More Is Better

Now that the greens have begun to actively grow, the areas in which Poa Annua was lost to Crown Hydration are easily identifiable. We are fortunate to have relatively small populations of Poa on our twenty five year old greens.  This has resulted in small circular areas of damaged turf that can be more quickly re-established than larger sprawling areas of  turf loss.

Aside from increased fertility levels and the use of PGR's to promote  increased tillering many of these spots have been overseeded with Bentgrass. Full scale broadcasting of seed has taken place throughout the greens with even more specific work being done to the small spots.  The seed that was broadcasted was spiked into the soil surface to increase soil to seed contact which is vital for germination.  On top of that a divot mix that included Bentgrass seed was also applied to these thin areas to further improve the germination likelihood.  This sand mixture also serves another purpose in keeping the green surface smooth because some of these dead Poa areas are slightly sunken below the turf line.

As existing Bentgrass moves laterally and germination of new seed occurs the putting surfaces will still roll true even though adequate turf might not exist.
