Container garden or Pot gaden

Container gardening is the practice of growing plants exclusively in containers instead of planting them in the ground. Pots, traditionally made of terracotta but now more commonly plastic, and windowboxes 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 can also make this option appealing to the gardener.

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

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 form of container gardening.

Repotting

Repotting 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 repotted according to the size of their root system. Most plants need to be repotted every few years, because they become "pot-bound" or "root-bound."
