When and how much water
Water wax plant when the top 4 cm of soil feel dry. In summer that’s typically every 7 to 11 days. In winter, slow down to every 14 to 22 days. Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Light and placement
Wax plant needs bright light and a little gentle direct sun, such as morning sun. Strong midday sun can scorch the leaves. Place it close to an east- or west-facing window.
Feeding
Feed wax plant every 45 days while it’s actively growing. Use a balanced liquid houseplant fertilizer at half the strength on the label, and only on soil that’s already damp. Feeding dry roots can scorch them.
When growth pauses, skip the fertilizer and let it rest.
Temperature & humidity
Wax plant is comfortable between 18 and 27 °C. Below 10 °C the leaves start taking damage, so keep it clear of cold drafts and unheated rooms.
It does best at 50–70% humidity. It doesn’t need misting.
Common problems
Yellowing, drooping, and dry edges often point to watering or drainage. Compare the signs before changing the routine.

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 you see wrinkled waxy leaves, puckered leaves, or limp foliage instead, it’s likely thirsty. Water a little more often.
