Please tell me whether it is necessary to shelter a tea tree for the winter? thanks.
Are you sure you really have a tea tree? It is often confused with myrtle trees with a variety of varieties. It is impossible to determine this without a photo. Therefore, it is difficult to answer your question. If you need effective advice, then upload a photo of your tree. This I mean, if you have a variety of myrtle, then there is another care. If you are lucky and you really have a tea tree, then you need to know that it is vulnerable to frost. Winters at a temperature of at least 10 degrees. It is also important to find out if it grows in open ground or in a pot on a windowsill.
