At a recent visit to the beautiful Keukenhof1flower gardens in Holland,I learned about the practice of topping2.As flowers grow,sometimes the growers cut off the tops of the flowers,which they believe causes the plants to invest more energy into flower growth and less into seed production.The expected result is flower buds that will produce higher quality flowers.
