In cultivation, Cactus plants generally will not succeed in moist climates. They usually require a sunny position in a well-drained, circumneutral soil and to be kept more or less dry in the dormant season[
Fruit - raw[
]. The fruit is covered with a soft white wool[
].. The fruits are juicy at first but become dry, they are around 25mm long[
The flesh of the young plants is said to be employed for making a sweetmeat, like that prepared from Ferocactus[
The pulp of the stem of Echinocactus species can be used as an emergency supply of water for drinking. Native peoples had various methods of obtaining the water, one of the easiest is to simply squeeze the moisture out of the pulp and into a container by hand. The resulting liquid is at least refreshing, though unpleasant and slimy to the taste[
