Overwatering on rubber plant
What's Happening
Overwatering in Ficus elastica is fundamentally a frequency problem rather than volume—the plant requires oxygen exchange at root level that cannot occur when soil remains saturated for 7+ days. The thick, leathery leaves mask early root decline, making rubber plants prone to severe root rot before above-ground symptoms appear. Contributing factors include: oversized pots that retain excess moisture, dense potting mix without drainage amendments, lack of drainage holes, and watering on rigid schedules without checking soil moisture. Unlike tropical understory plants, Ficus elastica evolved in seasonal monsoon/drought cycles and cannot tolerate chronic soil saturation.
How to Fix It
- 1
Confirm overwatering: Check soil with finger—wet below surface after 7+ days since watering = overwatering; heavy pot with wrinkled leaves indicates waterlogged roots not thirsty plant
- 2
Stop watering immediately: Allow soil to dry completely before any additional moisture
- 3
Inspect roots: Gently unpot plant and examine roots—healthy roots are white/tan and firm; rotting roots are black/brown, mushy, and foul-smelling
- 4
Trim rot: Remove ALL affected roots with sterile scissors until only firm white tissue remains; trim any soft stems at base
- 5
Repot in dry mix: Use fresh well-draining soil (50% potting mix, 30% perlite, 20% bark); ensure clean pot with drainage; do not water for 7 days after repotting
- 6
Recovery care: Maintain bright indirect light; wait for soil to dry completely before first post-repot watering; expect 4-8 weeks for full root recovery before new growth resumes
What You'll Need
How to Prevent It
Water only when top 2-3 inches of soil are completely dry—use finger test or moisture meter before every watering; ensure pot has 3-5 unobstructed drainage holes; use well-draining mix with 30% perlite minimum; match pot size to root ball (only 1-2 inches larger); avoid automated watering systems; adjust frequency seasonally—every 7-10 days in summer, every 14-21 days in winter; use terracotta pots that wick excess moisture through porous walls.
