Reviving a Neglected Janet Craig Dracaena: Pruning and Patience

Colleague's sentimental Janet Craig suffered during 2-week building closure. Owner cut tops, watered, fertilized, put tops in fertilized water—no roots in 2 weeks.

Correct Approach

• Top cuttings: ≤6 leaves, 4–6 inch bare stem. Root in plain water or soil-less mix. Roots take 1+ months; substantial roots in several months.
• Original plant: if roots healthy, new growth below cuts in ~1 month.
• Light: bright indirect, or 8 hrs/day fluorescent.
• Fertilizer is for healthy plants—not medicine for ailing ones.
