BELL JAR - An old term and glass container which is bell shaped. On the top is a knob for the use of protection of a delicate plant. From the Victorian Era and now days known as a cloche.
Old-fashioned bell jars are an option for early-season frost protection.
The cloche or bell jar is a miniature greenhouse contraption designed to protect seedlings from cold, bleak, or windy weather in order to hasten their maturity.
The classic glass bell jars are still available but have some significant limitations. Because they are made from heavy glass and are small, the air trapped within can quickly get too hot on sunny days and possibly kill plants.
Jane shows some plants that have been grafted onto vigorous root stock and grown under bell jars. They will take after a couple of months and in a year or two they'll have enough wood to enable propagation.
AR - BELL - Place cuttings under a bell jar. The purpose is to protect the cuttings from drafts and to insure that a humid atmosphere is maintained around them.
