Container gardening is especially adapted to present living. Plants in containers show great variety of form and texture. They can be used to create instant indoor gardens; they can be moved from one home to another; and they can be moved outdoors in the summer and indoors during the cooler months.
Space is not a problem. Container gardening can be conducted in a single pot on a table or window sill, in a more elaborate room divider, or in a built-in planter.
Just as there are many kinds of plants, there are many kinds of containers. Plants can be grown in any container that will hold a growing medium. The choice ranges from the common clay pot to cans, jars, boxes, baskets and tubs.
Most people select containers for both their practical and "esthetic qualities". These include cost, availability, weight, strength, durability, attractiveness and sentimental value.
The size and shape of the container should depend on the plant’s size and shape. Tall, tapering plants are more attractive in tall, relatively narrow containers. Short, compact plants appear more at home in shallow, wide containers.
Particularly important considerations for good plant growth are the volume and depth of the container, and some provision for drainage. Containers that have drainage holes in the bottom for the removal of excess water are best. Water-right containers are difficult to manage--excess water will accumulate at the bottom of the container and injure plant roots by excluding oxygen.
Container volume and depth become important in relation to the quantity of available water and nutrients.
Besides the right kind of container, some basic requirements for plant growth must be provided. Plants need light, water, nutrients, and a satisfactory temperature ranges.
Light is the most critical requirement. The levels of all the other requirements are regulated in relation to the amount of light that plants receive. When plants don’t have enough light they become tall and thin. Plants are easier to maintain in good condition when their light requirements are met.
