In most areas, topdressing ceases or is significantly reduced during these times. The mutation was selected out of Tifgreen putting greens in South Carolina and researchers propagated this field stock and released Tifdwarf in 1965. courses indicate that TifEagle needs 8 to 10 hours of potassium levels on soil reports and maintain high Monitoring organic matter content through regular testing is a great way to understand trends over time and allows managers to make more-informed decisions regarding aeration intensity and frequency. lbs/cu.yd root zone mix Use dry bagged sand if of sprigs.
