Weekly Article Update – 3/27

OSU Extension Greene County

Weekly Article Update for the Week of March 27, 2020

Agriculture and Natural Resources

During these unprecedented times for many of us, I thought it was important to start off this column by taking our minds off things even if it was for just a moment. While our physical office is closed, we are committed to continuing to conduct our work as fully as possible. We are teleworking from our homes and are ready to serve you. In recent years, OSU Extension has invested in the technology needed to facilitate effective teleworking for our organization; and we will utilize our resources during this challenging situation to remain engaged with you. Clients, stakeholders, and other community members should continue to connect with any OSU Extension staff member via phone or email as usual. As a matter of fact, if you call the Extension office, the call goes straight to our computers or cell phone and we can answer your call. If you need to contact me directly, please call me at 937-971-2544 or e-mail me at

I know there are many events and activities going on this time of year and many are in the process of being moved to a virtual setting. The best way to stay informed is by checking out our website at or by subscribing to our blog. Just type in this link ( and scroll to the bottom of the page to type in your email address then select subscribe! We post updates for 4-H, Agriculture and Natural Resources, Family and Consumer Sciences, Master Gardener Volunteers, educational events, and other opportunities available for all ages from youth to adult.

The heavy rain last week only compounded problems for our farmers. Nonetheless those that want to work in the yard and garden beds. With more rain forecasted, I hope this will soon pass and things start drying out. Animal and crop production are considered “life sustaining” by the government and needs to keep pushing forward. Hopefully the changing of the season and warmer temperatures will give us a good spring and allow the crops to get in the ground in a timely manner and allow the pastures and hay fields grow for our livestock.

Speaking of springtime ventures, now is a good time to test your soil. Our office can help in sending your soil off to the lab and then giving recommendations on successful growing. Even though we aren’t in the office, you can visit our website, pay online and get your soil sample to the lab. More information on this is at

If you have a chance, take a few minutes to go outside and enjoy nature (but keep you distance from others). It is refreshing to see blooms start to appear as they did over this past week. Speaking of our current changes in life, it seems fitting to end up today’s column, with this quote from Anna Quindlen: “Don’t ever confuse the two, your life and your work. The second is only part of the first.” Have a great week and be safe.

4-H Youth Development

There are many 4-H books geared towards youth to learn basic home production.  Ohio 4-H has about 15 different 4-H publications geared towards natural resources and gardening.  For example, Ohio 4-H has a publication called “Canning and Freezing.”  This would be a wonderful publication to work through with children to learn the importance and the correct steps in canning and freezing foods.  In addition, spring is a perfect time to plan for a summer garden.  Engage youth in helping to design the garden and deciding what plants to grow for this coming summer.  To take a sneak peek at 4-H publications, please visit  If you want like to order any publications, please contact our office or email me at

There are opportunities for our Cloverbuds to be actively engaged in home production as well.  There are wonderful hands-on activities for youth ages 5-8 to participate in gardening activities.  Visit this blog for more ideas.  One of my favorite activities while planning the garden, is to have the youth eat a whole plant.  For example, carrots can be the roots of a plant.  Celery can be the stem.  Spinach leaves can be the leaves of the plant.  Broccoli can be the flower of the plant.

Enjoy this time home and take advantage of it as a learning experience.  Have fun.  Get dirty.  Make memories.

Helleborus orientalis: The Beautiful Harbingers of Spring by Kim Hupman

After what seems to be a long, grey and gloomy winter, the sight of my Helleborus orientalis (Lenten rose) beginning to bloom assures me that early spring is upon us.

Helleborus orientalis is a clump forming, evergreen shade perennial that typically grows 1 – 1 ½’ and blooms late winter to early spring. It has palmate, serrate, leathery, 8-16″ wide, glossy, dark green leaves (7-9 leaflets) are evergreen in mild winters but deciduous in extremely cold winters. Helleborus need to be sheltered from winter winds as the leaves may become scorched and tattered. The plant bears nodding or outward-facing, saucer-shaped, flowers, of white, pink, green, primrose, mauve or smoky purple in color. The flowers will remain for 8 – 10 weeks.

Helleborus is a low maintenance perennial who’s few needs include removal the scorched or winter damaged foliage and applying a slow release granular fertilizer around the time it blooms. The task does not take a great deal of time. Be sure to apply the fertilizer at the drip line of the plant (where rain drops from the end of the leaf and then falls to the soil) and not on the crown of the plant. Helleborus uses a lot of energy when in bloom as it is also producing new growth at the same time. Besides being a low maintenance plant, Helleborus are deer resistant They do best in part to full shade and well-drained soil with protection from the winter wind. They are an excellent border plant or make a great back drop for lower growing shade plants such as Hakonechloa macra “Aureola” (golden Japanese forest grass), Veronica umbrosa “Georgia Blue” (creeping veronica), and miniature hosta.

Helleborus orientalis is a wonderful low maintenance, deer resistant perennial and a beautiful harbinger of spring. Consider adding this plant to your shade garden.

OSU Extension Announces Agriculture and Natural Resources Madness: A Tournament of Education

Columbus, OHIO – Did your usual conference get canceled? Looking to fill the void of the big basketball tournament? Ohio State University Extension is here to help with a new virtual education program for farmers.

Agriculture and Natural Resources Madness: A Tournament of Education will include 64 educational events broken into daily brackets. Each day, a virtual educational session will be held at 9 a.m., noon, and 3 p.m. The education tournament is free of charge and will likely continue until mid-May.

“This effort is a direct response to providing a variety of useful and timely sessions for farmers across the state during Governor DeWine’s stay-at-home order,” said Jacqueline Wilkins, interim director of OSU Extension. “While our ‘tournament’ is being loosely tied to March Madness, it’s not a competition, and people can join in at any time for as many or as few sessions as they desire.”

The tournament opens on Wednesday, March 25 with the eFields 2019 Results webinar. Learn how the eFields program utilized modern technologies to help Ohio farmers learn new practices and techniques to improve farm efficiency and profitability. Tip-off is at 9 a.m.; and registration is required at

Also in this bracket is a March 25 noon webinar from Sam Custer, interim assistant director of OSU Extension’s Agriculture and Natural Resources program, to discuss how educators are working remotely to continue serving Ohioans during these uncharted waters of the coronavirus disease 2019 (COVID-19) outbreak.

Tournament “brackets” will change daily. Topics will cover a variety of subjects and be presented in a variety of virtual platforms. When possible, question-and-answer opportunities will be included.

To find complete details on the tournament’s educational opportunities and other event and webinar links, visit

The Agriculture and Natural Resources online tournament is just one example of how OSU Extension is employing its resources during this challenging time to remain engaged with Ohioans. “The intent is to reach the agricultural community in a time of high stress,” Custer said. “OSU Extension has also updated its Ag Crisis website to include a toolbox of resources related to COVID-19. Those can be reached at”

OSU Extension has implemented a teleworking plan effective immediately, and all OSU Extension offices statewide are closed until further notice. The plan mirrors The Ohio State University’s decision last week to require all employees who can do so to work from home and to maintain only critical services on university property across all campuses.

Clients, stakeholders, and other community members can continue to connect with any OSU Extension staff member via phone or email as usual. To contact your local Extension office, visit for office phone numbers and a direct link to each office’s website and staff directory. If you reach voice mail, please leave a message with your name and contact information, and you will be contacted as soon as possible.

OSU Extension is the outreach arm of Ohio State’s College of Food, Agricultural, and Environmental Sciences (CFAES), and works to share knowledge with every county in Ohio. Its four major program areas are family and consumer sciences, 4-H youth development, community development, and agriculture and natural resources.

OSU Extension offices throughout Ohio will implement teleworking options for staff amid current coronavirus disease 2019 (COVID-19) outbreak concerns

March 18, 2020


LOCAL CONTACT: OSU Extension Greene County

OSU Extension offices throughout Ohio will implement teleworking options for staff amid current coronavirus disease 2019 (COVID-19) outbreak concerns

Columbus, OHIO – Governor DeWine recently issued a state of emergency for the state of Ohio, and along with the Ohio Department of Health, has implemented a variety of strategies to reduce the spread of coronavirus disease 2019 (COVID-19). To do our part in reducing risk to Ohio State University Extension employees or clientele, we have implemented a teleworking plan effective immediately, and all OSU Extension offices will be closed to the public until further notice.

This mirrors The Ohio State University’s decision earlier this week to close university buildings and facilities on all of its campuses to “critical services” only (such as law enforcement and public safety; hospitals and health services; facility utilities; and a few others).

While our physical offices will be closed, we are committed to continuing to conduct our work as fully as possible. Our employees are prepared to telework and are ready to serve their local clients and communities. In recent years, OSU Extension has invested in the technology needed to facilitate effective teleworking for our organization; and we will utilize our resources during this challenging situation to remain engaged with Ohioans. Clients, stakeholders, and other community members should continue to connect with any OSU Extension staff member via phone or email as usual.

Reopening of any county office facilities will depend on decisions from the governor and the state of Ohio, as well as The Ohio State University. The exact date when normal operations are expected resume in county Extension offices is unknown at this time. Until then, OSU Extension office staff will be working remotely and will remain accessible and available via email and phone. The health and well-being of our stakeholders, event participants, and employees is of utmost importance.

Each OSU Extension office has developed a business continuity plan that outlines how Extension staff will operate during situations such as the coronavirus outbreak. All staff will continue to work and serve local clientele through normal office hours (as previously determined by each county), and they will remain accountable for program management needs.

Please note that most Extension-planned activities from now through April 20 are now postponed, scheduled to be held virtually, or cancelled. If you have not already been contacted about an event or activity in which you were scheduled to participate and you have a question, please check with your local contact for that event.

Thank you for your cooperation and collaboration related to the coronavirus disease (COVID-19). The Ohio State University remains committed to the health and well-being of our community; and OSU Extension remains committed to serving our communities in each county as this situation evolves. These are unprecedented times, and we sincerely appreciate your flexibility and support.

If you have questions, please contact your local OSU Extension office.
