There are nearly 1,000 Christmas tree farms in Wisconsin. Many of them are smaller than 25 acres, but there are also some that have more than 300 acres. All of them grow trees in a sustainable way; they take care of the land and plant trees each year to replace the ones that were cut. Trees are grown for the purpose of cutting as a Christmas tree. They are planted in rows, about 6 feet apart, and taken care of each year, so they are beautiful when its time to harvest them. Just like other crops like flowers or pumpkins, they require attention and care in order to become a tree that you would enjoy in your home.
