BENT GRASS: 4.5 – 6.8 lbs. of nitrogen per 1,000 sq. ft. per year applied in multiple applications of 1/8 to 1/4 lb. of nitrogen. Use higher rates in areas with prolonged growing seasons, areas of high use or “grow in” situations.
You have to use two herbicide separately. If then, you need to waste money and labor.
But, You can use one herbicide over bermudagrass and centipedegrass together. Caliente Herbicide will be answer.
Soil pH refers to the degree of acidity (sourness) or alkalinity (sweetness) of soil. The pH scale has been adapted as the measure of acidity or alkalinity. This scale ranges from 0 to 14, with 7 being neutral. Numbers below 7 are acid, above 7 are alkaline. All plants have a particular range of pH in which they grow best. At pH values higher than are optimum for a particular plant, fertilizer in the soil can not be properly utilized. High pH is very common in Florida soils, particularly along coastal areas. This problem shows most often in “acid loving” plants such as Azaleas, Camellias, Gardenias, Holy, Ixora, Magnolia and certain grasses such as Bahia. High pH usually shows as yellowing of foliage or an iron deficiency.
Don’t leave the Tree leaves. you can’t grow healthy turf grass under a mat of tree leaves.
Many turf pros make two fertilizer applications to prepare turf grass for winter. They schedule one in late August or September to aid in recovery from drought and heat stress, and another in October or November. Fertilizing turf grass in the late fall keeps it greener than unfertilized turf grass during the winter, and speeds spring green-up by two to six weeks. The enhanced rate of spring greening occurs without stimulating excessive shoot growth, in fact, far short of what takes place with early spring fertilization. Early fall and winter boost of fertilizer will cause the grass to continue growing and thicken (as you know “winterizing”).
One concern with preemergence herbicide use is timing of application. In a typical year, the earliest germinating crabgrass may be killed by subsequent frosts. However, in order to be effective, the preemergence herbicide must be applied before the first crabgrass that germinates following the last frost. It must also be activated by either rainwater or irrigation after application. Typically, they are applied two to three weeks earlier, when an indicator plant, such as Forsythia in the northern United States or dogwoods in South, bloom.
