Tucked away in the St.Croix River watershed of Wisconsin is the largest organic nut tree breeding farm in the country. Started in 1917 by Carl Weschcke, a nut breeder and head of the Northern Nut Growers for a number of years, the farm is comprised of hardwood nut trees from mountain ridges all over Europe and America.  Trees were grafted and cross pollinated, some were even patented.

Over 128 varieties of hard nuts are here including 19 varieties of walnut, 20 varieties of hickorys, 18 varieties of hick-cons,   hazel-berts, pecans, and chestnut. Endangered trees being preserved are the American Chestnut and butternut and hearth-nut. The breeding stock on this 140 acre farm is incredible.

Dan Carlson C.E.O. of Dan Carlson Scientific Enterprises Inc. bought the farm in 1989 and started using Sonic Bloom on the tree farm. Sonic Bloom makes any seed or cutting more viable than its parent. When the farm was purchased, the nuts were the size of a quarter, a few on the trees. Now after eleven year of Sonic Bloom, the nuts are now the size of a tennis balls, growing up to five at a time. The larger the nut, the better and faster growing the seedlings are. 

Also, when Dan started using Sonic Bloom on the farm, the leaves were the size of his pointer finger. Now the seedling leaves are the size of the palm of his hand. The larger the leaves the larger the fruit and the faster the tree grows. 


These trees and seedling are growing 500% faster than normal. Normally a black walnut trees grows 3/10ths of an inch in diameter a year. Ours grow 1.56 inches a year. So a tree that takes 50 to 80 years and can be worth $10,000 to 20,000 each, can now grow to maturity in 15 to 17 years. 250 trees an acre equals a lot of money (assumes tree spacing of 10 x 18 feet; close spacing makes the trees compete for sunlight and grow tall and straight).

It is a wonderful feeling to plant hardwood nut trees, endangered trees, and the most valuable veneer trees in the world.

These highest quality seedlings are for sale in quantities of 200 or more.  With your purchase, we include 10% more trees to assure you of a uniform orchard or plantation. Contact Dan Carlson at:
