The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
When gardening near natural wildland-urban interfaces, one should take care to avoid planting invasive species, such as Cortaderia jubata (native to Argentina and the Andes) [2], Pennisetum setaceum (native to northeastern Africa and western Asia) [3], and Nassella tenuissima (syn.
