Watering cacti isn’t exactly rocket science, but there are still a few things you should know. If you’ve ever come across a broken or cut cactus, you’ve noticed that they’re quite moist on the inside. That’s because the plant stores moisture as a way to adapt to very dry environmental conditions. This makes them potentially great house plants for people who don’t have much time for plant maintenance, but still would like to enjoy some green in their homes.
Different types of cacti will show different signs of distress when water is running too low. This is an indicator that it’s time to water. It’s important that you check the type of cactus you’ve got and follow watering instructions. For example, a barrel cactus only requires watering once every two to three months, while a bunny ear cactus should be watered lightly every three to four weeks. A Christmas cactus may need to be watered once a week.
During the summer months you may need to water a little more often as this tends to be growing season for many cacti. Fall and winter tend to be times during which cactus plants can get by on very little watering.
