Cultivation: Matucana oreodoxa
grow slowly in their natural habitats, but in greenhouses or grafted
they grow quickly, with tissues that are less firm.
They benefit from a
good light but not severe sunlight.
Grow in rich, porous soil and let their soil dry out between waterings.
They need good drainage.
Repot in the spring when their roots become cramped. Generally, they
should be repotted every other year, in order to provide fresh soil.
However, this doesn't necessarily mean they'll need larger containers.
After repotting, do not water for a week or more.
