donkey ears Care (Kalanchoe gastonis-bonnieri)

This succulent prefers bright light but needs some protection from harsh midday sun.

• Provide 4–6 hours of direct morning sun with bright, filtered light the rest of the day, especially for donkey ears in hot climates.
• In very hot regions, give only early sun and move to light shade after 11 a.m. to prevent leaf scorch and brown patches.
• If stems stretch or leaves lose color, increase light exposure gradually over 7–10 days to avoid sudden sunburn.

This species stores moisture in its leaves and needs infrequent, careful watering.

• Allow the top 3–5 cm of soil to dry completely before watering; the surface should feel dry and the pot feel lighter when lifted.
• Water deeply until excess drains out, then discard runoff; use fast-draining, gritty soil to prevent root rot in Kalanchoe gastonis-bonnieri.
• In winter or cool, low-light periods, extend drying time and watch for soft, yellowing leaves from overwatering or crisp, drooping leaves from underwatering.

Stable, warm conditions support strong growth for this succulent.

• Aim for 65–80°F (18–27°C) for active growth, with slightly cooler nights down to about 60°F (16°C).
• Protect from cold; growth slows below 55°F (13°C), and tissue damage occurs near 40°F (4°C), so avoid frost exposure entirely.
• Tolerates short hot spells up to 90–95°F (32–35°C) if shaded from intense midday sun and given slightly increased airflow.

This species handles typical indoor humidity well and rarely needs adjustment.

• Best growth occurs around 30–50% relative humidity, matching most heated and air-conditioned homes.
• Leaves stay healthy in quite dry air, but prolonged humidity above 60% can increase risk of fungal spotting.
• Humidity stress shows as soft, collapsing leaves or gray mold patches; improve airflow rather than misting to correct this.

Use a sharply draining, airy mix that mimics dry, rocky habitats.

• Combine 40% cactus mix with 30% coarse perlite or pumice and 30% mineral sand or fine gravel for a lean, open texture.
• Aim for slightly acidic to neutral pH, roughly 6.0–7.0, which supports nutrient uptake without encouraging rot.
• Increase aeration by using large-grain amendments (pumice, lava rock, coarse sand) and avoiding fine peat-heavy mixes that compact.
• For Kalanchoe gastonis-bonnieri, avoid water-retentive clay-based garden soil or dense compost layers that hold moisture around the roots.

This succulent is very suitable for container growing when given a stable, well-drained setup.

• Choose a wide, low container to balance the top-heavy leaf rosettes and reduce tipping risk in wind or on balconies.
• Select unglazed terracotta if extra evaporation is needed, or a thicker plastic pot if moisture retention is a problem outdoors.
• Ensure drainage holes stay clear and slightly elevate the pot on feet or bricks so excess water escapes quickly from the base.

This succulent benefits from light feeding during active growth but does not need heavy fertilization.

• Use a balanced liquid fertilizer (around 10-10-10 or 20-20-20) diluted to 25–50% strength for donkey ears in spring and summer.
• Feed every 4–6 weeks while growth is active, skipping any application if the soil is very dry.
• Reduce or stop fertilizing in fall and winter when growth slows or plants rest.
• Slow-release granules at low rate or a thin layer of compost can substitute for liquid feeds.

Thoughtful pruning keeps Kalanchoe gastonis-bonnieri compact, tidy, and flowering well.

• Best time is after flowering, removing spent flower stalks down to the base with clean, sharp scissors or pruners.
• Trim leggy, stretched stems back to a leaf node to encourage branching and a fuller shape.
• Cut away any dead, yellowing, or damaged leaves promptly to reduce disease risk.
• Disinfect tools before and after use to limit transmission of pests and pathogens.

This species prefers slightly tight roots and only needs repotting or transplanting occasionally.

• Check for roots circling the pot, emerging from drainage holes, or slowed growth as signs it needs more space.
• Plan repotting or transplanting in spring, about every 2–3 years, using a fast-draining succulent mix.
• Choose the next container only 2–5 cm wider to avoid excess wet soil around the roots.
• Gently loosen circling roots, keep the root ball mostly intact, water lightly afterward, and shade for a few days to reduce stress.

Kalanchoe gastonis-bonnieri is commonly propagated from leaf plantlets and stem cuttings.

• In spring or early summer, detach healthy plantlets that form along leaf edges and place them on barely moist, gritty mix.
• For stem cuttings, take 8–10 cm pieces, remove lower leaves, and let cut ends callus in dry air for 2–3 days.
• Set callused cuttings upright in well-drained substrate, keep warm (70–80°F), and water sparingly until roots form.
• Seeds can be sown on the surface of a sandy mix with bright, indirect light and evenly light moisture.

This succulent is frost sensitive and needs protection in regions with cold winters.

• Avoid exposure below 40°F; freezing temperatures can damage foliage and stems.
• In cold climates, grow in containers and move plants indoors before night temperatures drop near 45°F.
• Provide a bright, cool indoor spot, water sparingly, and keep soil on the dry side in winter.
• In mild climates, use a light mulch around the root zone to buffer brief cool spells, keeping mulch off the stems.
