Dividing Drosera regia (King Sundew): Timing, Technique, and Soil Mix

Drosera regia forms multi-crowned clumps over time. Division is best done in cool weather (winter) to minimize heat stress—this species dislikes warmth. Unpot gently; if each crown has long, independent roots, separate them. If roots are shared or short, wait until they elongate.

Your proposed mix (2 sand : 1 peat) is excellent. D. regia tolerates Osmocote slow-release fertilizer (3–4 pellets every 3–4 months), unlike most carnivorous plants.

If the clump isn't overcrowded, division isn't necessary—these grow naturally as clumps in the wild. Divide only to propagate or manage size.

Tip: Root cuttings (shown on our Volume 2 DVD) are another reliable propagation method for this species.
