"Those are what my son's children placed on their daddy when he died. My son's oldest boy said, 'Nanny, you can have these to sew on your tree'."
Ms Davison knitted for nine months and said she was waiting for her son to come down and help her finish and "do all the high bits so I wouldn't have to struggle on the blimin' ladder," but her daughter helped her at the finish.
"I think it's pretty cool," she said.
"I was so excited when it was finished. I gave my daughter a big hug.
"Because of my son's passing, it's been full on. I've been up and down, and that. But I'm all right. I'm going to have bad days every now and then. He never got to see my tree, I don't think he got to see any of it."
Ms Davison said she was inspired to yarn-bomb her tree after seeing a similar thing done in Rotorua.
"And I love knitting, I've had a couple of operations this year so I've had a lot of free time. I need to be keeping my mind busy."
Ms Davison said she likes to come out and look at the tree "quite often", with some of her favourite additions being three crocheted flowers that were made by her aunty Lorna Chapman, who passed away in May.
Ms Davison lives in Dover Place, Masterton, and encourages people to come have a look at the knitted creation.
She has called the memorial tree Quintessence, inspired by her son Quinton. Quintessence is defined as the pure and concentrated essence of a substance.
