Nurseries grow plants in open fields, on container fields, in tunnels or greenhouses. In open fields, nurseries grow decorative trees, shrubs and herbaceous perennials. They include retail nurseries which sell to the general public, wholesale nurseries which sell only to businesses such as other nurseries and to commercial gardeners, and private nurseries which supply the needs of institutions or private estates. A nursery is a place where plants are propagated and grown to a desired age. Plants may be grown by seed. The most common method is by cutting plants/plant cuttings. These can be taken from shoot tips or from roots etc. By these methods plants are grown in nurseries and gardens
