How does ammended soil tilled into the clay help trees better such as Eastern Hemlock or Canadian Hemlocks?
The word “clay” only refers to a particle size in the soil that is very small, flat, and tightly pressed together. The nutrients in clay soil will vary from place to place. Most “clay” soil really has other things in it than just clay, too – all soil is a mixture of clay, silt and organic matter, and sand, in various proportions. That said, any plant that I know of grows better with more organic material added to the soil; that’s just a given. Especially when you’ve just transplanted a new plant, this is good general advice – transplanting is hard on a plant, and you want to give it the best shot you’ve got. But why does your tree farm grow in TN? Well, no farmer stays in business very long if his crop doesn’t grow well at his location. Usually, he looks around and sees what others grow nearby, and what does best. Then, he goes into the same kind of business, maybe better somehow, or in his own special niche. Obviously, trees grow well in their soil, or they’d be growing something else
