This will in part be due to a higher availability of nutrients and water in larger pots, but also because roots will get less pot-bound. Generally, plants planted in bigger pots will end up being larger on average plants increase 40–45% in biomass for a doubling in pot volume. The size of the pot will in part determine the size of the plants. The effect of pot size on the growth of maize.

Plastic pots come in a number of standard sizes, with a code indicating the approximate dimensions of the diameter at the top. An SP4 pot is commonly called a "4-inch" or "quart" container. Pots designated #1–#100 nominally have the volume of that many gallons, but in fact a #1 pot has a capacity of 0.625 gallons (a " trade gallon"). The sizes of plastic pots have been assigned an ANSI standard by the American Nursery and Landscape Association. Some types exist focusing on vegetables, whereas other paper pot systems exist that focus on larger plants (i.e. Also, for sale purposes, there is no need to recover the container as it is biodegradable and can not and does not need to be reused or recycled. Peat pots and paper pots are also being used, and have the advantage of facilitating transplanting as they do not need to be pulled out of a container for planting purposes (rather, the whole of container and plant is directly planted). Edibleculture), this is done by not letting the plastic growing pots leave the garden centre, and simply place the plant inside a cardboard (or newspaper ) sleeve for transportation. Some organisations (such as the Royal Horticultural Society) encourage the reuse of (plastic) plant pots and trays across their retail centres. In the nursery business, plants are generally grown in round or square plastic pots. Peat pots that are biodegradable and may be planted directly into the soil The traditional size for a long tom used for auriculas was 3 in diameter by 3.75 to 4 in depth. Other sources give different values, and sometimes names, for the smaller pots, for example The Gardener's Everyday Log Book while agreeing on "twos" to "thirty-twos" has two different types of "sixties" and disagrees on "thumbs" and "thimbles": NameĪ taller and thinner shape of pot, suitable for deep-rooting plants, was known as a long tom, a term still used. The traditional sizes were as follows, although others existed: They were made and sold by the cast, which is the number of pots produced from a given quantity of clay. The top of the flowerpot underneath the rim is commonly known as the shoulder or collar and can aid handling.įlower pots were traditionally made from terracotta. 287 BC, mentions that a plant called southern-wood was raised and propagated in pots because it was difficult to grow.
In Athens, earthenware flowerpots were thrown into the sea during the festival of the Gardens of Adonis. In the 18th century, Josiah Wedgwood's flowerpots or cachepots, were very popular they were often highly decorative and used as table centrepieces. Also Orchids, African violets and Pelargonium geraniums were shipped in pots from other parts of the world, including Africa, to North America and Europe. In the 18th century, pots were used to ship breadfruit seedlings from Tahiti to the West Indies. The Romans brought potted plants inside during cold weather. Through the centuries, the use of flowerpots has influenced the horticultural use of plants, and the Egyptians were among the first to use pots to move plants from one location to another. Purpose įlowerpots have a number of uses such as transporting plants to new locations, starting seeds, patio and indoor cultivation of plants, and the growing of tender plants in colder regions indoors. Recently, some flowerpots have been made with an automatic watering system, using a reservoir. The plant can use this water with its roots, as needed. There are usually holes in the bottom of pots, to allow excess water to flow out, sometimes to a saucer that is placed under the flowerpot. An example of biodegradable pots are ones made of heavy brown paper, cardboard, or peat moss in which young plants for transplanting are grown.įor seedling starting in commercial greenhouses or polytunnels, pots usually take the form of trays with cells, each cell acting as one small pot. Flowerpots are now often also made from plastic, metal, wood, stone, or sometimes biodegradable material. Historically, and still to a significant extent today, they are made from plain terracotta with no ceramic glaze, with a round shape, tapering inwards.
