CitraBlue a new St. Augustinegrass for 2019

University of Florida Turf Breeder, Dr. Kevin Kenworthy will be releasing a new St. Augustinegrass cultivar called CitraBlue. CitraBlue will be a great addition to the warm season turf selection we have in the southeast. By the way, it is a cut above the rest. According to Dr. Kenworthy, CitraBlue has a striking blue-green color and has improved shade tolerance to Floratam St. Augustine, which is most commonly grown in Florida lawns. In addition, CitraBlue has a greater resistance to diseases such as gray leaf spot, large patch and take-all root rot. CitraBlue was bred and developed in Florida for Florida; this means that it is well adapted to Florida. In addition, CitraBlue handles shade very well, it also does well in full sun and has a dense canopy which reduces competition with weeds compared to Floratam. CitraBlue will become available in 2019. For more information on turfgrass contact Grantly Ricketts at gricketts@ufl.edu or 321-697-3000.

  1. Good morning Grant & fellow readers!

    The information is very exciting as well as good. What about drought tolerance? I understand that it is better than other SAF cultivars. Is there any information on the approximate amount of water it will require at the peak time of the year?

    Most SAF cultivars normally require around 1.35″+/- of water per week, but that will depend on the cultivar requirements, surrounding microclimate, and irrigation water application uniformity. Any information will be appreciated. Thanks in advance, keep up the good work.

    • CitraBlue requires less water but I cannot say how much. I have a strip of Citrablue in my yard among Floratam and it stays green during times of drought when floratam gets brown. I will ask the breeder for specific information on water requirement.

  2. Thank you Mr. Ricketts. This is great news. By the way, if I plant Citrablue plugs on my existing St. Augustine lawn which is not doing well, will CitraBlue eventually take over? How close should the plugs be to make this happen? Or do I need to remove the existing lawn?
