Wax begonia care guideBegonia x semperflorens-cultorum
Common flowering begonia. Ranked #51 of Europe's most-searched houseplants.
WateringWhen and how much water
Water Wax begonia when the top 2 cm of soil feel dry. In summer that's typically every 5 to 7 days; in winter slow down to every 10 to 14 days. Use room-temperature water and let any excess drain — never leave the pot sitting in standing water.
The real schedule depends on three things the calendar can't see: the actual light at the plant, the pot's size and material (terracotta dries faster than glazed ceramic), and your local humidity. Botanicaly's app retunes the schedule from those signals on every reminder.
LightHow bright a spot it needs
Wax begonia is medium / indirect light: thrives in bright, indirect light. Direct midday sun can scorch the leaves. The ideal lux range is 2,000 - 10,000 lux. In practical terms, place it 1-2 metres back from an east or west window, or behind a sheer curtain on a south window.
TroubleshootingCommon problems
Most Wax begonia problems trace back to watering — here's how to read the leaves.
Signs of overwatering
Watch for: Yellowing leaves · Mushy stems · Crown rot · Soft stem base. Let the soil dry further between waterings and make sure the pot drains freely — soggy roots are the usual cause.
Signs of underwatering
Watch for: Wilting leaves · Crispy leaf edges · Drooping foliage · Flower drop. Water a little more often and don't let the soil go bone-dry for long.
Pet safetyToxic to pets
Toxic to pets. The plant contains soluble calcium oxalates, which causes oral irritation, drooling, and vomiting if chewed. Keep Wax begonia out of reach of pets, or pick a non-toxic alternative like African violet, Christmas cactus, or Areca palm.

Why are my Wax begonia's leaves turning yellow or drooping?
On a Wax begonia, yellowing and soft growth usually mean overwatering — watch for yellowing leaves, mushy stems, or crown rot. Let the soil dry further between waterings and check drainage. If the leaves are wilting leaves, crispy leaf edges, or drooping foliage instead, it's likely thirsty — water a little more often. Botanicaly's Plant Doctor can diagnose it from a photo.
