How to Care for the Plant

Water
In the summer months, water only when the soil has dried out completely. Always err on the side of underwatering. They are built to withstand drought, and overwatering is one of the quickest ways to kill them. Water less in the winter months and only when there is a stretch of sunshine in the forecast.
Fertilizer
The Tephrocactus do not require fertilizer though it can be added to give container grown plants a boost or to supplement poor soil. Apply a water-soluble, balanced fertilizer monthly, diluted at half strength.
Sunlight
These cacti prefer lots of sun, at least 5 to 8 hours of direct sun daily. Indoors a south facing window is ideal. Outdoors place them where they will receive plenty of sun exposure, but protect them from intense, peak afternoon sun.

Soil
The soil must have good drainage, and it must be porous. Combine cactus mix with sand, pearlite, or another mineral that helps with the porosity. In case you could not find the cactus mix, you may opt for using potting mix. Keep in mind that the mineral must be present in a greater quantity than the cactus mix, for example, 25% cactus mix, and 75% mineral.
Temperature
this plant can go in hot temperatures as well as frosting times. Just be sure it is not receiving water, and everything will be right.
