Height/Spread: 'Wiethorst' typically grows to a height of about 3-4 meters (10-13 feet) with a spread of 1.5-2 meters (5-6.5 feet). Its compact size makes it suitable for smaller gardens or as a focal point in larger landscapes.

Position: In the Irish climate, 'Wiethorst' thrives in a position that receives full sun to light shade. It prefers a sheltered location, especially in regions with strong winds, as the delicate needles can be susceptible to damage.
