Troubleshooting
Spatulate Dendrobium problems — and how to fix them
Spatulate Dendrobium (Dendrobium kingianum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Abundant keikis, few flowers
D. kingianum produces keikis very readily, especially if kept too warm, wet, or fed in winter. Give a cooler, drier, brighter winter rest to favour flower spikes over plantlets.
Soft, dark, rotting canes
Overwatering or a water-retentive mix rots this drainage-loving lithophyte. Use a coarse mix in a snug pot and let it dry between waterings, especially in winter.
No flowers
Usually too little light or insufficient winter cool-down. Provide bright light year-round and a distinctly cooler, drier winter to initiate the late-winter blooms.
Crowded, declining clump
Old congested clumps with dead backbulbs lose vigour. Divide and repot in fresh coarse mix every couple of years to rejuvenate growth.
Prevent spatulate dendrobium problems before they start
Most spatulate dendrobium issues are care-mismatch, not bad luck. Dial in the basics:
