re: lime and fertilizer for grass

The only fertilizer that should be applied in the fall is potash. Muriate of potash, 0-0-60, may be applied in September or October to provide increased cold tolerance. Apply at a rate of 1-2 pounds per 1000 square feet. For extra color on fall turf, apply a foliar iron spray. This will help extend greenness into fall.

Fall is the best time to get your soil tested by the LSU AgCenter. Soil testing is the first step to a beautiful lawn and is the best way to determine exactly what your lawn needs to become thick and healthy next spring. Soil samples should be 4 to 6 inches deep as well as a composite of samples collected from several locations in the lawn. Mix this well and take a pint to your local extension office.

Results will be sent to your home address and/or emailed in about two weeks. Sample results may indicate that lime is needed to increase soil pH. Fall/winter is the best time to apply lime since it takes several months to react with soil and adjust to proper pH.
