So far she has made over 1000 to be given away, being funded by the district health board's Maori Health Directorate.
A burial garden would give families a meaningful area to inter placenta, a place to make future visits and allow the burying of placenta in a "natural and environmentally friendly way".
It is proposed to hold a burial ceremony once a year with landscaping done instead of planting a tree with each placenta. This would avoid emotional upset if trees became damaged or diseased.
As the proposed garden has not been allowed for as a budgeted item, it would need to go through the Annual Plan process with the yearly costs estimated at $5000 with extra money needed for advertising the annual burial day.
The council's community facilities manager Andrea Jackson said GPS co-ordinates would be recorded for the designated area "to protect future plantings" and that the burial area would not be regarded as a memorial garden.
"There will be no memorial plaques or anything similar allowed in the garden, it is important that the area would not be similar to a cemetery," she said
Once a yearly planting was done that area would be closed to future plantings, meaning it would not be possible to plant siblings together.
In Nelson the city council created a burial site on Botanical Hill in 2008 and about 60 families bury placenta each year.
