Ficus lower leaves yellowing and falling off
Please help me. I have an indoor plant, a ficus (the kind with thin, long leaves), which I've had for almost 2 years now, and has been doing fine.
As of a few weeks ago, a high number of lower leaves have been turning yellowish and then falling off (something like 2-5 per day). The top leaves look fine, and in fact it looks like new leaves might appear soon (there are little "buds" at the end of the plant tips on the top).
Is this behavior a problem? What might the cause of the problem be? What can I do about it?
I have not changed anything in terms of watering habits. For a while, the room this plant was in had the blinds kept down (for about a week or so). I thought that was the cause (or certainly was not helping) so I fixed that, but it has now been a week or so since I pulled up the blinds and the problem is still there. Also, I repotted the plant about 3 months ago to a bigger pot (though I think I prob should have done that sooner according to the advice I got when bought it, they said to do within 6 months). But I am guessing it has not yet run out of room in the new pot (but that might be wrong?).
Please let me know your advice! thanks!
