Answer: If your pear tree is mature enough, it will turn those flowers into fruit. If it is too young, it will flower but not produce fruit. If this is the case, you only need to wait a few years for it to mature. I'll assume your tree is mature enough to develop fruit. As long as the weather is warm enough, and insect visit the open blossoms, the tree will produce fruit. The temperatures between 60-70F sound perfect for fruit formation. Simply make sure your tree gets full sunshine all day, and water thoroughly when the top of the soil begins to dry out. It might help to have other flowering plants near your pear tree to help attract bees which will assure pollination of the flowers on your pear tree.
Best wishes with your pear tree.
