[1] After earning her certificate from the Cambridge School, Ireys went to work for Packer alumna Marjorie Sewell Cautley in New Jersey.

Out of necessity, she learned to do a bit of everything around the office, including typing, filing, cleaning, and errands as well as rendering, "inking," and visiting job sites.

[2] After Lowrie's death, Ireys pieced together a variety of jobs, from giving gardening talks on the radio and writing articles for newspapers to working in collaboration with Cambridge School alumnae Cynthia Wiley and Clara Coffey.

After the birth of her first child, Ireys closed the Manhattan office and set up shop at her lifelong home on Willow Street.

She borrowed elements such as terraces and parterres from large-scale landscaping and modified them for more limited acreage, emphasizing such features as serpentine walkways that created an illusion of larger space than actually existed.

[4] From the late 1950s until the early 1980s, Ireys regularly taught at the Landscape Design Schools run by the Federated Garden Clubs.

These schools educated garden club members in the principles of "good landscape architectural practice" so that they could "serve as guardians and critics of outdoor beauty in the U.S.A."[2] One major aim of the schools was to further the profession by educating potential board and committee members to advocate for professional planning of public outdoor areas.

Similar in format to her earlier works, it used a selection of Ireys' built designs to provide ideas and demonstrate principles for small and large gardens.
