Juglans Serr, Walnut - Pb40

Serr is very vigorous and large, and needs to be lightly pruned every year. Serr bears large, well filled, thin but strong shelled nuts on laterals as well as tips (nut bearing is evenly distributed between terminal and lateral buds). Its usual crop load is rated as 'fair'. It is an early leafing variety, so it is unsuitable for areas with late spring frosts.
