Cloche (agriculture)

In commercial growing, cloches have largely been replaced by row cover, and nowadays are mainly found in smaller gardens.

[1] Parisian market gardens in the 1800s used 18-inch diameter bell-shaped glass jars (cloches) to protect plants in cold weather.

Notched wooden sticks were used to prop up and vent the jars on sunny days, and were placed back down on the soil before nightfall.

[2] "Chase barn cloches", introduced in the early twentieth century by Major L.H.

Chase, are constructed with flat panes of glass and held together by wires.
