What type of fertilizer needed for centipede?
Question:
Answers:
Centipedegrass prefers infertile soils. Excessive use of nitrogen fertilizers can promote decline in this grass. Two annual applications of nitrogen at a rate of 1/2 to 1 pound per 1,000 sq. ft. are the general recommendations. It does make a difference where you live and when you fertilize Centipedegrass. Check with your local extension service for the specific application times and rates that are best for your area. Long term use of a balanced fertilizer (like 10-10-10) high in phosphorus should never be recommended for turf. The Texas Extension Service states that you should "avoid continuous use of a high phosphorous fertilizers since it contributes to iron deficiencies in centipedegrass". The Illinois Extension Service says of high phosphorus fertilizer use that "excess phosphorus may lead to potential runoff problems and more weeds in the lawn". Centipedegrass's low fertility needs and high iron requirements suggest that you use a fertilizer with a low N, Low P, high K ratio and added iron. Look for a fertilizer that has a range of ratios between 1-0-3 to 3-1-2. Where centipedegrass develops chlorotic conditions (yellowing leaves), supplemental applications of iron sulfate or iron chelate may also help. Monthly applications of iron help to maintain a greener color lawn. If soil pH is above 6.5 on a sandy soil or 7.2 on a heavy soil, elemental sulfur may help to lower pH and increase iron availability. Soil test information should be considered to determine the amount of sulfur to apply. Sulfur applications should be made in the spring and fall on heavy soils. Annual or less frequent applications may be adequate on sandy soils.
for the insect? I don't think centipedes need fertilizer. Do you mean insecticide?
Wow...never heard of a centipede lawn. I'll have to look that one up.
Centipede lawns do not require much nitrogen during the year (only 1/2 to 1 pound of actual nitrogen per 1,000 sq. ft).
You can apply a balanced fertilizer such as a 10-10-10 at a rate of 5 pounds per 1,000 sq. feet twice a year.preferably now and again 60 days later.
Please keep in mind that Centipede grows best in acid soils having a pH between 4.5 to 6.0 with an ideal pH being 5.8.
Do not apply lime or any material that raises the pH unless a soil test recommends it. If a pH change is recommended, lime can be used to raise thepH and aluminum sulfate or elemental sulfur can beapplied to lower a pH.
Hope this information helps. GOOD LUCK!
