This list shows you the shared harvesting seasons of all Farm Together trees and the resource you get from them.

With the help of this list you can place the trees with shared seasonality close together so that you and your guests will have short distances between them during one harvest season.
This is also helpful in case you let your trees get harvested by your farmhands, so that they will always be busy until you relocate them for the next harvesting season.
And if you like to decorate your farm, like me, it´s easier for you to create mixed forests with different trees that are still easy to harvest.

This list also shows you the resource you get during the harvest - but NOT the profit either it´s money or diamonds.
It includes all DLC trees and the limited Events trees.
