Like most other types of flower pots, plastic flower pots have several advantages and disadvantages. First, plastic pots are generally very strong and flexible, but if they do get damaged, they are inexpensive to replace. Plastic pots can also be found in a wide range of colors and styles to match nearly any type of décor, and they are very lightweight. These types of pots are also not as porous as clay or terra cotta pots, however, and this can cause them to hold excess water.
One of the biggest advantages of plastic flower pots is their strength. Heavy plastic is generally a very strong and durable material, and pots made from this material are less likely to break than pots made from clay. Plastic pots are also flexible to a certain degree, whereas clay pots are not. On the other hand, plastic pots are much more likely to crack than metal flower pots.
Plastic flower pots can get broken, but gardeners usually do not need to spend much to replace them. Gardeners on a budget usually prefer plastic pots, because they are inexpensive. Several of these pots can often be purchased for the same price as one terra cotta or metal pot.
Flower pots made from plastic can also be found in nearly any color and style. Some may be brightly colored, for example, while others can be molded to resemble more ornate metal or ceramic flower pots. This wide range of choices makes it easy for a gardener to choose a flower pot to match his décor.
Another major advantage of plastic flower pots is their weight. Since plastic is a much lighter material than clay or metal, plastic flower pots are much lighter than flower pots made from other materials. The weight of these pots often makes it much easier to move plants around when necessary. Some gardeners may not even be able to lift a large terra cotta pot filled with dirt.
Unlike terra cotta pots, however, plastic flower pots are not porous. This means that instead of water leaching out the bottom and sides of the pot, it can become trapped in it. An excessive amount of water pooling in a flower pot will often damage the plant's roots. As a general rule, gardeners should make sure that their plastic flower pots have enough drainage holes in the bottom to allow water to escape.
