Hundreds, in my back yard, with my students at various schools, with my children at their schools and cub/brownie groups and beside my local creek. A meeting was once warned not to stand still beside me for fear of being planted.
I have a lovely pic of my daughter approx 2 standing beside a young Norfolk Pine she had helped plant in the local school grounds. They were the same height then........
I planted a tree a very long time ago. I was in primary school, it was for a special reason, but I don't recall what that reason was. I also recently planted some lavender in our yard with my husband. We planted it for the purpose of bonding.
When I was on 5 acres, we planted about 1000 Acacia trees -these were natives and for food for my llamas.
They ate them as soon as they had greenery on them, so we had to double fence along all the fence lines so they could not get at all parts of the trees.
I also planted mulberry trees, pear tree, and an orange tree.
When built house, planted trees around perimeter for shade & house protection. When left that house of 40 years' new owner chopped down ALL the trees!
Am very sad:( I loved the trees, & a variety brought the cheeky lorikeets to them. I loved listening to their 'chatter'!
In new area now, have planted a mauve 'Crepe Myrtle' & it's already flowered once, & only a metre high! Good little tree! Made me very happy!
