When a plant outgrows its plant container, it is "pot-bound" or "root-bound." It no longer grows, and its roots begin to come up out of the dirt, as well as emerge from the drainage holes on the bottom of the plant container. The roots have become cramped and packed tightly into the container, like the roots of the bush lily in the picture on the right.
In the Pacific Northwest of the United States, there is a problem with invasive English ivy taking over local wildlife (it is native to Europe and western Asia). It's gotten so bad that the plant is actually banned in Oregon. In order to combat the ivy plant that has taken over local parks, volunteers rip it out. If you have a problem with ivy in your area, or any other invasive plant for that matter, you can volunteer to remove and destroy non-native plant species.
Butterflies are beautiful insects in the order Lepidoptera that many gardeners actively attract to their container gardens due to their beautiful wings, interesting flight patterns and interesting life cycle (egg, larva, pupa and adult). Some gardeners plant butterfly gardens to try and see many different butterfly species. Some butterflies migrate and can be seen only parts of the year.
