Full listing of what weeds can tell us about our soil

See previous post for my top three pics....here is the full list!

Barnyard Grass: Low calcium, low phosphorus
Beggars ticks: overly moist soil, possibly poor drainage, low calcium, phosphorus, humus, bacteria, poor decay, high phosphate, magnesium, aluminum.
Hedge bindweed: Improper decay of organic matter, excess of heavy metals, low calcium, phosphorus, potassium, pH.
Burdock: High iron and or aluminum, low pH, low calcium.
Carpetweed: Good calcium, balanced soil.
Chickweed: Good organic matter on soil surface.
Crabgrass: Low calcium.
