Trees in the City—Planting, Maintenance, and Enhancement

1. Planting Trees in Urban Areas

Instructors: Wojciech Gieburowski, Anna Malik

Wojciech Gieburowski, M.Sc. (Eng.) – a long-time court-appointed expert in tree conservation, an appraiser for the International Society for Tree Culture and Conservation, a specialist in dendrology and arboriculture, and a supervisory inspector for Federacja Stowarzyszeń Naukowo-Technicznych (NOT)—SITO and MTUiOD; president of Taxus Arbor.

Anna Malik, Engineer – A graduate of the Warsaw University of Life Sciences (SGGW). Since 2013, she has been a Green Space Supervision Inspector, a certification she obtained from SITO-NOT in Warsaw; she joined the association in 2025. For the past 25 years, together with her husband Krzysztof and her brother Marcin, she has been running a nursery in the municipality of Mszczonów, in the village of Badów Górny, covering an area of approximately 40 hectares. They specialize in growing trees ranging from 2 to 12 meters in height, both in open ground and in containers.

More than 30 years ago, father, Józef Smolorz, purchased his first tree-transplanting machine with a 200-cm bucket diameter. Over time, thanks to hard work, the fleet grew to 15 transplanters used for the farm’s needs and to provide services to outside clients.

Proper tree planting is crucial for ensuring that trees take root and remain healthy in challenging urban environments. The training will cover the principles of selecting nursery stock, preparing the planting site, planting and anchoring trees, and caring for them after planting. Participants will also learn the most important principles of tree transplanting, the factors that determine the success of this process, and the most common mistakes that lead to the weakening or death of trees.

2. Pruning and caring for young street trees

Instructor: Aleksandra Kruszewska, M.Sc. (Eng.) – a graduate of the Horticulture program at ZUT in Szczecin, a long-time tree diagnostician who holds, among other qualifications, a certificate as a veteran tree specialist, an OSTO stand management inspector, a practitioner, and an active tree climber, arborist at Arborist Sp. z o.o.

Proper care of young trees helps minimize future problems related to safety, maintenance costs, and conflicts with infrastructure.
The training will cover the principles of shaping the crowns of young trees, performing formative pruning, and correcting crown structure defects. Participants will also learn about best practices for tree care that can help reduce future maintenance costs and increase the trees’ chances of thriving in urban environments for many years to come.

3. Inventory of Tall Vegetation

Instructor: Arkadiusz Mroziński, M.Sc. (Eng.) – an expert in dendrology, tree conservation, and tree cultivation; a graduate of the Faculty of Forestry at the University of Agriculture in Kraków; has been professionally involved in tree condition assessment, conservation, and care for over 25 years; conducts inspections at historic sites; performs tree inventories and dendrological assessments, including specialized diagnostic tests such as sonic tomography and load-bearing tests.

A thorough tree inventory is essential for informed green space management and investment planning. This training session will focus on the principles of conducting tall tree inventories, the scope of data collected, and its practical application in design, administrative, and investment processes. The session will cover methods for assessing tree condition and the formal requirements for dendrological reports, as well as modern tools that support fieldwork and the analysis of inventory results.

4. Enhancement of Urban Trees

Instructor: Edyta Rosłon-Szeryńska, Ph.D., Eng. – Assistant Professor in the Department of Landscape Architecture at the Warsaw University of Life Sciences (SGGW), a specialist in trees in urban environments, the assessment of their condition, value, and safety, as well as green space management. Author of the Visual Identification of Trees Threatening Safety (WID) method, used in the hTreeEval system, as well as numerous publications and studies on landscape architecture, urban greenery, and the protection of valuable trees. A landscape designer with experience in project execution and supervision, an expert, an ad hoc court-appointed expert, and a developer of green space standards and best practices for tree management.

Urban trees serve important ecological, social, and economic functions, which is why the ability to assess their value is becoming increasingly important. This training will focus on methods for valuing trees, taking into account both their biological and landscape characteristics as well as the ecosystem benefits they provide to city residents. The practical applications of tree valuation in investment processes, green space management, and the protection of valuable trees will be discussed.

To mark the release of the book ‘Piet Oudolf: The Garden Designer’, Katarzyna Bellingham will discuss one of the most important contemporary garden designers—the Dutch artist who changed the way we think about plants, seasonality, and the beauty of gardens.

Piet Oudolf is a master of naturalistic plantings. His gardens are not static compositions, but living landscapes that change throughout the year. Perennials, grasses, colors, and textures come together to create multi-layered, painterly arrangements—beautiful not only in full bloom, but also in fall and winter, as the flowers fade and nature transitions.
During the event, Katarzyna Bellingham will explore Oudolf’s design philosophy, discuss his most significant projects, and illustrate what makes his perspective on gardens so unique. She will also present the book *Piet Oudolf. The Garden Designer—a richly illustrated monograph that offers a glimpse into the designer’s studio: his sketches, drawings, planting plans, and the process of creating gardens.
This event is for everyone who loves gardens, is interested in design, nature, landscape, and art—as well as for those who want to better understand why Piet Oudolf’s gardens have become one of the most important inspirations in contemporary gardening.

Piet Oudolf is an influential Dutch garden and landscape designer who spearheaded the New Perennial Wave and is the author of numerous books on gardens and landscape design. He has created many residential and commercial gardens, both public and private, and his work can be admired throughout the Netherlands, the United Kingdom, Ireland, Germany, Sweden, and the United States. Among them are such famous sites as the High Line in New York, Lurie Garden in Chicago’s Millennium Park, the Hauser & Wirth gardens in Somerset and on Menorca, the Sculpture Garden at the Singer Museum in the Netherlands, and garden installations created for the Venice Biennale and for the Serpentine Gallery at its specially built pavilion. Piet won a gold medal and the title of “best of the best” at the Chelsea Flower Show (2000), received the Veitch Memorial Gold Medal from the Royal Horticultural Society (RHS) (2002), and the Award for Outstanding Achievement from the Society of Professional Landscape Architects (2010). In 2013, he was honored with the highest Dutch cultural award, the Prince Bernhard Cultural Award (Prins Bernhard Cultuurfonds).

Katarzyna Bellingham — gardener, garden designer, and advocate for natural gardening methods. Author of the books *The Bellingham Garden*. How to Garden in Harmony with Nature, Secrets of the English Garden, and A Good Year in the Garden, in which she shares her knowledge of organic gardening, working in harmony with nature’s rhythms, and creating a garden that is friendly to people, plants, and animals. She runs the Bellingham Garden in Kashubia—a place where gardening practice is combined with education, nature observation, and the daily care of the living landscape.
