Young Maple with Bending Leader: Patience Over Pruning

Assessment

A 4-year-old seedling maple with a bending central leader is normal. The leader hasn't "expressed" dominance yet; lower branches are vigorous but not yet hardened off. The tree looks healthy.

Recommendation: Wait

Do not prune now. Let the tree grow through another season.
Re-evaluate fall 2012 (after leaf drop) for structural pruning.
If needed then: Remove lower branches competing with leader; cut at branch collar.

Why This Works

Young trees need foliage for photosynthetic capacity to build trunk caliper and root mass. Premature pruning slows overall development. The bend will likely self-correct as the leader thickens and lignifies.
