Ethan Mayes, interning with the garden department this summer, writes about Winterthur’s agricultural history and present:
When H.F. du Pont inherited Winterthur in 1926, the property could have been divided into two parts, the residence and farm. At the time, Winterthur farms not only supplied Henry Francis and the Winterthur community with food, but also supported the Winterthur livestock. In 1929, over 560 acres of alfalfa, ensilage, wheat, corn, and beets were planted purely with the intention of providing feed for the livestock. Winterthur livestock included 250 Hereford cattle, 100 hogs, 100 Dorset sheep, 45 horses, and 2300 poultry, and the renowned 450 head of Holstein.
Unfortunately, the farming operation was discontinued at the time of H. F. du Pont’s death, but in recent years farming operations have returned to Winterthur. Winterthur, in association with Greenbank Mill/Philips Farm, is participating in a sheep program. The sheep are located in the Negandank barn and surrounding pasture (visible from the main gate off Rt. 52).
Along with the sheep program, Winterthur has several fields of soybean and hay crops. The nitrogen-fixing soybean was planted at the end of May and will be harvested at the end of September. The hay is cut and baled twice a year. Although agriculture at Winterthur is limited to two crops at the moment, wheat, ornamental corn, and various vine crops such as pumpkins and gourds are in the works.
