Q.Lemon Tree
My lemon tree we placed outside in a container had purplish pink flowers on it. They have now fallen off and no lemons. The tree is approximately 4-5 feet tall and 2 years old. It has never bore fruit. Please help. Did someone sell me the wrong plant?

Depending on the variety and the root stock it can take 3 to 5 years for a Lemon Tree to produce fruit.
