Schefflera New Leaves Turning Black: Root Prune and Light

If a 7-year Schefflera suddenly blackens new leaves, check roots: unpot, remove black mushy roots or, if root-bound, slice 1–2" off rootball sides and bottom, refresh soil, feed ¼-strength fertilizer monthly (skip Dec/Jan). Also increase light—Scheffleras thrive in full sun outdoors summer. Light is the primary driver.
