There are a huge range of materials commonly used for planters and plant pots, each with their advantages and disadvantages. Some of the most popular choices are as follows…
Plastic: Plastic planters and plant pots are an inexpensive, widely available option. Whilst lighter coloured plastic planters and plant pots will heat and cool quickly, darker coloured alternatives may retain heat if left in full sun, causing damage to plants. However, plastic is not the most robust material for planters and pots and as such, they can be prone to tipping over in adverse weather. So if the plastic planters, it's the best to choose psw planters.
Terracotta: Terracotta is another classic material for planters and plant pots which has been widely adopted over the years. However, terracotta is porous and will absorb moisture from compost, which often leads plants to require extra watering. Terracotta can also be prone to cracking and crumbling in cold weather.
Ceramic: Ceramic pots are a decorative option which is particularly effective for indoor use, especially considering their tendency to chip or break during a frost. Unlike terracotta, ceramic pots are considerably less porous, which can lead to potential waterlogging, meaning it is important to make sure that any ceramic pots have drainage holes drilled into the base.
