With all of the reactions on this site, let me say that we have and encourage a rather large orange tree and one 15 to 17 foot macadamia tree. Both are covered with bees during the flowering period. With the macadamia tree, that is about 5 to 6 months of the year as it produces about 4 crops each year. In addition, we have at least 8 to 10 humming birds visiting the orange blossoms. Doug
