hi there, much to my chagrin, one of my two meyer lemon trees is very sad. i only have a balcony with limited deck space and so one meyer is outside and doing very well. i live in northern california and it's fine. i received another meyer as a gift this august and i must say the tree never looked great. it was very tall (3-4 feet already) and the leaves were pale green-not yellow, but not dark and shiny. no blossoms or lemons anywhere. it finally got replanted into only a slightly larger terra cotta pot and brought inside (from the sidewalk, i couldn't leave it outside). it has been fertilized once in the 3 months i've had it with a special citrus fertilizer stick. i'm having two problems: 1. many leaves curling upwards, which seems to have stopped having given it a thorough watering. 2. MAIN PROBLEM: crazy leaf drop, they just fall when my hand grazes them. they are not turning color or even curling, they seem to have dropped initially from the lower branches and it's the uppers. the tree has lost 50% of its leaves in the past week since coming inside about 10 days ago. i'm desperate! my tree receives plenty of sun, i think, but our house is quite dry/drafty and can get down to about 60 or a little cooler overnight. i just started misting the leaves daily. i can't imagine root rot as the tree seemed to have not gotten enough water, thus the curling upwards. i also have quite a mess of what i think are fruit flies-any tips to get rid of those guys would be helpful. i've read many of your posts and cannot diagnose my problem. thank you in advance for any advice.
