Saturday, June 29 from 10am - 12n - Class is FREE! Phenology - the study of the timing of biological phenomena and their relationship to the weather and climate - is a Biological Calendar for when to start seeds, when to plant, what to plant to attract pollinators, when to control pests and how to design gardens for seasonal long interest. Records are kept at over 30 Replicate Ohio gardens with meticulously recorded temperatures, bloom times and pollinator activity for fifty-five plants. Learn how this ancient science has been updated using temperature dependent Growing Degree Days (GDD), the Internet, OSU Scientists and Master Gardener Citizen Scientists. Take instructional guided tours of the Master Gardener maintained Geauga County Phenology Garden and the Certified Monarch Waystation at the Patterson Center in Burton. Learn which flowers butterflies prefer, what host plants caterpillars require and what herbs, annuals and native plants to add to your garden to attract butterflies.
