When and how to water

Watering by month (northern hemisphere)
  • Summer · Jun–AugEvery 8 to 12 days
  • Winter · Dec–FebEvery 20 to 30 days, sometimes less often

Water your flaming Katy when the soil has dried out completely. In summer that’s typically every 8 to 12 days. In winter, slow down to every 20 to 30 days, sometimes less often. 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

Bright light, some sun

Flaming Katy 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 your flaming Katy every 30 days while it’s actively growing. Use a cactus and succulent fertilizer, which is lower in nitrogen, at half the strength on the label, and only on soil that’s already damp.

When growth pauses, skip the fertilizer and let it rest.

Temperature & humidity

Climate15–24 °C (59⁠–⁠75 °F)

Humidity30–60%

During leafy growth, aim for 15–24 °C (59⁠–⁠75 °F). For routine indoor care, keep it above about 10 °C (50 °F) and avoid cold drafts. This is a care guideline, not an exact damage threshold. Cooler overwintering depends on the species and its rest conditions.

It does best at 30–60% 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.

Toxic to pets?

Yes. Keep it out of reach.

Pet-safety information in the JungleBook uses ASPCA reference data where available. It is reference information, not veterinary advice. ASPCA lists the whole Kalanchoe genus, so this applies to every Kalanchoe species, including this one.

Is flaming Katy safe for cats and dogs?

This plant can cause serious poisoning. Contact a vet promptly, even if your pet seems well. Keep flaming Katy out of reach of pets, or pick a non-toxic alternative like Norfolk Island pine, pink jasmine, Madagascar jasmine, or hindu rope hoya.

Why is my flaming Katy turning yellow or drooping?

Yellowing, drooping and brown tips can have several causes. Check the potting mix before adding water and follow this plant’s watering and rest instructions. If the mix is still wet, do not add more water. Check drainage and roots, then light, humidity, water quality and pests. Faded color or webbing alone does not show that the roots need water.
