Christmas Wish Lists for Hobby Farmers

Most of us know that chestnuts can be roasted on an open fire, thanks to the opening lyrics of the classic holiday tune, “The Christmas Song.”

But after the holidays, chestnuts seem to be forgotten along with the fruitcake, eggnog and fuzzy socks from Aunt Ida.

One farm in Townsend, Del., is hoping to change the chestnut’s stigma and teach America that chestnuts are not only a delectable treat, but they can be enjoyed throughout the year. Gary and Nancy Petitt probably thought they would be spending their retirement years moving at a leisurely pace with little stress and a light work load.

Instead of slowing down, though, this innovative couple has taken on an entirely new career path with the hopes of rejuvenating a plant species that has nearly been forgotten in the United States.

As owners of Delmarvelous Chestnuts, the Petitts have made it their mission to change the American consumer’s misconceptions of chestnuts as well as to repopulate the country with this fascinating, nut-bearing tree.

To appreciate the significance of the Petitt’s work in the chestnut industry, one must first understand the monumental ecological event that took place in the early 1900s that altered the way chestnuts were perceived. 

History of the Chestnut Tree
Prior to the 20th century, American chestnut trees were among the tallest and most plentiful trees in the forests of the eastern United States.

Gary and Nancy Petitt have taken an entirely new career path–chestnut farming–in their retirement years with the hopes of rejuvenating this nut tree in the United States. The mission of Delmarvelous Farms’ owners is to change the American consumer’s misconception of chestnuts as well as to repopulate the country with this tree. The harvester/sweeper has a special burr-removal mechanism.

When the Europeans first arrived in North America, one-quarter of the trees were American chestnuts.

These massive specimens were commonly over 100 feet tall, with trunks up to seven feet in diameter; they were a necessary food source not only for humans, but also for the wildlife that populated the forests.

Chestnut trees were also used to build houses, furniture and fences. At the turn of the 20th century, a devastating ecological event occurred. Around 1900, a fungus was introduced to America on imported Asian nursery stock that resulted in a chestnut blight.

From 1904 to the 1940s, the blight destroyed 3.5 billion American chestnut trees.

“It was the biggest ecological disaster of that century, at least from a tree point of view,” Nancy Petitt says. “Before the blight, it was said that a squirrel could get on a chestnut tree in Maine and not get down again until Florida.”

According to the American Chestnut Cooperators’ Foundation, “no comparable devastation of a species exists in recorded history.”

With an astounding number of trees suddenly killed in the forests, wildlife diminished because of the lack of food. Farmers and residents of the areas also suffered, with no saleable crops or readily available food source during winter. Chestnuts were quickly forgotten as other food staples were introduced.

The Petitt’s Family Tradition
Not everyone was willing to give up on the hope of chestnuts repopulating the forests, though.

“My husband’s father had a theory that the reason there wasn’t any small game in the woods was because there wasn’t any food for them,” Petitt says.

Since Gary was a child, his father had worked diligently to reintroduce chestnuts to the forest. He worked with the U.S. Forest Service and the Boy Scouts to figure out how to grow the chestnut population. His father’s solution was to introduce Chinese chestnuts, which are resistant to the chestnut blight now found throughout the East, into the woods around his home in northwestern Pennsylvania, creating a viable food source for the wildlife.

Gary’s father’s award-winning work started to repopulate the forests and made an indelible impact on Gary.

When the couple retired from their corporate jobs, Gary’s family background in chestnuts soon started to influence their future plans. Looking for something to do, they thought of buying a small piece of property in Delaware with an eye toward working with chestnuts as Gary’s father had.

In a twist of fate, the Petitts were vacationing in Florida a year later when they read a magazine article about Chestnut Hill Nursery (now named Chestnut Hill Tree Farm) in Alachua, Fla., and its work to blend American and Chinese chestnut trees.

The Petitts were close to the farm and stopped by, where they were generously introduced to much of the research that was taking place in Chestnut Hill Nursery’s effort to re-establish the chestnut industry.

The blending of the American chestnut, prized for its sweet taste though no longer easily found in the Eastern United States, and the blight-resistant Chinese chestnut, with its easy-to-peel skin, was just what the Petitts were searching for.

“We were actually looking for a nut that was commercially viable, while Gary’s dad was just looking for trees that would grow in the forest for the wildlife,” says Petitt.

They bought 500 trees from Chestnut Hill Nursery in 1993 and continued to add more than 1,000 trees over the next two years to their 16 acres of land in Delaware.

This unique combination of two distinct types of chestnuts would prove to be the Petitt’s claim to fame. MORE>>

Firmly attached, they suck until satiated. Only female ticks engorge, swelling hundreds of times their pre- meal weight.

Tick bites are virtually painless. Sensitive individuals sometimes notice when a newly attached tick injects its body fluids but most hosts remain blissfully unaware they’ve been stabbed.

Since ticks neither jump nor fly, to pick up a tick you must brush against one waiting on vegetation to hitch a ride. So don’t venture into tall grass meadows, forests carpeted with leaf litter, brushy terrain or overgrown fields. Stick to wide, cleared pathways and stay in the center of trails. Don’t sit or lie on the ground or on rocky surfaces in tick country.

If you do live in a tick-infested area, or find yourself in one, watch what you wear.

Choose light-colored long-sleeved shirts, long pants and tall socks worn with shoes, not sandals. Tuck your shirttail into your pants and your pant cuffs into your socks.

Find ticks before they attach. Pause frequently to spot check clothing. When they can’t reach skin, ticks migrate north toward your head and neck. As part of spot checks, probe your hairline and behind your ears.

If they evade clothing barriers, they’ll head for tender spots like ankles and behind your knees. You’ll also find them on your tummy where your belt line halts further travel.

Clothing can be treated with Permethrin-based insecticides. Permethrin is highly effective but must never be applied to human skin.

Products containing N, N-Diethyl-3-Methylbenzamide, commonly known as DEET, also repel ticks, although not as effectively as Permethrin. DEET repellents can, however, be applied directly to bare skin.

After tick country outings, carefully inspect yourself, your children and pets, leaving no territory unexplored. Deer-tick nymphs are barely the size of poppy seeds, so you must look close. Ask a friend or spouse to examine your back and neck.

Clothing worn in tick country should be treated to a two-cycle hot water bath or dry-spun in the dryer for at least 20 minutes; otherwise ticks may be lying in wait when you next put them on.

Woods walkers sometimes blunder through an encampment of “seed ticks” (nymphs) and find thousands crawling up their clothing. To remove them quickly, loop a strip of tape around your hand, sticky side out, blot them up, then dispose of the tick-studded tape.

A tick must be attached for about four hours to transmit Rocky Mountain spotted fever; 12 to 24 hours to spread Lyme disease; 24 hours to transfer babesiosis parasites; and 36 to transmit erlichiosis.

If you find a potentially infected tick attached to you, your child or pet, you can possibly prevent disease if you get it off fast.

Wear latex gloves or use a tissue when handling ticks. Tick pickers can catch Lyme disease or Rocky Mountain spotted fever from exposure to tick body fluids.

Don’t touch a match or cigarette to the tick’s backside and don’t swab it with gasoline, cooking oil, fingernail polish remover or petroleum jelly.

And because a tick’s mouthpiece is barbed, not spiraled, you needn’t “unscrew” it during removal.

Folk remedies often irritate the tick and cause it to spit up additional toxins. Besides, most of them plain don’t work.

To remove a tick, use unrasped needle-nose tweezers, a hemostat, or any of the many inexpensive tick removal tools to grasp its mouthpiece, not its body, and pull it slowly and steadily straight out.

Don’t squeeze the tick!
 
If it leaves part of its mouthpiece imbedded in skin, disinfect the area with rubbing alcohol and use a sterile needle to carefully dig it out. Better still, plan a trip to your physician or vet for professional assistance.

Dispatch the tick by dropping it in a container of alcohol, or wrapping it in tissue and flushing down the toilet. Another solution: seal the tick inside a wide strip of tape before crushing it—don’t squash it with your fingernails.
 
When you’re finished, disinfect your tweezers and the bite site with rubbing alcohol and dab on a spot of antibiotic ointment. And if you aren’t certain what kind it is, drop the tick in a vial of alcohol or zip it inside a sealed plastic bag and take it to your vet or physician for possible identification.

Monitor the bite site, watching for secondary infection, abscess formation, or any sign of rash—and try not to scratch!

If an animal is host to a great many ticks, hand picking may be the only logical solution. Armed with latex gloves and a wide-mouth container of alcohol, gently grasp the tick near its head and gently pull it out.

In impromptu situations, step on the tick or crush it between two rocks. Use a fine-tooth flea or louse comb to remove unattached ticks from most any coated animal. And prevent infestation by treating horses and dogs with one of the new, long lasting spot-on insecticides containing Permethrin.

Eliminate farmstead tick habitat by clipping lawns short and keeping barn and outbuilding areas weed and litter free. Discourage favorite tick hosts such as rodents, raccoons and deer by removing food sources and winter shelter.

Chiggers
Chiggers, also called jiggers, redbugs and harvest mites, are among the tiniest of arachnids. Only the microscopic 1/125-inch larvae feed on blood; chigger nymphs and adults don’t bite.

Like ticks, chigger larvae wait on vegetation until a host appears. Once aboard, chiggers head for thin skinned or wrinkled anatomy such as armpits, inside elbows, behind knees, ankles and the human groin.

Chiggers neither burrow beneath skin nor do they suck blood. Instead, when it reaches attractive real estate, a chigger pierces its host’s skin, then injects anticoagulant and an enzyme designed to liquefy skin cells. It sucks liquid and lymph for about four days then drops off, leaving behind a hard red welt with a tiny, hard white center.

The bite itself isn’t painful nor does it itch. However, within a few hours of attachment, the chigger’s saliva causes surrounding tissues to harden, thus forming a hollow, swollen feeding tube called a stylostome. The stylostome itches intensely and the longer the chigger is attached, the deeper the stylostome and the more excruciating the itch.

Chiggers are at their worst around midsummer when daytime temperatures reach 75 to 85 degrees. They’re inactive when the mercury dips below 60 degrees. They prefer damp, shady spots but you can pick up chiggers most anyplace in nature. Besides humans, chigger larvae feed on other mammals, birds, even reptiles and toads.

To avoid chiggers, shun tall grass and similar chigger habitat; don’t sit or lie on the ground, and dress as though you were visiting tick territory.

If exposed to chiggers, take a hot bath or shower, use lots of soap, and scrub yourself dry with a terrycloth towel. Launder contaminated clothing in hot, soapy water for at least 30 minutes.

Because it’s the stylostome that itches, folk cures that call for dabbing chigger bites with nail polish, bleach, alcohol, ammonia or turpentine to kill offending chiggers simply don’t work. Nothing truly salves this itch but time.

Mosquitos
Of the 2,500 or so mosquito species identified worldwide, roughly 200 of them live in North America. Because mosquitoes harbor numerous serious diseases—among them five forms of encephalitis including West Nile virus, dengue, yellow fever, malaria and canine heartworm, they are more than noxious pests.

Like most biting flies, both sexes feed on nectar but only the female drinks blood. She can spot prey up to 110 feet away and is attracted by carbon dioxide and lactic acid emissions, body temperature, dark colors, motion and floral scents. A mosquito requires blood protein to produce eggs, which she lays in marshes, ditches, puddles, slow moving rivers and creeks, lakes and ponds, ornamental pools, stock tanks and horse troughs, buckets, barrels and junk such as cans and old tires. She prefers grass and weed-sheltered stagnant water.

Most North American mosquito species dine an hour or two before, at, and for the same amount of time after dawn and dusk, although a few are strictly day or night feeders.

To avoid being bitten, stay indoors during peak mosquito hours. Wear light-colored, long-sleeved, heavy-duty shirts, pants, socks and hats when venturing outside during mosquito season. Avoid short sleeves, sheer fabrics, sandals and dark colors.
 
Best bets: mosquito-resistant garments like those manufactured by Squito Wear and The Original Bug Shirt Company. Forgo floral-scented personal-care products for the duration of mosquito season, and spray or slather yourself with a favorite insect repellent as often as needed.

Repellents containing DEET work best. The New York State Department of Health suggests adult consumers choose mosquito repellents containing no more than 30 percent DEET. Childrens’ products should contain no more than 10 percent. Higher concentrations don’t work better, they simply last longer.

Less effective alternatives include homemade or commercial products containing oils of citronella or eucalyptus, Avon Skin-So-Soft products, and Bounce dryer sheets wiped on exposed skin or suspended from clothing.

Install mesh screens in your home, keep doors and windows closed, and use mosquito-specific space sprays labeled for household use. But don’t buy a bug zapper; mosquito traps are a better option and don’t fry beneficial light-flying moths.

To best control mosquitoes, eliminate their breeding grounds. If an item holds water and you’re not using it, get rid of it. Dump and refill pet dishes, wading pools, bird baths, livestock watering buckets, horse troughs and stock tanks every two or three days. And drain ornamental pools, puddles, ditches, swamps and other organic water holders or treat them with biological larvicides.

Horse and Deer Flies (Tabanids)
Over 300 species of horse and deer flies, collectively called tabanids, call North America home. Horse flies are the “18 wheelers” of the insect realm, stout bodied and as much as one-and-a-half inches in length. Deer flies are smaller, most the size of common house flies. Only female horse and deer flies feed on blood and they do so by slashing a host’s skin with their sharp mouthpieces.

Most tabanids prefer feeding on horses, cattle and deer. Of the two, deer flies are most likely to bite humans; necks, the backs of hands and ankles are favorite targets. Deer flies’ incessant buzzing and dive bombing canbe every bit as annoying as their painful bites.

Tabanids enjoy warm, sunny days and are attracted by moving objects, warmth, and carbon dioxide emissions. They are day feeders.

Permethrin-based insecticides offer short-term relief to horses and other livestock and can be applied to clothing but not human skin. Other chemical repellents seldom work. Sturdy barrier clothing and Biocontrol Network Consultants’ non-chemical Tred-Not Deer Fly Patches (DETEX 231-832-2323) are best bets for humans afoot in deer-fly country.

Because tabanids are voracious but flighty feeders, often skipping from host to host to complete a meal, they spread many diseases including anthrax, bovine anaplasmosis, hog cholera, Potomac horse fever and equine infectious anemia.

Under sustained tabanid attack, horses and cattle cease grazing and huddle together for protection, resulting in weight loss and reduced milk production. Standard pheromone-baited fly traps won’t attract tabanids but HorsePal Horsefly Traps (Newman Enterprises) are an innovative visual-attractant that will.

Black Flies
Black flies, also called buffalo gnats, are nasty wee cousins of the horse fly. They’re found worldwide, over 1,000 species strong, in boreal to tropical climes.

Like most biting flies, both sexes feed on nectar but the female also drinks blood. Her bite is painfully out of proportion to her size. She slashes and sucks pooled blood like the tabanids, injecting an anticoagulant that triggers mild to severe allergic reactions in most humans. The swelling and itch that follows lasts up to two weeks or more. Hordes of black flies pose a serious threat. Mega-bitten hosts sometimes die from acute toxemia or anaphylactic shock.

Many black flies feed on birds, some on mammals, but a few prefer human blood. The buzzing, dive-bombing, skin-crawling antics of non-biting species coupled with the efforts of those that do, make early spring in forest and lowlands a woods walker’s worst nightmare.

Most black flies are daytime feeders and they rarely venture indoors. Biting varieties target ears, hairline, wrists, ankles and feet. They can’t bite through most fabric but readily burrow under clothing and into hair. DEET repellents are only minimally effective, and nothing works very well. Wear mosquito-barrier clothing and avoid endemic areas if you can.

NO-SEE-UMS
No-see-ums, also called sand flies, sand gnats, punkies and biting midges are among the world’s tiniest biting flies. Most are dark gray or black with spotted wings. Only females suck blood, using the biting flies’ standard slash-and-suck mode to obtain it. Bites are initially painless but within eight to 12 hours, tissues swell and an intense itch sets in.

Most no-see-ums feed at dawn and twilight, from early spring through midsummer. A few species are daytime biters, especially active on damp, cloudy days. Both types frequent salt marshes, sandy barrens, riverbanks and lakes. Chemicals won’t repel them. Because no-see-ums bite through clothing weave, avoid snug shirts and pants. Loose-fitting, light-colored clothing or no-see-um mesh garments work best.

These tiny terrors are highly attracted to dogs and livestock, particularly their ears and lower legs. Gloss painfully chewed areas with a smear of petroleum jelly and keep animals indoors during prime feeding time. Fly masks with ears help protect horses.

Ticks, chiggers and biting flies are among nature’s nastiest creations, yet most can be avoided or controlled with some strategic planning.
