Drought

Hello, insomnia. Might as well write out the thoughts.

I've been watching the "volunteer" trees that fringe the yard try to cope with the reality of drought this summer. A full-grown tree should not have wilted leaves, day after day. If I were still in Arizona, the tree would receive water by flood irrigation, but it's a foreign concept to people out here, and the yard isn't shaped to retain water. Instead, when it rains, water rushes over everything because we're at the bottom of the hill, then it drains into the sewer and is gone.

It did actually rain, a bit, over the weekend. The force of the storm ripped down half of one of the volunteer trees. It's currently resting against the neighbor's garage. I'm going to have to do something about that, and about the other recent large tree limbs that I've temporarily stuffed onto the compost pile. Probably just move them to the curb for green waste pick-up. I'm concluding that coping with branches is beyond my capability here, too, despite the desire to keep organic material as local as possible. Green waste pick-up stays at least reasonably local.

The oak trees still look all right, however. If they started showing signs of drought stress, I'd be more inclined to do something about it in their case, as opposed to the volunteer trees.

One of the improperly planted crepe myrtle trees that crowd the driveway is also looking the worse for wear. I don't know enough about them to know if I should bother with trying to do anything about it. Plus, the trees crowd the driveway.

The garden is holding on as well as one could hope for this time of year. I'd love to get mulch over everything, but that involves getting the mulch from somewhere, and I've been reluctant to spend all that much time out in the sun recently. It's still strange to me to consider strawberry plants as annuals.

I'm convinced that this is the book that gardeners here need to be reading, even though I haven't read it yet, myself.

around here it's technically illegal to build small dams to catch runoff and channel it into trees. But that doesn't mean we can't dig way too deep a hole for plants, and then not fill it all the way in. Or move gutters about such that the water has to run the very longest distance across the yard to escape.

The laws about rainwater catchment are strict in Australia, too, from what I've heard. I think they're one of those regions where water is so extensively managed that it's viewed as a public good, so preventing one's water from reaching public acquisition is seen as greedy.

Most rain garden designs don't lead to pools of standing water - they're basically extensions of the idea of getting water to soak in to one's yard by slowing its progress. Clearly a lot depends on local conditions! We tend to get fairly heavy, fast downpours here, and I think when that happens most of the excess water just winds up rushing down to the ocean in big bursts. I don't know for certain, though.

In most of the arid western states, yeah, it's more than greedy: preventing runoff is legally equivalent to theft.

Nevertheless, people tend to dig a lot of deep holes they fill with gravel, right in the path of where the runoff goes.
