Common Name: Winterberry - Genus Species: Ilex verticillata - Family: Aquifoliaceae

Winterberry is a deciduous holly that is native to eastern North America where it typically occurs in swamps, damp thickets, low woods and along ponds and streams. Winterberries are dioecious (separate male and female plants). Only fertilized female flowers will produce the attractive red berries that are the signature of the species.

The attractive bright red fruit of winterberry is eaten by small mammals and more than 48 species of birds. Berries provide considerable impact and interest to the winter landscape. Although

this shrub species is a good provider of wildlife food, its fruits are poisonous to humans.

Winterberry is an erect moderate sized shrub growing to heights of 5 to 15 feet tall. The dense branches of this shrub grow in a zigzag pattern with an upright spreading crown. The twigs are slender, with gray to gray-brown color and small buds. In the wild, it often suckers to form large thickets or colonies.

Elliptic to obovate, toothed dark green leaves (2-3” long) in some years may turn attractive shades of maroon. Relatively inconspicuous, greenish-white flowers appear in the leaf axils in late spring. Flowers, if properly pollinated, give way to a crop of bright red berries (1/4 “diameter) in late summer to fall. Berries are quite showy and will persist throughout the winter and often into early spring. Only fertilized female

flowers will produce the attractive red berries that are the signature of the plant. Generally, one male plant will be sufficient for fertilizing 6-10 female plants. Prune to shape the shrub in early spring just before new growth begins.

Genus name comes from the Latin name Quercus ilex; many shrubs in the genus, Ilex, have evergreen leaves.

Excellent in shrub borders, native plant areas, or bird gardens.

In addition to being a great preservative for beer, Hops (Humulus lupulus) are a fantastic soporific (sleep aid). Sachets or pillows of hops are a popular folk remedy for insomnia. Some stories tell of field workers asleep in the fields after a long day of harvesting because of the powerful sleep-inducing effect. From the weekly newsletter of LandscapeHub

Lunaria- Despite a cage with crossed sticks, the deer nibbled it

away. Currently hiding under a milk crate, in hopes of survival!

September pepper plant is

only 2 ½ feet tall. Note: eaten branches.

When I first talked to Joyce about writing this article, I thought it would be a breeze. I've been growing flowers, fruits, berries and vegetables on the same property for 34 years now. While deer are prevalent,

they've never been an insurmountable problem. I thought I'd go through this summer season to re-test all my deer-proofing methods. I was in for a very rude shock. However, I discovered there are ways to mitigate the damage without resorting to a gun. This year, deer decimated my flower beds and vegetable. Though a resident ground hog may have taken a nibble or two, I believe deer are by far the major culprits. Here is a short list of the crop damage they caused: No corn survived. First planting of green beans was devoured, as were carrot tops. Leaves of squash, cucumber, pumpkin, cantaloupe and watermelon were eaten to the point that the

pumpkins, lopes and watermelon all died before fruiting. Tomato plants were eaten so badly that 30 out of 36 never bore fruit. The remaining six did not bear tomatoes until October. Fifty percent of the pepper plants were “pruned” so severely they died. In the flower beds, everything was fair game, including plants not usually ravaged by deer. Tulips, of course, were nipped in the bud. Mums, lunaria, rudbeckia, shasta and most annuals including marigolds and pansies were eaten. I once had so many lunaria (money plant) that I ripped them out. Now I have one which is in an upside-down milk crate inside of a cage in hopes it will survive. There was one bright spot. While deer ravished all varieties of petunias, they did not care for calibrachoa (million bells). I will plant more of them next year. Here are some methods I used this past summer in my attempt to thwart the little munchers.

1. Mechanical control, which includes caging, covering and fencing.

a. Caging individual plants can work, but if the plant is tasty enough, you'll have to use cages with small 2" x 2" openings. Each cage must be braced with rebar or T-posts pounded deeply into the ground or the deer will press against the cage and wiggle it around so they can nibble tasty leaves. I use the 6-foot metal T-posts, pounded about 6-to-8 inches into the ground. Even with that strong support, some of my four-foot tall tomato cages made of 4” x 4” wire were bent completely out of shape as the “bambits” nibbled as far inside

the cage as they could reach. They had already “pruned” all branches which extend beyond the cage.

September tomato- too short to stake or cage due to browsing.

b. Floating row covers can be used on rows or beds. Deer netting will work when thrown over berry bushes. You may have to check both regularly to make sure the deer haven’t “adjusted” them to enable a little extra nibbling. Our strawberries are planted on a hill behind the house and have never been bothered by deer – until this year. Thankfully, it was post-harvest when they pruned all the leaves – right down to the crowns in July. I put row covers over as much area as possible and the plants have

successfully begun to grow back. Even though I have spread the daughters out, you can still see in the photos how sparse the outside of the beds are where the row covers did not reach.

c. I have also used snow fencing, but quickly discovered the deer will jump in and out if there's too much space between sides of the fenced area. Deer can clear a 4' fence from a standstill. The trick is to deceive them by leaning the fence at an angle, so it looks wide as well as tall or by spacing the sides of the protected area close together. For my green beans, I placed the fencing about 12” apart. It was challenging to harvest the beans and I was able to harvest a healthy, bountiful second planting of beans.

A plain rope fence strung from T-posts or rebar can work, especially if you hang bright reflective aluminum pie pans every few feet. Some people swear deer dislike anything white. They use white plastic ribbon strung about 3' off the ground...that's eye level for browsing deer. Experiment with heights. Maybe using the rope on top and the white ribbon below would create enough confusion to discourage curious deer.

I have used solar-powered red lights that blink at night. I have found them effective only if you change their position and location about once every other week or so. This winter I’ll be testing the effectiveness of solar-powered motion-sensitive lights to discourage night-time browsing.

2) Spray remedies such as eggs or milk can be used as a deterrent. I've used such mixes on tulips and lilies (oriental, stargazer and daylily) with great success. I was so frustrated toward the end of the season to use it on select pepper and tomato plants. Surprisingly, it worked there also. The spray does not need to be re-applied every time it rains, but occasionally resprayed to accommodate plant growth. The two recipes I’ve tried are included below.

A naturalist friend, Ms. Hood, suggested dusting dry or powdered milk onto the soil over freshly planted bulbs. I plan to modify that slightly by adding hot pepper flakes. Hopefully it will also discourage squirrels.

Watching the destruction of my gardens this summer, I wondered why the deer were so invasive this year. That’s the key word: invasive. My theory is that so much of their natural habitat has been overtaken by unpalatable invasive species that the deer really have little to eat in the wild. Japanese stilt grass is everywhere in the woods and has choked out native grasses. Maybe the deer are turning to my garden for “comfort food.” Following is a “deer-deterrent” spray I’ve used with good results:

Blueberry bed 15’X15’ enclosed by snow fencing. It’s an experiment. Will deer jump into a small area?

They can, but will they?

Right side of strawberry bed had row cover. Notice

closeness of my house.

Home Remedy Deer Repellent 1 egg OR 1-2 cups of milk ½ cup milk 1 gallon of hot water 1 Tablespoon each cooking oil, dish soap 1-2 Tablespoons garlic powder 1 gallon hot water 1-2 Tablespoons hot sauce (optional)

As a last resort, I have been told that feeding the deer in a location away from the gardens, especially in winter, may redirect them to that location. For example, throw some corn or apples along a wooded perimeter or fence line. I tried that two winters ago and had less damage. I will definitely try it again this winter. If it works again, I’ll feed them all year long. It’s cheaper than feeding them in my vegetable garden and flower bed!

Re-examination of Autumn Olive Shrubs: subterranean immunology Elaeagnus umbellata, commonly known as Autumn Olive, is considered to be

an invasive, non-native species on the American continent. This shrub is native to Eurasia and was brought to North America in 1830 for the purposes of preventing erosion of un-vegetated dry, sandy soils with low-pH and as a wildlife attractant. In the 1940s the U.S. Soil Conservation Service advised the planting of Autumn Olive as windbreaks and to stabilize strip mine soil. According to the Michigan Department of Natural Resources Autumn Olive provides a winter food source in the form of lycopene rich berries to a variety of songbirds such as thrushes, cardinals, Cedar waxwings, Evening Grosbeak, sparrows, Bobwhite, Ruffed grouse, Ring-necked Pheasants, wild turkeys, and Mallards. When flowering this plant provides nectar to Ruby-Throated Hummingbirds and Sphinx Moths and provides nesting

habitat and protective cover for songbirds. The University of West Virginia Extension Service details this shrub as a food source for upland game birds, two migratory game birds, twenty non-game birds, and four mammals. In contrast, the Missouri Department of Conservation states that Autumn Olive is an invasive shrub that “degrades native wildlife habitat” and recommends chemical control

with the herbicides 2,4-D, dicamba, or a 50/50 mix of triclopyr and diesel fuel. This conflicting information entreats one to investigate further the role of this plant in our local

environment. This shrub represents a complex symbiotic relationship below ground as well as above, which involves this plant, nitrogen fixing gram positive, aerobic Frankia actinomycetes, and aerobic arbuscular mycorrhiza belonging to phylum Glomeromycota. In fact, with further examination, one can see that this plant represents a complex beneficial triad of symbiotic organisms, the products of which may benefit humanity both directly and indirectly.

The Larry Franz Woodland Walk at Liriodendron (aka Lirio) has been a Master Gardener project since 1997. It was established by Master Gardener Joyce Humbert (Class of 1997). Back then, there were very few Harford County MG’s – 29. But the garden project was enthusiastically accepted. MG Jerry Hudgens was exceptionally helpful recommending hardy and durable native plants and ferns. After Joyce Humbert became less active, in 2003 I took over. Adding plants is top priority. There are over 230 plants/shrubs and 30 ferns. Another priority is providing an educational aspect by having plant labels and an educational brochure in the mailbox. The garden is rustic and unlike one you would find at Longwood Gardens. Despite the deer, who decide what we plant, the garden is very active. Many Master Gardeners are not aware of the Larry Franz history, beauty, and support needs. Nestled within the woodland area behind the mansion the hidden location even hides from our MG workers. Participation has been in decline. It is a short walk to the garden when you park at the Mansion, walk left of the porch and follow the Larry Franz Woodland Walk signs. Lirio garden’s biggest need is for 5 or 6 more volunteers every week. If you decide to volunteer, the happy work (both easy and somewhat harder) occurs every Tuesday at 9 am starting in April. April is the best time as the spring ephemerals are blooming. Volunteers bring gloves, their favorite weeding tool, kneeling pad, and drinking water. Lirio has garden carts and larger tools. Weeding is the biggest task all year long. Sorry, I have no control over weeds and deer, but suggestions are always welcome! A bonus: every workday is also educational! We always take time to learn about the plants, especially those in bloom. Most sessions wrap up by 12 pm. Lirio volunteers usually earn approximately 2 hours of volunteer time. And sometimes one hour of education. The rain policy is difficult to determine since it doesn’t always rain in the same places in Harford County. Best if you text or call me at 410-652-1338 prior to 8:30 am. If you want to know why the garden is called the Larry Franz Woodland Walk, come volunteer and you’ll learn!

Human ears can’t hear them, but other plants or animals might By Katherine J. Wu, smithsonian.com, December 9, 2019 https://www.smithsonianmag.com/smart-news/scientists-record-stressed-out-plants-emitting-ultrasonic-squeals-180973716/

If a drought-parched plant lets out a scream, but it’s at a frequency too high to hear, does it count as a cry of distress? According to a study posted on the preprint server bioRxiv last week, the answer could very well be yes. (And we’re not talking about folkloric mandrakes.)

Do Plants Make Ultrasonic Squeals When Stressed?

For the first time, researchers appear to have evidence that, like animals, plants can audibly vocalize their agony when deprived of water or forced to endure bodily harm. The study, which has yet to be published in a peer-reviewed scientific journal, adds another dimension to scientists’ growing understanding of how plants detect and interact with their surroundings—despite lacking many of the sensory organs their faunal counterparts deploy.

In recent years, it’s become abundantly clear that plants are far more sensitive than researchers once gave them credit for. They respond when touched by insects, turn toward sources of light, and some even sniff out other plants. Others are even sensitive to anesthetics, suggesting that they’re capable of experiencing something akin to “pain.”

“Plants are not just robotic, stimulus-response devices,” Frantisek Baluska of the University of Bonn in Germany told Joanna Klein at the New York Times last year. “They’re living organisms which have their own problems.”

Actually, making that anguish audible, however, is another matter entirely. To test that possibility, a team led by Itzhak Khait, a plant scientist at Tel Aviv University in Israel, placed microphones capable of detecting ultrasonic frequencies four inches from tomato and tobacco plants, then either stopped watering them or snipped their stems.

Measuring in the range of 20 to 150 kilohertz, the researchers found that even happy, healthy plants made the occasional noise. But when cut, tobacco plants emitted an average of 15 sounds within an hour of being cut, while tomato plants produced 25 sounds. Stress from drought—brought on by up to ten days without water—elicited about 11 squeals per hour from the tobacco plants, and about 35 from the tomato plants.

The shrieks were also surprisingly informative. When the team fed the recordings into a machine learning model, it was able to use the sounds’ intensity and frequency distinguish whether they were related to dryness or physical harm, or were just regular, day-to-day chatter. One odd pattern? Thirsty tobacco makes a bigger ruckus than tobacco that’s been snipped, reports Adam Vaughan at New Scientist.

Researchers aren't yet sure how plants produce these sounds, but Khait and his colleagues propose one possibility in their paper. As water travels through the plants’ xylem tubes, which help keep them hydrated, air bubbles will form and explode, generating small vibrations. Previous studies have picked up these waves, but only through devices attached directly to plants. Still, the process, called cavitation, could explain longer-range sound production as well, as Edward Farmer, a plant biologist at the University of Lausanne in Switzerland who wasn’t involved in the study, tells Vaughan. But Farmer also remains cautious about the recordings, which may have picked up ambient noise as well. Even drying soil can produce faint sounds, reports Nicolette Lanese for Live Science.

All this stress-induced “screaming” wasn’t in a range detectable by human ears. But organisms that can hear ultrasonic frequencies—like mice, bats or perhaps other plants—could hear the plants' cries from as far as 15 feet away.

It’s not yet clear how ubiquitous stressed squeals are among plants, though the researchers have started to listen in on some other species. Plants also experience many kinds of stress, such as those brought on by extreme temperatures or salinity, and may not always react in the same way,

Microphones picked up ultrasonic sounds produced when tomato or tobacco plants were cut or dried out. (joffi / Pixabay by CC0)

Anne Visscher, a plant biologist at the Royal Botanic Gardens in the United Kingdom who wasn’t involved in the study, told Vaughan. And any ideas on what purpose the sounds might serve—from warning other plants to passing information onto animals—remains speculative, she adds.

For now, it’s useful to simply know what plants are truly capable of. Something to chew on, perhaps, the next time you’re pruning your tomato plants.
