    Tilling the area will definitely help grind up stubborn roots. If the patch is small enough, then the best solution will be to pour boiling water over the area where the roots are. This will kill them immediately without making the soil toxic, so you can replant immediately.

    If you till, you will chop the roots into bits and each piece will try to regrow. If you hit these new sprouts with herbicide, it will kill them. But what about the deeper roots? These go down deeper than tillers and are the biggest, most durable roots. Remove what you can then treat or hoe emerging leaves weekly until the roots are exhausted. I am wrestling with the same issue on a former Japanese anemone spot. There is no easy or quick fix.

    If it's not spider webs, the webbing could due to spider mites or giant white fly. 70% neem oil sprayed weekly may achieve suppression of the pest.

    Sage, like lavender does not like "wet feet". If you have had lots of rain or been watering a lot, the plant may be suffering from root rot. I would cut it back by 1/3 and wait. (Don't cut back past all living leaves) If your soil is heavy clay, dig the plant up in early fall and work in some organic matter and coarse sand to improve drainage. Winter kill from rotting roots is a bigger hazard than cold temperatures. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/how-to-improve-clay-soil.htm

    If the roots are not damaged, your plant should recover.

    In most cases though you can trim the plant to about 6 inches in the fall or in the spring.

    Fortunately, much of what you are seeing is normal for this time of year. The white spots on the Russian sage stems are buds for next year. The brown arc on zonal geranium is usually present all the time and is a normal and common pattern. The phlox has a mild case of powdery mildew; no treatment is needed at this point in the season. Phlox is prone to PM. You can discourage its development by pruning out some stems at ground level. This improves air circulation and sunlight penetration. Try to water at soil level and prevent splashing as this may spread PM. Here is more info on phlox care: https://www.gardeningknowhow.com/ornamental/flowers/phlox/growing-garden-phlox.htm

    The best thing to do at this point is to just wait. They will want that old growth left on until Spring, when it will be suitable to cut it.

    Late spring is perfect for planting Russian sage. These plants love sun and heat, so your location sounds great. Make sure the plants have low-humidity conditions and relatively dry, well-drained soil. I don't see that it has any particular problems. Here's an article that may be helpful:
