Unless you have some really great neighbors or relatives, there will come a time when you'll need to know how to care for your plants while you are gone. Life has become so busy and our interests so varied that most of us are away occasionally when our plants need attention. And sometimes, even though you are home, you just get busy and forget to water. There are several easy ways to help care for your plants when you can't be home or when you just don't have much time for routine maintenance. Start by evaluating your plant and learning what its specific needs are.
Plants vary greatly.
There are cacti and succulents that go weeks without anything but light. Other plants may need water almost daily. In addition to variation in the needs of specific plants, the care you need to provide can be influenced by the plant condition and the environment indoors. Slip your plant out of the pot and look at the root system. If the plant is very root bound, the soil won't be able to hold much moisture and it may need water more often than its counterpart that isn't root bound.
