The Know Lammas bread as Elven bread from the Lord of the Rings As with many Christian festivals the roots are probably pre-christian being based on the annual cycle. Philip July 9, 2020 at 9:46 am - Reply Yes always interesting the derivation of words. It is a term often used when cutting Oak trees but not other species. Oak can go through a number of rest and growth phases in the season, the last one of which is called Lammas growth. When cutting pollards or coppice, advantage is taken of this vigorous growth. If the cutting is done after 1st August (Lammas) the new shoots may not harden before Autumn and can often die back or get frosted. So an important traditional warning for woodcutters. Do it now or lose it. In contrast, Horse Chestnut only puts on growth until the flowers arrive early Summer, then growth is nil for remainder of the year.
