Chris Morgan is fascinated by the patterns and textures in nature, the shapes of trees, and the movements of birds. He captures these beautifully in his photographs, which were on display at the Arnold Arboretum in the winter of 2019.

In this program, Chris will discuss his photographic interests and methods in the classroom and then move outdoors to demonstrate his techniques. Class participants will be able to learn alongside Chris, evaluating views, debating camera angles, and considering focal points in order to shoot better images. Participants should bring their...

Soil is the basis of survival. Without soil, humans and most other living beings could not exist. Conor Guidarelli, who has dug deep into the soils of the Arnold Arboretum will present an overview of soil, from its formation and components to its properties. He will discuss ways to analyze soil quality and health to determine whether or not amendments are needed based on the soil outcome or use desired.

Participants are encouraged to bring a pint glass jar with about a cup of soil in it to class.

Cost: $20 for members; $30 for nonmembers.

Ensuring the long-term health of your landscape starts with healthy plants from the nursery, proper site selection and preparation, and sound planting and establishment. Andrew Gapinski will discuss professional standards and techniques, along with common issues and solutions for both balled-and-burlapped and containerized specimens. He will focus on landscape trees, shrubs, and perennials—ornamental annuals and vegetables will not be covered in this offering. Class will start indoors and then move outdoors to the Dana Greenhouse Nursery.

A wanderer and writer with a doctorate in religion, Gavin Van Horn inhabits a big city. And that city (Chicago) has offered him something to compliment and complicate the solitude of the woods or a remote mountainside: a window onto the attractiveness of cities to animals. What was once in his mind essentially a nature-free zone turns out to be a bustling environment where millions of wild things roam. He came to realize that our own paths are crisscrossed by the tracks and flyways of black-crowned night herons, Cooper’s hawks, brown bats, coyotes, opossums, white-tailed deer, and many...

Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...

Back by popular demand with more content! Terry Huang’s bawdy botanical review delves into the sex lives of plants, dramatically explaining the challenges of courtship and consummation for those rooted in place. Alluring suitors with a pungent rotten odor, promising nectar for the exchange of goods, or going at it alone, plants have evolved interesting strategies to ensure their continued existence. From mutualistic partnerships to deceit-filled...
