Notocactus erytracanthus PR85
This is an easy plant to cultivate.
It likes to be kept cool and need only a short rest in winter, it
can can tolerate light frost. Grow in full or light shade sun
but doesn't like full, hot blazing sun in the central
summer month. Water occasionally in winter so the roots do not
dry out completely and water regularly in summer. Some growers suggest
to use exclusively rain water. But be careful as it will rot easily if
the substrate is wet and cold. Tends to lose its roots in winter.
The root system of this plant is comparatively small and it is best to
grow it in a shallow pot using a neutral to slightly acidic compost with
plenty of extra grit. Give an occasional tonic of sequestrated iron.
Propagation: Usually by seeds as it
seldom produces offsets.
