Gardening for a community

I recently went to Brattleboro, Vermont, to meet with the organizers of Edible Brattleboro. It is an informal group of people who believe that “access to fresh healthy food is a right for all, regardless of means. This serves as the basis of the work we are doing, and we do our best to eliminate barriers to benefitting from our work, and thus everything we offer is free.”

The prime movers behind this movement are Tom Green and Marilyn Chiarello, who have been working to turn empty spaces and lawns into places for food production. Both are retired school teachers. Marilyn saw a TED talk by Pam Warhurst in 2015 and decided that something similar could be done in Brattleboro.

That first year Edible Brattleboro approached the local food cooperative and asked for a strip of land between the parking lot and the Whetstone Brook. The Coop agreed, and volunteers built a 4- by 8-foot raised bed. They have since expanded this space, growing strawberries, tomatoes, herbs and more. Volunteers plant, weed and water as needed. Anyone can help themselves to the free food; there are no questions asked.

By now there are gardens and fruit trees all over town that were started by Edible Brattleboro. I went around with Tom and Marilyn and looked at some of their projects. Three cherry trees are planted in front of the town hall, and other fruit trees are planted on school property. Another garden is at an addiction recovery center, Turning Point, where there are raised beds in the front lawn.

Another garden is at the Root Social Justice Center, at the edge of their parking lot. Volunteers made container gardens using food-grade plastic 55-gallon drums using designs Tom found online. They have water reservoirs so that water wicks up into the soil in the drums, and daily watering is not needed. Tom also got some one-cubic-meter “intermediate beverage containers” that originally held sugar syrup. Again, he fitted them with water reservoirs to avoid daily watering.

Edible Brattleboro has had good luck getting small grants to support their activities. Although not a 501(c)3 themselves, they work under the auspices of Post Oil Solutions, a local nonprofit that sponsors them. But they will work with any organization that will help in their efforts.

Often low-income residents do not have the tools they need to garden. Fortunately, in Brattleboro that is not a big issue as the town library has a “lending library” of tools and kitchen equipment that they furnished with a grant from the Vermont Foodbank. The library’s grant included money to purchase a simple wooden structure in their parking lot to house the tools, and a part-time librarian to check out tools at specified times. For beginning gardeners, having a source for the basic tools can be an important saving.

We also visited a large greenhouse for extending the season and growing things like tomatoes and peppers in a controlled environment. Tom Green and volunteers put it up this winter, and they look forward to using it shortly. It sits on space offered by the Brattleboro Retreat Farm, a nonprofit.

There is a weekly farmers market in Brattleboro and Tom and Marilyn couldn’t say enough good things about the generosity of the farmers. At the close of the market each week volunteers from Edible Brattleboro visit the market and collect produce donated by farmers. They got a grant to buy a large refrigerator to hold perishables, and have an outdoor “Share the Harvest” table the next day at Turning Point.

So what can you do? All communities have both gardeners and people in need. What is needed in most towns are people like Tom and Marilyn. People with a commitment to helping, time, and organizational skills. Except for Tom’s work building the green house and large self-watering containers, no special skills were needed for what they have done.

Some sort of organizational structure is needed. I like the idea of joining up with an existing nonprofit so that grants and donations can be made to a certified 501(c)3, allowing donors to take tax deductions. That also lets people know that their money will be used properly.

There are organizations you could link up with, perhaps. You probably already know about soup kitchens and food banks in your town or a nearby town. So you could plant a little extra this year with the idea of sharing. Or you could help to organize others in your area to join with you.

Churches are another good place to start gardens. They generally have lawns in full sun, and people who want to help others. The soil in any lawn generally needs improving, but I bet most farmers would be delighted to donate some compost or composted cow manure to add to the soil. Garden centers are generally willing to donate some seeds or seedlings when the time comes, or perhaps a few bags of compost. So all you need is people power. I bet you will be gratified at how willing others will be to help.

Early-in-the-season gardening chores

I’ve finally had a few days of dry weather with temperature in the 50s, so I have been able to start some spring cleanup. Some of my beds are still too wet, so I will wait on working there until my feet don’t sink in. Walking on wet soil compacts it, ruining soil structure.

My first chore is always to rake up the sand and gravel that the snowplows leave on my lawn. I use a straight-edged shovel that is made of aluminum and is sold for barn cleanup. I rake the sand into the broad shovel, and dump it into a wheelbarrow. If I see that the grass is being pulled up, I wait until later, when the grass has fully woken up.

Next on my list is to pick up any downed branches. Winter always does some “pruning” of dead branches. If I can reach any jagged tears where branches have broken off, I snip or saw them back to the trunk or the branch where it originated. And this is a good time to take off those plastic wraps that protect young trees from mice and voles.

I don’t generally rake leaves out of my flower beds in the fall, as I like the extra protection against erosion and cold temperatures they provide. But that means that bulb plants are covered now, and the ground is insulated from the spring sun. I want the soil to warm up. So I try to clean up places where I know there are spring bulbs as early as possible.

If the daffodils are poking through, I use my fingers to pull back the leaves. I fear that a rake will damage the tender stems and flower buds. In other places where bulbs are not up yet, I use a rake and gently rake off the leaves. Sometimes I will bring along a scrap of plywood or a 6-inch plank to stand on as I work, minimizing compaction.

This is when I prune blueberry bushes. By now it is easy to identify the fat, round fruit buds as opposed to the skinny little leaf buds. I remove branches that aren’t producing fruit, allowing for more sunshine to get into my plants.

For the past few years a foreign fruit fly has badly damaged blueberry crops. The spotted-winged drosophila (SWD) infests ripening fruit, causing it to get mushy and unpleasant. This is in contrast to ordinary, native fruit flies that only lay eggs in over-ripe or rotting fruit.

At present the only way I know that organic growers can prevent damage is to cover bushes with row cover or a very fine mesh. But that is a big bother when it is time to start picking. The SWD appears fairly late in summer, so early-ripening varieties can sometimes avoid them.

Of course if you haven’t cut back all your perennials, spring is a good time to do that. I like to wait until spring to cut back some perennial flowers with seeds. Finches and other seed-eaters enjoy the seeds, particularly when bigger, greedy and aggressive birds or squirrels are hogging the seeds at the feeder.

In the fall I usually do a good job of weeding and mulching the vegetable garden with fallen leaves or straw. In the spring I rake the mulch of my wide raised beds so that the sun can help to dry out and warm up the beds. I leave the mulch in the walkways to inhibit weeds, and later I will add new mulch around my tomatoes and other plants.

My roses haven’t woken up yet, or not by the time I wrote this, but will soon. I have a dozen or more roses and most are very hardy. I particularly like the Knockout rose series. They are very resistant to diseases, do not seem to attract Japanese beetles or rose chafers, and are very vigorous. But each spring I need to cut back the canes to a point where the tissue has not been winter damaged.

You can easily tell if the stems of your roses are alive by rubbing a stem gently with your thumbnail. If it shows green, it is alive. If it is not green, it is dead. Cut back any stem to a place where there is a bud on tissue that is alive. Or you can wait until they leaf out, and cut back the dead parts. If you have a few shoots that got much taller than the rest of the plant, you should cut those back for aesthetic reasons.

Spring is also a good time to pay attention to the “volunteer” shrubs and trees that show up uninvited. There are several invasive species that birds plant seemingly “willy-nilly” anywhere they perch. Seeds pass through them and start growing without your help. But you should pull these shrubs and trees before they get so big you need a backhoe!

Here are some to look for: bush honeysuckle (Lonicera spp.), barberry (Berberis thunbergii), burning bush (Euonymus alatus), Autumn Olive (Elaeagnus umbellata), blunt-leaved privet (Ligustrum obtusifolium) and the vine Oriental bittersweet (Celastrus orbiculatus). Norway maple (Acer platanoides) and common buckthorn (Rhamnus cathartica) are trees that are also common and invasive.

Why worry about invasives now? They are more obvious in the landscape. Most get a jump on the growing season by putting on leaves while our native plants are still asleep. Plus, you have time now. So go dig them out if you can. Cutting them down usually just stimulates them to set up many new plants from their roots.

Later, when spring warms up, we will be planting our veggies and annual flowers so we won’t have time for many of these activities. So get out there on the next nice day.

Plant summer-blooming flowers now

I like dahlias. They are bright and come in many colors with blossoms from the size of daisies to the size of dinner plates. My wife, Cindy, loves dahlias. Every year we have discussions about how many we should plant and where they might go. I believe there is such a thing as too many dahlias. Cindy does not.

Each fall we dig up our dahlias a week or so after the first hard frost but before the ground freezes. We store them in a cool basement in boxes filled with sphagnum moss or sawdust that is lightly moist. The problem is, each plant produces a dozen or more tubers, and each and every one will produce a new plant the next summer.

If you have purchased dahlia plants at a greenhouse in the past, maybe this year you would like to try planting some tubers. They tend to be less expensive, and there is definitely more variety. Go to your local garden center or go online and order tubers.

Choose a 6-inch pot and fill it three quarters full with potting soil. Place the tuber so that it is lying flat on the surface, and cover with a few inches of potting soil. Pat it down, water lightly, and let it be. When it is ready, it will send up shoots and then it will need some bright lights. They have tiny “eyes” or growing points, and if you can spot one, be sure to plant it on the top side. But eyes are not always easily identified.

I grow ours on a plant stand with fluorescent lights and have never tried them on a bright windowsill, but I guess that would work, too. If you find your plants on a windowsill are floppy or pale, switch to artificial lights if you have them.

I love calla lilies. These beauties are not true lilies at all, but members of the Arum family (which includes Jack-in-the-pulpit, skunk cabbage and the house plants dieffenbachia and philodendron). Calla lilies are perennial in warm climates but, like dahlias and gladiolas, must be dug and brought inside before the winter here. Now is the time to start some calla rhizomes (a bulb-like modified stem) indoors. Plant them with the smooth side down.

One of the advantages of growing calla lilies is that they are not true lilies, hence not bothered by that dastardly red bug, the lily-leaf beetle. The lily-leaf beetle attacks Oriental and Asiatic lilies that I do so love but have given up growing. Calla lilies also bloom for a much longer time than true lilies, though they lack the fragrance of Oriental lilies.

To start calla lilies indoors now, buy rhizomes now at your local garden center or from a reputable supplier. The rhizomes need to be planted about 3 inches deep, then covered with potting mix. It is a good plant for people who tend to overwater their houseplants, as they thrive in moist soil. (By the way, start doubling the water to your rosemary plants if you over-wintered any. Otherwise they will dry out and die).

Once summer is here you can either transplant your potted calla to a nice sunny spot, or keep it in the pot and move it outside. Come fall, you will need to bring them inside, as temperatures around 20 will kill them. Callas need to go dormant in winter.

When buying some calla lily rhizomes at my local garden center, I also bought some gladiolus corms (commonly called bulbs). My gardening grandfather loved growing gladioli, and won ribbons at the Worcester, Massachusetts, county fair most years.

Gladiolus corms are relatively inexpensive so most gardeners don’t bother saving them. Classic colors are red, yellow, pink and purple. I recently bought bulbs that will produce flowers with pink, white, and white with pink designs at my local garden center. I will wait and plant them directly in the soil in my garden in June.

Another summer beauty is the canna lily. We grew some that were 6 feet tall last summer and they bloomed from mid-summer till fall. Buy rhizomes now and start them indoors to get a good jump on the season. They come in various sizes, and with green or purple foliage.

My favorite summer bulb plant is called a variety of common names: peacock orchid, sword lily, or fragrant gladiolus (even though this plant is not an orchid, a lily or a gladiolus). That’s why I like Latin names. If you ask for acidanthera murielae, plant-knowledgeable people around the world will know what you mean. But for now, I’ll refer to it as sword lily.

The sword lily has long, narrow leaves — like swords — that stand 18 inches or more tall. The blossoms are white with deep purple markings in the center of the six-petaled flower, along with a little yellow at the very center. You get two or three blossoms per stem, and they are enticingly fragrant, particularly in the evening. I’ll plant them now, eight to 12 bulbs 3 inches deep in a 12-inch pot, and grow them on the deck this summer.

I don’t know about you, but I need all the green growing things around me I can get as mud season lingers on. So get your summer bulbs now, before they are all sold out, and start a few indoors.

Easy to grow and trouble-free

Every year you probably plant tomatoes. Wouldn’t it be great if they would come back every year without the bother of preparing the soil, starting seedlings in April and setting them out? Well, that’s what nut and fruit trees and berry bushes do: Once planted (and mature), they produce food every year. To me, there is a definite allure to plants requiring less work.

I recently was sent a review copy of a wonderful book by Allyson Levy and Scott Serrano: Cold-Hardy Fruits and Nuts: 50 Easy-to-Grow Plants for the Organic Home Garden or Landscape printed by Chelsea Green Publishing. When I got it I could barely pull myself away from it because it has so much to teach me.

Each of the species included has five or six pages devoted to it and at least five excellent photos. The information starts with “Growth Difficulty Rating” — how hard is it to grow? Most are easy. It includes taste profile and uses, pollination requirements (is it self-pollinating?), site and soil conditions, zone hardiness, good cultivars to look for, and a paragraph on pests and problems, and more.

I called the authors and asked about their experience growing this diverse group of plants. They live in Stone Ridge, New York, a town about 100 miles north of NYC and 10 miles or so from the Hudson River. They are in Zone 6, where winter temperatures only go a little below zero most winters.

They are both artists, and originally started growing plants to use in their art. About 20 years ago they bought 8 acres across the street from them and started their own arboretum, later adding another 10 acres. Their arboretum is Hortus Arboretum and Botanical Garden and is a Level II arboretum according to the Morton Arboretum.

I asked them what they would recommend for fruit if someone had none and wanted to start with winners. Scott suggested blueberries and blackberries. Both are easy and tasty. Elderberries are good, too, they said, although you need to cook the berries to make them palatable. Elderberries, honey and lemon juice make a nice syrup, which I use to help prevent colds in winter.

We talked about honeyberries. It’s a fruit I will definitely plant this year. Although the fruit looks a little like a big oblong blueberry, it is actually in the genus with honeysuckle. It is native to the northern U.S., Canada and Siberia. A friend gave us a few to taste last summer, and I like the flavor.

According to the book, honeyberry is the first fruit to ripen here, a couple of weeks before strawberries. But it is a couple of weeks after they turn blue and look ripe that they actually lose their astringency and turn sweet. This is the kind of information that most books or plant tags don’t have, and only comes from someone who grows and knows the plant. Allyson said she discovered that lots of berries are hidden under the leaves. The fruit gets better every year, apparently.

Another fruit in the book is pawpaw, a somewhat tropical-flavored tree fruit (banana crossed with mango flavor?). As the book explains, you need two different trees (not clones) to get pollination and fruit. I am growing it, but started out with only clones, so I have not gotten fruit yet.

Of the nuts, they recommend hazelnuts. These produce nuts as much younger plants than things like black walnut or pecans, which are tall trees that require years to produce nuts. You need to have two or more hazelnuts as they are not self-fertile. Scott pointed out that the native species has smaller nuts than some of the named varieties.

Pecans are discussed in the book. The biggest difficulty is not growing the tree, but having a growing season long enough for the nuts to ripen. They need 150 to 180 days. But as the climate changes, perhaps this will not be a problem in 25 years. They note that you must have two compatible grafted varieties to get nuts, as the trees are not self-fertile. These are big, handsome trees and should be grown in full sun and rich soil if possible.

A tree that is not native but produces a lot of food for deer is the Korean stone pine. The pine nuts we use for pesto are most often from these trees grown in Asia. The cones open up in winter and drop their seeds, which are rich in oil and high in calories. Scott said in Siberia tigers indirectly depend on the stone pine because they feed the deer and boar the tigers need to survive.

The Hortus Arboretum and Garden is open from Mother’s Day in May until the end of October, Friday to Sunday. Admission is by donation. Because of Covid, they have been scheduling visitors online during the season at their website, hortusgardens.org.

This book is terrifically useful to anyone interested in growing fruit and nuts. I should note that it does not cover apples, plums and peaches because those fruits are well-covered by other writers, and, as they say, much prone to pests and diseases. The plants discussed are generally easy to grow and trouble-free. Just what we all want!

A key step toward successful gardening

This is a good time to beat the rush and get your soil tested so that you can improve your soil before you begin planting.

Most New England states have soil testing labs available to gardeners. Finding one is as simple as searching for “Soil testing lab near me” in your browser. Your first choice should probably be one run by the state university extension service. Most offer a variety of options as to what is tested, and their websites will explain your options, what each costs, and how to collect a sample. Most tests require one or two cups of air-dried soil free of roots and rocks.

Most state labs are very busy in spring, and a 14- to 21-day wait is typical. If you are in a rush to get your soil test results, you might try Logan Labs, a commercial lab in Ohio. They can usually email test results in a few days and also have a soil scientist available to talk to you (for a fee) to make recommendations.

Unless you live where there are natural limestone or marble deposits — parts of Vermont, for example — your soil is probably acidic. Why? Coal-fired power plants send sulfur into the air, and it reacts with water to form sulfuric acid that is dropped by the rain. Most plants do best with a soil pH between 6.0 and 6.8. A pH of 7.0 is neutral, and above that is alkaline. Soils rich in organic matter and microorganisms tend to buffer the soil pH, making it less acidic.

Soils are composed of three things, basically: ground up rock is about 45 percent, air is about 50 percent and organic matter about 5 percent. The particle size of the rock component is what determines soil texture: big particles are in sand, medium particles in silt, and very fine particles make up clay. A good soil has particles of all three sizes, but is mostly silt.

You can see what is in your soil by filling a quart jar half full of water, and adding a couple of cups of soil, and then shaking it well. Sand will drop to the bottom pretty much immediately, and silt will drop next. Finally, after 24 hours or so, your clay will form a layer. Each will probably be a different color and quite obvious. Organic matter often floats on the surface, but generally mixes with the silt layer.

Clay holds on to soil minerals and moisture the best, but it can stay soggy and also get compacted. Sand particles are not electrically charged, so they don’t hold on to minerals like clay or silty soils, but the sand helps with drainage. You can get a feel for your soil by rubbing it between your thumb and a finger after wetting it. Clay soil is sticky. You can feel the grains in a sandy soil.

If your soil has a pH of 6.0 or less, you should add some garden lime or wood ashes to “sweeten it.” If you get a soil test, it should tell you how many pounds of lime to add as expressed in pounds per 100 square feet — a 10 foot by 10 foot area. I weighed a quart of garden lime in a yogurt container and it weighs a little over 3 pounds. Wood ashes are about equivalent in what they do. But this isn’t rocket science — you don’t have to be precise.

Lime is ground limestone and is sold in bags at the garden center. It comes as powdered lime or pelletized lime, which is less messy. If you buy powdered lime, wear a mask when spreading it so you don’t inhale it.

All fertilizers add nitrogen (N), phosphorus (P) and potassium (K). The amount of each is expressed as a number that is the percentage of the active ingredient by weight. A 10-10-10 fertilizer has 10 percent of each, and 70 percent filler. The minerals in chemical fertilizers are in the form of salts, and using too much can damage roots. The salts in chemical fertilizer are water-soluble and can be dissolved and washed away in heavy rains.

Organic fertilizers, on the other hand, are made from natural ingredients and minerals from ground rocks. My favorite organic fertilizer, Pro-Gro, is made in Vermont and has things such as peanut meal, cottonseed meal, ground oyster shells, feather meal, crab meal, dried blood (for nitrogen) and rock phosphate. I like to compare it to a seven-course meal for plants.

The ingredients of an organic fertilizer mostly need to be digested by microorganisms found in the soil and then shared with green plants. They are gentler, and slow to release their goodies. The mineral content of Pro-Gro is listed as 5-3-4, which is lower than most chemical fertilizer, but offers all those micronutrients not found in chemical fertilizers.

Of course you can go the old-fashioned way and add animal manures to improve your soil. They work, but some may also introduce weed seeds. I don’t recommend using fresh horse or cow manure because of that, but manure that is a year or two old has fewer seeds. Rabbit, sheep and goat manure has fewer weed seeds, and they add plenty of organic matter that helps with texture and tilth.

If you add compost to your garden and work it in, it will become more biologically active — full of beneficial microorganisms. It will drain much better but hold moisture better, too.

Having good soil is one of the keys to being a good gardener. Perhaps testing and improving your soil will help you to have that elusive green thumb. It’s worth trying.

How to not kill your fruit tree

Traditionally, farmers pruned their fruit trees and put wood ashes around their lilacs in March. And although this is a good time for both, you can do either earlier or later. I believe that because farmers couldn’t plant or work the soil in March, they did other tasks to fill up their days — such as pruning.

If you plan on pruning now, please be aware of the danger of compacting the soil. Compacted soil has few air spaces — and plants get their oxygen from their roots, not their leaves. Roots from trees can extend well beyond their dripline and can be damaged by your footsteps if the soil is soggy.

If the soil is still thawing and is wet, it’s better to stay off it for now. If you have light, sandy soil that drains well, then you are fine. Clay soils are most at risk for compaction. Once you compact the soil, it is less able to drain away excess water, too. Just remember that the soil can freeze deeply — two feet or more, depending on snow cover — and a layer of frozen soil is like a layer of concrete. If you leave footprints in the soil, don’t walk on it.

Don’t be afraid to prune, even if you have never done it before. Fruit trees grow vigorously when pruned, and even if you remove a branch and then wish you hadn’t, other branches will grow and fill in the space. You can safely remove about 25 percent of your branches and leaves; your tree will still have plenty left to grow fruit and feed the roots.

Use a sharp pruning saw. You will rarely have to remove anything more than a 2- or 3-inch branch, so a folding tri-cut saw will be fine and can be purchased for around $25. Bow saws are not able to get in tight places, so are not recommended. A chainsaw is rarely needed, and can easily remove too much wood too fast!

What should you remove? First, remove any dead branches. How do you know if the branch is dead, since there are no leaves? The bark will be flaky and a different color from healthy branches. For smaller branches, scrape the bark with your thumbnail. If it does not show green, it is dead.

Ideally, sunshine can reach every leaf of the tree. Leaves shaded by others do little to feed the tree. So if you have branches layered closely, one above the other, the lower branch is being shaded. Either remove it, or remove the one above it.

Often branches grow back toward the middle of the tree. These will create problems as they get larger, often rubbing existing branches and shading out others. So follow them back to their point of origin to remove them. Remove any branches that are rubbing or touching. Decide which is the better branch, and leave it.

Where should you make your cuts when removing a branch? Look carefully and you will see the “branch collar.” You will want to leave the collar as this is where the cut will heal. It is a swollen area where the branch and the trunk or a larger branch are joined. Often the collar has wrinkles in it. Cut just past the swollen, wrinkled area and remove the offending branch where it is circular in cross-section.

Many fruit trees send up water sprouts — vigorous new shoots. In their first year they grow straight up and are the thickness of pencils. They should be removed every year. If you cut a bigger branch, you might get several water sprouts surrounding the cut that year — but remove them all next year. Water sprouts are a tree’s attempt to increase food production by making more leaves. Some trees do it vigorously each year, others respond to heavy pruning this spring by growing many this summer. Water sprouts rarely produce fruit — ever.

When I prune fruit trees, I pay attention to the fruit spurs that actually produce the fruit. When choosing which of two branches to remove, I leave the one that will be producing the most fruit. Fruit spurs are 2- to 5-inch branches that have buds on them. Fruit spurs produce both leaves and flowers, and need to be at least two years old for the trees to produce fruit, sometimes longer.

I often get complaints from readers about the fact that their young apple tree has not produced any fruit. Be patient, I say. Each variety of tree has its own schedule — dwarf or semi-dwarf trees produce fruit sooner than full-size trees. A newly planted tree can take two to six years before the first fruits grow. I once had a plum tree that took 20 years to flower and produce fruit, and only did so when I threatened to cut it down if it didn’t produce fruit the next year!

Lastly, know that pruning your tree well will increase the size and improve the flavor of the fruit. It takes a lot of energy to produce fruit, so a tree that only grows 100 apples is better able to feed the fruit and grow the sugars that make it tasty than a tree that grows 1,000 apples. And really, how many apples can you eat?

As to that other March chore, improving the pH of the soil around your lilacs? Two dry quarts of wood ashes or garden lime will sweeten the soil if spread around your lilac. Lilacs do not flower as well in acidic soil, which is what most New Englanders have. It won’t affect this year’s blossoming, but should by next year.

So get outside on a sunny day and get to work. I always find something to do, and pruning is one of my favorite March activities.
