Bleeding heart vine (Glory bower) care

Light

Bright but filtered. Bleeding heart vine burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright, indirect light suits it best indoors; an east window or a few feet back from a south or west window is ideal. It tolerates a little gentle morning sun, but harsh midday rays scorch the leaves. Too little light and it sulks and refuses to flower. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering bleeding heart vine: when the top 2-3 cm (1 in) of soil dries. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep the soil consistently moist (never soggy) through spring and summer, watering thoroughly once the top inch dries. The roots resent standing water. During the cool winter rest, water just enough to stop the mix drying out completely, then resume regular watering as growth restarts.

Soil and pot

Bleeding heart vine grows best in rich, well-draining potting mix. Use a fertile, peat-free or coir-based mix lightened with perlite or bark for sharp drainage. A slightly acidic to neutral pH is fine. Always pot into a container with drainage holes; sitting in water is the fastest route to root rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Bleeding heart vine sits happiest at around 50-60%+ humidity and 18-29 C (cool winter rest ~13-16 C) (65-85 F (cool winter rest ~55-60 F)). Loves high humidity. Below about 50% the foliage can brown at the edges and buds may drop. Group with other plants, stand the pot on a pebble-and-water tray, or run a humidifier. It dislikes dry, draughty air from radiators and vents. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed bleeding heart vine sparingly. Feed every 2-4 weeks through the growing season (spring to early autumn) with a balanced or bloom-boosting liquid fertiliser diluted to half strength. Stop feeding entirely during the winter rest period, resuming only when new growth appears in spring. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on bleeding heart vine in the Growli community. Each is annotated with the most common cause so you know where to start.

• No flowers — Almost always caused by skipping the cool winter rest. A spell at roughly 13-16 C with reduced watering and no feed is what triggers flower-bud formation for the next season. Too little light also suppresses blooming.
• Yellowing leaves and leaf drop — Some leaf drop in autumn/winter is normal as the plant rests. Excessive yellowing usually means overwatering, poor drainage or too little light. Check that the pot drains freely and let the surface dry between waterings.
• Bud and leaf-tip browning — A sign of air that is too dry. Raise humidity above 50% and keep the plant away from radiators, heat vents and cold draughts, all of which stress the foliage and cause buds to drop.
• Spider mites — Thrive in warm, dry air and show as fine webbing and stippled, fading leaves. Raise humidity, rinse the foliage, and treat with insecticidal soap or neem oil, repeating to break the cycle.
• Mealybugs — White, cottony clusters tuck into leaf joints and stem nodes, sapping vigour. Dab them off with an alcohol-dipped cotton bud and follow up with insecticidal soap or neem until clear.
• Root rot — Mushy stems, collapse and a sour smell point to roots sitting in water. Use a free-draining mix and a pot with drainage holes, and ease off watering during the winter rest.

Propagation

Easiest from stem-tip cuttings about 10-15 cm (4-6 in) long, taken in spring or late summer just below a leaf node. Root in moist mix or water with warmth and humidity (a covered tray or propagator helps); roots typically form in one to two weeks. Seed is possible but slower and less reliable. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Bleeding heart vine is mildly toxic to pets. Clerodendrum is NOT listed in the ASPCA's toxic or non-toxic plant database, so no clearance exists; the Pet Poison Helpline reports the genus as mildly toxic, causing gastrointestinal upset if eaten and contact dermatitis in cats, dogs, horses and birds. Treat as mildly toxic and keep away from pets. Note: this is NOT the toxic true bleeding heart (Dicentra), a completely different, unrelated plant. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
