Don't Top a Maple to Control Height

You planted a maple to brace a retaining wall and wonder if topping will make it wider instead of taller.

Answer: No—Topping Likely Kills It

Topping removes terminal growth, starves roots, invites decay/borers.
Maples are large trees; if space is limited, replace with a shrub or small tree (e.g., serviceberry, Japanese maple, viburnum).

Don’t top. Choose the right plant for the space.
