I have this Meyer lemon tree in a pot. The leaves are slowly but steadily falling off, and each little lemon turns completely black and falls off before it even grows to like a centimeter or two. What could I be doing wrong? I have a soil moisture meter and I only water it when the meter reads “dry”. Could it be my grow light isn’t right or isnt strong enough?
Perhaps over fertilized?
I did that a few months ago on a year old tree, learned the hard way. Half the tree lost its leaves and new growth died prematurely. No fruit yet so can’t comment on that. I also had to trim the tips of the branches since they started to dry out. Luckily, a few months since, growth has restarted.
(My tree is outdoors so I can’t comment on light being a factor for an indoor tree 😬)
I just re-potted it and added fertilizer when I did that, so maybe that could be it. Is there a way to test for that so I know for sure? Soil PH maybe?
over-fertilization typically appears as leaf tip burn, I don’t think this is it
