1) Height of cut – Height of cut is critical at Scottsdale golf club. We begin lowering the height of cut on all overseeded areas come mid-February and progressively lower throughout the following weeks.
2) Soil moisture management- Dry conditions equal poor Bermudagrass at a Scottsdale private golf course recovery during late spring and early summer. It is critical to prevent areas from becoming chronically dry as it will delay Bermudagrass transition.
3) Chemical removal- Many Scottsdale private golf courses use a variety of tactics to chemically remove overseeded Ryegrass without injuring the understory Bermudagrass. However, we must not wait until June to employ this strategy because much of the Bermudagrass may have already struck out. This tactic is much more effective when used end of April through May.
4) Nutrient inputs- Nutrient sources should be applied in coordination with chemically removing overseeded grasses at Scottsdale golf club. This will stress Ryegrass during warm daytime temperatures while providing nutrients for emerging Bermudagrass.
5) 100 Days Plus- It would be nice to give Bermudagrass 162 days of growth in the absence of competition from Ryegrass. However, 100-120 days is the guideline courses should keep in mind when planning overseed dates and timing chemical removal of overseeded grasses. If Ryegrass growth is retained well into June at Scottsdale private golf courses, the ability of Bermudagrass to develop the rhizome growth necessary to recuperate the following year will be severely limited. In other words, maintaining Ryegrass into June could result in a season-ending injury for Bermudagrass.
Growing two grass crops annually is a tenuous situation. Extending the Ryegrass growing season into June at the expense of Bermuda grass health is a season-ending injury.
