Best Windows

• February–March (ideal).
• Late winter/early spring before leaf-out (general deciduous rule).

Pruning Rules

• Cut to branch collar (¼" from trunk).
• Wounds >6": paint. <6": leave natural.
• Large limbs: 3-cut method (undercut, top cut, collar cut).
• Never remove >1/3 branches per season.
• Never top — creates weak, hazardous regrowth.
