Lady Palm (Rhapis) Rootbound? Roots at Drainage Holes Not a Repotting Signal

Gladis' lady palm in 15-gal pot, watered weekly. Roots pushing on pot. Asks if repot now, what size, special soil/additives.

Roots at Drainage Holes ≠ Repot Signal

• Common misconception.
• If enough soil to keep roots moist 3+ days after thorough watering → no repot needed.
• If drying too fast → water more frequently, don't repot.

Maintenance

• If in pot 1+ year → standard fertilizer half-strength monthly.
• No other additives.

Photos welcome for further insight.
