The tree in the Masterton store has been set up near the Queen St entrance, next to the women's clothing department, and will be manned by hospice volunteers.
Hospice Wairarapa volunteer services manager Chris Wills said last year the tree of remembrance raised $8640 in three weeks.
This year, the campaign would be running for six weeks, until Christmas Eve.
"It's an opportunity for us to let people know about what hospice does but it's also a lovely way to remember those who are no longer with us."
Alternatively, Farmers shoppers can show support for hospice by purchasing a hand-painted bauble decoration for $10, designed by New Zealand artists Michel Tuffery and Letitia Lam.
Hospice Wairarapa does not receive any government funding and relies on donations and grants.
It provides free services and care to those living with a life-limiting condition, such as heart failure, motor neuron disease, multiple sclerosis or cancer, and offers support and help to their families.
Services offered include bereavement support, caregiver support, counselling and emotional support, as well as helping those ticking off their bucket list and documenting their life stories.
