Watching grass grow- Week 3

"It had been startling and disappointing to me to find out that story books had been written by  people, that books were not natural wonders, coming up of themselves,like grass" (One Writer's beginnings, Ch 1) 

It is week 3 of the eco-lawn experiment and I sorely wish that the grass would just come up everywhere I had seeded.

There is a big bald patch in the middle, I wonder why. The initial thought was that the grass was growing well around the sprinklers. But during this past week we had unseasonal rains and temperatures that dipped at night to below the 50's very consistently.

We are planning to wait a couple more weeks before we re-seeds again in the bald patches.
