Herre's Living Stone problems — and how to fix them
Herre's Living Stone (Lithops herrei) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rot during dormancy
Watering in summer is the primary cause of plant death. Observe the strict dry summer rest regardless of how shrivelled the plant appears.
Sunscorch after relocation
Even though this species is sun-tolerant, plants moved suddenly from lower light can scorch. Acclimatise over 1-2 weeks.
Failure to flower
Usually insufficient light or an incorrect watering schedule. Ensure a full dry summer rest and maximum light in autumn to trigger budding.
Mealybugs
Common in the crevice between lobe pairs and at soil level. Treat with isopropyl alcohol or a systemic insecticide drench for soil-level infestations.
Split lobes (abnormal)
A sign of overwatering during the growing season, causing the bodies to expand faster than the skin can stretch. Reduce water frequency.
