"As the poet said, 'Only God can make a tree,' probably because it's so hard to figure out how to get the bark on"

This quote by Woody Allen is a humorous take on the famous line from the poem "Trees" by Joyce Kilmer. The poem mentions that "just God can make a tree," and Allen is recommending that this is due to the fact that it is so difficult to find out how to get the bark on. He is suggesting that the task of creating a tree is so intricate that only a divine being might achieve it. This quote is a lighthearted method of expressing appreciation for the complexity of nature and the power of God. It also works as a tip that some things are beyond our understanding and control, which we ought to fear of the charm and intricacy of the natural world.
