Soil
This is probably the most important factor in their cultivation,as soil
type determines the length of time the plant remains wet.
Ideally the soil mixture should be compact to support the fine root
system. Mixtures should be slightly acidic and of the type that dries out
promptly. We have found sandy loam with a little acidic peat to be ideal.
Decomposed granite can be used and is also suitable for most other
succulents.
Water
Your watering schedule depends on the speed at which your soil dries out,
but use the following guidelines:
In the warm growing season drench the plant,
and leave to dry out completely. Add 2 to 3 days to this, before watering
again.
Plants should not remain wet for more than 5
to 7 successive days.
Stop watering altogether during the cold season,
allowing the old leaf pair to wither and the new pair to develop.
In this period lightly spray the heads(to simulate mist) once a fortnight.
Once the old leaf pair have shrivelled up entirely, recommence
your watering schedule.
Light and Heat
Lithops need (+/-) 4 to 5 hours of daily direct sun and dry air
conditions.
Beware of the following:
Magnification of sun from
windowpane
Too much humidity (allow ventilation)
Too little light (they grow tall and out of proportion)
A very important note: If your lithops have not been exposed
to direct sun, take care when moving them directly into the sun as they
easily suffer from sunburn. Many people have lost their lithops in this way.
It is best to introduce the plant slowly, leaving it in direct sun an
extra 10 minutes per day, until you have them at 4 to 5 hours/day.
