Drosera multifida 'Extrema' Winter Dieback: Dormancy or Repotting Time?

Diagnosing Seasonal Decline in Fork-Leaf Sundew

Washington grower's year-old D. multifida 'Extrema' (T5s, 12 hrs, water tray, peat/sand) had leaves blacken, new growth blacken, mold on soil surface. Looks dormant. Asked: fungus or winter dormancy?

Expert Assessment (Jeff Dallas)

Soil appearance suggests repotting time. Plant looks dormant. Many D. binata have dormancy. 'Extrema' from warmer Australia—may have summer dormancy instead. Nursery multifida extremas don't go dormant.

Recommendations

Repot now.
Try lowering temperature to trigger active growth.
Most D. binata dormancy ~2 months.
