An enclosure for plants that protects plants against pests and other living organisms that may be harmful to plants. In one embodiment, a pot includes a first open-top container and a second open-top container. The first open-top container forms a first open space for housing a plant and includes an open top and an enclosed wall portion that forms a lateral perimeter of the first open-top container. The second open-top container forms a second open space for housing a pest-controlling substance that deters or attracts and traps pests. The second open-top container is coupled to the first open-top container along the lateral perimeter of the first open-top container. Additionally, the first open space is isolated from the second open space to prevent contents in the first open space from mixing with contents from the second open space.
