SOIL PREP
Universal Plant Needs
Although garden plants hail from all corners of the world, they have surprisingly similar soil requirements — best attended to before planting. Simply put, most garden plants need soils that are well-supplied with air (yes, roots must breathe!), water, and nutrients. And one other important ingredient, organic matter (sometimes called humus), that witch’s brew of living and once-living organic materials in various states of decomposition that, in addition to contributing to the just-mentioned needs, also includes a friendly microbial community for optimum plant health.
Aeration must be the first consideration, since plants are unable to utilize nutrients, even in fertile soils, if roots lack access to air. There are two causes for waterlogged soils: either the water table is too high, bringing water up from below; or the soil has pores so small that they cling by capillary action to too much water that falls from above.
Deal with a high water table by either choosing another site for planting, by raising roots above the water table, or by lowering the water table. Growing plants in raised beds is the way to bring roots above a water table. Build beds high enough to take the roots up out of the water, and wide enough so they don’t dry out too quickly. Read more
