SALLY LEUENBERFGER, who might as well be called the Orchid Queen of Davao City, has a practical way of utilizing the portion of her 7-hectare farm that is not occupied by orchids. That’s by raising cattle. The animals keep the grasses low and the grasses that are cut from the area occupied by her orchids are also fed to the ruminants.The cows provide her good additional income.For instance, she has been selling them at P18,000 to P35,000 per head. She also has goats for meat. With the income from their livestock, they are able to continue their monthly grants in aid to their 25 national high school scholars from three schools in Tugbok, Maa and Davao City, according to Sally.
