First thorough watering for these newcomers. Weather has been warm but not too sunny, so I think they have adapted to local climate meanwhile. More than one-year-old Lithops are watered once a month with a flush of water, able to wash away salt deposits. For this purpose the pot gets water over a period of a few hours, until you can tell the soil is wet everywhere. Then the pot is gently flooded until water pours out freely. Inbetween the waterings all my Lithops get sprinkled every other day, like heavy dew, preferably in the early evening. Watering is never done during a hot weather spell.
A few days later: Two of them are growing – you can tell they emerge from the soil. The third – the big one – is collapsing. Tissue collaps in Lithops is fulminant – nothing you can do. Sad loss – this little mennellii was really cute.
