About Oregon Stonecrop
Sedum oreganum · also called Oregon Stonecrop, Oregon Sedum · houseplant

An attractive alpine pot subject or container groundcover requiring minimal care.
Preferred mix: Gritty, well-drained sandy or cactus compost

Why oregon stonecrop needs this mix
Oregon Stonecrop is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Oregon Stonecrop is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for oregon stonecrop.
