I was recently given a number of walnut fruits and would like to try to grow them from scratch. Could anyone please suggest the best way to get the fruit to grow into saplings? I have been given various suggestions from including leaving them on cold soil until the frost cracks them, to bringing them on indoors over the winter and planting the saplings outside in the Spring. I live in Canada in Southern Ontario and would like to see them thrive in my garden. Any help would be gratefully received. Many Thanks
