Troubleshooting
Silver Hechtia problems — and how to fix them
Silver Hechtia (Hechtia argentea) 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.
Root rot from overwatering
The most common killer; always allow the soil to dry fully and ensure the pot has generous drainage holes.
Pale or washed-out colouration
Insufficient direct sun reduces the signature silver lustre; move to a sunnier position.
Crown rot
Water sitting in the central cup can rot the growing point; water at soil level rather than overhead.
Spine injuries
Sharp marginal teeth can lacerate skin and harm pets; handle with thick leather gloves and position carefully.
Scale insects
Can colonise the leaf axils; treat with isopropyl alcohol on a cotton swab or a systemic insecticide.
