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?
The light looks underpowered for the plant’s needs. Take a look here at the “lighting for indoor trees” section and compare those specs to the light you’re using. I’ve seen a number of inexpensive “grow lights” that don’t produce the necessary spectrum or lumens, so be sure to take note of the manufacturer specifications if you decide to replace your lights
