Bests & Worsts Reviews from Amazon

I have been gardening for 40 years and have read hundreds of articles and books on gardening. This one is "hands down" the best one I have read. Markham takes complex topics and explains them in plain english. For example, I now know exactly how to modify soil Ph with specific products in specific measure. I understand how each element influences the equation and why using a variety of soil amendments is advisable. I finally understand the value of Boron in plant physiology with smart ways to apply it. I now "get it" about what bio-char is, how to make it, and why it is important to my soil. I finally understand exactly why deep roto-tilling actually hurts the soil even though it "looks good" in the garden. Thank you Brett!
