What type of root system do they have?
They have a deep tap root system. 17. How far apart should they be planted? The old strategy was to overplant and then thin out the inferior trees. With the genetically-superior black walnut trees, this is unnecessary. Also, planting fewer trees allows you to interplant with other crops. We recommend planting no closer than 20′ by 15′ for the grafts and 15′ by 15′ for the seedlings. 18. If the trees grow too fast, will the quality of veneer suffer? This is a common misconception, according to a study by USDA Forest Service’s Forest Products Laboratory. They found increased lignin, higher specific gravity, darker color and better tooling characteristics in faster-growing black walnut. Besides, it’s not the closeness of the grain but the variation that makes for a beautiful veneer. Therefore, speed of growth has little to do with how attractive it is. Moreover, many veneer and furniture companies prefer the more uniform quality of plantation-grown hardwoods to provide consistency through
