VICKSBURG, Miss. -- Mississippians from a wide variety of backgrounds spent a day thinking of new ways to use landscapes and gardens to bring more profit and better value to agricultural enterprises and historic homes.
Know Your Roots: Build Your Business brought 29 participants together for the daylong workshop June 13 at the Southern Cultural Heritage Center. Sandy Havard, Warren County agent with the Mississippi State University Extension Service, coordinated the event.
HATTIESBURG, Miss. -- Lida McDowell taught science and math for 30 years at the high school and university levels, and she keeps finding ways to educate while enjoying an interest she had no time to pursue until retirement.
The raised-bed vegetable gardens she and church friend Karen Walker maintain year-round serve as a classroom for a young audience at Thames Elementary School in Hattiesburg.
“What we’re trying to do is get the kids to enjoy nature, be outside and appreciate where their food comes from,” McDowell said.
TUPELO, Miss. -- For more than a quarter century, Mississippians with a love for horticulture have been helping to educate and serve their communities through a nationwide Extension Service program.
STARKVILLE, Miss. -- Long before Charlie Weatherly earned the state’s 2015 Master Gardener of the Year honor, his family roots were dug deep into the Mississippi soil.
Although he retired from Mississippi State University in 1997, Weatherly has not strayed far from the land-grant institution’s campus or mission. How could he? As a child, he frequently came to campus with his father, Ernest, who was a county agent for what is now the MSU Extension Service.
PURVIS – The Pine Belt Master Gardeners reached a milestone June 19.
The group constructed its 100th salad table, which is designated for donation to the University of Southern Mississippi’s Office of Sustainability. It is one of many the group has donated throughout the last year.
When the Pine Belt Master Gardeners built two raised beds for demonstration at the Mississippi State University Lamar County Extension office in 2013, they did not expect the educational project to become so popular.
