  All gardens were censused in 2010. For a haphazardly chosen subsample of tillers ( n = 12) on each tussock, the total number of green leaves was counted and the length of the two longest leaves was measured from the top of the sheath. There were some tussocks with fewer than 12 tillers, in which case we measured all those alive. Old leaves that were initiated the previous year were identified by a dark band with dead tissue above it, whereas new leaves had no such band. A tiller size index was calculated by multiplying the length of the longest leaf by the total number of green leaves (usually 2, 3 or 4). This tiller index is highly correlated with tiller mass (Shaver, Fetcher & Chapin 1986).
