One mountain grove can be a single living organism, with every white trunk sprouting from the same shared roots. That odd fact changed how I study autumn trees in Arizona, especially the ones lining shady canyon creeks.Color turns out to be a poor clue, because several species fade to the same buttery yellow each October….

A single palo verde can look bare in a dry spell and still be perfectly healthy. Leaves on these desert trees come and go with the weather, so the yard floor changes all the time. Not everything under the branches is a leaf, and that matters for reuse. Here is how Arizona gardeners can use…

A mum bought in October may have only a few weeks of mild weather left to grow roots. That small window matters more than most people expect. In Arizona, late fall and winter are not the same thing, and a plant’s chances can change between them. Before you dig a hole, it helps to know…

A mound that seems to pop up after a storm can make you wonder what just moved into your yard.

Most desert snakes are lousy diggers, so they borrow empty rodent burrows instead of carving their own homes.
