John Wise carries out his rainfastness work on grapes and apples at Michigan State University’s Trevor Nichols Research Complex, where he is coordinator of research.

Folklore says that after a heavy rainfall, you might as well get your sprayer out and reapply your insecticides. For those old twentieth century ­wettable [...]

Rootstocks, varieties, and tree training

  • February 1st, 2011

A research and demonstration orchard near Ferrara, Italy, is a horticulturist’s dream—a 25-acre plot to study rootstocks, varieties, and training systems for pears, apples, and cherries that’s funded by a private foundation without worry of budget cutbacks. And, how about a $3.5-million donation just for pears for the next [...]
