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

Sedum oreganum is a low, mat-forming succulent native to rocky coastal and mountain habitats of the Pacific Northwest.

An attractive alpine pot subject or container groundcover requiring minimal care.

Mature size: 5-15 cm tall; mat spreads 20-40 cm over several seasons

Watch for — Root rot from overwatering: The most common failure mode indoors. Use well-draining compost, pots with drainage holes, and allow the compost to partially dry before the next watering. Reduce watering substantially in winter.

How to tell oregon stonecrop needs repotting

Repotting on a calendar is less reliable than reading the plant. For oregon stonecrop, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

What size pot to step oregon stonecrop up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Oregon Stonecrop stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot oregon stonecrop

Spring or summer, while oregon stonecrop is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting oregon stonecrop

Repot dry. Do not water oregon stonecrop for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty gritty, well-drained sandy or cactus compost ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set oregon stonecrop at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep oregon stonecrop completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for oregon stonecrop

Oregon Stonecrop wants gritty, well-drained sandy or cactus compost. Requires fast-draining, low-nutrient compost or soil. A mix of standard cactus compost with additional perlite or fine grit suits container culture well. Soil that stays moist quickly leads to root rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
