yep, it’s virtuous.
Cedar mulch is acidic. It can help convert alkaline water (most city water is) into water much nicer to roses, rhodies, evergreens, and most flowers. I’ve observed that many of the plants that we call weeds actually thrive in city water, and don’t like cedar mulch. Pecan hulls, if you’re in the South.

I spent my morning (because it’s a rare cool day) helping Jane mulch the side of the yard, near the street. The mulch will discourage weeds, protect roots of the junipers and hemlocks, and generally give the place a nice “I meant to do that” look: it also holds water on the plants, and, being insulating, prevents the sun from evaporating water from the soil, and prevents the soil overheating. It also makes any weed that grows through it a little easier to pull, because it prevents the ground compacting into a brick around plant roots.

We moved one big rhody, whose leaves had curled inward, and discovered its roots had never left the original rootball: it was too hot. So we have now applied Wilt-Pruf to its leaves, topside and underside, and hope that we may have saved it by moving it to the cool shade at the corner of the house. Apparently evergreen rhodies, which have a lineage as old as roses and redwoods, have evolved a response to temperature that involves curling the leaves to protect them. So this was a distress signal, but we hope it will recover.

Outside of that, we have cleaned up the pond area, which had gotten a bit cluttered with weeds, and I have shoveled about a yard of mulch. More to do. Much more to do. But we hope the mulch means the side-yard is finished.
