Troubleshooting
Lance-leaf Stelis problems — and how to fix them
Lance-leaf Stelis (Stelis lanceola) 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.
Browning leaf tips
Caused by low humidity, mineral build-up from tap water, or fluoride sensitivity. Switch to rainwater or reverse-osmosis water, increase humidity, and flush the medium regularly to reduce salt concentration.
Sparse flowering
Without a mild cool and slightly drier winter rest (10–13°C nights for 6–8 weeks), lance-leaf Stelis may produce vegetative growth but fail to initiate blooms. Simulate a seasonal shift to trigger flowering.
Aphids on new racemes
Soft-bodied aphids are attracted to developing flower spikes, causing distorted blooms. Treat with insecticidal soap spray or a dilute neem oil solution, targeting the growing tips. Repeat weekly until clear.
