(2) Plant your lemon tree indoors during the cooler months. When the temperature starts to drop and you see frost on the ground, take the lemon tree indoors and place it in a solarium, patio, greenhouse or some other environment that still allows it to receive sunlight from a window. Ice kills lemon trees, so pay attention to the weather forecast to get him indoors in time.
Sicilian lemon trees are a great choice for those who will have to put the plant indoors. They produce a lot of lemons, but they won't get so big that you can't move them. They are usually 1.5 to 2 m tall, but you can prune them if you want.
