Repotting a Large Ficus elastica: Pot Size and Stability

For a 170 cm rubber plant in a 23 cm pot, do not jump to a 38 cm pot. Oversized pots cause root rot by holding moisture too long. Max increase: 28 cm diameter.

Better Solutions for Stability & Watering While Away

1. Cache-pot method: Place current pot inside the heavy 38 cm pot; fill gap with gravel for weight without extra soil.
2. Reposition root ball: Center the trunk vertically in the existing pot.
3. Prune top growth: Reduce canopy weight (send photo for pruning guidance).

Watering every 2–3 weeks in a huge pot will rot roots. Stick to one-size-up repotting or the cache-pot trick.
