutes a day for a week or more to get all the grass out. That way you get in the habit of spending time in the garden, but don’t develop blisters or an aching back. Gardening should be fun, not hard work. Still, it can give you a workout without going to the gym.

Your lawn garden will have two raised beds separated by a walkway. Once you have removed the sod, you can just mound up the soil to form beds about 30 inches wide with a walkway up the middle and a 6-inch space between the lawn and the beds all the way around the garden. To do this, (after removing the sod) loosen the soil with a garden fork, shake out the soil and then rake the soil from the perimeter and the walkway onto the beds.

Then spread out five bags of composted cow manure on each bed (each bag is usually labeled 30 quarts), and work it into the loose soil with your garden fork or favorite hand tool.

Alternatively, you can build wood-sided beds using ordinary 6- or 8-inch-wide planks. For more years of service, 2-inch-thick lumber is even better. Gardener’s Supply (www.gardeners.com) sells a variety of brackets for building raised beds, and I suppose others do, too.

If you build wood-sided beds you will have to buy more filler than if using mounded beds. Most garden centers sell topsoil and compost by the tractor scoop, which is usually two thirds of a cubic yard of material. They’ll dump right into the back of your pickup truck, or even deliver (for a price). I recommend a mix of topsoil and compost, a 50-50 mix.

If you make wood-sided beds you can place them right on the lawn without removing the sod, which saves a lot of labor. Just scalp the grass with the lawnmower and put a thick layer of newspapers over the lawn, then fill the box. Long carrots might hit the bottom the first year, but most other plants won’t be bothered.

What to plant? Make a list of the veggies you like best and that taste best freshly picked. If you plant tomatoes, dedicate at least 24 inches of a row to each plant. And buy those wire cages for your tomatoes, so they won’t flop over and shade out your carrots or broccoli nearby.

I like to plant lettuce seedlings all around the tomatoes at the beginning of the season while the tomatoes are still small. By the time the plants get big, the lettuce will have been harvested and eaten. Run your rows north-south, and plant tomatoes (or any tall plants) on the north end of the garden so they will shade other plants less. Buy some bagged organic fertilizer and stir some in at planting time.

Oh, and about those weeds: The easiest way to prevent a problem is to mulch. Put down six sheets of newspaper and cover it with straw, mulch hay or last fall’s leaves. This will keep the soil dark, turning off the switch that weed seeds have to tell them when to germinate. Mulch also holds in the moisture during dry times. But when a few weeds do turn up — and they will — be sure to pull them before they get big and make more seeds. That’s preventive maintenance.

Gardening is said to be a middle-aged sport. After all, what parent of three toddlers has time to weed? But if you wish to reduce your food costs and feed your family well, a garden is great. And done this way, you can maintain it in 15 minutes a day. I promise. Just keep at it daily, and you’ll be surprised and delighted at how good your garden looks, and how much food you can grow — right in the middle of the lawn!

The spring flower shows are always a contrast to the cold, icy days of winter. Bright flowers, garden paraphernalia and numerous workshops make these events fun, for both beginner and expert. Here are this year’s offerings.

The first show of the season is a specialty show: orchids. The New Hampshire Orchid Society is holding its annual get-together Friday, Feb. 10, to Sunday, Feb. 12, at the Courtyard Marriott in Nashua. This is the show for orchid lovers. There will be vendors of orchids from Ecuador, Taiwan and the U.S. Members of the Society will bring their orchids to compete and to strut their stuff. Admission is just $10, or $8 for seniors.

Next up is the Connecticut Flower and Garden Show Feb. 23 to Feb. 26. This is a mammoth show with more than 3 acres of displays. As always, it is being held at the Connecticut Convention Center in Hartford, Connecticut. Tickets are $20 at the door, or $17 in advance. Kids 5 to 12 are $5.

One of the greatest things about this show is the educational seminars. Here are a few workshops that interest me: “Good Bug, Bad Bug, Benign Bug.” This is great for anyone who tends to squish any bug in the garden even though most are not a problem. I assume there will be slides of insects we should recognize but probably don’t. Then there is one on organic lawn care, and another called “Shady Characters.” I know garden writer Ellen Ecker Ogden of Vermont will do a nice slide presentation and talk about kitchen garden design and how to make your veggies look artful. She always does.

One of my favorite shows is always the Vermont Flower Show. It will take place this year March 3 to March 5 at the Champlain Valley Expo Center in Essex Junction, Vermont. The theme this year is “Out of Hibernation! Spring Comes to the 100-Acre Wood,”a tribute to Winnie-the-Pooh.

The main garden display is always a collaborative effort by members of the Vermont Nursery and Landscape Association. For three and a half days members of VNLA will work together to create a 15,000-square-foot display using their own and donated materials. Other shows tend to have displays by professionals that are competing with each other, but not in Vermont — they work together.

There will be more than 100 vendors and 35 workshops to attend over the three days of the event. In the past I have purchased seeds, seed potatoes, bulbs, books and garden tools. Tickets are $25, or $20 for seniors. Kids are $7.

The Vermont show is a child-friendly event with a craft room open all day. Go online to see the schedule of events for kids — there will be a magician, marionettes and music. Be sure to attend this year — it only occurs every other year.

A bit farther afield there is the Philadelphia Flower Show. Last year they held it outdoors in May due to Covid concerns, but this year they are back inside the Pennsylvania Convention Center in downtown Philly March 4 to March 12. According to their publicity, “The PHS Philadelphia Flower Show is both the nation’s largest and the world’s longest-running horticultural event, featuring stunning displays by premier floral and landscape designers from around the globe. Started in 1829 by the Pennsylvania Horticultural Society, the Show introduces diverse and sustainable plant varieties and garden and design concepts. In addition to acres of garden displays, the Flower Show hosts esteemed competitions in horticulture and artistic floral arranging, gardening presentations and demonstrations, and special events.”

I’ve been to the Philly show a couple of times and I am always amazed by the sheer size and diversity of the displays, vendors and workshops. It is best to go mid-week when crowds are smaller, and take two days, if you can, to see it all. Tickets are $43.50 for adults and $20 for kids.

A show I have yet to attend is the Capital Region Flower and Garden Show in Troy, New York, which will be held again this year at Hudson Valley Community College in Troy from March 24 to March 26. According to their website, there will be 160 vendors and exhibitors and eight to 10 workshops each day.

Then in May there is the New Hampshire Farm, Garden and Forest Expo being held this year at the Deerfield Fairgrounds on May 5 and May 6. It is now in its 40th year and is the least commercial of all the shows. It is focused on sharing information.

Finally May 23 to May 27 there is the Chelsea Flower Show of the Royal Horticultural Society (RHS) in London, England. I’ve been, and it was well worth the trip. It’s held outdoors and is truly wonderful.

If you plan to go to Chelsea, join the RHS to get better access times and pricing. Members get a discount of over $10 per day, but prices still range from $89 to $46 depending on the day of the week. British women tend to dress up for this show and wear big colorful hats. The first two days are for members only, so it should be a bit less crowded.

The spring flower shows are fun — and we deserve that after a long New England winter.

Look for old favorites and new varieties

We gardeners love our home-grown vegetables. As John Denver sang long ago, “Only two things that money can’t buy and that’s true love and homegrown tomatoes.” And why do they taste so good? We can grow tomatoes that don’t have to conform to commercial requirements of size, shape, color and transportability. Our soils generally are rich in compost or manure and host a wide range of minerals and microorganisms that enhance the flavors of our vegetables. And of course we eat them fresh from the garden.

We can taste five flavors: sweet, sour, salty, bitter and umami. These flavors were important to our evolution as they told early humans what was safe to eat and what to avoid. The fifth flavor was not named until the last century: Umami signals available protein in meat, eggs, milk and beans. It is not as easily described or identified as the other four, but it is sometimes described as the flavor of contentment.

So how can we recognize the complex flavors of a good stew, and aged cheese or a bowl of exquisite ice cream? Our noses can recognize many thousands of distinct scents, and our noses and tongues work together to create tastes. Good chefs recognize this, and many farmers do, too. I recently read a book that contains interviews with fine organic farmers who treasure their soil and what it imparts to the scents and flavors of the food they grow.

That book, by Michael Ableman, is Fields of Plenty: A Farmer’s Journey in Search of Real Food and the People Who Grow It. Ableman, an experienced author and organic farmer in British Columbia, spent three months traveling around the States in a 15-year-old VW van. He went with his 23-year-old son back in 2004. They camped out, ate local food and met with organic farmers, some of whom were growing food for the best restaurants in America.

There is much to love about this book: Ableman is a skilled writer and storyteller, he is a talented photographer, and he is adventurous and inquisitive. Not only that, he included recipes from many of the farmers, and they all sound delicious — and mostly vegetarian.

Each of these farmers he wrote about had a unique approach to farming. One let weeds grow rampant. Another had fields that were weed-free and managed with “precision, control, formal science and discovery.” But all ate their own food, fresh from the field — or in the field. And each interview gave me something to think about, and perhaps to apply to my garden.

One of the most startling interviews was with Bob Cannard in Sonoma, California. Raised on a farm, Bob went to agriculture school but dropped out and started his own farm. When starting out, Bob grappled with this question: Why are natural places naturally healthy, while the fields and orchards of commercial agriculture are a continual battleground with weeds, insects and diseases?

His approach to farming was to try to mimic nature — weeds and all. He believed that plants that struggle to survive would develop more complex flavors — a belief later adopted by some wine makers. He believed that a monoculture — acres of the same crop — encouraged insect pests to arrive and necessitate insecticides. He succeeded as a farmer, selling vegetables to Chez Panisse and other high-end restaurants in San Francisco.

I was fascinated to read the section on Strafford Organic Creamery in Vermont. Earl Ransom has a small herd of Guernsey cows and bottles their milk in glass bottles and makes fabulous ice cream, which I know and love. Ransom believes that he gets wonderful flavors by letting his cows graze in pastures with a variety of grasses, wildflowers and weeds. Diversity in the field creates better milk, and the fat in milk absorbs flavor.

The book provides the names of many varieties of vegetables that are exceptional. Organic farmers Gene and Eileen Thiel of Joseph, Oregon, specialized in potatoes and particularly like LaRatte, Yagana and Sante. Sante, he said, is like a Yukon Gold, but bigger. Yukon Gold also got high marks, as did Ranger Russets and Yellow Finn. They avoid losing his crop to blights, in part, by growing lots of different kinds of potatoes — as did the Incas, where potatoes came from. Of course there is no guarantee that a potato that does well in Oregon will do well for you.

Ableman, a farmer for decades, mentions some of his own favorite vegetable varieties. For sweet peppers he likes Ariane, Red Lipstick (I want to grow it, if just for that name) and Corno di Toro. Then there is the Charentais melon, about which he waxes poetic.

Of beans, varieties mentioned as excellent include Valentine and Sophia flageolet shell beans, Maine Yellow Eye, Vermont Cranberry and Red Streaked Borlotto. According to the book, thin-skinned dry beans are easier on the digestive system: “the skins harbor the chemistry that causes digestive problems.”

It’s time for all of us to be studying seed catalogs and seed websites to pick the vegetables we’ll grow this year. I’ll be referring to Ableman’s book for new varieties, but also going back to my old favorites.
