You can find live Christmas trees at various local nurseries, gardening centers, or home improvement stores during the holiday season. It's best to look for stores that specialize in Christmas trees, as they will have a wider selection and can provide more information about caring for your live tree. Some stores also offer delivery and setup services for an additional fee. Be sure to consider the size and shape of your space when choosing a tree, as well as the type of tree you prefer, such as fir, pine, or spruce.
