1905年,靠著出版童书的收入以及姑妈的遗产,她在靠近湖区的一个称为近萨维里(英语:Near and Far Sawrey)的小村庄,买下了丘顶农场(英语:Hill Top, Cumbria),此时此处仍处于兰开夏郡辖下。在接下来数十年间,波特买下了许多农场,以保护当地独特的丘陵乡村景观。1913年,也就是波特47岁之际,她与贺德威克(英语:Hawkshead)当地的著名律师威廉·海利斯(William Heelis)结婚。波特曾因培育出贺德威克羊而得奖,也是一位致力于保护环境的热心农人。她此时仍持续写作与绘画,并为英国出版商沃恩(Warne)设计基于波特童书作品而来的相关产品,直到因地产管理的责任加重与视力减弱,才无以为继。
