LIGHT- Cacti love bright and sunny locations, though you should be careful to avoid too much direct sun, as this can cause the plant to turn yellow or scar. Typically they need 4-6 hours of sun a day to thrive. Insufficient sun may exhibit signs as well, such as elongation.
WATER- During the spring, summer and fall months, indoor cacti will typically need a watering every 7-10 days. In the winter months, you can water them every 4-6 weeks.
PPRUNING- Cacti are generally low maintenance and don't require frequent pruning. The main reasons to prune are to take off damaged material, reinvigorate a plant that has grown too tall or leggy, and to take off pieces for propagation purposes. When pruning, make sure to protect yourself against the spines. The faster growing species can be repotted every 2-3 years while the slower growers can be repotted every 3-4 years.
TOXICITY - Generally non-toxic
