What is the best rootstock for grafting walnut trees? Can you buy it or grow it yourself?

Answer 1

You shouldn't need to graft a walnut tree. They are very happy growing on their own roots - and usually do. I have never seen one grafted, at least.

If you plant a walnut, they sprout fairly easily but you have to be prepared to wait for between 8 and 12 years for them to fruit. It's just possible that if you grafted a twig from an older tree onto a maiden (first year) sapling, it would fruit quicker.

The Nut Farmer's website http://www.songonline.ca/opportunities/barkgrafting.htm should give you all the information you need.
