Kochi man grows 40 varieties of mangoes on his rooftop

A man from Kerala's Kochi has been growing 40 varieties of mangoes on his rooftop. What started as a hobby for Puthanparambil Joseph Francis, a technician by profession, has now become a full-time passion for mangoes. He initially grafted a single mango tree for experimentation, and after tasting success, Francis now owns multiple varieties of mangoes which he said are sweeter than the ones available in market.
