Teaching about trees, their amazing woody bodies and lives, and how to care for them, is something I have been doing my whole adult life. Questions come from nature, such as what tree is that, or what is wrong with that tree?
Answers come from our established world of knowledge, books, perhaps, or the internet. You take your tree problem to a book, learn something, then take it back to the tree. Complete this natural cycle enough times and you gain wisdom, wisdom to make the best choice of action about how to help the tree, action that harms the tree the least.
When you have gained that wisdom, generally the answers are straightforward. For example, this suffering tree with little vigor, a wilted look accompanied by minimal growth the last few years, just needs more water, and little else. But learning to diagnose that and looking for the signs written in the tree and its growing environment takes experience. It's the thinking about the whole tree and the space where it lives that lets us know how to help.
Tree classes can be about many subjects or focus on just one or two. Whether it is shrub pruning , soils, insects and diseases, tree and shrub identification, pruning theory, basic botany, compartmentalization of wounds, or a mix of many subjects, your class can be whatever you want it to be.
Whether you are one person, a group or a classroom, we can make a class work, either in your garden or in one of many outdoor spaces.
If hands-on pruning lessons are what you need, this has to be performed on your own private property.
I like to keep these classes open and flexible rather than rigid. Ask me about how you would like to handle this, and I am sure we can work it out.
