Rubber tree losing all leaves
My poor 8.5 foot tall rubber tree is dropping leaves daily. Soon I'll just have tall rubber tree sticks. The leaves turn a pale yellow in the center before dropping and the new leaves, what few there are, curl under at the edges. Our house is very warm during the day, but does drop down considerably at night. We use wood heat and the air can be dry so I keep a pot of water on the heater to add moisture to the air. The tree did quite well last winter, but the house may not have been this dry but our winter is much colder this year. I thought I might be overwatering it so I cut back a bit, not too wet and not too dry either. This poor plant really needs help.
