Just got myself a little lemon tree! Besides the wonderful gift of getting organic lemons, lemon tree blooms smell absolutely divine. It has been such a pleasure having it inside. But since the sun has been baking away it was allowed out. We had frost last night and the tree was left outside for the night but has managed just fine! The tree flowers most of the summer and produces lemons all the way to late Autumn. I only take it inside again late Autumn when the frost is permanent.
