Phragmipedium longifolium problems — and how to fix them
Phragmipedium longifolium (Phragmipedium longifolium) 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.
Salt sensitivity
Hard water and concentrated feed cause black leaf tips and root death. Use only pure water, keep fertiliser very dilute and flush the medium frequently.
Root and crown rot
Constantly wet roots with poor airflow invite rot. Maintain strong air movement, change standing water often and repot before the medium breaks down.
Leaf-tip dieback
The long leaves often show brown, dying tips from mineral build-up or fungal entry. Improve water quality, flush salts and trim cleanly with a sterilised tool.
Reluctant flowering
Too little light or an underfed, under-grown plant produces few or no spikes. Increase bright-indirect light and grow it strongly with steady dilute feeding.
