Thinning Overcrowded Cedars and Pines: When and How to Manage a Dense Screen

Fast-Growing Privacy Screen Becomes Congested

Jim planted young cedars and pines 7 years ago as a dust barrier along a gravel road. Now over 10 feet tall and tightly spaced, they look congested. He asks about thinning or transplanting.

Management Strategy

Transplanting Large Trees: Moving 10-foot conifers is difficult with low success rates. Not recommended.

Thinning Plan: Leave as-is for 3–5 more years, then remove every other tree. This maintains the barrier while reducing competition. The current congestion won't harm trees in the short term.

Timing: Spring or fall is best for any future transplanting, but thinning by removal is simpler and safer.
