Extension News: April 2008 Archives

These are the days to drink in the precious gold of autumn. As the sun slants low in the sky, the golden hues dazzle us in their brilliance. The black-eyed Susans in the garden flaunt their yellow petals at the wind, which replies by swinging them jauntily in the sunshine. Behind them, tall golden sunflowers nod their huge heads. Each day, the centers expand outward, enveloping the yellow petals until all that’s left are the seeds.

The chipmunks race up the tall stalks to stuff their cheeks with seeds. The chickadees are there too, often hanging upside down as they peck away. A bird releases one seed from its cradle then flies away to crack it open and feast. Are they the birds that have been here all summer long? Or have our birds flown south already and these are migrants from further north, happy to have found a feast to sustain them on their long journey?

Other birds are busy gathering seeds, too. Another flash of gold announces the goldfinch, and soon a small flock of finches is busy eating seedheads around the garden. I watch one bird land on a grass blade nearby and the light stalk sways nearly to the ground. Undeterred, the bird moves along to the very end of the stalk and nibbles on the seed.

The sun dazzles today. It lights up the fading black-eyed Susans and the heavily blooming sunflower stalks, and behind them, the pale gold of clumps of Karl Foerster ornamental grasses. A light breeze is music to the grass, which seems to dance with wild joy.

The goldenrod is buzzing as the bees cover the surface of each cluster of blooms. The bees seem to know that the oncoming cold will soon take the flowers, so they hurry from blossom to blossom. The bees themselves are a golden hue, as are the pouches of pollen on their legs. From sun to flower to bee to pollen, the circle of life itself is represented in the colors of this pigment we humans value so much.

I pick up a fallen maple leaf. The outer edges are a rich, deep red which subtly melds into orange and then gold. In the low sunshine, the colors speak of many things: of spring showers and slowly lengthening days, of the warmth of summer; of cool fall evenings with bright full moons.

On one edge of the leaf, a little grey spider eyes me, then hops to another part of the leaf further away. “Where will you spend the winter?” I ask him. He doesn’t answer, so I put the leaf down where I found it and hope he will survive until spring.

Digging carrots from the garden in 80 degree weather just doesn't seem natural for the end of September. There were a surprising lot of carrots, considering I never got out there to thin them for salad as I’d promised myself I’d do.

So I suffer now. I spent the afternoon in the kitchen processing the carrots for freezing. Now, the non gardeners among you will be thinking “How nice! People out there are still preserving food.”  But the real gardeners will think, “Why doesn't she just put them in the root cellar”?

Well, these carrots needed to be processed because chipmunks or some other critter started eating the carrots at the top and went as far into the ground as possible, leaving a concave depression with all these little tooth marks and making those carrots no good for root cellar storage.

On the other hand, I'm not overly fond of cooked carrots. Thank goodness for my mother's old Farm Journal Cookbooks, which contain recipes from generations of farm wives. They knew how to preserve food: Take 12 pounds of carrots, etc. I wound up with candied ginger carrots and orange glazed carrots. I’ll be very happy this winter to take them out of the freezer.

The beets also needed gathering. Something bigger than a chipmunk had enjoyed the beet greens, and the roots themselves weren't as time consuming to process. I just picked out the ones that were split or nibbled on and cooked them. I stashed the rest away in a cool place to be brought out much later.

As the sun was sinking, I went out to get a few (I thought) beans for dinner. Lugging the full basket back into the house, I set about preparing them. These aren’t just any bean, but scarlet runners. My friend from England introduced me to this heirloom variety. They not only produce the most beautiful red flowers all summer and fall, but the beans themselves taste better than ordinary green beans. They are so beautiful many people grow them just for the flowers and don't even know how good they taste. You have to pick the pods before the beans inside start to swell. If you have to “string” them, they’re too old, fit only for the compost. 

I got them all cut up and didn't have the heart to do any more freezing that day. As my husband walked through the kitchen he casually asked if I was freezing them. I told him, “No, we’re having some hot for dinner and I’ll make the rest into a bean salad that should last the rest of the month.”

While I’m on the subject of heirloom varieties, the Brandywine tomatoes are hitting their full stride. We got them into the ground very late. Most years at this time the plants would be hanging down in the cellar slowly ripening their fruit away from the frosty outside air. Brandywines are so good! No other tomato beats their taste. And big! A couple of years ago I remember picking with pride the first ripe Brandywine. I washed it and sliced three half inch slabs that completely covered the bread for that first tomato/mayo sandwich. This particular tomato was so large I put the rest of it in the fridge and we had it for a salad that evening. I haven't had one that big in awhile, but I did bring one to share with my hiking group today. Everyone tucked slices into their sandwiches except for the one with the peanut butter sandwich. She ate her share separately.

The winter squash are still out there. If nothing has been nibbling on them, they go right into the cold room. No hassle. Thumbing though my gardening magazine, I found a lovely article on horseradish. Something else I’ll need to harvest before too long.

Have you ever tried to process horseradish? Oh, the tears you shed! After my first experience, my mother told me she used to hold the root outside a mostly closed window and grate it out there. Good idea. I'll put my food processor on an extension cord and see how that works.

My mother gave up canning and freezing well before she was my age. She lived though the time when you had to do it to survive the winter. She stopped when they moved off the farm and thought supermarkets were just great. Well, they are, but home grown food tastes better, at least to me. Knowing what went into growing the produce, harvesting it and preserving it for the long winter gives a feeling of security not just because I can have something to eat, but because I still know how to do it. Will the next generation have these skills?

While I love gardening and swimming in the summer, watching the foliage change in the fall, and skiing and snowshoeing in the winter, there's nothing that makes me feel alive quite like the first warm days of spring. A scent calls to me, and I simply must get outside to enjoy the unique aromas of the season.

This corner of New Hampshire was buried under nearly 150 inches of snow this past winter, a record for us. Now, each day I count how many stones in the garden wall are newly visible, which trees are starting to bud out, and how much more brown earth is visible near the dirty piles of snow. Those piles are still high, but they are melting and spring is definitely here.

In one patch of earth, I notice a small flock of juncos feeding. Since they weren't here during the long winter months, I assume they've journeyed from somewhere south of us. They bustle about, finding a few stray seeds scattered by the blue jays, which roil the feeders by suddenly taking off. A robin hops along, searching for something tasty in the ground.

On my walk, I'm serenaded along the way by the red-winged blackbirds. First comes a little bell-like sound and then the wings open, flashing the distinctive red patch, and the head bends down and forward for the big "scree." Three males are dueling furiously. First one sings out and the moment he's finished, a second starts up, followed immediately by a third. Their perches are only a few feet apart. Will they really nest so closely or will one remain victorious while the others leave for new territories?

The common grackles have returned, too. Their brilliant yellow eyes stand out from their lustrous blue-black coats, shining iridescently in the sunlight. Clustering together on a tall tree, they have long and raucous discussions about what? Their recent flights north? The quality of the sunflower seeds at my feeders (duly brought in each night now that the bears are astir)? The depth of snow on the still-frozen swamp? Perhaps they, like me, are simply delighting in the warm spring air.

Nearby, great blue heron couples are choosing their nesting sites. Two of last year's nests are already taken. Refurbished a bit, they're now ready and a heron stands guard over each while the mates are off doing some fishing. Perhaps the first eggs have already been laid. A third nest is being looked over by a pair in mating plumage. They stand on the nest and peer down at it, appearing to ask: What do you think? Will this one do? I call that nest "faraway" because it's off by itself, a short distance from the remaining nests used last summer.

In another tree, two birds stand near a small pile of sticks. I watch while one flies off to a pine and pulls some foliage to spruce up their new home. When it returns, the mate calls out to him before taking the bough and carefully trying it here and then there until just the perfect spot is found. Slowly, the nest takes shape.

Although two more of last year's nests stand empty, the heron activity is far from over. A fifth pair has also chosen a new site for their nest. They've placed few shortish branches in a crotch where two limbs meet the trunk of a long-dead pine. The herons stand one above the other and peer out in different directions over the swamp. I love their looks: plumage flying off the back of the heads, bold orange bills contrasting with the blue-gray feathers.

Nearby I spot yet another pair. They stand side by side in a tree to the south of the others, looking off over the swamp. Last year's five mating couples produced fourteen young; I can hardly wait to see how many six pairs will produce this season.

Meanwhile, one small area of the swamp has freed itself of ice and snow. The opening starts at the beavers' spillway and runs out for perhaps 20 feet. I scan it for ducks, but see none. I know some have returned to the larger lakes and ponds in the surrounding areas. Perhaps soon the swamp will have enough open water to tempt a mallard pair or a beautiful hooded merganser and his mate to fly in for a rest. Or maybe a wood duck couple will discover the nesting box high in the tree on the west side of the swamp.

It's spring. They'll be here soon.

As layers froze over and more fluffy snow arrived, it came to the point that we'd walk a few steps on the snow and then break through and sink to our keesters,occasionally tipping over in the snow. I remember as a child walking to catch a school bus in this fashion. As an adult, I didn't find it nearly so much fun.

Coming nose to nose, so to speak, with the snow forced me to notice I had company: little specks of dirt that actually moved in the clean, fresh snow. This led to further investigation. My online sources told me that instead of minor hallucinations, these tiny, active flecks are one of nature's small miracles: snow fleas. Hardly larger than a grain of pepper, these creatures can survive subzero temperatures, can jump 20 times as high as their body length, and have flourished on this earth since long before the dinosaurs appeared.

I've mentioned these interesting facts to several friends, acquaintances and family members. They had never heard of or seen snow fleas and looked at me strangely as I described the phenomenon I witnessed in the snow. This goes to show, you don't always know what you've got, even when it lives right under your nose.

Members of the insect order Collembola, with more than 6,000 species scattered around the globe, springtails may be the most abundant insects on the planet. The name snow fleas is misleading, as it bears no relationship to fleas.

The springtail gets its name from the spring-like hook (called a furcula) attached to the underside of its abdomen. When these hooks release, the jumping begins. Strangely, however, it may not go anywhere except up and back down in the same position.

Since springtails tend to congregate in large masses and get trapped in crevices and low areas in the snow such as footsteps, watching these tiny guys hopping about can be a bit startling. They will also float in a group on puddles as the snow melts during the day. A non-porous coating on their exoskeletons prevents them from getting soaked.

Springtails don't necessarily appear every day. As this winter progressed, the snowbanks grew to monstrous proportions outside our living room window. It became impossible to ignore them. I began to wonder about a collection of black "dust" that would appear one day and not the next in one corner beneath our eaves. Run-off from our black shingles seemed a possible source, but why one day and not the next? As I was researching springtails it dawned on me that this "dust" didn't come from disintegrating shingles: these black specks were springtails.

Springtails actually have a function in life other than bewildering hapless ladies who have fallen in the snow. They feed on decomposing leaves, fungi, algae, dead worms, insects and other organic debris in the ground. Some sources actually call them most important decomposer organisms in the formation of the earth's soils.

Scientists have also found an unusual anti-freeze protein in springtails' bodies. This protein has been studied to see if it could help increase the longevity of human organs for medical transplants.

Harmless to humans, pets, and structures, snow fleas won't invade your stored food supplies or gnaw holes in your woolens. In most cases, springtails found in or about your house will soon disappear on their own,without the use of pesticides.

Springtails climb from below the snow to the surface as the winter temperatures begin to warm up. I like to think of them as a sign of spring, because they seem to show up when the sun gets stronger. It always pleases me to discover something that can live on and under the snow, defying cold, icy weather.

Somehow I suspect that if life as we know it disappeared from the earth, the tough little springtail would survive. So step outside and see for yourself: Life is where you find it.

The fall precipitation has gotten me to thinking of puffballs and bird’s nest fungus. Autumn weather in New England is always a catalyst for mushrooms, and water may be the most important ingredient.

Fungi are neither plant nor animal, but ancient beings that have made up their own rules. This causes abrupt name changes whenever a mycologist discovers some new chemical contortion or connection. Any habitat with even a dribble of moisture has been colonized by some fungal form and there seems no reproductive method that they haven’t tried.

Hardly a matrix remains unchallenged by the astonishing array of fungal enzymes, and many plants over the millennia have made symbiotic alliances with fungi; some plants, including many orchids, can’t live without them. In trees, wood-decay fungi play a key role in producing beautiful, multicolored patterns in the wood called “spalting,” an embellishment especially prized by woodworkers.

Water may be the only commonality agreed upon by all species of fungi. Water awakens the microscopic, thready hyhpae, which comprise the main body of a fungus. This tangle of threads perforates what we persist in believing is solid ground. In industrious self-employment, these hyphae transform larger things into smaller things. These larger things are as varied as granite, trees, leaves, feathers, insects, shower curtains, and the contents of my refrigerator. The foam in brooks is most often a by-product of aquatic fungi.

Dampness finalizes a fungus’s plan to organize and send forth the familiar mushroom. A particle of evaporated water in an intentionally self-cooled mushroom cap catapults a spore on its journey out of the gill or pore off to a suitably damp new beginning or a desiccated and sorry death. The design is so precise that with all our apparatus we could not duplicate it. Even the shape of a mushroom cap is adapted to allow an appropriate air current to move the spore along its way.

I am thinking in tonight’s rain about more unusual forms of fungus though. The bird’s nest fungi are easy to overlook. Very small, but quite common, they look like groups of quarter-inch cups, leftover dinnerware from some Lilliputian gathering. Each contains a few lentil-shaped “eggs.” These capsules contain the spores, and they are waiting for rain. A well-placed raindrop can propel one of these carriers a surprising distance—up to several yards—which is the point. Offspring must be sent off to fresh food supplies.

Some species of these miniscule nests eject “eggs” trailing sticky threads, which cause these reproductive structures to adhere to any surface they strike. With luck, one of these eggs, called peridioles, will accidentally become part of some herbivore’s meal, eventually left behind somewhere, complete with a ready-to-eat lunch.

Rain is also crucial for the continuation of many kinds of puffballs. Unlike the commonly depicted children’s-book mushroom, puffballs have neither gills nor pores to send their spores aloft. Instead, their reproductive dust matures within the protective sphere, a system that prevents premature drying. Expecting rain, a pre-ordained pore enlarges and opens on the upper surface. A few good smacks of a downpour and puffs of spore erupt into a stiff, damp breeze—perfect for starting more puffball mycelium to continue the process of decay beneath a lawn.

The deluges of this past month have caused puffballs galore on a baseball field I know. They glow in the moonlight like little Halloween ghouls arisen mysteriously from barren turf. Some are large enough for late-season myopic outfielders to prematurely explode them. Enough will have escaped intact, awaiting the rain.

We needed to remeasure the incredible shrinking tree. Last fall, our team of measurers from Hillsborough County went out to measure our national champion sweet birch (called black birch around here). The circumference measurement they submitted was smaller than when the tree was measured in 1988. How could that happen? We had to find out. American Forests, keeper of the National Big Tree List, tries to update its list every 10 years.

I had just taken over the volunteer position of N.H. Big Tree Coordinator. One beautiful day in early spring, Mary Jane Sheldon, who maintains our database, my husband Gordon, and I set out to find the tree. After a sandwich and some map consulting at the New Boston general store, we ended up having to ask some kids where to find the road that would take us to the big black birch.

We stopped at the address given in our records and were met by a lovely woman who came to investigate the commotion caused by her dog’s greeting our team. She directed us to a far corner of her field and told us the tree we were looking for was just inside the woods.

So off across the field we went with our bag of tools: a 100-foot tape measure, the clinometer we use to measure the height of the tree, and the GPS (global positioning system). Trying to find the same tree again after 10 or more years can be difficult. Landmarks change, owners move, phone numbers and addresses get changed. We hoped that GPS coordinates will help solve that problem in the future.

Toward the end of the field we scanned the tree line and saw nothing spectacular. But as soon as we stepped inside the woods and looked to the right as instructed, there it was!

As a novice, I find it difficult to identify the species of big trees because most of the parts used to do it­the leaves, twigs, and buds­are 50 to 100 feet above my head. I was explaining this to UNH Cooperative Extension Forest Resources Educator Phil Auger while taking his Tree Identification workshop, foolishly mentioning that the bark looks the same on all species of big trees. He smiled and said, “That's like telling me the Beetles sound just like Beethoven!”

But this time we knew we’d found our champion birch without needing those identifying clues. It was the biggest tree around. It must have been growing on that stone wall for hundreds of years.

The stone wall turned out to be one of the problems. The tree straddled it. The Big Tree rules specify taking the “circumference at breast height” at about four and a half  feet. “Breast height” was a foot higher on the other side of the tree.

We immediately saw another problem. Picture the trunk of a tree as a human body. The roots are the legs. Where they start to flare out from the trunk is like the hips flaring out from the waist. Then think of a long waist up to where the arms or branches leave the body. This particular tree had normal legs and arms, but it also had two breasts, one in front, one in back!

The two bulges were right where the tape measure should go around. This meant we had to find a spot on the trunk under the bulges and above the root flare. Doing this, we measured 165 inches. Eeeek! Even smaller than the measurement done in the fall. Moving the tape up to include part of the bumps, we got the same 170-inch measurement as the fall team. But the original 182-inch measurement remains a mystery.

Would the smaller measurement eliminate this New Hampshire tree from the National Register? No matter, I had to send the current accurate measurement to American Forests. Months passed before we heard the status of our latest measurement. Finally, in July I got an email stating that the tree is still the largest specimen of its kind in the nation.

The new roster from National Forests will come out in 2008. The Granite State has two other champs and two pending. You can check out the New Hampshire list of Big Trees at www.nhbigtrees.org. Information on the national program is available at www.americanforests.org.

If you know of a big tree, put a tape around it at breast height (watch out for those bumps), and check out our website. If your measurement comes close to the circumference of the current Big Tree of that species, email me at carolyn_page@hotmail.com. P.S. If there is no listing for your county, your tree is an automatic champ!
