I live in Arizona so citrus is usually very happy here. I potted a dwarf lemon so we could bring it around with us when we move. I can never really get great advice on how to care for it regularly. It is about 3 years old. Last spring I finally saw about 4 flowers on it and 2 of them turned to small fruit in which eventually feel off before growing any larger. The tree now has a lot of the leaves turning yellow it starts with a pattern of yellow and then most of the leaf turns. The tree isn't totally covered in yellow leafs but it defiantly looks sad. Any suggestions would be great. I use a citrus fertilizer ever 2 months from Memorial Day to Labor Day. When should I repot it? I would love to see it thrive and have an abundance of lemons. Whatâ€™s the secret to happy citrus??
