While many gardeners don’t like dandelions because they don’t look pretty, the truth is that dandelions provide several benefits to your lawn. Their roots spread wide, loosening dense soil and providing increased aeration. Dandelion taproots can pull nutrients from deeper soil and deliver it to shallower plants. Dandelions actually provide excellent fertilization to grass and will reduce erosion. However, if you still don’t like your dandelions, there are methods for removing them.
