Hoya Loyceandrewsiana (Loyce Andrews Hoya) care

Light

Hoya Loyceandrewsiana is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright, indirect light fuels its large leaves and flowering and deepens the red flush on new growth. Filtered sun is fine; avoid intense direct sun that scorches the broad leaves. Too little light stalls this big grower. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water hoya loyceandrewsiana when the top 3-5 cm of mix is dry, roughly every 7-14 days in growth. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water thoroughly, then let the surface dry before the next drink. The thick leaves store water, so lean toward underwatering; soggy roots rot quickly. Reduce watering markedly in winter.

Soil and pot

Hoya Loyceandrewsiana grows best in coarse, very free-draining epiphytic mix. Use a high proportion of orchid bark and perlite with some coco coir so the substantial roots get air. Avoid heavy potting soil. Generous drainage is essential for this large species. 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 Loyceandrewsiana sits happiest at around 60-80% humidity and 18-29°C (65-85°F). A Philippine forest epiphyte that grows best in higher humidity, producing larger, healthier leaves. It tolerates average air but rewards a humidifier or pebble tray, especially in heated rooms. 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 loyceandrewsiana sparingly. Feed every 3-4 weeks in spring and summer with a balanced liquid fertiliser at half strength; a bloom formula supports its large flower umbels on this heavy grower. Stop feeding in autumn and winter. 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 loyceandrewsiana in the Growli community. Each is annotated with the most common cause so you know where to start.

• Overwatering and root rot — Large succulent leaves mean low water needs; wet, dense mix rots the thick roots fast. Let the surface dry and use a very airy substrate.
• Slow establishment and blooming — Young plants vine before flowering. Provide bright light, high humidity and a support, and keep it slightly pot-bound to encourage blooms.
• Sunburn and faded new growth — Strong direct sun scorches the broad leaves and washes out the red flush. Diffuse intense light with a sheer curtain.
• Mealybugs — Hide on the undersides of the big leaves and in stem joints. Inspect regularly and treat with isopropyl alcohol or insecticidal soap.

Propagation

Propagate from stem cuttings bearing at least one node; root in sphagnum moss or a perlite mix with warmth and high humidity. Large-leaved Hoyas root more slowly, so allow 4-8 weeks. 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 Loyceandrewsiana is pet-safe. ASPCA-listed as non-toxic to cats and dogs; the genus Hoya is on the ASPCA non-toxic plant list (wax plant). Considered pet-safe, with only mild, temporary GI upset possible if a pet chews a large quantity of foliage. 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.
