Joel Rosen lives at Park Lake Farm in Mahtowa MN, in Carlton County. When we talked to him (on April 26th) freezing drizzle had put down a quarter inch of ice at the farm. "Whether weather like this is a setback to planting depends on your soil," Joel observed. "Light soil dries faster than heavy soil." In the 20 years Joel Rosen operated Park Lake Farm he kept records about the growing season. Those records are the basis for a spreadsheet he originally developed for the Duluth Community Garden
