Update, Oct. 2016: At the end of a very dry year we have a fairly brown yard. I think we should recognize that there are two important reasons to let this normal event play out naturally. First the maturation and release of seed for many plant species follows a die back, and drying. Then the dropped leaves create an isolating layer which keeps the soil, and critters cool. Lastly, it is also helping to retain moisture in the soil. Here are some photos just before the predicted start of the rainy season. I'll also be posting updates as the rains return (hopefully) and the garden greens up again.
One way I judge our success is the number of critters that make this tiny patch of land their home. The latest are a pair of Western Fence Lizards, and a few Southern Alligator Lizards.
No photos of the W. Fence Lizards yet. They are fast, and paranoid. Good survival skills in an urban environment are speed, and fear.
