Leaflet - January 2012
A Letter from the Executive Director

Dear Friends,

Happy New Year! I hope this message finds you in good health, and looking forward to planning and planting your garden this spring.

At Mass Hort we are busy organizing horticultural activities for 2012 in our gardens at Elm Bank, at the Blooms exhibit at the Boston Flower and Garden Show, and through our educational programs. Our resolution in the New Year is to create more opportunities for you to connect with our large community of horticultural and gardening enthusiasts: people who enjoy gardening, spending time outdoors, and who tend plants for aesthetic pleasure or culinary delight.

The Boston Flower and Garden Show is just around the corner (March 14-18), and Blooms volunteers are busy getting ready for the show. The Garden to Table program is gearing up for lectures to inspire people to design and plant their spring vegetable gardens.

"The Gardener's Fair at Elm Bank" will take place on May 20th, selling spring plants, garden equipment, hardscape, and décor -everything you need to get ready for the season and make your home garden a place of beauty. Society Row plant experts and White Flower Farm, with a variety of tomatoes, are just some of the many vendors you will find at the fair. Meanwhile, our education department is busy connecting horticultural curriculum to schools and camps so more children can learn about plants and the natural world.

I have had a wonderful first year as the Executive Director of Mass Hort - full of challenges, opportunities, new friends and business partners, and constant learning. I am deeply indebted to Mass Hort's Board of Trustees and staff, who have worked tirelessly over the past several years to ensure Mass Hort continues its 183-year legacy.

Our programs are only possible because of the generous support of our donors, members, and sponsors, and the hard work of our staff, volunteers, and our Board of Trustees. Thank you for your continued support of Mass Hort as we work to ensure the future of horticulture by engaging the public in this beautiful science.

Warm regards,
Katherine K. Macdonald
President/Executive Director

 
Winter at Elm Bank
Hellebores in Winter 2011
Hellebores in Winter

Looking for a brisk walk through a beautiful space? Come to Elm Bank. Yes, the massive stands of annuals and perennials are a memory, but now is when garden 'structure' comes to the fore in places like the Bressingham and Weezie's gardens.

And, if you look carefully, there are flowers or winter branches that become invisible during the other seasons. Winter Flame dogwood (cornus sanguinea 'Winter Flame') is a pleasant but unremarkable shrub with medium green leaves and an insignificant flower during the summer. But when the leaves fall and the plant is hit by a hard frost, orange-red branches that seem almost on fire emerge. You can see multiple specimens of this wonderful shrub in the Bressingham Garden.

Winter heather

You'll also find winter-blooming heathers (calluna vulgaris) around Elm Bank; their striking pink or purple flowers are low to the ground, framing rocks. And, look closely and you'll find clutches of winter-blooming hellebores (Helleborus) around the gardens. These durable plants will eventually be covered by a foot of snow but, when as soon as it melts, those flowers will not only be present, they'll have multiplied.

So, come see us, and keep a sharp eye out for the more subtle beauty at Mass Hort.

 
Growing Your Plants for the Flower Show

The Boston Flower & Garden Show opens in ten weeks, which may seem like an eternity as winter bears down, but not if you're contemplating entering a plant in the Amateur Horticulture competition. Now is the time to start getting your plant ready for the show. What follows is also an excellent guide to caring for any houseplant that you want to keep at its best.

By now, you've already decided what plant or plants you think will shine for the flower show. You know where you are growing them --in a window, under artificial lights or in a greenhouse. You've decided how you think they should look when entry day arrives. Which all means that now is when you start working toward that look.

Watering is one of the first areas where problems can arise. Keeping a plant properly watered during the winter months in New England requires taking into account the plant's water needs based on many variables. Is it growing in a window with the still-limited light of early winter? Or is it under artificial lights getting the light that it grows best in? Is it in a house made dry by central heating, or a greenhouse where you can control the humidity? Under-watering is quickly and easily spotted (and corrected). Overwatering is often not noticed until the plant is seriously affected.

Brown tips may be a result of over-watering
Brown tips may be a result of over-watering.
One frequently seen problem is brown tips on leaves. It's often a symptom of overwatering, but it can also be a sign of too much fertilizer, using 'softened" water or dry air.

Here's how to determine what's causing your plant's brown tips: first, make certain you know how much water the plant wants. Use a trusted houseplant guide book to determine whether your plant likes soil that dries out between watering, is just barely damp or always wet. Check with your finger before watering for an instant read. Remember that clay pots dry out much faster than plastic or glazed ceramic and adjust your schedule accordingly. Always water until water comes out of the drainage holes freely, ensuring the soil is wetted through and accumulated salts are flushed out. Never let the plant sit in a saucerful of water.

Fertilize carefully to avoid the build-up of salts in the pot. The amount of fertilizer that a plant needs, or can use, is based on the type of plant, the time of year, the amount of light it receives and so forth. Again, know what your plant needs and avoid one-size-fits-all gardening.

If your home has a water softener, use distilled water to eliminate the salts from your plant's diet. One common contaminant can be substantially reduced by simply allowing the container of water to sit, uncovered, overnight; the chlorine will evaporate.

Humidity can be increased by misting plants daily or keeping plants together in a group. Setting pots on a bed of pebbles just above the water level provides continuous humidity.

Trimming diseased leaves now will leave plenty of time for new growth before spring
Trimming diseased leaves now will leave plenty of time for new growth before spring.
Cleanliness is a great way to keep problems from building up. Washing the plant leaves under a sink sprayer also gives you a chance to check for any problems. Washing eliminates not just dust on the leaves but also bugs before their numbers rise to the point of damaging the plants.

Not all bugs are bad bugs. Some are harmless visitors, some are carnivores who will eat aphids, mites and other vegetarians. Don't run for the pesticide sprayer until you are certain that what you see is a danger to your plant. And then use the safest method possible, a soapy water bath, a dilute alcohol spray or a Q-tip cleaning. Frequent inspection means you find the problem while it is easily handled.

You should also be starting to groom the plant for shape and size. Branches growing in a way that makes the plant unbalanced may need to be trimmed back. Never neglect removing dying or damages leaves. Healthy new leaves will usually appear quickly. If you wait to do all the grooming just before the show, your plants will not show at their best.

You've got ten weeks to make your plant a blue ribbon winner. Use them wisely and you'll have houseplants that will look good not just for a few days in March, but all spring as well.

How a Festival Tree Came to Be, and How It Found a Home

Loretta Carrigan loves the ocean. She never misses an opportunity to go there and that love is shared by her husband, Mark, and their children. But last year Loretta, who by day runs the floral department for an area supermarket, yielded to her children's demands and she created a tree for the Festival of Trees based on Hot Wheels cars.

Loretta Carrigan of Medfield crafted a tree that shares her love of the sea
Loretta Carrigan of Medfield crafted a tree that shares her love of the sea.
The tree was a hit, but Loretta made a promise to herself that this year's tree would be all about her first love. And so she put her considerable creative energies to work decorating 'The Sea, My Favorite Place to Be' for the 2011 edition of the Massachusetts Horticultural Society Festival of Trees.

She found tree lights in the shape of lobsters, collected sand dollars and starfish and unusual shells which she hand-crafted into ornaments. She found an iridescent garland that seemed to be made of mother-of-pearl. Around the base she placed books on shells and a Nantucket basket.

Her tree was, in the words of Mass Hort Trustee Gretel Anspach, "a ticket magnet." People who come to the Festival of Trees can purchase sheets of raffle tickets to put in stanchions next to their favorite tree. One of Gretel's responsibilities with the Festival is tallying how many tickets each tree attracted, and Loretta's tree collected nearly 600 tickets.

Winners of 'The Sea - My Favorite Place to Be'
Andrew and Christine, winners of
'The Sea - My Favorite Place to Be'.
Enter Christine and Andrew. The Framingham couple learned about the Festival of Trees from an on-line posting. The idea of seeing decorated trees in a horticultural society setting piqued their interest.

"When we got into the Hunnewell Carriage House, we were overwhelmed by the beauty," Andrew says. "It was clear that a lot of work had been put into the trees' decorations."

Andrew and Christine made several trips around the room and settled on five trees that they especially liked. They bought sheets of lottery tickets and parceled them out among their favorites.

"We were drawn to 'The Sea, My Favorite Place to Be' by the overwhelmingly intricate and detailed ornaments and lights," Andrew says. "We are huge fans of the sea and appreciated the aesthetics of the ocean theme."

On the evening of Saturday, December 10, their phone rang, telling them they had won a tree, which they collected Sunday morning.

"We got the tree home and set it up in our living room," Andrew says. "Everyone who either saw the tree in person or via pictures we emailed remarked on its beauty and color. They especially loved the handmade shell ornaments and the lobster lights! We made certain everyone knew it originated at the Festival of Trees."

Christine and Andrew plan to display the tree in their home again this year. They'll also be back at the Festival of Trees.

Who knows? Maybe lightning will strike twice.

 
Flower Show tickets make a special gift

The gift of a membership in the Massachusetts Horticultural Society is a year-long invitation to discover, save and to appreciate. It's a gift that won't soon be forgotten.

MassHort Membership BrochureIn March, you'll be sending them to the 2012 Boston Flower & Garden Show for free. Next month they can enjoy an Amaryllis or a pot of paperwhites for indoor forcing with a $25 Gift Certificate from White Flower Farm. Through the winter they'll receive Organic Gardening and Garden Design magazines to let them plan for spring. Next spring they can explore Elm Bank's many gardens and even its extensive library.

In addition to these tangible things, there's an underlying gift that goes beyond anything that can be tied with a bow: the knowledge that they're supporting horticultural education. They're helping children's programs in Weezie's Garden and amateur horticulture at the flower show. And, they're helping to preserve and maintain Elm Bank, one of the great educational 'teaching gardens'.

Mass Hort's Special Gift Membership Offer

Membership is a terrific gift. And, if the recipient has never been a Mass Hort member before, it's an even more attractively priced one.

To introduce new people to the Society, we'll take $15 from the price of an individual or a family membership. That makes the gift of an individual membership just $35; a family membership just $70.

By using our online Gift Membership order form, you can personalize your gift by including a special message to your recipient. For more information, visit our Gift Membership section.

 
Mass Hort Forms a Book Discussion Group

On Wednesday, January 18, the Library of the Massachusetts Horticultural Society will hold the first session of a monthly, gardens and gardening-themed book discussion group.

Called 'Telling Garden Tales', the group will meet from 10:30 a.m. until noon in the Board Room of the Education Building. Its purpose is to encourage participants to read the works of talented authors and to share their thoughts about the books with new friends. Founder Maureen Horn's hope is that, at future meetings, the group will discuss fiction and non-fiction books that are concerned with gardens, plants, and the land.

"Because of the interest in the literature of Eudora Welty generated by Jane Roy Brown's lecture on her book, One Writer's Garden, which studies how Welty reflected the care and love of her gardens in her short stories, it seemed fitting that we look at the stories themselves," Maureen says. "The book chosen to inaugurate the club series is The Collected Stories of Eudora Welty, which is available in all Minuteman Library Network public libraries, so there shouldn't be a problem in borrowing it."

Because the initial meeting is just two weeks away, the first assignment will focus on just one story, "A Curtain of Green". "But it may be hard to resist delving further into the book," Maureen says.

Jane Roy Brown notes in One Writer's Garden, was that Eudora Welty's favorite flower was the camellia, and attendees at the session will be put in the proper mood when they enter the Education Building, where camellias are blooming at the entrance.

A small donation to help pay for light refreshments will be appreciated. The discussion group will be limited to twelve participants. To sign up for this first session or to indicate your interest in subsequent meeting, please call or Mass Hort Librarian Maureen Horn at 617-933-4912 or This e-mail address is being protected from spam bots, you need JavaScript enabled to view it .

 
The Green Garden
The Green Garden by Ellen Sousa

The Green Garden : A New England Guide to Planning, Planting, and Maintaining the Eco-Friendly Habitat,

Ellen Sousa (Bunker Hill Publishing, 2011)

Reviewed by Maureen Horn, Mass Hort Librarian

What makes a 'green' garden? Aren't all gardens 'green' by definition? Ellen Sousa has some strongly held and eloquently stated views that an 'eco-friendly' and 'beneficial' habitat is essential to our long-term environmental well being. She has written a book that is specific to New England that tells how to create such a garden.

Ms. Sousa sets a high but reasonable threshold for her gardens; namely, that they must be sustainable for enjoyment by future generations. They should be beneficial in that they attract the animals and insects that were indigenous to our area before European settlement. Her goal is to gradually reverse the missteps made over a period of centuries. She acknowledges that doing so takes hard work, but that it can be done in small, manageable steps.

The steps are easy at the beginning, such as introducing durable native plants like violets and goldenrod. Surprisingly, Ms. Sousa is not opposed to growing non-native species provided they aren't potentially invasive. Japanese crabapples, for example, don't push their neighbors out of the way. Moreover, they attract butterflies and hummingbirds. Above all, though, she wants us to enjoy our gardens. To help us appreciate them, Ms. Sousa has filled her book with gorgeous photographs paired with the words of noted writers.

Her steps to creating a garden start with having a vision of the final result. That, in turn, takes careful preparation and she believes a great way of planning a habitat landscape is to take a tour of the neighborhood. The Green Garden points out what to look for during the tour in order to identify what plants and animals are already thriving there.

Some books on eco-gardening can become shrill when discussing what is 'allowed' and what is not. Many of those books also adopt a 'this way or not at all' attitude. Ms. Sousa doesn't fall into this category. Instead of idealizing the potential habitat gardener, she recognizes that many of us may have misgivings about inviting what we call pests into our sanctuaries.

For example, knowing that insects are not usually the favorite life forms of many people, she motivates us to attract them by giving examples of how they are necessary to most birds. She knows that not all wildlife is welcome in our garden and gives advice on how ways to discourage or distract certain animals. Never forgetting that attracting wildlife is the main goal of the habitat gardener, though, she mandates what is needed to attract moving creatures in a chapter called, "Habitat Essentials".

The book is generous with lists of plants for every kind of soil and amount of sunlight. Far from focusing on just the suburban gardener, Ms. Sousa spreads her advice all around New England, helping the reader to manage forests and farms, to landscape near the shoreline and near freshwater ponds, streams and other wetlands, and to plant in small spaces, for example, on rooftops.

The author knows that hope and hard work are important, but that knowledge is more important. We look forward to hearing Ellen Sousa during a lecture in mid-spring. Reading the book ahead of time should act as a catalyst to enlightened questions.

 
January Horticultural Hints

by Betty Sanders
Lifetime Master Gardener

Think Snow! Gardeners should join skiers now in praying for snow. The bare ground leaves our perennials (and any newly planted trees and shrubs) vulnerable to the freeze and thaw cycle. Without a blanket of snow to keep the ground cold, every warm day that follows a cold night includes the possibility of pushing plant roots up and out of the soil, exposing them to drying winds and freezing temperatures the following night. Cold weather doesn't kill hardy perennials: warm days in winter can. Your Christmas tree is a great source of branches to shade perennial roots from the sun. You can also provide protection to plants with a layer of mulch, compost or chopped leaves. The only good news in the December weather is that heavy rains ensured evergreens a good supply of water as they sunbathe their way into winter.

Branches from our Christmas Tree will help shelter perennials from freeze-thaw cycles
Branches from our Christmas Tree will help shelter perennials from freeze-thaw cycles.
When we get snow , be careful removing it from walks and driveways. Never throw snow on shrubs or the branches of trees. Gently brush snow off laden branches to help the plant return to its natural form. Try to shovel your way out of the house. Footsteps or tire tracks in even light fluffy snow will create patches of ice where the snow is compacted. Getting rid of ice is more difficult and even more dangerous to your plants. Remember that ice salts do not work instantly. Use minimum amounts of ice melting salts and wait to see if the resulting melt allows you to shovel up the remainder. And don't apply salts when it is too cold for them to work. Calcium chloride is only useful to 15 degrees. The newer ice melts stop working at 5 degrees. Salts will damage both the leaves and needles of plants it lands on, (think about all the dying pines along Routes 128 and 495) and the roots as it seeps into the ground. Where possible use alternatives such as sand or cat litter that will disappear into the garden or lawn in the spring.

Winter moths dancing around your lights in December are not a happy sight-you are probably facing an infestation of winter moth caterpillars in the spring. When they hatch in early Spring - anytime between late March and mid April - the small green caterpillars will tunnel into the leaf buds of oaks, maples, fruit trees and many others. They leave the tree weakened, requiring it to produce a second set of leaves. Most trees can survive one or even two years of this, but eventually the repeated stress will kill them. You can spray small trees now with dormant oil (on days when the temperature is above 45 and no hard frost predicted that night) to smother the egg masses. When the caterpillars hatch a biological product based on spinosad is the best control. For large trees, call an arborist, particularly if your trees suffered last year. (For a longer article on winter moths, click here)

Spraying with a commercial mixture of putrefied eggs and garlic will help deter deer from eating shrubs' buds
Spray-on commercial deer repellents smell awful for a few hours. They're best applied wearing old clothes.
Spray your plants to save them . Winter is cruel to our plants. Harsh winds dry the leaves of the evergreens and hungry deer, rabbits and other varmints will eat almost anything they find. On warm dry days, you can spray evergreens with an anti-dessicant such as Wilt-pruf that helps the leaves and needles retain moisture. A monthly spraying on another warm day with an animal repellent may prevent leaves and flower buds from disappearing into the stomachs of browsers.

Cyclamen Rescue. First, not all holiday gift plants will be long-lived houseplants. Poinsettias take the patience of Job to re-bloom, amaryllis need at least a year to repeat their glory. But cyclamen can be perennial pleasers. We have one plant that has been with us now for 15 years. It may look ragged at times, but it blooms faithfully every winter.

Cyclamen
Cyclamen.
The cyclamen that came into your home was raised in a greenhouse. It was given carefully controlled daily doses of water and fertilizer. Temperatures are adjusted to encourage the optimum growth and artificial lights provide for optimum light for blooming. Then we bring them into our homes where the air is painfully dry from central heating, the light on the table where reside or the mantel they decorate is not likely to be what they have grown used to. So don't be surprised when your beautiful specimen suddenly has yellow leaves and drooping flowers, and don't throw it out. Cut off dead and dying leaves, it had more than it can possibly support in its new home. Place it in the coolest room in the house, even the basement if it can sit next to a window. Cut back watering to once a week. The dying should stop in a couple of weeks and then you may see new leaves or even flower buds. Return it to hot rooms for only short periods of time. In the spring, set it outside in a well shaded location (ours summer under rhododendrons) and return it to the house in the fall. You may well be celebrating Christmas 2012 with it in a place of honor again.

The Winter That Hasn't Been

by Neal Sanders
Leaflet Contributor

On the second day of this new year, I plunged into the woods that make up part of our property and sawed a very large tree limb into roughly a dozen pieces. The limb - more accurately, about a third of a tree - fell during our brush with Irene back in late August, and we have a policy that "what falls in the woods stays in the woods" unless it interferes with the sight lines from one of our windows.

I will freely admit that when we first noticed the limb, I made some kind of vague commitment that I would "do something about it, eventually", which is commonly understood to mean that it will still be on my "to do" list in 2030.

That's me on December 27, 2010
That's me on December 27, 2010.
For me, the saving grace of most such promises is the advent of winter. Once there's a foot of snow on the ground, outdoor chores are reduced to one or two bouts of cutting firewood. The wonderful thing about a good, old-fashioned New England winter is that five months of Mother Nature acting on something as ephemeral as a tree limb eliminates the problem without me having to break a sweat. Come next spring, the problem would have mostly solved itself.

But this is - at least so far - the snowless winter, except for a cruel October storm that raised all sorts of false hopes about record snowfalls (and left much of New England without power for a week). All the autumn chores that I put off with the full expectation of getting a pardon once the snow pack was knee deep are still out there, beckoning me. Instead of curling up with a book on New Year's Day, I spent an hour cutting down the ornamental grasses that should, by all rights, have been flattened by now. This is patently unfair.

And, if you remember back just one year, we all spent the week between Christmas and New Years digging out from a pair of back-to-back storms that dumped nearly three feet of the white stuff across the region. Once that snow was in the record books, all I had to do was point to the snow banks and wince a little bit about having pulled a muscle wielding our snow blower, and I was excused from all chores. I got a lot of reading (and writing) done last winter.

This year I walk out to the mailbox and see the pile of branches that really needs to get taken to the town dump. Out back, there is a mat of leaves on walkways that ought to get raked so that moisture can better seep down into the ground. The list of uncompleted autumn chores is endless.

Somewhere out there is an Alberta Clipper that is going to merge with some warm, muggy moisture from the Gulf of Mexico. They're going to collide somewhere over Pennsylvania and shoot northeast. When that happens, we're going to get buried. I, for one, can't wait.
