Signs of Overwatering
Yellowing leaves that drop across the whole canopy, not just the bottom, along with soil that stays wet for many days, point to root rot.
Signs of Underwatering
Leaves curl and drop, and any developing fruit can shrivel or fall prematurely if the soil dries out for too long during fruit set.
Adjusting for the Seasons
Indoor citrus needs the brightest spot in the house or, realistically, a grow light through the darker months - insufficient winter light is the most common reason indoor lemon trees fail to fruit.
Pro Tip
Hand-pollinate the fragrant white flowers indoors with a small paintbrush, dabbing pollen from flower to flower - without bees or wind indoors, this is usually necessary to get any fruit to actually form.
