It is a rapid way to launch a website for those retailers with a limited online store presence.

More than ever, national and state industry associations are providing the most up-to-date information on rules and regulations around coronavirus closures, resources for businesses, and information from government officials. If you aren’t already, strongly consider becoming a member to support them and to receive timely information. AmericanHort, the national horticulture industry group, has a Coronavirus Resource Center that includes:

• Federal relief efforts
• Small business assistance
• Workforce
• Business best practices
• Communications and management tips
• Garden retail resources
• Webinars

Retailers will also want to check out federal assistance programs such as the United States Small Business Association (SBA) Paycheck Protection Program (PPP) program. This program is a part of a large government stimulus package for financial relief during the coronavirus pandemic. More stimulus packages may be passed depending on the duration and severity of the closures from the pandemic. Business owners should monitor this and other programs. During this time of extreme stress, MSU Extension's Farm Stress Program is now connecting farmers to licensed therapists via teletherapy. Stay tuned to MSU Extension as guidance is released for farmers working to keep employees safe.
