Children receive special attention at the Institute. Florence Rodale, Anthony's wife, heads up the farm's creative department. In a small barn, she and two educators create learning materials and Web-site pages for children, featuring the adventures of Professor Redworm, the Institute's mascot. They've designed educational displays on regenerative farming for a traveling exhibit hosted at Capital Children's Museum in Washington, DC, Epcot center in Florida, and at the Institute itself. Last year, the Institute gave awards to Pennsylvania schools growing organic gardens.
"Anthony and I really care about kids. They will determine the future of regenerative farming," she explains.
Adult learning is equally important. Twice yearly, the farm hosts "Learning Capsules," daylong seminars and lectures on organic techniques. The demonstration garden, which has always drawn the most attention from visitors, will be renovated this year to make it friendlier for self-guided tours touring.
"We're looking at all our communications because we want to do a better job of explaining what goes on at the farm," Florence Rodale says. "People come here for information."
They also come because the Institute holds a special place in their hearts. On any given day, cars with out-of-state plates sit in the parking lot, driven here by backyard gardeners making their pilgrimage to the farm. To many of them, The Rodale Institute is hallowed ground. They quiz the garden staff, buy armloads of how-to texts in the bookstore, or sit meditatively under one of the big shade trees, admiring the farm's remarkable balance between cultivation and nature.
"My father and grandfather inspired them to grow their own food, and they learned their gardening techniques by reading OG," says Anthony Rodale. "This farm has a very special relationship with them."
Diversity in the Garden
When you stroll through the demonstration garden at The Rodale Institute, you are likely to be struck by two things: the wide diversity of plantings and the simplicity of the techniques used. The gardens demonstrate not only that organic methods work but also that they are not complicated.
In the early years, that wasn't always the case. The staff laboriously double-dug beds, added copious amounts of manure, and controlled pests and diseases with insecticidal soaps and hot pepper sprays, says Eileen Weinsteiger, the chief gardener since 1973.
"If we've learned anything over the years, it's that Organic Gardening can be very simple," she says. "Oh, you still have to weed and do some work, but we've abandoned many of the practices we once thought were necessary."
Many visitors express surprise at the light touch applied by the staffers. And they marvel at the integration of hundreds of food plants and ornamentals, the array of colors and aromas, and the rich bird and insect life within the dozens of raised beds.
"There's a lot of good news here for gardeners," she says. "Put in a lot of plants, mix up your flowers and vegetables, and enjoy."
Biological controls: Institute gardeners still use BT (Bacillus thuringiensis) against cabbage loopers and against Japanese beetles, but that's about it. The days of using rotenone, pyrethrins, and other botanical insecticides are long gone. There's simply no justification to use anything that kills good bugs along with bad bugs, says Weinsteiger.
Most diseases and insects can be controlled with row covers, diverse plantings, borders that are attractive to beneficial insects, birdhouses that bring in insect-eating birds, and simple handpicking, she says.
Diversity: No single plant type dominates any of the raised beds. Such diversity limits the spread of diseases and bugs. And many of the flowers draw beneficial insects, such as lacewings and lady beetles, which protect the food crops.
Wildlife: Insects, toads, and birds thrive here. Lured in with birdhouses, a bog pond, and lots of plants that provide habitat and food, they're all part of the diversity and natural pest control, says Weinsteiger.
"The wrens, especially, are really effective in keeping down the cabbage loopers," she adds.
Fertility: Years of composting have created rich planting beds. Organic matter makes up 5 to 10 percent of a typical raised bed at the Institute.
When planting, staff members dig down 12 inches, turn over the earth, and simply rake it smooth. During the growing season, they apply 1 to 2 inches of compost. The garden also makes extended use of cover crops, such as red clover, oats, and buckwheat, which return fertility to the soil.
Compost: The Institute promotes the use of plant materials—grass clippings, leaves, and garden waste—to make compost. It no longer uses manure in the demonstration garden (though it does in the farming trials) because most home gardeners don't have access to it, and they don't really need it, says Weinsteiger.
"Just use what you have. Everybody has access to plant materials from the yard and garden, and vegetable matter from the kitchen," she says.
