Seed Stage

• Pear trees, like all plants, originate from a seed. Many years will pass until the tree will bear fruit.
  
  

Sapling Stage

• A young sapling purchased from a local nursery is most often 2 or 3 years old, and will require a few more years of maturing to be able to produce fruit.
  
  

Bud Stages

• During the spring, the buds on the pear tree will begin to bloom. The first stage is the dormant stage. The bud, where the pear will formulate, appears to have no visible swelling at this point. The bud is brown and completely closed up. Next is the bud swell stage. Here, the bud swells as the fruit begins to develop inside. The light edges of the flower begin to be seen.
  
  

Flower Stages

  The bud burst stage is the first stage in which the flower is visible in the bud. In this stage, the bud finally opens and the flower emerges. The flower itself is still closed up. Next occurs the green cluster stage, in which the flower buds come into view even more from the original bud, and the white petals of the pear flowers are apparent. The white bud stage (or "popcorn" stage) follows, and the flower petals begin to open up, and swell to form a hollow ball, resembling popcorn. The bloom stage occurs next, and the pear flowers begin to open. The penultimate stage of growth is the petal fall stage. In this stage, the petals of the flower fall from the tree, leaving the buds from which the fruit will stem.
  
  

Fruit Stage

  The tree begins to bear fruit in the spring of its fourth year after planting. The fruit now begins to develop from the buds where the flowers first bloomed. Pears 3 to 4 inches in diameter are ready to be harvested.
