Potassium fertilizer could increase dandelions by 20x
Dandelion (Taraxacum officinale) abundance can be increased by potassium (K) and lime applications. Adding K fertilizer when it is not needed by the grass, or adding lime to increase the pH when the grass does not require such an adjustment, could lead to increased competitiveness of dandelions in that sward.
