I just received an indoor cactus. What is the best way to take care of it?
Find a cool sunny location for your cactus in the winter. A south facing window is the best. Supplement the low light of winter with artificial light for better results. Water thoroughly but only when the top few inches of soil are dry. As the days lengthen and temperatures warm you will need to water more often. Some gardeners move their cacti and succulents outdoors for the summer. If you decide to do so, gradually introduce the plants to the sunnier conditions outside. You will need to water cacti growing outdoors frequently. Check them daily. Look for insects and adjust your watering schedule when moving the plants back inside for winter. Many gardeners find it less stressful to keep the plants indoors year round. The cacti will grow fine either way.
