It sprouts when rain falls.
I live in a dry climate where there are lots of wild grasses. They sprout up in spring, when it is rainy, then dry out over summer, when it is dry.
Constant moisture for 7-10 days isn’t really anything special, in fact, the low moisture needs of grass relative to trees and bushes are what allows it to dominate dryer climates like grasslands and savannas.
