The 'Roar' hitmaker, who parted ways with her on-off boyfriend John Mayer in February, said she finds growing her own fruits and vegetables "relaxing", reported Daily Mirror.
"It's (gardening's) so nice, it's so fulfilling to go pick your dinner, bring it back and make it. It's relaxing and very fulfilling," Perry said.
The 29-year-old singer also likes to make sure that she absorbs nutrients and believes in drinking lots of fluids throughout the day.
"I take a lot of vitamins and I drink a lot of water," Perry said.
