 Weston was responsible for testing and selecting plant species at the arboretum for their suitability to Canberra's environment; from 1913 through to 1924 Weston oversaw the propagation of more than two million trees which were then planted in the Canberra area.Most of the original Westbourne Woods arboretum is now leased to the Royal Canberra Golf Club, with the remainder forming part of Weston Park.The Yarralumla nursery is still active, albeit on a smaller scale and functioning as a retail nursery selling both wholesale and direct to the public.
