Vegetable Forcing is a very important branch of vegetable gardening. Hundreds of acres under glass in the United States are devoted to the growing of lettuce, tomatoes, cucumbers, radishes and other vegetables. This is the most intensive type of vegetable gardening. It is often combined with market gardening, the glass being a great advantage in starting many early crops. Greenhouses, hotbeds and cold frames are employed for forcing purposes.
The production of vegetables in the home garden for the home table is often called kitchen gardening. On most farms the area devoted to this purpose is known as "the garden." Other parts of the premises may be manured sparingly or not at all, while this small area receives heavy annual applications. It is an Intensive type of gardening of greater importance than is generally appreciated.
