Vanda 'Robert's Delight' (Robert's Delight Vanda) care

Light

Vanda 'Robert's Delight' needs sun on the leaves, not just bright ambient room light. One of the highest-light orchids — give several hours of bright sun, ideally morning sun with protection from scorching midday rays. A bright south or west window, sunroom, or grow light keeps it blooming; too little light gives lush leaves but no flowers. A south or west-facing windowsill in the northern hemisphere is the default; anywhere else, expect the plant to stretch and pale out within a season.

Watering

Water vanda 'robert's delight' daily in warm growth; every 2-3 days in cool or dormant spells. 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. Bare-rooted vandas in baskets need a thorough daily soak or drench so the aerial roots flush green and plump. In cooler, lower-light periods water less often. Roots should dry within a few hours; never leave them constantly sodden.

Soil and pot

Vanda 'Robert's Delight' grows best in bare-root in a slatted basket, or very coarse chunky media. Traditionally grown with no medium at all, hung bare-rooted in an open wooden or plastic basket so the roots have full air exposure. If potted, use only very coarse bark or charcoal chunks that drain and dry almost instantly. 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

Vanda 'Robert's Delight' sits happiest at around 60-80% humidity and 18-32°C (65-90°F). Needs high humidity to support its exposed aerial roots — 70% or more is ideal. In dry homes, mist roots, use a greenhouse case, or pair daily watering with strong airflow to prevent root desiccation and rot. 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 vanda 'robert's delight' sparingly. Heavy feeders in active growth — apply a balanced orchid fertiliser at quarter to half strength with most waterings during warm months (the classic weakly, weekly approach), flushing with plain water periodically. Reduce feeding in cooler, lower-light spells. 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 vanda 'robert's delight' in the Growli community. Each is annotated with the most common cause so you know where to start.

• No flowers despite healthy growth — Almost always too little light. Vandas need very high light — move to your sunniest spot or add strong grow lights to trigger blooming.
• Shriveled, gray aerial roots — Insufficient water or humidity. Soak roots until they turn green and plump, and raise ambient humidity for these exposed roots.
• Yellowing or dropping lower leaves — A few aging leaves are normal; rapid leaf loss signals root rot from staying wet too long or cold, damp conditions. Improve airflow and drying time.
• Limp leaves and stalled growth — Often cold stress below about 15°C. Keep it consistently warm; vandas resent chills and sudden temperature drops.

Propagation

Propagate by removing well-rooted basal offshoots (keikis) once they have several of their own roots, or by top-cutting an overly tall plant below a cluster of aerial roots and rebasketing the rooted top. Named hybrids come true only from such vegetative offsets. 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

Vanda 'Robert's Delight' is pet-safe. ASPCA-listed as non-toxic to cats and dogs — Vanda is part of the orchid family, which the ASPCA classes as non-toxic. A pet eating a large amount of leaf or root could get mild, temporary digestive upset, and any pesticide or fertiliser on the plant is a greater hazard than the orchid tissue itself. 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.
