Q.Ficus Tree Losing Many Leaves
I have had my ficus tree for about 10 years. This winter has been problematic as I tried to find good spots for all my plants with so little sun. I have moved my tree 3 times (!) which I know they do not like. Last week I moved it to its present location…lots of light but no direct sun. I use a water meter to see when the soil is dry. I use bottled water (no fluoride). I water thoroughly until I get water draining from the pot. Sadly, for the first time ever, it is losing many leaves. I don’t know whether I should fertilize it now or wait to see if it stabilizes.
As it’s about 5 ft tall, it isn’t easy to repot, but I will do so if necessary…but how do I know if now is a good time. Seems like it may be too much of a shock.
Any insight from you would be helpful.

I do think your tree would prefer to be left in one place for a while. If you have a grow lamp, it may appreciate increased light. Have you checked it for pests?
These plants do shed leaves at times, so just be sure any dead leaves are removed from the pot. If you haven't fertilized it for a while, it's okay to do so during the winter - just not as often. I think if you've found a draft-free, well-lit space, your best bet is to leave it alone for a while to let it acclimate. Here are a couple of helpful articles:
