Columnar aspen and poplar trees are known for their slender, columnar shape and vibrant green foliage that turns golden-yellow in the fall, making them a popular choice for tight spaces or vertical accents in landscaping. Maintenance, including full sun exposure, well-draining soil, regular watering, and routine pruning, is essential for the health and beauty of columnar trees. We in Alberta are going though a drought that the trees are noticing, so frequent watering all summer is key. Watering times in late evening are best. When trimming these trees, ensure you have the right tools like sharp bypass pruning shears and also clean tools – not to be passing issues from tree to tree. Timing is crucial when trimming Swedish columnar aspen trees, with early spring ideal for removing dead branches, light summer pruning, fall cleanup, and major shaping during winter dormancy.
