Succulents of any variety I plant directly into the soil and leave for them to fend for themselves, they really don't need water, most do love the direct sun during some part of the day.

This photo was 2014 still establishing the plant in a pot before planting into the garden.

Impala lily is under awning of the roof, only driving rain enters the area or it gets some water from the air conditioning unit during the heat of Summer.
