The triple-digit heat took a break and also brought us some clouds and breezes this weekend, so I finally got myself out back to weed and prep the overgrown raised beds. I worked in our homemade compost into the existing soil with my hands (and have the roughed-up skin to prove it) and re-set the drip lines. I also let some of the horseherb stay because it seems to serve as soil-cooling "mulch". I also left, for now, the stressed, but generally okay pepper plants, basil, oregano, sage, and thyme.
I sowed the following seeds to transplant as soon as they're ready: romaine, butterchrunch, and mesclun mix lettuce; swiss chard, kale, beets, carrots, dill, cilantro, broccoli, sorrrel, and spinach. I still want to add some fall annual flowers into the mix, too!
I think I've discovered what's preventing this mexican feathergrass from thriving.
