King Sago Houseplant: Brown Tips from Overwatering or Low Light

The Setup

A 2‑ft king sago in an east window in Maryland, watered when dry, fertilized quarterly with Palm‑tone. Some leaf tips brown.

Common Causes

• Overwatering: Sagos need fast‑draining soil; water only when top 2″ are dry. Water thoroughly, let drain hours, then wait until dry again.
• Low light: East window may be insufficient in winter. Supplement with a grow light.
• Cold drafts: Keep away from doors and icy windows.

Check for Scale

Look for 1/8″ white bumps on leaf undersides. If found, treat as in Article 1809.

Fertilizer

Palm‑tone is fine; apply only during active growth (spring–fall).
