About Aeonium Decorum

Aeonium decorum · also called green aeonium, chef's aeonium · houseplant

Aeonium decorum is a bushy, freely branching aeonium from El Hierro, forming many small rosettes of green leaves edged in copper-pink on slim woody stems. It makes a dense, shrubby specimen and colours up well in bright light. Like its relatives it grows in cool months, rests in summer heat and demands very sharp drainage to avoid rot.

Mature size: Roughly 30-60 cm (12-24 in) tall and wide; individual rosettes about 5-6 cm (2-2.5 in) across.

Watch for — Leggy, stretched stems: Insufficient light elongates stems and spaces out the rosettes. Move to brighter light and prune leggy stems back; the cuttings can be re-rooted to thicken the plant.

How to tell aeonium decorum needs repotting

Repotting on a calendar is less reliable than reading the plant. For aeonium decorum, 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.

How often to repot aeonium decorum

Every 2–3 years, into bone-dry mix. Aeonium Decorum's growth habit — bushy, much-branched aeonium that builds a rounded shrub of numerous small rosettes on woody stems. one of the more densely branching species, good for a full, mounded specimen. — sets the pace.

What size pot to step aeonium decorum up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Aeonium Decorum 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.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot aeonium decorum

Spring or summer, while aeonium decorum 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 aeonium decorum

Repot dry. Do not water aeonium decorum 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, free-draining cactus and succulent mix 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 aeonium decorum 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 aeonium decorum 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 aeonium decorum

Aeonium Decorum wants gritty, free-draining cactus and succulent mix. Use cactus mix amended with 30-50% pumice, perlite or coarse grit. The shallow, fibrous roots rot in dense, moisture-holding soil. A terracotta pot with drainage holes encourages even drying. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting aeonium decorum — frequently asked questions

How often should you repot aeonium decorum?

Every 2–3 years, into bone-dry mix for aeonium decorum. Repot aeonium decorum every 2–3 years into a snug pot of gritty, free-draining cactus and succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does aeonium decorum need?

When is the best time of year to repot aeonium decorum?

Should you water aeonium decorum after repotting?

No — not straight away. Repot aeonium decorum into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise aeonium decorum after repotting?

Not immediately. Wait about 3 weeks after repotting aeonium decorum. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
