Excerpts from Waller (2001)
"Flowers are also grown and the most important are orchids, the cultivation of which dates from 1970. One of the orchid farms was relocated from Mandai. Two of the farms survived for a few years, and then ceased production because the owners did not break even.
However, in the past year another, smaller scale orchid farm has been established at the site of a boat building yard at Sungei Mamam. This farm also has caged birds such as peacocks, and serves drinks on weekends."
[Editor's note: This is the Orchid Farm at Sg Mamam owned by headman Lim Chye Joo's son, Lim Chu Zi.]
"A duck farm on the island failed and so it seems that farming at Ubin is not easy but almost all the homesteads grow fruit and vegetables in their gardens for their own use, and this adds to the charm of the island."
