Japanese Maple
Japanese maple is a small deciduous tree with deeply lobed leaves and many cultivar forms. Dappled shade and evenly moist, well-drained soil suit it; leaf color and growth habit depend on cultivar.
Profile
- Foliage
- Opposite, deeply lobed leaves; color varies with cultivar.
- Form
- Upright and weeping cultivars occur.
- Exposure
- Excess sun, drying wind and drought can cause leaf scorch.

Species and soil references do not establish universal moisture targets, monetary appraisals or pest diagnoses. Missing pest lists mean evidence has not been verified, not absence of pests.
Water & soil context
- Moisture (VWC)
- No universal numerical VWC target established; calibrate to soil, sensor placement and root-zone conditions.
- Salinity tolerance
- No profile-specific salinity rating retained without direct evidence.
- Drought tolerance
- Depends on identity, establishment, climate and soil; do not infer an irrigation threshold from drought tolerance.
Check moisture in the root ball and surrounding soil; avoid persistent saturation. Adjust irrigation to measured site conditions rather than a fixed percentage.

Problems to watch
No species-specific list verified in the cited references. This does not mean absence of pests or stress; investigate changes with a qualified specialist.
