Classes and workshops

Juniper Level Botanic Garden has been offering horticulture classes since the late 1980s as part of our mission as an educational, scientific, and research-based botanic garden. We aim to raise awareness of the horticultural and gardening misinformation offered by well-meaning garden speakers and writers, from plant adaptability to soils and fertilizers.

Our garden is your classroom

Sharing the knowledge

A key part of our mission is education. We’ve probably killed more different plants than anyone currently alive, but with each failed attempt we learned something new. Between that and our successes, we have a lot of knowledge and experience to share, and are passionate to do so. Sadly, much of the gardening information on-line is simply incorrect, and continues to get repeated ad nauseum without ever being vetted for accuracy. Think of us as the horticultural Snopes for plant myths. We truly love to share what we’ve learned. Whether it’s in a classroom setting or in the garden, you‘ll go home with a new understanding and appreciation of the natural world.

Renewal pruning class
Tue, Feb 13 | 2 – 4PM | $45

Cutting Up the Garden

Renewal pruning of shrubs is an essential skill for all gardeners growing flowering shrubs (plus blueberry and brambles). Though it is not applicable to all flowering shrubs, it does apply to the majority of deciduous flowering shrubs. Renewal pruning maximizes the productivity of a plant, which means more flowers and fruit. This class will start with classroom instruction followed by demonstration in the garden.

Spring ephemerals class
Tue, Mar 12 | 2 – 4PM | $45

Spring Ephemeral Garden Walk

Many of our native plants flower during the spring season and go dormant before the onset of summer. Join our garden staff to explore many of our fabulous spring ephemerals as we all wake back up from winter’s cold. Juniper Level Botanic Garden has one of the largest and most complete collections of spring-flowering natives so there’s no better location for learning them and the conditions that will lead to success with them in your home garden.

Wet soils class
Sat, June 1 | 10AM – 12PM | $45

Don’t Fight the Site – Wet Soils

Wet Soils should be celebrated and not considered a liability. There is no end of plants that thrive in wet soil and some which must have wet soil. This class will focus on plants for wet soils and how to deal with wet soils. Wet areas often become an asset during dry spells when the rest of a garden is too dry. Many wet-site tolerant plants are also suited to rain gardens. You will go away with a new appreciation of the wet sites in your garden.

Propagation workshop

The Basics of Propagation Workshop

Our interactive propagation workshop has become one of our guaranteed sellout classes each year. The day-long hands-on workshop will cover an amazing array of propagation techniques including seed, cuttings, divisions, plant breeding, and darn near everything but grafting. The focus of the workshop is perennials, but the techniques can be adapted to most plants. By the time you are finished, you’ll leave with lots of goodies and feel ready to start your own nursery. The class is held in our non-air conditioned shipping shed, so it may be quite hot during the class…dress accordingly.
