How to Get Rid of Bahia Grass in a Centipede Grass Lawn
Bahia grass (Paspalum notatum) is a type of seeded grass that has been associated with inducing many types of allergies, including hay fever. Bahia grass grows rapidly throughout many types of grass (including centipede grass) and will grow in a variety of soil conditions and climates. Bahia grass can be a challenge to eliminate because of its thick, deep roots, which need to be physically removed to kill it. If left untended, bahia grass may grow up to 75cm in height. Eliminating Bahia grass from centipede grass requires physical removal and spot treatment with grass killer. Killing Bahia grass is a time-consuming process, but it can be accomplished without a professional landscaper or specialized horticulture skills. Does this Spark an idea?
