5 year hazel cutting was used for wattling and hurdles, this is still used locally, logs ect you are looking for "dry" timber, or ash which you can burn green other wise you run the risk of over coking you flues and chimneys. To grow timber for logs you need land that you can leave for years to mature then use the fist thinning for burning this can take anything from 10 yrs depending the fertility of the land.
