Troubleshooting
White Sage Brush problems — and how to fix them
White Sage Brush (Artemisia ludoviciana) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive spreading via rhizomes
The most significant management issue — plants spread assertively in good growing conditions. Install a physical root barrier at planting, or grow in containers sunk into the border. Divide and cut back annually to contain spread.
Rust (Puccinia spp.)
Orange pustules on undersides of leaves can appear in humid summers or on plants grown in overly moist soils. Improve drainage and airflow; remove and dispose of affected stems. Avoid overhead irrigation.
Flopping and lodging
In rich soil or partial shade, stems become tall, soft, and floppy. Cut plants back hard (by half) in late May or early June to encourage a bushier, more self-supporting habit and maintain the silvery foliage effect into autumn.
