I had a discussion recently about the advantages and disadvantages of warmer climates vs. cooler climates. One issue that seemed important to me was related to horticulture: it has been my understanding that it is easier to build soil in cooler climates. In warmer climates, soil microbes work all year at breaking down humus. So if you add compost to your soil, it may last a few years where there is a short growing season, but last only a year where it doesn't freeze. Others were skeptical. And I have to admit that I don't have any hard data to back me up on this. And now I'm starting to doubt myself. Anybody know about this and can chip in a bit? Anybody had a garden where it's warm and a garden where it's cool?
