Why Are the Leaves on My Rubber Tree Starting to Curl?
I have a rubber tree in my lounge. I check the soil often to see if it needs watering and only water it when it starts to get dry. I use leaf shine wipes to clean the leaves, but only once every 2-3 months. I have just noticed that a couple of the leaves have started to curl their sides under. I just wondered why this was. Is it anything I've done or not done?

This can happen for a few reasons, all involving water in one form or another. A rubber tree that is underwatered or overwatered will curl its leaves. As will a rubber tree that is in too low of a humidity.
This time of year, it you just saw this behavior recently, it is likely a humidity issue. It is not uncommon that when the heat turns on, the humidity in the house drops. Try setting the plants on a tray filled with pebbles and water. This will raise the humidity around the plant and help to fix the curling leaves.
