Late-Summer Drosera filiformis/tracyi Dieback: Normal Seasonal Decline

A Vancouver, WA grower’s D. filiformis hybrids and D. tracyi showed outer leaf dieback despite healthy centers and new growth. Plants outdoors in full sun, constant distilled water, daily top-watering in heat.

Jeff Dallas said this is normal late-summer behavior. These species grow vigorously early/mid summer, slow after blooming, and go dormant by September. D. tracyi gets floppy; old leaves die. At dormancy, a tight hibernaculum forms in the crown until spring.
