Topiary - Trees and shrubs like ivy, holly, bay tree, vines and many other evergreen trees can be properly sculpted and converted to ornamental features into backyards. This work of sculpting trees and vegetation are known as topiary. Topiary can be carried out not limited to gardens spread over a large area but can also on in house plants. Generally fine mesh or wires are being used for topiary both indoors and outside the house. All that is required is a bit of creativity for topiary to be always a great garden idea.
