The Christmas tree market in Ireland is facing potential decline as annual planting has decreased by approximately 50,000 trees over the past 15 years. Joe Flynn from Wexford Christmas Trees predicts a shift in household preferences towards plastic trees, impacting the balance between real and artificial options. Contributing factors include an aging workforce and new Brexit regulations that complicate exports. Despite these challenges, demand remains strong, with support from the Department of Agriculture aiding the transition for growers.
