My little lad was eating an apple two years back, when he took a bite and ended with a seed/pip in his mouth. After explaining what it was, he couldn't wait to plant it. So we banged a bit soil in a empty pot noodle tub, splash of water, put it on kitchen window sill. Must be 18" high now!!
Now my old lurcher bitch ain't much longer for this world, and when she's gone, I already spied a nice little place for her and the apple tree,s going on top. Then that tree is going to be worth getting sentimental about to me!!!
