1905年,靠著出版童書的收入以及姑媽的遺產,她在靠近湖區的一個稱為近薩維里(英語:Near and Far Sawrey)的小村莊,買下了丘頂農場(英語:Hill Top, Cumbria),此時此處仍處於蘭開夏郡轄下。在接下來數十年間,波特買下了許多農場,以保護當地獨特的丘陵鄉村景觀。1913年,也就是波特47歲之際,她與賀德威克(英語:Hawkshead)當地的著名律師威廉·海利斯(William Heelis)結婚。波特曾因培育出賀德威克羊而得獎,也是一位致力於保護環境的熱心農人。她此時仍持續寫作與繪畫,並為英國出版商沃恩(Warne)設計基於波特童書作品而來的相關產品,直到因地產管理的責任加重與視力減弱,才無以為繼。
