About Anthurium 'Black Love'

Anthurium andraeanum 'Black Love' · also called dark anthurium, black anthurium · tropical

Anthurium 'Black Love' is a flamingo-flower cultivar grown for its dramatic, deep maroon-black, lacquered spathes that contrast with glossy green heart-shaped leaves. An epiphytic aroid, it flowers almost year-round in warm, humid rooms with bright indirect light. Give it a chunky, airy mix and consistent moisture and it will keep pushing out its near-black blooms.

Mature size: Around 40-50 cm tall and 30-40 cm wide indoors.

Watch for — Root rot: A dense, water-retentive mix or overwatering rots the fleshy roots and yellows lower leaves. Repot into a chunky aroid mix and let the surface dry slightly between waterings.

How to tell anthurium 'black love' needs repotting

Repotting on a calendar is less reliable than reading the plant. For anthurium 'black love', 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 'black love' leaves are noticeably smaller than older ones despite good light.

How often to repot anthurium 'black love'

Every 12–18 months — sooner if roots show fast. Anthurium 'Black Love''s growth habit — evergreen, upright epiphytic aroid forming a clump of long-stalked, glossy heart-shaped leaves, with the dark spathe-and-spadix flowers held above the foliage. slow to moderate growth, producing aerial roots over time. — sets the pace. Anthurium 'Black Love' is a flamingo-flower cultivar grown for its dramatic, deep maroon-black, lacquered spathes that contrast with glossy green heart-shaped leaves.

What size pot to step anthurium 'black love' up to

Step up one pot size — about 2–3 cm (an inch) wider. Anthurium 'Black Love' 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 'black love'

Early spring, just as new growth restarts, is the ideal window for anthurium 'black love'. 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 'black love'

Time it for spring. Repot anthurium 'black love' 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 'black love' out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh coarse, airy 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 'black love' 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 'black love'

Anthurium 'Black Love' wants coarse, airy aroid mix. Use a very open mix of orchid bark, perlite, coco chips and some peat or coir to mimic its epiphytic roots. Excellent drainage and air around the roots are essential to prevent 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.

Repotting anthurium 'black love' — frequently asked questions

How often should you repot anthurium 'black love'?

Every 12–18 months — sooner if roots show fast for anthurium 'black love'. Repot anthurium 'black love' 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 coarse, airy aroid mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does anthurium 'black love' need?

When is the best time of year to repot anthurium 'black love'?

Can you put anthurium 'black love' straight into a much bigger pot?

No. Even a fast-growing anthurium 'black love' 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 'black love' after repotting?

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