Thomas Christopher | Nature Into Art – Lessons To Be Learned From the Gardens of Wave Hill | April 10, 2022

The gardens of New York City public garden Wave Hill are celebrated worldwide; Thomas Christopher has followed their development since he was a horticultural student at the New York Botanical Garden in the mid 1970’s. In 2017-2018 he spent a year joining the gardeners of Wave Hill in their daily routines, studying the techniques and concepts that could be translated to the home garden. Join him for a tour of Ngoc Minh Ngo’s award-winning photographs of Wave Hill and an exploration of how this landscape’s lessons can inform your own horticultural ventures.

If he’s not planting or pruning, Tom Christopher is probably in the WESU FM radio studio, working on his weekly program and podcast, Growing Greener. Each week, Tom brings listeners an interview with one of the leading voices of gardening with nature – the goal is to make your landscape healthier, more beautiful, more sustainable, and more fun. Growing Greener currently broadcasts on a dozen radio stations and downloads as a podcast to 5,000 listeners a month.

Tom is also the author of 16 books about gardening, most recently Nature Into Art, a celebration of Wave Hill, New York City’s ground-breaking public garden, and the lessons it has to offer to gardeners everywhere. He also writes a syndicated weekly gardening column that appears in newspapers throughout central New England and upstate New York.

Outside the garden, Tom’s interests extend to stone wall building and making vintage hard cider every fall from heirloom apples with his wife Suzanne. A long-time resident of Middletown, CT, he gardens there and, on the weekends, in the Berkshire Hills of western Massachusetts.

Nicholas Dorian | The Secret Life of Wild Bees | April 7, 2022

You’ve probably heard “save the bees!” as news reports of insect declines flood the media. But do you know which bees need saving? Over 4000 species of bees inhabit North America, and most of them don’t live in hives or make honey. In this lecture, PhD student and New England bee expert Nick Dorian will teach you about the natural history and conservation of wild bees that call Long Island home. Together, we’ll examine closely their varied lifestyles, their habitat needs, and their intricate relationships with flowering plants and other insects. You’ll come away with clear action items for creating habitat for native bees in your gardens and with a newfound appreciation for these charismatic pollinators.

Nick Dorian is an ecologist, an educator and a naturalist. He is a PhD student at Tufts University where he studies the population ecology of cellophane bees and runs the Tufts Pollinator Initiative, an urban pollinator conservation and community outreach group.

Renny Reynolds
Gardens in England & Their Influence on Hortulus | March 13, 2022

Our March speaker, Renny Reynolds will discuss garden design elements and explore their importance to all good gardens. Sharing slides of many English gardens, he will examine how these notable gardens have influenced him in creating his own garden, Hortulus Farm.

Renny Reynolds was born and raised in St. Louis, Missouri and received his Bachelor of Science degree from the University of Wisconsin, Madison, in Landscape Architecture in Urban and Regional Planning. After touring the world for three years as a travel guide for the firm Intrav, Renny moved to New York City where he started a small plant and garden shop in Greenwich Village. Bill Blass was an early client and Renny’s design for his terrace was featured in Architectural Digest. Many magazines including “W ”, House and Garden, Veranda, Elle Décor, House Beautiful, Fine Gardening, and Flower have featured his flower, event, and garden designs. Renny has worked for several presidential administrations for events both in and out of the White House. In 1992, he wrote the book entitled “The Art of The Party ”, which some designers still use as their bible. The business in New York City, Renny & Reed, became known across the country for the large and dramatic scale of the events.

Renny then turned his attention to designing many large-scale gardens and landscapes. With his partner Jack Staub, the noted garden author, Renny continues the work on his spectacular 18th century farm in Bucks County, Pennsylvania, which features twenty-four gardens. They have written a book about the gardens entitled “Chasing Eden”. Hortulus Farm, which includes a nursery on its one hundred acres, has received the accreditation of being an affiliate of The Garden Conservancy. Renny has served on the Board of Overseers of the Graduate School of Design at The University of Pennsylvania and the boards of The Royal Oak Foundation, The Heritage Conservancy, P.S.1-Museum of Modern Art, Bucks Beautiful, The Hetrick- Martin Institute and Fishermans Mark.

Andy Brand |After The Flowers Have Faded: Plants with Fabulous Foliage | Sunday, January 16, 2021

Flowers always get most of our attention when we are selecting plants to add to our landscapes. But most plants only flower for a short period of time out of the year. It is the foliage that we will be looking at the entire growing season. Join Andy as he explores a broad diversity of awesome plants whose leaves will shine in the garden.

For 27 years Andy Brand was employed at Broken Arrow Nursery in Hamden, CT, where he was the nursery manager. In March 2018, Andy joined the staff at the Coastal Maine Botanical Garden as Curator of Living Collections. His responsibilities include plant selection, introducing new plants to the Garden’s collection and maintaining plant records and labels. In November 2021, Andy was named Director of Horticulture there.

Andy is past President of the Connecticut Nursery and Landscape Association and is an avid naturalist. He is a cofounder and past President of the Connecticut Butterfly Association. He has put his interest in native plants to use as a volunteer for the New England Plant Conservation Program where he has helped monitor historical sites of endangered native plants. He has spoken to groups throughout the northeast on a range of topics including native plants, new and unusual ornamentals, butterfly gardening, butterflies and their life histories, and increasing biodiversity in landscapes. Andy, along with his wife Michelle, lives in Bristol, Maine. Andy also has a Facebook page, Seeing Nature: Observations from New England, dedicated to native flora and fauna.

William Cullina | What do You Mean I’m Not a Perennial!?! Native Shrubs and Small Trees for Perennial Companionship | October 17, 2021

Most folks are familiar with the concept of the mixed border – perennials, annuals, shrubs and evergreens blended together in a seamless composition year-round. It sounds good in theory but transplanting this concept into a real garden is more difficult than it seems. Not all woody plants mix well with perennials and annuals for several reasons, including differing soil and fertilization needs, incompatible growth habits, aggressive root systems, or fear of crowds. This said, there are a number of native shrubs and small trees that mix wonderfully with herbaceous perennials and annuals. Many can even be cut back every year or two just like their non-woody neighbors to control their size and promote flowering and vigorous growth. In this talk, Bill Cullina will profile his favorite fifty “natural mixers,” focusing native woody plants that bring, form, texture, color and wildlife to the perennial garden.

Roundtable | HAH Roundtable | It’s Winter: Let’s Start Gardening | Saturday, February 4, 2023

It’s February, and many of our gardens are at rest. But are our gardens, or are we gardeners, ever truly dormant? Or is February a wonderful time to grow our own winter vegetables (a smart idea after seeing the prices at the markets!), start new spring and summer plants from seeds, care for our tropical plants, force bulbs indoors for an early display, and plan for our whole new summer projects?

One of a gardener’s best friends in winter (almost ubiquitous in England but not as common for the home gardener on the East End), are GREENHOUSES. And we have just the right guest speaker to share his enthusiasm for utilizing greenhouses and other methods for winter growing.

Renato Stafford is an organic growing consultant with a culinary and business background and over 20 years of teaching, developing, and implementing programs for schools, restaurants, private residences, and estates. He specializes in the planning, design, and installations of year-round organic vegetable gardens and greenhouses; composting to nurture our plants; storing and preserving produce; seed saving and plant starts, and the organic winter garden. He also has tips for those of us who do not have greenhouses.

We also look forward to hearing from HAH members who are utilizing greenhouses, starting their own plants indoors using grow lights, bringing potted bulbs indoors to get a jump start on spring, direct sowing seeds outdoors, watching the garden come alive even during the winter, and seeing the daylight hours remain longer. It fills us with optimism and the renewed energy to get back to work on our gardening dreams.

So please join us in person on Saturday, February 4, 2023 at 10:30am and, if you have experiences of your own to share, we very much look forward to hearing your stories. Other gardening questions are also welcome, as are guests.

Roundtable | Managing the Challenges of Drought and Heat in Our Gardens | Saturday, October 1, 2022

What a gardening season it has been so far! We began with a cool and wet spring and early summer, only to be hit with an unusually dry and hot late July and August. So while this experience is fresh in our minds, and since we might face these conditions again, it seems like the perfect topic to begin our new season of Roundtable discussions. Here are some of the strategies we’ll cover:

  • Planting selections that thrive in and withstand these conditions while attracting pollinators (lots of great choices)
  • Watering and irrigation practices
  • Conserving moisture with soil coverings including    compost and mulch  
  • Strengthening your plants with organic soil amendments and conditioners
  • Creating and taking advantage of shady places in your garden

So please join the Zoom Roundtable, if you have experiences of your own to share, or any other gardening questions, we welcome your input.

Roundtable | Digging into Soil | Saturday, April 2, 2022

Please join us for our last Roundtable of the season. Our focus will be all about soil, which Merriam-Webster defines simply as “the upper layer of earth that may be dug or plowed and in which plants grow.” But we gardeners know that there is so much more to be said about the material on which our plants depend for all their nutrients and good health. In addition to soil, we will discuss making and using compost and even touch on the subject of gravel gardening.

Our principal speaker, Pat Nadosy, has become intrigued with the life under our feet in our gardens. She will discuss the critical role of soil microorganisms: their interaction with each other and with terrestrial plants, the networks they create, and their destruction by man-made soil ‘improvements’. She will also touch on cover crops and the effect on soil of different animals, and will refer to her favorite books on these topics.

Patricia (Pat) Harrigan Nadosy started her professional life as a Foreign Exchange trader at JP Morgan. After burn out as a currency options trader, she obtained a PhD in Botany, studying the antioxidant compounds of Rosemary. She is currently Vice Chair of the Board of the Carl Schurz Park Conservancy and a Zone Gardener, Chair of the Committee of Trustees of the New York State Board of TNC and Trustee emerita of Barnard College. She and her husband Peter are now living primarily in Southampton where Pat is Co-chair of the Grounds Committee of St Andrew’s Dune Church and helps out with the gardens at St. John’s Episcopal Church. Pat is also a former President of the Southampton Garden Club (one of the Tri’s with Marge Sullivan and Tish Bliss). Pat is also an HAH member.

From Lawn to Meadow: Enhancing Biodiversity in our Gardens | March 5, 2022

As we are all active in the fields of gardening and horticulture, we have heard from many experts that more is needed to be done to increase biodiversity, to reduce our use of synthetic fertilizers and pesticides, and to support our beneficial and endangered pollinators. And although many of us do not have acres to spare, we do have an opportunity to turn at least part of our properties into small meadows, borders with lots of pollinator-friendly plants, and to even rethink the very nature and composition of our lawns. So I’m pleased to announce that HAH member Erich Winkler has prepared a special presentation on this topic.

“Over the past few years, gardening has undergone major transformations from focusing primarily on beautiful plants to creating gardens that attract pollinators and include native plants – but what about our lawns? I will present various approaches to increasing biodiversity of lawns, thus creating a healthier environment, attracting pollinators, reducing maintenance, and improving soil health. While many municipalities and neighborhood associations still maintain strict ordinances on “appropriate” lawn maintenance, others are beginning to restrict pesticides, water use, and even provide incentives to convert lawns into meadows. Are we ready for the new challenge?”

Erich Winkler, who gardens in Southampton, is a long-time HAH member and garden and landscape design enthusiast. Now retired, Erich is spending an increasing amount of time gardening, and deepening his knowledge of plants and landscape design through lectures, garden visits, and courses at the NY Botanical Garden. Erich divides his time between the East Coast and Hawaii, and also serves as an Advisory Board member of the Consortium for Sustainable Urbanization.

In addition, it will also be a pleasure to once again welcome Brian Smith, Vice President of the Long Island Native Plant Initiative, who will mention his work with Rick Bogusch to create a new meadow area at Bridge Gardens.

So please join the Zoom Roundtable on March 5, and if you have experiences of your own to share, or any other gardening questions, we welcome your input.

Creating a Beautiful Shade Garden | February 5, 2022
Download plant list pdf here.

I used to think that for the many gardeners that live on woodland properties, designing with plants that thrive in shady conditions was an imperative, “needs must” situation. After all, don’t most plants thrive in sun and in a sunny garden? Wouldn’t we all choose to have a sunny garden? But it was not until I spoke with our next presenter, Lydia Wallis, that I learned that many gardeners also choose shady conditions, because working in the shade makes garden work possible and enjoyable during the heat of summer, or because the plants that thrive in some form of shade are irresistible standouts, or sometimes we start out with a sunny, open space and then we plant trees and shrubs that create shade as they mature.

Lydia Wallis, who gardens in Southampton, is a Master Gardener, a past president of HAH, a former president of the Southampton Garden Club (member of The Garden Club of America), a past president of the Wilton Garden Club (member of The Federated Garden Clubs of Connecticut), a former Inland Wetlands Commissioner in Wilton, and an Approved Horticulture Judge of the Garden Club of America. Lydia has also competed in many flower shows, winning several top awards.

I am so pleased that Lydia will guide us through her top selections of plants that thrive in shady conditions, including bulbs, rhizomes, and corms; perennials; groundcovers; and shrubs. She will also discuss such topics as why we garden in shade, types of shade, how to create shade if your garden does not have it, creating a true woodland garden with a natural style, incorporating colorful foliage plants, and how low light can show off plants to their best advantage.

Abby Jane Brody, a leading figure in the world of horticulture on the East End, will also be on hand to offer commentary and answer questions.

Winter Pruning
Last year, I visited Bridge Gardens and took several videos of Rick Bogusch demonstrating winter pruning techniques. Later, the staff at the Peconic Land Trust was able to combine these into one video. For the first time, I will “screen share” this video with HAH members at the February Roundtable. This is such an important garden task, and since our members always have questions about which plants should be pruned now, where the cuts should be made, etc., I really look forward to sharing this footage with you.

Propagating Your Own Plants from Seeds | January 8, 2022

Growing your own plants from seeds can be one of the most rewarding as well as economical ways to add annuals and perennials to your garden. And what better time to do this than during the winter days that you are otherwise only daydreaming about when you will next be able to work in your garden again?

I recall when, as a beginning gardener, I plunged in and started a variety of plants from seeds, and those became the backbone of my perennial herb garden, still thriving today. I still look at those herbs, and other perennials that I grew from seeds started indoors, with more pride than many of the other plants I purchased. In January and February each year I direct sow poppy and other annual plant seeds outdoors (amongst the most admired plants in my garden), and in early spring some annual and biennial herbs. And with advice and tips from our fellow gardeners, we can all start our gardening new year by giving this a try.

That is why I am pleased to announce that one of our own HAH members will help us do just that at our next Roundtable.

Dr. Jane Corrarino, who gardens in Setauket, NY, enjoyed a 40-year career in public health. After retiring, and with the pandemic altering her life, she decided to expand her gardening knowledge and skill set, which she has loved since childhood. Jane earned a Master Gardener certificate from Cornell, and is now a happy volunteer for them. Her volunteer action project for the Master Gardener program was to recreate a historically accurate colonial kitchen garden at the Ketcham Inn, a restored 1695 Inn/Museum in Center Moriches and on the National Register of Historic Places (Thomas Jefferson and James Madison stayed there in 1791). There are 3 gardens on site, including the kitchen garden, which contains herbs, vegetables and flowers all germinated from seed. In addition, they are restoring a boxwood garden and community garden on the site. And since Jane has said she welcomes anyone interested to visit the inn’s gardens, I hope this will be one of our in-person Garden Tour destinations later this year.

Plants to Make Your Late Summer Garden Dazzle |October 2, 2021

HAH member Pamela Harwood will present an extensive selection of August/September standouts, and we are very fortunate to welcome back Brian Smith, Vice President of the Long Island Native Plant Initiative, who will walk us through his own list of late-season-blooming plants that are native to Long Island. Both presenters will “screen share” photographs of these wonderful selections.

October is a good time to re-assess your garden while you can see all your plants in place (unlike spring when so much has not yet come up and you forget what is where!), garden centers are more likely to have these late-season plants in stock, and some may be on sale. The cooler temperatures will also enable plants to establish themselves before the hard winter frost and spring.

Question and answer followed.

Attracting Butterflies, Bees & Other Pollinators to Your Garden | April 3, 2021

As this was our last scheduled Roundtable before we’ll all be purchasing new plants and back outside spending time in our gardens, we thought the timing was perfect to discuss how important pollinators are to the success of our gardens and to the environment. And since not all plants, no matter how beautiful, attract pollinators, we want to focus on sharing information about the plants — be they trees, shrubs, perennials, and annuals — that do the job. Many of these selections of course will be plants that are native to Eastern Long Island. But others are native to other areas of North America and even other parts of the world. But they all share characteristics that attract and nurture pollinators in various ways and at various stages of their life cycles.

Sarah Alford will speak about attracting butterflies to your garden. Brian Smith, Vice President of the Long Island Native Plant Initiative, will focus on the native plants that host and nurture bees and other pollinators in our gardens. We will go beyond plant varieties and also suggest how various selections may be best placed in your garden for maximum enjoyment, and other garden elements that are important for our pollinator friends.

Q&A follows.

Explore the Versatility of Herbs with Joan DiMonda | April 17, 2021

With clear blue skies and warmer temperatures Spring is upon us. It brings with it a chorus of returning birds, the hum of buzzing bees and the rush of new emerging green shoots. Springtime reminds me of rebirth, renewal and reawakening.

In my herb garden all seems quiet, the noise level is low but the movement and activity underfoot is rapid and robust. CDC Guidelines have had us washing our hands many times this past year. Adding a fragrant herbal scrub to our routine will enhance this process…both a sugar scrub and a salt scrub will be discussed and prepared.

From sachets and potpourri to medicinal or culinary, herbs influence many areas of our life. Whether you are a one pot windowsill gardener, purchaser of fresh herbs at the local farmstand or worker in your own garden plot, you can expand your sense of the versatility of herbs.
