(More customer reviews)If you are wanting to use this fertilizer for it's stated purpose, and you live somewhere like southern Louisiana, and you have St. Augustine grass; STOP!!!!!!!
As it turns out, this so-called winterizer has a very high Nitrogen number and a low potassium number. This is the exact opposite formula that you should use according to the LSU agriculture center.
"To winterize Southern, warm-season lawns, apply a fertilizer with more potash than nitrogren. Potash is represented by the third number on a fertilizer bag, while nitrogen is shown as the first.
In the fall, the emphasis in feeding changes from growth to strength. In September, apply a fertilizer with less nitrogen to slow growth and more potash to build stress tolerance.
"Our lawn grasses are the warm-season type, so they grow when it's warm and not much when it's cool. That means we must encourage growth with nitrogen in warm weather and not push the grasses when we shouldn't," said LSU AgCenter horticulturist Dr. Tom Koske."""If we keep feeding a relatively high N in the fall, we will spur soft, lush growth," Koske said, explaining that soft growth is more subject to diseases like brown patch. This damage won't have time to grow out of it because the cooler weather and shorter days won't let it.
"Our fall lawn care plan should encourage only moderate, slow growth on centipede and St. Augustine lawns," Koske said.
Beware of northern-blend winterize's that have high N and moderate potash. Apply any fall fertilization in September. It is not needed any longer in October.
If you already have been applying about half as much potash as N, winterizing is not necessary. If you have been putting out mostly N this summer, apply a southern winterizer now or just muriate of potash (0-0-60) at 1 to 2 pounds of muriate per 1,000 square feet.
"If in doubt, it is better to do nothing at all than do the wrong fertilizer program at this time," Koske said. "
[...]I gave a low rating because the product's label is misleading. It should specify that it should not be used in southern climates.
