Caring and collecting cactus plants can be very rewarding as the different breeds of cactuses can take on different forms. Unique cactuses have a mysterious appeal; and those that can bear flowers are particularly interesting. And as cactuses are not that demanding in water, this type of plant doesn’t require frequent watering. In fact, if you neglect watering a cactus, its chances for survival and recovery is quite high. The only negative thing about caring for cactus is that they can injure people when not handled properly. And having them around can be quite dangerous because of their thorns; so if you have children in your household, this is not such an ideal plant to have around.
