Common Dandelion

With deep roots, these weeds can be tough to eradicate.

While there are a number of dandelion species in Texas, the common dandelion (Taraxacum officinale) is most often a problem for urban lawns. Dandelions are perennials that thrive in areas of full sun and consistent moisture, however they can still crop up in areas of drier shade. They produce a huge taproot that can reach up to 15-feet deep! Pulling the top of the plant off, or cutting it down with a weedeater won't kill the plant; it can generate new top growth from the roots below the soil. Seeds from the bright yellow flowers spread far and wide and can quickly overwhelm a weak lawn with poor soil.

You'll notice that the St. Augustine grass around this dandelion is dying out; it's very thin and stolons are dying on the soil surface. This area suffers from severe compaction and overwatering, making it the perfect site for a dandelion invasion.
