Begonia 'Guy Savard' (guy savard begonia) care

Light

Begonia 'Guy Savard' 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, filtered light intensifies the silver and plum tones; an east-facing or sheer-curtained window suits it. Direct sun fades and scorches the leaf, while too little light dulls the metallic sheen. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water begonia 'guy savard' when the top 2 cm of mix is dry, roughly every 4-6 days. 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. Keep the mix lightly and evenly moist, watering from below or around the base to keep the crown dry. As a compact rex type it dislikes both drying out completely and sitting in water.

Soil and pot

Begonia 'Guy Savard' grows best in light, airy, free-draining houseplant mix. A peat-free or coir mix with added perlite and fine bark gives the aeration rex begonias need. Good drainage is essential to avoid rhizome and 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

Begonia 'Guy Savard' sits happiest at around 60-80% humidity and 18-24°C (64-75°F). As a miniature rex it loves high humidity and excels in a terrarium, cabinet or pebble-tray setup. Dry household air causes leaf-edge browning; avoid direct misting to deter mildew. 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 begonia 'guy savard' sparingly. Feed monthly through spring and summer with a balanced liquid fertiliser at quarter to half strength. Miniature rex begonias are easily over-fertilised, so err light and pause in 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 begonia 'guy savard' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Powdery mildew — Rex types mildew readily in still, humid air. Provide gentle airflow, keep foliage dry, and remove infected leaves.
• Leaf-edge browning — Low humidity crisps the delicate margins. Grow in a humid spot or enclosure rather than misting.
• Rhizome rot — Overwatering or a buried rhizome causes soft, blackened rot. Keep the rhizome on the surface and let the topsoil dry slightly.
• Faded colour — Insufficient light mutes the silver-and-purple pattern. Move to brighter indirect light.

Propagation

Propagate from leaf cuttings or rhizome sections in a warm, humid propagator. Pin a healthy leaf or wedge onto moist mix; plantlets form at the veins and can be potted on once established. 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

Begonia 'Guy Savard' is toxic to pets. The ASPCA lists Begonia as toxic to cats and dogs. The toxic principle is soluble calcium oxalates, most concentrated in the underground rhizome; ingestion can cause mouth irritation, intense burning, drooling and vomiting. Keep away from pets. 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.
