The Desert Rose (Adenium obesum) is a popular houseplant from the Apocynaceae family, native to East Africa. It is rated Moderate to grow and typically reaches 30–90 cm indoors. Here is everything you need to keep it healthy — watering, light, humidity, feeding, propagation, and pet safety. It is a Moderate grower, putting on most of its growth in the warm, bright months of spring and summer.

💧Watering

Water your Desert Rose roughly every 7–14 days, letting the top few centimetres of soil dry out between waterings. Always empty the saucer so the roots never sit in water — overwatering is the most common way this plant is lost.

Not sure when to water? Push a finger 2–3 cm into the soil and water only when it feels dry at that depth — a cheap moisture meter or the weight of the pot works too. Water thoroughly until it runs from the drainage holes, then tip away anything left in the saucer. Soft, yellowing lower leaves usually mean too much water; crispy, curling leaves usually mean too little. Always ease off in the darker months, when the plant drinks far less.

☀️Light & placement

The Desert Rose thrives in full sun and needs as much direct light as you can give it indoors.

Give it your sunniest south-facing sill — the more direct light indoors, the better the colour and shape. Too little light makes it stretch and lose its compact form. Move plants outside for summer only after hardening them off gradually.

🌡️Temperature & humidity

Keep it between 15–35 °C and away from cold draughts and heating vents. It prefers Low humidity; if your air is dry, group it with other plants or use a humidifier.

🪴Soil & feeding

Plant it in gritty, fast-draining cactus/succulent mix. Feed with a light succulent feed once or twice in the growing season, and stop feeding in autumn and winter when growth slows.

🗓️Season-by-season care

Season	Watering	What to do
Spring (Mar–May)	Resume regular watering as growth restarts.	The main growing season begins — start feeding again, repot if it is pot-bound, and take cuttings now for the best success.
Summer (Jun–Aug)	This is the thirstiest season; check the soil more often.	Keep feeding on schedule, watch for pests in the warmth, and shield the leaves from scorching midday glass. Higher humidity is welcome.
Autumn (Sep–Nov)	Let the soil dry a little longer between waterings.	Taper off feeding as growth slows, and move the plant away from cold windows and doorways before the first chills.
Winter (Dec–Feb)	Water sparingly — overwatering now is the number-one killer.	Stop feeding, give it the brightest spot you have, and keep it away from radiators, heat vents, and cold draughts.

🪟Repotting

Repot roughly every 2 years, ideally in spring as growth picks up. Move up just one pot size (2–3 cm wider) with drainage holes — too big a pot holds water and invites root rot. Signs it is time: roots creeping from the drainage holes or circling the surface, water running straight through, or growth that has stalled. In the years you do not repot, scrape off and replace the top few centimetres of soil.

✂️How to propagate, step by step

Spring and early summer, during active growth, give the best success. Here is how to do it, step by step:

seed

Sow fresh seed onto the surface of moist, fine seed-starting mix.
Cover lightly only if the seed needs darkness; most need warmth of 20–25 °C.
Keep humid under a clear cover in bright, indirect light.
Germination ranges from days to months depending on the species — be patient.
Prick seedlings out into their own small pots once they have a few true leaves.

stem cuttings in soil

Cut a 10–15 cm stem just below a node and remove the lower leaves.
Dip the cut end in rooting hormone if you have it (optional).
Push it into moist, well-draining mix and firm the soil around it.
Cover loosely with a clear bag to hold humidity, and keep in bright, indirect light.
After a few weeks, a gentle tug that meets resistance means roots have formed — remove the bag and grow on.

🐛Pests & prevention

The usual indoor pests are spider mites (fine webbing, speckled leaves), mealybugs (white cotton-wool tufts), scale (small brown bumps), and fungus gnats (tiny flies from soggy soil). Inspect any new plant before it joins the others, wipe the leaves now and then, and let the topsoil dry to keep gnats away. At the first sign, isolate the plant, wipe or rinse off what you can, and treat with insecticidal soap or neem oil every week until it is clear.

🐾Is it safe for pets?

The Desert Rose is toxic to cats and dogs (cardiac glycosides (oleandrin-type)). Keep it out of reach of pets and children. If you think an animal has chewed it, contact your vet or a pet poison line. If a curious cat or dog chews it, it contains cardiac glycosides that can affect heart rhythm — ingestion is potentially serious and needs prompt veterinary attention. It is rarely life-threatening in small amounts, but rinse the animal’s mouth, take away any plant pieces, and call your vet if symptoms are severe or last more than a short while.

Toxicity information is a general guide based on ASPCA data. If your pet or child may have eaten any part of a plant, contact a vet or poison control right away.
