As of 2002, Mizil had 8 ha of green space, including roadsides and parks. Agriculture was a primary occupation for the town's inhabitants in the 19th and early 20th centuries, but is much reduced in importance as of the early 21st. Still, as of 2005, 1448 of the total 1931 ha are agricultural land, of which 89% is cultivated arable land, 7% pastures and 6% vineyards. Since 1990, the small tracts of land used for producing hay and growing fruit trees have been converted to other uses.
