「My Favorite Apple Tree」 In winter time the ground is white, the darkness brings the long cold nights And blustery winds make drifts that are so deep The stars and moon put on a show, reflecting jewels in the snow While most of nature takes a peaceful sleep And my favorite apple tree looks as dead as it could be Without its leaves the branches are so bare And it's hard to think that soon branches once again will bloom 'Cause there is no sign of springtime anywhere. There's a hillside in the meadow it's a place I like to be It's a place where I can daydream and a place where I feel free It's a place where all the seasons color what I do and see While sitting in my favorite apple tree.When springtime finally comes around snow blankets melt and free the ground And everything stirs with the gentle breeze The sun and rain cause buds to grow and sap beneath the rough bark flows And soon the branches burst with fresh young leaves And the blossoms pink and round are like jewels in a crown When they open it's the sweetest smell I know And the buzzing of the bees is so soft up in the trees Without them fruit would not begin to grow. When summer finally does arrive the land is green and so alive And everything seems so content to be The nice warm showers and evening light the morning dew and days so bright All help to make a healthy apple tree When the small fruit starts to grow all the branches seem to bow'Cause they'll have such weight to carry 'til the fall And some worms are searching for the perfect apple core But I sure hope that they save some for us all. When autumn comes with crisp, cool nights the hillside turns to pure delight As all the world is covered with bright leaves The brilliant sun and deep blue sky, the sound of birds migrating by All help create a certain majesty And the apples red and sweet are a very tasty treat Every year I choose the biggest and the best And the deer all gather 'round eating apples from the ground But I hope they'll leave some for the cider press.
