When is the best time to trim spiral juniper trees in Wisconsin?

The best time to trim spiral juniper trees in Wisconsin is late winter to early spring, just before new growth begins. This timing helps minimize stress on the tree and reduces the risk of damage from winter weather. Additionally, pruning during this period allows for better visibility of the tree's structure, making it easier to shape and maintain its form. Avoid trimming in late fall, as this can encourage new growth that may not survive the winter.
