Help. I only have 4 leaves left on my meyer lemon tree. I think it may be winter leaf drop. All the leaves were healthy looking, green and shiny, not wilting and the stems were still attached to the tree, just the leaves fell. From other posts it looks like winter leaf drop. My question is will my tree be dead if all the leaves fall or will it come back in the spring. First picture is two days ago, 2nd picture was 3 weeks ago. A couple months ago it started to drop leaves too. I had it in my sunroom and the temps started to drop so I took it in. I only had it for 2months at that time and hadn't fertilized any more than what was in the soil. I checked out some other posts on this forum. I then added a slow release fertilizer granules (Citritone) to the soil. I put it in the shower and gave it a deep soaking to flush it and fertilized it with general purpose Miracle Gro once a week when I watered it. I only watered it once a week when the soil, finger deep was dry. I put it in the corner to the side of my bay window (east facing). I did not put it directly in front of the window because there is a base board heater there and I didn't want to over heat or dry it out. I have it a couple feet away from the window and the heater up on a table. It started to look great, got greener and started to develop buds. I didn't change anything and a couple weeks later the buds started to dry up and fall off and some even fell off with out drying out. Once all the buds dropped the leaves started to drop. Once it got to the point in picture 1 I moved it to my kitchen window which is south facing hoping that it would help for it to have more sun. This is the only south facing window I have and tends to get a bit chilly in there. The temp at the window sill was 54 F and by the pot 62 F during the day. Not sure what it dips to at night. Probably not too much lower by the pot or the heat would have kicked on. Now I'm only down to 4 leaves. I moved it back to the same location it was in picture 2.
