In order to plant the tree you need to use the Pine Cone and plant it with Right Mouse Button. If it says that you cannot plant the tree, the only reason can be the turf on which you do that. Some turfs do not allow the player to plant trees, grass and twigs. For example, Rocky Turf.

Hope it helps :)
