Here are excerpts of comments made by Coalition volunteers regarding the role that grass might play in retarding the spread of kudzu. We plan to consider ways of testing whether this is measurably true. If true, then we plan to consider how to make practical use of this very interesting observation.
You pointed out at the YMCA test plots this morning that you didn't have to remove any crowns on the rollback and redirect test plots. [T]he grass was there first and provided enough scaffolding to prevent the vines from setting new crowns. This is consistent with my belief that getting a grass and sod cover established early in the spring (March - April) in advance of the kudzu starting to grow in late May to early June can facilitate both control and eradication by minimizing kudzuís ability to set new crowns. The early grass works as scaffolding to keep the vines off the ground and limits the crown infested area.

My comments simply meant to suggest that maintaining the grass, mowing it regularly and cutting the encroaching kudzu in the process, is an optimum way to hold the kudzu back from advancing . . . Additionally, I would guess that a good grass cover retards kudzu rooting, that it will only root after it has sucessfully shaded out the grass cover.

. . . I think I have seen kudzu vines with about one inch roots extending downward, but not yet in contact with the soil. We have all seen small crowns sitting a half inch or so above the dirt. Let's be on the lookout. No telling what we will find.
