About Anthurium x 'Ace of Spades'

Anthurium x 'Ace of Spades' · also called Ace of Spades anthurium, dark velvet anthurium · tropical

'Ace of Spades' is a collector velvet-leaf anthurium grown for its broad, near-black, matte heart-shaped leaves with contrasting pale veins, derived from the Anthurium crystallinum/clarinervium group. This terrestrial-to-epiphytic aroid is a foliage plant, not a bloomer; it rewards bright indirect light, very high humidity, warmth and an open, fast-draining mix.

Mature size: Around 45-70 cm tall and wide indoors, with individual leaves to 30 cm or more.

Watch for — Root rot: Caused by dense or soggy mix; replant in a chunky bark-and-perlite aroid blend and let the surface dry between waterings.

How to tell anthurium x 'ace of spades' needs repotting

Repotting on a calendar is less reliable than reading the plant. For anthurium x 'ace of spades', watch for these signs:

Roots poking out of the drainage holes or coiling visibly around the inside of the pot.
You are watering far more often than you used to because the rootball dries out within a day or two.
Water runs straight through and out the bottom without soaking in.
Top growth has slowed or new anthurium x 'ace of spades' leaves are noticeably smaller than older ones despite good light.

How often to repot anthurium x 'ace of spades'

Every 12–18 months — sooner if roots show fast. Anthurium x 'Ace of Spades''s growth habit — evergreen foliage aroid that grows upright from a central crown, producing large velvety heart-shaped leaves; mostly terrestrial in cultivation but with semi-epiphytic, climbing tendencies on a short caudex. — sets the pace.

What size pot to step anthurium x 'ace of spades' up to

Step up one pot size — about 2–3 cm (an inch) wider. Anthurium x 'Ace of Spades' grows fast, so it will fill that space within a season, but jumping several sizes at once still backfires: the unused soil stays soggy and rots even a vigorous root system. One size at a time, every year or so, is the rhythm.

The best time of year to repot anthurium x 'ace of spades'

Early spring, just as new growth restarts, is the ideal window for anthurium x 'ace of spades'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting anthurium x 'ace of spades'

Time it for spring. Repot anthurium x 'ace of spades' in early spring as growth restarts so it re-roots quickly into the fresh soil.
Choose one size up. Pick a pot about 2–3 cm wider with drainage holes. One step only — a much bigger pot stays soggy and rots roots.
Ease the plant out. Water lightly the day before, then tip anthurium x 'ace of spades' out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh chunky aroid mix in the new pot, set the plant so its soil line is unchanged, and backfill, firming lightly.
Water and pause feeding. Water once to settle the soil. Hold off fertiliser for about a month — fresh mix already has nutrients and feeding now burns new roots.

Aftercare

Water anthurium x 'ace of spades' once to settle the soil, then let the surface dry before watering again — fresh mix around the roots stays wetter than the old compacted ball, so the commonest post-repot mistake is overwatering. Keep it out of direct sun for a week or two while roots re-establish. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for anthurium x 'ace of spades'

Anthurium x 'Ace of Spades' wants chunky aroid mix. Use a very open blend of orchid bark, perlite, charcoal and sphagnum so the coarse roots get constant airflow. Dense, water-retentive potting soil quickly causes root rot in velvet anthuriums. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting anthurium x 'ace of spades' — frequently asked questions

How often should you repot anthurium x 'ace of spades'?

Every 12–18 months — sooner if roots show fast for anthurium x 'ace of spades'. Repot anthurium x 'ace of spades' roughly every 12–18 months, in early spring as growth restarts. It grows fast and circles its pot quickly, so step up one size (about 2–3 cm wider) into fresh chunky aroid mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does anthurium x 'ace of spades' need?

When is the best time of year to repot anthurium x 'ace of spades'?

Can you put anthurium x 'ace of spades' straight into a much bigger pot?

No. Even a fast-growing anthurium x 'ace of spades' should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise anthurium x 'ace of spades' after repotting?

Not immediately. Wait about 4 weeks after repotting anthurium x 'ace of spades'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
