Interest in growing their own food was increasing among Americans before the COVID-19 pandemic, but one analysis of Census Bureau and gardening industry sales data found an estimated 18.3 million people, most of them millennials, became first-time gardeners during the pandemic.

Some of those new and existing gardeners grew their vegetables in containers placed in sunny locations on decks, balconies and other open-air spaces. Almost anything that grows in the ground can be put in a pot.
The same frost dates apply. Some plants, like asparagus, can live and produce for 20 years, according to Harvest to Table, which offers practical guides to gardening no matter the setting.
