Doomed?

What are the chances of these two, little guys lasting longer than this summer? Not good, I'm guessing.

Surrounded by towering highrises, these two are tucked in a little block across the street from my own towering highrise (blocked in this photo by other towering highrises). In case you're wondering, I live in an area called The Condo Canyon. I think someone looking out one of their living room windows gave it that name.
