Troubleshooting
Stardust Dendrobium problems — and how to fix them
Stardust Dendrobium (Dendrobium 'Stardust') 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.
No reblooming after first flowers
This hybrid requires a mild cool dry rest (reduce watering, lower temperatures to 13–16°C / 55–61°F for 4–6 weeks in winter) to set flower buds for the following season. Maintaining warm, moist conditions year-round prevents reflowering.
Yellow lower leaves
Oldest pseudobulb leaves yellowing and dropping naturally is normal. Widespread yellowing during growth indicates overwatering, poor drainage, or root rot. Check the root system and reduce watering frequency.
Mealybugs at pseudobulb bases
Mealybugs can colonise the junction between pseudobulbs and sheaths. Treat with isopropyl alcohol on a cotton swab and follow with neem oil or insecticidal soap applied every 7–10 days for 3–4 treatments.
