How to care for Living Stones
sunlight
Living Stones grow in open, intensely sunny desert habitats, often with their tops level with the soil. Give them the brightest spot you have, with direct sun rather than a dim room.
Full sun
Place near a south- or west-facing window for several hours of direct light daily. An east window can work if it is unobstructed. In very hot climates, soften harsh afternoon sun with a sheer curtain, especially behind glass.
watering
These desert succulents need long dry spells. Their growth cycle varies by species and conditions, so use the leaf stage and fully dry mix rather than the calendar alone.
Late summer to autumn
During active growth and flowering, water about every 2-4 weeks, only when the potting mix is dry throughout and the plant is starting to wrinkle slightly. Soak the mix, then let excess drain away.
Winter to early spring leaf change
Keep dry for the whole leaf-changing period, often 2-3 months. Wait until the old leaves are fully papery and dry before watering again.
Late spring and summer rest
After leaf change, give water only if the plant is actively growing and has been dry for several weeks. In hot, low-growth weather, keep it dry for roughly 6-8 weeks; a severely shriveled plant may take a small drink.
Bright light, warmth, a small terracotta pot, and gritty soil shorten drying time. Lower light, cool weather, a large pot, or organic soil mean longer gaps between drinks.
humidity
Preferred humidity
Living Stones come from very dry, open habitats, so average dry household air suits them well. Good airflow matters more than added humidity.
Acceptable range
Below about 15%, hot forced air can make the bodies shrivel faster. Mild wrinkling is often normal during leaf change, so do not raise humidity or water just for that.
- If they look persistently deflated outside leaf-change season, first check light, soil dryness, and watering timing.
- In humid rooms, provide ventilation and let the potting mix dry fully to help prevent rot.
temperature
Active growth
Winter minimum
Native to hot, dry southern African habitats, Living Stones prefer warmth, bright light, and moving air. They can handle hotter conditions when kept dry and well ventilated, but protect them from cold, damp conditions and temperatures below 10°C (50°F).
nutrition
September - November
For most Lithops, feed once during active autumn growth, or at most every 6-8 weeks, with a liquid cactus fertilizer at about one-quarter strength. Choose one low in nitrogen and apply it only to already moist soil. Do not feed during summer rest, leaf replacement, or when the plant is not taking up water.
Nitrogen
Small amounts support new leaves, but too much can cause soft, stretched growth and make splitting more likely. A very dilute cactus fertilizer provides enough.
Potassium
Potassium supports sturdy tissues and flowering. A balanced cactus fertilizer supplies it without pushing rapid growth.
soil
Gritty, fast-draining soil
Living Stones need a mostly mineral, airy mix that dries quickly around their small roots. Use cactus soil cut with plenty of pumice, perlite, or coarse grit, rather than a rich potting mix that stays damp.
pH 6,0 - 7,5
This is slightly acidic to slightly alkaline, a range most cactus mixes naturally suit. Choose a mineral-based mix and avoid strongly acidic peat-heavy soils.
