Now is the perfect time to be harvesting and collecting Hazelnuts (or Cobnuts) from trees and hedgerows in the wild. There are many different Hazelnut trees growing throughout the United Kingdom, especially in places like Kent, Dorset, Worcestershire and Devon. They are still grown commercially in many of these locations, though when cultivated or grown this way the nut is usually larger, and is referred to as a Cobnut.
