About Agave americana 'Mediopicta Alba'

Agave americana 'Mediopicta Alba' · also called white-striped century plant, medio-picta white agave · houseplant

A refined century plant cultivar with a broad creamy-white central stripe down each blue-green leaf, framed by toothed margins and a sharp tip. Slower and more compact than the plain species, it makes a luminous architectural specimen. Care is pure desert succulent: full sun, gritty fast-draining soil and infrequent water. Monocarpic, it offsets to continue after flowering.

Mature size: Usually 0.9-1.5 m tall and around 1.5-2 m wide; more compact and slower than the green species, smaller still in a pot.

How to tell agave americana 'mediopicta alba' needs repotting

Repotting on a calendar is less reliable than reading the plant. For agave americana 'mediopicta alba', 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 agave americana 'mediopicta alba' up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Agave americana 'Mediopicta Alba' 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 agave americana 'mediopicta alba'

Spring or summer, while agave americana 'mediopicta alba' 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 agave americana 'mediopicta alba'

Repot dry. Do not water agave americana 'mediopicta alba' 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 very free-draining cactus/succulent or gritty mineral 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 agave americana 'mediopicta alba' 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 agave americana 'mediopicta alba' 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 agave americana 'mediopicta alba'

Agave americana 'Mediopicta Alba' wants very free-draining cactus/succulent or gritty mineral mix. Cactus compost generously amended with pumice, grit or coarse sand, in a pot with a drainage hole. Avoid dense, water-retentive media. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
