Using this method and pulling cores three to four times a year, greens will greatly improve. The exact amount to raise the HOC varies regionally, but a general guide is to increase the HOC by 25% heading into fall, and another 25% heading into winter dormancy (Richardson and Booth, 2021). inch (3.2mm) or less. During active plant growth, a light verticutting may be done weekly. The first pass should be made in the most aggressive direction (down grain) and the second in the opposite direction, but on the same pass.

Use higher rates of N during periods of active Water requirements are similar to Tifdwarf.Irrigate immediately after distributing and cutting in sprigs. and faster greens speeds than TifEagle not treated with 3. Carbide-tipped blades are not ideal for this treatment. Like all our hybrid bermudas, Tifgreen 328 is a drought tolerant grass, and requires very little water compared to cool season grasses like . Fertility needs vary based on location and length of growing season, but common practices include a larger application of a slow-release granular fertilizer in late spring followed by spoon feeding small amounts of nitrogen fertilizer e.g., 0.10-0.30 pounds of nitrogen per 1,000 square feet every one to two weeks throughout the summer growing season. Once per month has not been satisfactory. A .gov website belongs to an official government organization in the United States. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. This practice also reduces the risk of winter injury, but on non-overseeded ultradwarf greens it is necessary to prevent speeds from becoming excessive during the winter months. successful when incorporated into the TifEagle management (Some superintendents have used higher levels Other important practices that will reduce the risk for winterkill include raising the HOC before cold weather arrives, applying a wetting agent before covering, keeping greens adequately irrigated throughout winter months, and following earlier recommendations related to plant protectants, growth regulators and aeration. prevention via methods mentioned above is preferred over The actual depth depends on the condition of the blades and the effect in the field. Winter applications help to reduce any surge in growth that may otherwise occur during a stretch of warm weather. her greens. Fertility: Nitrogen needs are less than 0.5 lb/1000sq ft (0.25 kgs N/100m2) 2 times per week growing slower, but once every week in the summer when The elements can be stressful to the toughest of grasses and no matter how good you are or how hard you try, its always going to be a challenge. 1. on the golf green.
