Scalping can also be due to excessive thatch buildup. Thus, TifEagle is not recommended for collars. Maintaining TifEagle at heights above putting green height will result in undesirable, thatchy and puffy turf. that the topdressing material does not completely cover

This is done through frequent, light verticutting, which is usually done at a depth ranging from 1/32- deep. Mowing height should be gradually lowered to 0.140 inch

Unauthorized propagation is prohibited. A. Stimp meter tests have proved that Champion Dwarf greens are known to roll at speeds of nearly two feet faster than other ultradwarf varieties. One of the main differences between bentgrass putting greens and ultradwarf bermudagrass putting greens is the way in which they grow. Winter applications help to reduce any surge in growth that may otherwise occur during a stretch of warm weather. ), implement elimination procedures

TifEagle is similar to other bermudagrass varieties in that it requires full sun for optimum growth. TifEagle does not like heavy topdressing.

Light and frequent verticutting should be performed weekly. Again more frequent light applications of sand affect play less, and ensure that the most sand possible stays in the plant canopy and does not get picked up by mowers. 2 Superior Color Retention Under Cool Conditions Once temperatures dip into the mid-to-low 40's, Tifdwarf experiences chlorophyll loss and goes off-color quite rapidly. Other planting procedures.If TifEagle is planted as sod from plastic, sand based fields or washed sod, greens should be aerified with core removal after sod is rooted to minimize root zone layering. and we've got the research to back it up.
