I bought a Meyer Lemon almost two years ago and still have not figured out how to make the poor tree happy. It will start to leaf out and several times has even had flowers, then the leaves all fall off. I've tried everything from different pots to different soil to different watering schedules. Last spring I repotted it into a cactus mix and it started growing like crazy in my warm south facing window. It looked happy for about three months till I moved and it lost all its leaves again. It is now in a west facing window near a heater, but my house is still cold. I've been spritzing it with a spray bottle since my house is dry. I think I've finally killed it after it hung on for two years. The last leaf has fallen off. About half of the trunk is green and half is brown, but I am still determined to master citrus! Any tips to revive this guy are welcome, I've also ordered a new lemon tree (not Meyer). I will keep trying till I figure it out, but I would really appreciate some help! This tree really has me scratching my head! Experienced gardener, but I've never done well with indoor plants
