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?

    I have grown hundreds of container citrus trees and meyer lemons are finicky. In general citrus aren’t terribly happy indoors where it is quite dry. I have mine in a greenhouse in winter where it is fairly humid and they all do great… except the meyer lemon which is never all that happy.

    I strongly suggest a non-meyer lemon. The grocery store types ‘Eureka’ and ‘Lisbon’ are great, and commonly available. Also Pink Variegated Eureka makes a pretty striped and pink-inside fruit, though less productive than the others.

    I have grown many lemon trees and they are all kinda similar (except meyer which is a hybrid)
