I created a 500 sq ft Dymondia "lawn" subsitute. I planted it one year ago this month. All has been well except lately I am getting some dead spots as well as dead trails. Is this a disease, fungus or something else??
This seems to be a mole or gopher related issue. This article should help: https://www.gardeningknowhow.com/plant-problems/pests/animals/mole-control.htm
