– If grass seed requires such specific care and constant moisture/watering for 7-10 days to germinate, how does it proliferate in nature with such onerous needs?

Answer 1

The problem here isn’t grass – it is lawns.

Grasses can be divided up into two groups called C3 and C4 which refers to the way that they do photosynthesis. The latter has evolved to actually use very little water to deal with higher temperatures and dry seasons.

Which works quite well and is a big part of the reason it has managed to claim such vast regions of the earth – but that doesn’t guarantee a nice even spread of the plants, especially outside of their natural habitats
