Hello and thanks : planted three years ago at 7-8 feet tall, they are now ten feet, but thinning: I can see through them. Their branches have thinned from the bottom up, primarily starting on the sides facing southwest. Around the corner a neighbor's Norways are so thick no light passes through! What is the difference ? What can I do? Two arborists have come by. The first taught me that the hottest times of day are the afternoon, and SW is where the sun is, so...but I have watered them as directed, and doubt that is the major issue. The second told me I planted just a touch too high - that the roots are surface roots and mulch is good but it's not soil. But he said they would be fine ultimately. I added soil as he described. Last year I put in fertilizer stakes. They may have helped upward growth, but not thickness. 33 trees. They live with me a little SW of Cleveland.
