If it get's "very little sunlight," it won't survive where you have it anyway. Didn't the "directions" say it needs full sun?

Chances are, it's suffering from not being watered while you were away. Newly planted grasses need to be watered every day at least. If you live where the current heat spell is happening, it's even more important.

Water it 2-3 times a day until the heat subsides. Then move it to a sunnier spot, and cross your fingers.

The tag said partial sun.....thanks for the info I am new to gardening..It does have a warranty for a year so I will try what you said and then see what happens!
