Dethatching Season is off-and-racing at Turf Renos! Some regions have been largely unaffected by the big dry and have had a relatively good growing season. With the warm winter conditions experienced, areas are proving to have more thatch than previous years.
The Central Coast is an area experiencing higher than usual thatch accumulation requiring a double dethatching in order to remove the dead layer. This allows water and sunlight to penetrate the root zone more evenly, stimulating the soil microbial activity and exposing the sand slit drainage lines once again.
An incredible 620 cubic metres of thatch was removed from 4 hectares of a racetrack, whilst dethatching with 3mm blades at 50mm spacing and was cut at a height of 30mm. Surprisingly, almost as much was removed after the second dethatch going in the opposite direction, totalling over 1000 cubic metres of dead matter.
The track was then mowed in order to clip any uneven and long rhizomes that have been exposed from the dethatching process. This turfgrass maintenance all occurred with a relatively short rest and recovery phase and was completed in the early Spring season. This allowed for a faster track recovery so racing could recommence without delay only seven days later.
The track was then tined, fertilised and top dressed a couple of days afterwards and will be mowed down every few days to help strengthen and knit rhizomes together. This process will ensure resilience to tearing. The track is only allowed to grow in length for a few days before the race, to achieve 100mm in height. Shortly after all the racing fun, the turfgrass is mowed down again eliminating any wayward rhizomes from growing vertically.
Do you need a dethatch to keep your turfgrass healthy and on track this Spring? #turfrenos
