Hoya 'Sunrise' (Sunrise Hoya) care

Light

In the wild hoya 'sunrise' grows on the bright edge of a forest canopy, not in the canopy and not in the open. Indoors, that translates to within a metre of an unobstructed window, sheer curtain optional. Very bright indirect light, with a few hours of gentle direct sun, is what triggers the famous red-bronze leaf colour; in shade it stays plain green. An east window or right beside filtered south/west glass is ideal. Build up to brighter exposure gradually to avoid scorch. The fastest test: a hand held at the leaf casts a soft-edged shadow at noon — sharp shadow means too much sun, no shadow means too little light.

Watering

Aim for when the top 2-3 cm of mix is dry, roughly every 7-12 days for hoya 'sunrise', but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water well and let it drain, then allow the mix to dry down before watering again. The thinner leaves of this hybrid dry a touch faster than thick-leaved hoyas, so monitor more often, but still avoid constant moisture. Ease off in winter to prevent rot.

Soil and pot

Hoya 'Sunrise' grows best in free-draining chunky epiphytic mix. Use an airy blend of orchid bark, perlite, and a little peat-free potting mix or coir for moisture retention without sogginess. Good drainage is non-negotiable. A pinch of charcoal keeps the medium sweet between repottings. 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

Hoya 'Sunrise' sits happiest at around 50-70% humidity and 18-28°C (65-82°F). Appreciates moderate to higher humidity, reflecting its lacunosa parentage; 50% and above keeps the foliage looking its best. It copes with average household air but grows lusher with a humidifier or a pebble tray. Avoid dry drafts. 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 hoya 'sunrise' sparingly. Feed every 3-4 weeks through spring and summer with a balanced houseplant fertiliser at half strength. A bloom-boosting feed when buds appear supports the fragrant umbels. Stop feeding in autumn and winter while growth is dormant. 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 hoya 'sunrise' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Stays plain green — Without enough light the prized red-bronze 'sunrise' colouring never develops. Increase bright indirect light and add a little gentle direct sun, raising exposure gradually so the leaves stress to colour without burning.
• Crispy leaf edges — Browning tips and edges point to too-dry air or underwatering combined with strong sun. Raise humidity toward 50-60% and keep watering consistent during the growing season.
• Root rot — Yellowing, soft stems and collapse follow overwatering in a dense mix. Use a chunky, fast-draining medium, let it dry between waterings, and ensure the pot drains freely.
• Mealybugs — Cottony white pests hide in leaf joints and new growth. Wipe away with alcohol on a swab and repeat treatments; inspect the compact growth regularly.

Propagation

Propagate from stem cuttings with one to two nodes, rooting in water, sphagnum, or a chunky mix in warm, bright indirect conditions. Keep a node covered and humidity up for faster rooting. Take cuttings in spring or summer; the hybrid comes true only from cuttings. 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

Hoya 'Sunrise' is pet-safe. ASPCA-listed as non-toxic to cats and dogs. The Hoya genus (wax plant) appears on the ASPCA non-toxic list, so this hybrid is considered pet-safe; as with any houseplant, eating a large quantity may cause mild stomach upset, and keep recently fertilised plants out of reach. 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.
