Rubber Tree Ficus elastica

Water

The rubber plant can be a bit finicky when it comes to water. If it is kept too wet, it will react with yellowing leaves that drop.
The same can be said of too little water.
When it is dry a few inches down, thoroughly water.
It will need less in lower light situations.
If it is in a large pot (over 12″) use a dowel or stick to help decide if the plant needs water. Put the dowel all the way down to the bottom of the pot and leave it there for a few minutes. When you pull it out, if the bottom of the dowel is wet, don’t water. If dry, water thoroughly.

The rubber tree would prefer bright light such as an east or west window would afford.
It can tolerate low light.
The variegated versions need to be in a higher light situation to keep its variegation.

Fertilize with a balanced fertilizer every fourth watering at 1/2 strength from March -September.

Wipe the leaves down with a damp cloth or sponge or shower often to keep the dust off the plant’s large leaves.
