When and how much water
Water Hibiscus when the top 3 cm of soil feel dry. In summer that’s typically every 2 to 4 days. In winter, slow down to every 6 to 8 days. Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Adjust the timing for the light at the plant, the pot’s size and material, and the humidity indoors. Terracotta dries faster than glazed ceramic.
Light and placement
Hibiscus needs several hours of direct sun. Turn the pot every week so it grows evenly. Place it directly in front of a south- or southwest-facing window.
Feeding
Feed Hibiscus every 14 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
Hibiscus 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. Misting every 2 days helps in dry rooms.
Common problems
Yellowing, drooping, and dry edges often point to watering or drainage. Compare the signs before changing the routine.

Common questions
How often should I water a Hibiscus?
Water your Hibiscus (Hibiscus rosa-sinensis) when the top 3 cm of soil feel dry. In summer, that’s typically every 2 to 4 days. In winter, slow down to every 6 to 8 days.
How much light does a Hibiscus need?
Hibiscus needs several hours of direct sun. Turn the pot every week so it grows evenly. Place it directly in front of a south- or southwest-facing window.
Is Hibiscus safe for cats and dogs?
Hibiscus is not listed in the ASPCA’s toxic and non-toxic plant database, so we cannot confirm it is safe for cats and dogs. Keep it out of reach of pets, and call your vet if your pet chews it.
Why are my Hibiscus’s leaves turning yellow or drooping?
On a Hibiscus, yellowing and soft growth usually mean overwatering: watch for yellowing leaves, leaf drop, or mushy stem base. Let the soil dry further between waterings and check drainage. If you see wilting leaves, crispy leaf edges, or flower bud drop instead, it’s likely thirsty. Water a little more often.
