Acer palmatum
treeZones 5–9deer resistantElegant ornamental tree prized for delicate, deeply lobed foliage that turns brilliant crimson in autumn. Graceful branching structure provides year-round architectural interest.
Remove any dead or damaged branches from winter. Cut back to healthy wood at a branch collar.
Apply a slow-release balanced fertilizer (10-10-10) around the drip line. Avoid high-nitrogen formulas.
Water deeply once per week during dry spells. Avoid overhead watering which can cause leaf scorch.
Inspect undersides of leaves for aphid clusters. Spray with strong water jet or insecticidal soap if found.
Add 3-4 inches of organic mulch around the base, keeping it 6 inches from the trunk to prevent rot.
Gently brush off heavy wet snow from branches to prevent breakage. Do not shake branches when frozen.
