Classes

  HARLEQUIN’S GARDENS CLASSES AND EVENTS FOR 2019:

Our teachers have spent years honing their skills in Colorado and will help guide you to success. We are charging $15 (unless otherwise stated) for our classes to support our speakers and Harlequin’s educational direction. It is best to pre-register for these classes both in case they fill up, or too few people register and we have to cancel. Pre-payment assures your place in the class. You can register at the nursery, by mail, or by calling 303-939-9403. We are unable to take class registration by email at this time.
Most of our classes run from one and a half to two hours in length, and sometimes longer for hands-on classes or if there are a large number of questions.


Sat, Mar 2 at 1 PM – Mason Beekeeping with Tom Theobald
The importance of our native ‘solitary’ bee species to the pollination of our crops, flowers, and native plants is receiving increased attention. For over 30 years, Tom Theobald of Niwot Honey Farm has been propagating one of the most ‘useful’ species, Mason Bees (Blue Orchard Bees), and will teach how to attract and care for these gentle native pollinators. Mason Bees are not a replacement for honeybees, but they are excellent pollinators of the early fruits – cherries, apples, etc. They stay close to home, don’t sting, don’t require the year-round commitment of a colony of honeybees and provide a great way to introduce children to the world of pollinators. Harlequin’s Gardens will have filled straws (containing male and female adult bees in hibernation) for sale for $12 a straw. IMPORTANT: You must RESERVE your Mason Bee straws IN ADVANCE by calling Harlequin’s Gardens at 303-939-9403. Pre-payment of mason bee straws is required. Class cost: $15 This class will be repeated on Saturday, March 16th at 1pm.

Sat, Mar 9 at 10 AM – Introduction to Permaculture with Tara Rae Kent & Daniela Escudero
Permaculture is a design science that is informed by cycles and patterns in nature. This helps us create more resilient and regenerative systems, whether those systems are gardens, farms, businesses, or events. We will explore the ethics that guide a permaculture design and the principles that help a design take form, as well as real life examples and projects that are a part of our lives. The class will include: 1) an introduction and exploration of the Permaculture Ethics and Principles, 2) real life, active and diverse examples of permaculture designs, and 3) a tour of Harlequin’s Garden’s Permaculture Design. Free admission!

Sat, Mar 9 at 1 PM – Cover Crops for Gardeners: Why, How & Which with Clark Harshbarger
In the current soil revolution, we are learning how to nurture and care for our soils and the soil life that is the true source of soil fertility. Cover crops are becoming recognized as one of the keys to soil fertility and soil health. When our annual crops die in the fall, if we do not replace those crops with living plants, then the microbes that depend on the nutrients “leaked” into the soil from plant roots, will die or decrease.

Besides that, cover crops are a method to use photosynthesis to grow organic matter and nutrients including nitrogen to add to the soil, so we have to buy fewer amendments. In addition, many cover crops support beneficial insects which help control pest insects, and they reduce erosion.

But which cover crops do well in Colorado and when do we plant them and when should we cut them, and how do we prevent them from becoming weeds or competitors? And how best to combine them?

Harlequin’s Gardens has been looking for someone to teach us these things, who really knows how to do it in our local conditions. And this year we found the right person. So this is a great opportunity that will not be available next year, because Clark Harshbarger will be moving to eastern US.

We have reserved a bigger space than our classroom, but people will have to register ahead of time to make sure they get a seat. Register by phone at 303-939-9403 This will be a 2 hour class and we will be charging only $20. This class will be taught by Clark Harshbarger.

For the last two decades, Clark was employed with the USDA-NRCS as a soil scientist and recently as director of Regenerative Farming at MAD Agriculture. It will be held on Saturday, March 9th from 1-3 pm at the Boulder Circus Center, next door to Harlequin’s Gardens, south in the big metal building in the Trixie Room.

Clark’s description for his class: “Cover crops are essential to any regenerative garden or farm. They have been shown to reduce soil erosion, conserve soil moisture, enhance and protect water quality, and build disease and insect resistance by providing diversity to crop rotations. In this hands-on class, learn how cover crops can improve soil fertility and reduce insect and weed problems. We will discuss when and where to plant them and how to determine what species to select.” Class cost: $20
