Schlim's Phragmipedium problems — and how to fix them
Schlim's Phragmipedium (Phragmipedium schlimii) 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.
Leaf-tip dieback
The most common problem, caused by fluoride, chlorine, or mineral salts in tap water. Switch to rainwater or reverse-osmosis water and flush the medium regularly.
Root rot from hard water
Hard water deposits clog and kill roots over time. Exclusively use soft, pure water and repot annually into fresh medium.
Spider mites
Thin, soft leaves are susceptible in dry conditions. Maintain high humidity and treat with insecticidal soap at first sign of stippling.
Crown rot in warm conditions
Warm temperatures above 24°C combined with wet crowns can cause fatal rot. Keep cool and ensure water drains away from the leaf fan.
Failure to produce new spikes
Mature Phragmipediums can produce sequential spikes from the same flowering growth. If no new spikes appear, assess light levels and water purity.
