Above in a rainy day.
It rains on Dyckias!
There is no Dyckia in any desert.
It rains on Dyckia as it rains on any other plant here.
The difference lies on the way Dyckia deals with the water
...not in the way it copes without it.
It rains equally on the banana plant.
Dyckias live on rich organic drainable substrate and also in a very drainable terrain specially rocks.
Rocks are the first the get wet when it rains and the first to dry out when it ceases.
This position prevents the water to get stuck in the center of the crown.
