6' Lemon

Meyer lemon trees thrive in full sunlight, requiring 8-12 hours of direct sunlight per day, preferably from the southwest, whether indoors or outdoors. 

Citrus trees need soil that is moist but not wet to thrive, especially if they are grown in pots. The best method is to water deeply but infrequently. Water when the upper two inches of the soil is dry. You can test this by pressing your finger into the soil down to your second knuckle and seeing if the soil feels dry or moist.
