About Bleeding Heart Vine

Clerodendrum thomsoniae · also called Bleeding Glory Bower, Bag Flower · tropical

Clerodendrum thomsoniae is an elegant tropical twining vine from West Africa producing striking bicoloured flowers: pure white heart-shaped calyx lobes contrasting with vivid crimson petals. It flowers profusely in warm, bright conditions and is an excellent indoor climber. The ASPCA does not list it as toxic, but the Clerodendrum genus warrants caution.

Mature size: 2-4 m indoors with support; larger in frost-free garden conditions

Watch for — Leaf yellowing: Often caused by overwatering, poor drainage, or low temperatures; check roots for rot and reduce watering.

How to tell bleeding heart vine needs repotting

Repotting on a calendar is less reliable than reading the plant. For bleeding heart vine, 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 bleeding heart vine leaves are noticeably smaller than older ones despite good light.

How often to repot bleeding heart vine

Every 12–18 months — sooner if roots show fast. Bleeding Heart Vine's growth habit — twining tropical vine — sets the pace. Clerodendrum thomsoniae is an elegant tropical twining vine from West Africa producing striking bicoloured flowers: pure white heart-shaped calyx lobes contrasting with vivid crimson petals. It flowers profusely in warm, bright conditions and is an excellent indoor climber. The ASPCA does not list it as toxic, but the Clerodendrum genus warrants caution.

What size pot to step bleeding heart vine up to

Step up one pot size — about 2–3 cm (an inch) wider. Bleeding Heart Vine 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 bleeding heart vine

Early spring, just as new growth restarts, is the ideal window for bleeding heart vine. 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 bleeding heart vine

Time it for spring. Repot bleeding heart vine 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 bleeding heart vine out and gently loosen any roots circling the bottom of the rootball.
Repot at the same depth. Put a layer of fresh rich, well-draining potting 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 bleeding heart vine 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 bleeding heart vine

Bleeding Heart Vine wants rich, well-draining potting mix. Use a fertile potting compost with added perlite (20–30%) to ensure both moisture retention and free drainage. A slightly acidic pH of 5.5–6.5 suits the plant well. Repot every two to three years in fresh compost. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting bleeding heart vine — frequently asked questions

How often should you repot bleeding heart vine?

Every 12–18 months — sooner if roots show fast for bleeding heart vine. Repot bleeding heart vine 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 rich, well-draining potting mix. Don't jump several sizes — that soggy excess soil is what rots vigorous roots.

What size pot does bleeding heart vine need?

When is the best time of year to repot bleeding heart vine?

Can you put bleeding heart vine straight into a much bigger pot?

No. Even a fast-growing bleeding heart vine 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 bleeding heart vine after repotting?

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