Class Time: 1 pm 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 honey bees, 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 honey bees and provide a great way to introduce children to the world of pollinators. Harlequin’s will have filled straws (containing male and female adult bees in hibernation) for sale for $12. IMPORTANT: You must RESERVE and PRE-PAY for your Mason Bee straws IN ADVANCE by calling Harlequin’s Gardens at 303-939-9403. This class also offered 3/15, 3/21 and 3/22
