  Enterprise Budget: Raspberries

  Raspberries are a favorite among consumers. This sweet fruit has become increasingly popular in the last decade with the United States as the world’s third largest producer. Washington, California, and Oregon are the leading producers in this country, but raspberries are suitable to grow in Iowa. Raspberry harvest begins in the early months of summer and extends into early fall. The first full crop from a raspberry planting will be harvested in the second year after planting.
  
  Commercial production of raspberries is a long-term commitment with stands usually lasting 10 years. Careful site and variety selection, soil preparation and irrigation are important in the planning process.
