Rose Pruning Basics (March 14, 9:30am-12:30pm
Lucy Dinsmore
Horticulturist, Morris Arboretum

Early spring is the time to get your roses ready for a season full of blooms. This class is held outdoors in the Rose Garden, and will provide an overview of spring rose care including pruning, planting, transplanting, fertilizing, and disease prevention. A pruning demonstration will follow, and then you'll have the opportunity to test your skills on our roses. Consulting rosarians from the Philadelphia Rose Society will also be available for one-on-one guidance and to answer your questions. Be sure to dress warmly, bring your hand pruners and gardening gloves, and be prepared to get your knees dirty. Due to the individual attention, class size is limited. Meet at the Vistors Center.

Weeds at Our Feet (March 21, 1-2pm)
Rachel Mackow
Co-owner, Wild Ridge Plants

The edges of our paths, gardens, and lawns are home to resilient plants. Dandelion, plantain, violets, and others are often rogued out by hand or with pesticides, though they have traditional uses as food and medicinal remedies. Many of our weeds also serve an
ecological role in the garden - providing nectar, pollen, and habitat for wildlife including pollinators, birds, spiders, and salamanders. This hour-long presentation by Rachel Mackow will weave together the ecology of common native and non-native plants with their modern and historical uses. Learn which common weeds host butterflies, which are high in healthy fats, and where to find the plant called "nature's bandage".

Gardening for Planet Earth: 10 Ways That You Can Make a Difference (April 7, 7-9pm)
Marc Radell
Penn State Master Gardener

Climate change. Vanishing species. Polluted water. The list of environmental problems today seems endless. But there is hope, gardeners, and some of it rests with you! Over the last few decades, suburban development has replaced agriculture and open space as the largest class of land use in the Delaware Valley. This means that the welfare of the environment is largely in the hands of you, the homeowner. This class will address eco-friendly gardening from two perspectives: 1) what the most serious environmental issues are today and how we gardeners can help mitigate the damage; and 2) what common gardening practices cause the most harm to the environment and how we can change them. We shall cover in detail 10 gardening practices that you can implement to make a difference in protecting the environment and many other "bonus" tips based on the instructor's experience as an environmental professional and Master Gardener.

Hypertufa Trough Workshop - Session I (May 30, 10am-12pm) (Class is Full)
Louise Clarke
Horticulturist, Morris Arboretum
Anna Bower

Natural Lands Intern, Morris Arboretum
Join Arboretum staff for a delightfully messy, hands-on hypertufa trough-making workshop. Hypertufa is a lightweight, porous concrete mixture made from Portland cement, peat, and perlite that mimics tufa rock. Your small, weatherproof container will welcome plants that like well-drained conditions such as sedums, hens and chicks, and rock garden plants. Ideal for those with limited space, troughs can be planted as miniature gardens or to display choice specimens. Your instructors will provide individual attention and step-by-step instructions from mixing to molding to aftercare. Please bring a small cardboard box no larger than 8" x 10" x 5" deep to use as the
form. Also bring a plastic grocery bag, a pair of sturdy kitchen-type rubber gloves (mandatory) for working with the cement mixture, and a board or piece of plywood large enough to transport your trough home for final curing. Wear clothing that you won't mind getting dirty. We will meet at the Horticulture Center at Bloomfield Farm. Look for the paved road across Northwestern Avenue from the public garden entrance. Park in the lot and follow the signs to the Horticulture Center.

Hydrangea Heaven: Class and Garden Tour (June 27, 10am-1pm)
Nina Schneider
Garden Designer

For the amateur or experienced gardener with a small or large garden, no single genus provides as much variety in form and color for summer bloom as hydrangea. While offering the benefits of low maintenance, this vast group of shrubs can provide winter interest in the peeling bark of the oak leaf hydrangea, spring color in the earliest bloomer, H. bretschneiderii (no relation) and a rainbow of floral display throughout the entire summer and into September with H. involucrata. We will review all of them, large and small, sun and shade lovers, native and Asian; how to propagate them and how to prune for vigor and bloom. Meet at the Arboretum. Our morning will start with an overview of the whole genus, followed by a tour of the Arboretum's collection and concluding with a tour of the instructor's garden in nearby Chestnut Hill to see many more with an emphasis on right plant for the right place and where to get them.
