Apparently, to be a man, you need to plant at least one tree in your whole life. Regardless of your sex, and whether or not you care about such maxims, planting a tree and then watching as it grows can be an interesting experience! Imagine that you go back to the same place after 20 years and your tree will be already mature. And after 50 years? Sounds good, right?
Select the species of tree that you plant (you can explore them online) , find out under what conditions this tree can grow and buy seedling or order it on the Internet! Maybe plant a fruit tree? Imagine that you're eating an apple from the tree that you planted.
Now we need some free space for our tree. This can be your garden, plot or other legal location. Plant your tree and visit them from time to time! :)
