Juglans Family (Walnuts)The Black Walnut Neighbourhood
As some of you already know, many plants simply do not grow well when planted close to a walnut tree. The roots of both the black and English walnut as well as the butternut give off a toxic substance known as juglone which eliminates their competition. It will kill most evergreens, as well as some fruit trees and a number of vegetables. Most grasses seem not to mind, and some plants actually seem to thrive.
The following is a short list of some of the best neighbors for a walnut tree:
Black raspberries, Grapes, Rugosa roses, High bush cranberries, Black locust, Goumi, Persimmons, Paw paws, Mulberries, Currants, Elderberries, Sweet corn, Beans & Onions.
Some of the poorest choices include: Apples, Pears, Blackberries, Tomatoes & Alfalfa.

Nut trees, such as heartnut and pecan are very difficult to graft compared to fruit trees. Grafted heartnuts often start producing in 2-4 years. Early spring pruning is important for young heartnut trees to develop a proper 'central leader' type of tree form. Plant 2 different varieties for pollination or plant 1 seedling and 1 grafted tree.
A vigorous, hardy variety selected by R. Douglas Campbell here in Ontario, it is a reliable heavy producer of mid-sized, perfect heart shaped nuts. Mature height 8-12m (25-40')
