Welcome to our week-by-week (during the growing season) account of the findings in the Phenology Garden at Lake Park. This garden is tended and monitored by Coshocton County OSU Extension Master Gardener Volunteers as part of their ongoing education and training, as well as, gathering and entering data for both the OSU Bee Lab and the Ohio Phenology Calendar.

The study of recurring, seasonal biological events and their relation to weather. Examples of such phenological events include bird migration, autumn leaf color, insect emergence, and budburst.

How Do We Use Phenology?

Phenology is one of the oldest sciences. Hunter-gather societies use the knowledge of seasonal events to plan when fruits and berries ripen and to predict when animals migrate for hunting.

We can use phenology to study climate change by documenting the start of spring and fall over the decades. We also use plant phenology to help predict pest emergence because both plant and insect development is temperature-dependent.  Phenology can also helps us to design gardens with season-long interest.

The Pollinator Phenology Research in Coshocton County

• OSU Master Gardener Volunteers visit the gardens weekly to record data on first and last bloom of each plant. 
• In 2014, the Phenology Garden Network was expanded to include data on pollinators. In addition to the data on blooming, Master Gardeners now collect data on which pollinators are visiting the garden through the season.
• 11 species of native plants were added to the phenology gardens for this new objective. Coshocton’s garden started with these 11 and continues to grow!
• The goal is to learn more about pollinator activity and flower preference across the entire blooming season.
• This information may help to recommend preferred plants for pollinator gardens that span the blooming season.
