Memorial tree planted for former town mayor and governor in school grounds
Family, friends and pupils at a Sleaford primary school gathered to celebrate the planting of a rowan tree in memory of a former Mayor of Sleaford and environmental champion.
The tree was planted in the grounds of Our Lady of Good Counsel Catholic Primary School on Monday March 23 in memory of Ada Trethewey who died, aged 86, in April 2025.
Sleaford Climate Action Network were given a donation from the collection made at Ada's memorial service and have used it to purchase the tree for the grounds of the school where Ada was a governor for many years.
Members of Ada's family and Sleaford Climate Action Network were there, as well as some members of Sleaford in Bloom, of which she was chairman and a member for over 30 years.


Year 6 pupils and headteacher Paul Tibble also joined in the ceremony on behalf of the school.
Tim Grigg from Sleaford Climate Action Network, said: “Ada was a member for a couple of years and opened her garden to help raise money for Sleaford CAN. She came to events and helped with our snowdrop bulbs giveaway and seed swap.
"She was a great member of our team and so donations at her funeral were shared between Sleaford CAN and Sleaford In Bloom.”
One of Ada’s daughters, Sarah Pritchard, said: “Mum was a governor at the school for 25 years and myself and my siblings went to the school. Both my daughters went here too and planting something for mum is appropriate.
"It is really nice for mum and the generations of our family, with grandchildren and great-grandchildren here today.”
