* = Individual species fall mean rating significantly greater than corresponding spring mean rating. (P = 0.05)

 

zSod density and stability ratings were taken when undercut and after storage on a scale of 1 to 5 with 5=no seperation, full and solid root growth, 4=minimal separation, full and solid root growth, 3=minimal separation, root growth less dense, 2=minimal matting, slight loss of roots and soil, and 1=no matting, excessive loss of roots and soil, damage to plants.

 

yAppearance ratings were taken when undercut, after storage, and after replanting on a scale of 1 to 5 with 5=normal size, no damage to top growth, vigorous, healthy appearance, 4=normal size, slight damage to top growth, vigorous appearance, 3=normal size, slight damage to top growth, some yellowing of foliage, 2=undersized, foliage damaged, at least half yellowing and brown, and 1= undersized, foliage damaged, most foliage and stems yellowing and brown.

 

xunderlined numbers = flower present when undercut, stored or replanted.
