If you buy a real Christmas tree this year, you will only be able to use it this year. You would have to dispose it after Christmas. If you intend to use it for subsequent years, then it would require heavy maintenance. You would have to spend a lot of time and effort just for the maintenance of the tree. There are no such hassles when it comes to artificial Christmas trees. They are perfectly suitable to be reused for multiple Christmas celebrations until they are completely worn out.
You might worry about the authenticity of the tree with regards to appearance when you use artificial trees. You might be concerned that artificial trees would bring down the impact of the Christmas celebrations. That may be true if you go for cheap artificial trees. However, your goal should be to get the most realistic artificial Christmas tree. It should be strong enough to withstand multiple years of usage. The tree that you get should be such that your guests should know that it is an artificial tree only if you tell them. They should not find out on their own by looking at the tree. You need to set aside a budget of at least 100 dollars if you wish to buy the most realistic artificial Christmas tree.
