Soil Preperation & Garden Math

Virtual Course


The quality and make-up of your soil has a huge influence on how well your plants will do. Unlike sunlight, air and water (the other 3 requirements), you can’t tell whether your soils are right for your plants by looking at them, or sometimes even at your plants. Learn about soil structure, compaction, fertility and pH, and how you can modify these for a more successful garden.

How much mulch does it take to cover 500 square feet of garden 2 inches deep? Please show your work.” This lecture will remind you of those skills you thought you had left behind in 6th grade math.  It includes determining how many square feet of garden you have, how to translate soil test recommendations into actual numbers, and how much mulch to buy.
