Care at a glance
Light
Bright but filtered. Begonia 'Buxton's Crimson' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright, filtered light brings out the silver leaf spotting and keeps it flowering. An east or shaded south window is ideal; harsh direct sun bleaches and scorches the foliage, while low light makes stems stretch. 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 begonia 'buxton's crimson': when the top 2-3 cm of soil is dry, about every 5-7 days. 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. Water thoroughly, then let the surface dry slightly before the next drink; cane begonias resent constantly soggy roots. Reduce watering noticeably in winter when growth slows. Avoid splashing the leaves.
Soil and pot
Begonia 'Buxton's Crimson' grows best in light, free-draining, peat-free houseplant mix. A blend of multipurpose compost with perlite and a little bark gives the airy, moisture-retentive but never sodden root run cane begonias prefer. Use a pot with drainage holes. 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 'Buxton's Crimson' sits happiest at around 40-60% humidity and 16-24°C (60-75°F). Tolerates average household humidity better than rhizomatous or rex types. Moderate humidity keeps leaf edges from browning; group with other plants rather than misting, which invites leaf spot. If you keep the room above 16 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 'buxton's crimson' sparingly. Feed every 2-4 weeks in spring and summer with a balanced liquid houseplant feed, switching to a higher-potash feed to encourage flowering. Feed monthly or not at all 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 'buxton's crimson' in the Growli community. Each is annotated with the most common cause so you know where to start.
- Leggy, bare stems — Too little light or no pruning. Move to brighter indirect light and pinch growing tips to force branching lower down.
- Leaf drop — Often from cold draughts, dry air or letting the rootball dry out fully. Keep conditions stable and watering even.
- Powdery mildew — White coating in stagnant, humid air. Improve airflow and avoid wetting the foliage.
- Faded leaf silvering — Excess direct sun or very low light dulls the silver spots. Provide bright but filtered light to keep the markings crisp.
Propagation
Very easy from stem-tip cuttings in spring or summer, rooted in water or moist, gritty compost. Each cutting should include at least one node; pinch the rooted plant to encourage a bushy shape. 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 'Buxton's Crimson' is toxic to pets. ASPCA lists Begonia as toxic to cats, dogs and horses. The toxic principle is soluble calcium oxalates, most concentrated underground but present throughout. Chewing leaves or stems causes oral irritation, drooling and vomiting; grazing animals risk kidney damage. Keep out of reach of curious 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.
