Place your ZZ plant in a moderate to bright location avoiding direct afternoon sun in summer. They are also quite tolerant of low levels of light.
The Zamioculcas plant is much like a cactus when it comes to watering. They are drought-tolerant plants so it is best to let the top 2-3 inches of soil to dry out in between waterings from spring to autumn. Water even more sparingly in the winter. Overwatering will cause leaves to yellow and the tubes will rot.
Average room temperature between 13-26°C is ideal. Warmer temperatures in the upper range, however, will give an increase in growth output.
It is not necessary to fertilize ZZ plants, but if you wanted to, use a houseplant fertilizer diluted to half strength and fertilize one to two times a year during spring and summer.
Use a well-draining potting soil. Re-pot if needed in spring, move it to a warm room with low lighting and withhold water for about a week to allow it to recover from repotting.
