I have read many times and seen on tele not to plant the same veges in the
same soil year after year, even the old codger on Gardening Aus on ABC
mentioned it last week, but as yet I have not come across scipt or a
diagram on rotation: what to plant next etc, could anyone enlighten me,
Thanks in anticipation
