This wonderful little book covers everything you need to know about the types of plants known as weeds. Ehrenfried Pfeiffer discusses the different varieties of weeds, how they grow and what they can tell us about soil health. The process of combatting weeds is discussed in principle as well as in practice, so that it can be applied to any situation. First written in the 1950s, this is still one of the best overviews of the subject available.
Must be taken with a grain of salt remembering that it has a focus on agriculture/industry (and does not take into account 'native plants' of any areas except the one he is writing from), but fascinating info overall. Wish he'd said something about bindweed besides essentially 'it can really take over, bummer' before moving on
A primer on the categories, causes, and uses of weeds. This is a great read if you want to know more about weeds, even if you only have a small garden invaded by common weeds like docks or dandelions. The book helpfully arranges weeds based on the kind of soil they prefer, which in turn tells the farmer or gardener what problems the soil may have. Had the book also reiterated the kind of soil associated with each weed family at the beginning of that weed's chapter, there would be few other ways to improve it.
