Dierences in the underlying philosophies and goals
of community garden programs, as well as surrounding
environmental and social conditions, were revealed by
rules on chemical use and the sale of produce and by
fencing of community gardens. Overall, 60% of the
programs either prohibited the use of any chemicals or
allowed only chemical fertilizers to be used in gardens.
However, 60% of rural programs compared with 33%

gardens. However, approx. one half of the urban pro-
grams reported problems with vandalism, with no
dierences in the report of vandalism between pro-
grams that did and did not fence their gardens. One
