Technically, dandelions aren’t bad for your lawn, and they don’t directly kill grass. In fact, they appear in areas that are nutrient-deprived, and their long taproots can loosen the soil and bring nutrients closer to the surface. 

However, dandelions do spread quickly, and they can take over your lawn, eventually crowding out grass. This is why a healthy lawn is the best defense against dandelions.

Yes, if your home is poorly maintained and has weeds and overgrowth, it can affect your home appraisal and lower the value. Home buyers want to see a well-kept home, and if yours lacks curb appeal whether inundated by weeds or not, you could be neglecting the potential for it to reach its full value.

Due to its slow growth, Bahia grass does not generally take over weeds. In fact, the opposite can be true. Young Bahia grass is susceptible to being taken over by weeds. 

Likewise, in the cool season, Bahia grass goes into a dormant state that can allow weeds that thrive in early spring to get the upper hand. If you want to prevent weeds from taking over your yard, remove them by hand or apply a Bahia grass-friendly pre-emergent herbicide to your lawn before weeds have a chance to appear.

Dandelions, while hard to control and widespread across the country, are not typically categorized as noxious. Yellow starthistle, however, looks very similar to a dandelion and is highly damaging to local plants and invasive across the country.
