Wax plant care guideHoya carnosa
Waxy clusters of fragrant flowers. Ranked #44 of Europe's most-searched houseplants.
WateringWhen and how much water
Water Wax plant 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 plant is bright / direct light: needs several hours of direct sun. Turn the pot every week so it grows evenly. The ideal lux range is 10,000 - 50,000 lux. In practical terms, place it directly in front of a south or southwest window, or 30 cm from an east window.
TroubleshootingCommon problems
Most Wax plant problems trace back to watering — here's how to read the leaves.
Signs of overwatering
Watch for: Yellowing leaves · Mushy stems · Root rot · Dropping leaves. 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: Wrinkled waxy leaves · Puckered leaves · Limp foliage. Water a little more often and don't let the soil go bone-dry for long.

Field noteSomething worth knowing
A single peduncle (the woody flower stalk) can keep producing new flower clusters for more than a decade — never cut them off after blooming.

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