A website for gardening has published a piece on when and how to repot a rubber plant. The piece advises when is the proper time to repot. It recommends using a pot that is three to four inches bigger. Too large a pot can lead to the danger of the root rotting. The piece details how to trim the roots, put in the new soil, and how far deep the plant should go. The piece has a photo of a rubber plant.
- Repotting is needed if the tree root seems girdled, or growing around the sides of the pot
- You should pick a pot that is somewhat larger than the existing pot but not excessively large.
- Add a fair amount of fresh soil to the new pot and tease the roots.
“If you use a pot that is too much larger than the current rootball, the soil may stay wet for too long after watering because there are no roots in the added soil to draw out the water, which can lead to root rot.”
