Troubleshooting Slow Recovery of Drosera adelae in Pacific Northwest

An Oregon grower (near Days Creek) has a year-old D. adelae struggling despite 5-6 hours east-window sun, consistent moisture, 70-75°F. A younger plant from the same source thrives. Older plant shows abnormal leaf growth. Asks how to help the older plant.

Lighting Deficiency

East windows in PNW often have persistent morning fog, reducing effective light. 5-6 hours is low even for this "low-light" carnivore. Ideal: bright filtered/dappled sun all day, or several hours direct morning sun + bright indirect rest of day. Supplement with artificial light or move to south window. Fall/winter will worsen east-window light.

Potential Pest Issue

Abnormal leaves and lack of new shoots suggest root or foliar pests. Common: aphids, thrips (cause leaf deformation). Systemic insecticide treats both soil and leaf pests. Watch insecticide video: YouTube link

Water Quality

Confirm using distilled/RO water, not high-mineral well water.

Follow-Up

After changes, expect improvement in 1 month. If not, provide detailed growing conditions for further diagnosis.
