Container gardening or pot gardening is the practice of growing plants, including edible plants, exclusively in containers instead of planting them in the ground. A container in gardening is a small, enclosed and usually portable object used for displaying live flowers or plants. It may take the form of a pot, box, tub, pot, basket, tin, barrel or hanging basket.

Methods
Pots, traditionally made of terracotta but now more commonly plastic, and window boxes have been the most commonly seen. Small pots are commonly called flowerpots. In some cases, this method of growing is used for ornamental purposes. This method is also useful in areas where the soil or climate is unsuitable for the plant or crop in question. Using a container is also generally necessary for houseplants. Limited growing space, or growing space that is paved over, can also make this option appealing to the gardener. Additionally, this method is popular for urban horticulture on balconies of apartments and condominiums where gardeners lack the access to the ground for a traditional garden.
Planting
Containers range from simple plastic pots, teacups to complex automatic-watering irrigation systems. This flexibility in design is another reason container gardening is popular with growers. They can be found on porches, front steps, and in urban locations, on rooftops. Sub-irrigated planters (SIP) are a type of container that may be used in container gardens. Potting material must be loose and allow drainage to offer proper aeration for roots to breathe, preventing root rot.
Re-potting
Re-potting is the action of placing an already potted plant into a larger or smaller pot. A pot that fits a plant's root system better is normally used. Plants are usually re-potted according to the size of their root system. Most plants need to be re-potted every few years, because they become "pot-bound" or "root-bound." Plants' roots can sense its surroundings, including the size of the pot it is in, and increasing the pot size allows plant size to increase proportionally.
Advantages
Many types of plants are suitable for the container, including decorative flowers, herbs, cacti, vegetables, and small trees. There are many advantages to growing plants in containers, namely:
- Less risk of soil-borne disease
- Virtually eliminate weed problems
- Mobile plants gives more control over moisture, sunlight & temperature
