The grounds of the Kew Asylum were originally landscaped in the tradition of an English country park.
 This was consistent with the Victorian idea that pleasant or beautiful surroundings would help ease the mental anguish of the inmates.
 It has been proposed that the initial plantings on the site were supplied by Baron Ferdinand von Mueller, director of the Botanic Gardens.
Initially, the grounds were planted with many conifers and large growing trees, oaks, elms and Moreton Bay figs; and trees indigenous to the area, river red gum, yellow box, and lightwood were retained in the landscape.
In 1913 the landscape gardener Hugh Linaker was employed to lay out the grounds of Mont Park Asylum.
As landscape gardener for the State Lunacy Department he commenced a program of landscape improvements and tree plantings at other asylums in Victoria, including Kew.

The conifer plantings and oak avenues along Main and Lower Drives were well established and of a mature size by the 1940s.
Conifers were widely planted from the 1860s along with Moreton Bay figs and occasionally oaks.
Oaks and elms were more widely planted from the 1880s.
It is not known if Linaker was responsible for the oak avenues, but it appears that many of the conifers, Monterey pines, Canary Island pines, Monterey cypress, hoop pine, Bunya Bunya pines and Himalayan cedars, predate Linaker and the oaks and elms may have been planted soon after his appointment.
The use of Bhutan cypress in the landscape is almost certainly due to Linaker as he favoured upright trees.
It is possible that the two remnant Monterey cypress along Main Drive and a Monterey pine along Lower Drive are trees from an earlier planting scheme.
 Several trees and plants on the grounds of Kew Asylum and Kew Cottages have been classified as of historical significance by the Victorian Heritage Council and the National Trust of Australia (Victoria), and have been protected during the property's redevelopment.

In addition to the asylum's ornamental gardens, the grounds featured vegetable gardens, farms and recreational areas such as cricket ovals and bowling greens.
 Little evidence remains of these structures except that there is now a road that encircles the former cricket oval.
