What You'll Learn
Plastic pots are lightweight, durable, and inexpensive
Plastic pots are a popular choice for gardeners due to their lightweight, durable, and inexpensive nature. They are versatile and easy to use, clean, maintain, and move around, making them perfect for any home or garden. Their high strength-to-weight ratio means they can be shipped worldwide and withstand the test of time.
Plastic pots are also very cost-effective, making them a preferred choice for many gardeners. They are available in various colours and sizes, and some premium plastic planters can even be made to resemble stone planters, giving them a rustic feel with all the benefits of plastic.
However, it is important to note that not all plastics are safe for gardening. Some plastics can leach chemicals, such as PFAS, phthalates, heavy metals, and PVC, which can be harmful to plant health and the environment. Therefore, it is crucial to choose the right type of plastic, especially if you are growing vegetables or food crops.
To ensure the safety of your plants and the environment, opt for non-toxic and biodegradable options. For example, fabric grow pots are made from 100% plant-based fabric and are available in various sizes. Alternatively, consider using materials like fiberglass, which is lightweight, durable, and known for its plant-protection qualities, including UV protection and waterproofing.
In conclusion, while plastic pots offer convenience and affordability, it is essential to be mindful of the potential health and environmental impacts of certain plastics. By choosing safer alternatives, gardeners can promote the well-being of their plants and the ecosystem as a whole.

Plastic pots are made of inert, recycled material
Plastic pots are a common sight in gardens and for good reason. They are durable, lightweight, and easy to move around. However, it is important to be mindful of the type of plastic we use in our gardens. Not all plastics are created equal, and some may leach chemicals into the soil, potentially affecting the plants and, by extension, those who consume them.
One of the key considerations when choosing plastic pots for gardening is to ensure they are made of inert and recycled materials. Inert materials, such as polypropylene, are safe to use as they do not undergo a meaningful chemical exchange with the surrounding environment. This means that chemicals from the pot are not transmitted into the soil or the plants themselves. Polypropylene pots, also known as HDPE (high-density polyethylene), are commonly used in the nursery pot market for small trees. They are known for their durability and safety, making them an excellent choice for gardeners.
Another advantage of using recycled materials is the reduction of plastic waste. Plastic waste is a significant contributor to pollution and global warming, and recycling helps combat this issue. Recycled plastic pots are often made from a variety of materials, including post-consumer recycled (PCR) plastics, which are retrieved from big-box stores where customers return used plastics. However, it's important to note that black plastic pots are challenging to recycle due to their carbon pigment and mixed-use plastics composition.
Some companies, like East Jordan Plastics, specialize in recycling horticultural plastics and creating new pots from them. Additionally, biodegradable pots made from bioplastics offer an eco-friendly alternative. These are created from biopolymers (plant or other biological material) or a blend of bio- and petrochemical-based polymers. They are more environmentally friendly due to their reduced use of fossil fuels, smaller carbon footprint, and faster decomposition compared to traditional plastics.
When choosing plastic pots for your garden, opt for those made from inert, recycled materials like polypropylene. This ensures the safety of your plants and contributes to a more sustainable future.

Plastic pots can overheat and release harmful chemicals
Plastic pots can get very hot and cause plants to overheat. Dark-coloured pots, such as black pots, are particularly susceptible to overheating as they absorb sunlight and convert it into heat. Pots left out in direct sunlight will also degrade, chip, and break more quickly.
Some plastic pots may also release harmful chemicals, such as PFAS, BPA, and phthalates, into the soil. However, the amount of chemical leach tends to be very small, and the toxicity levels are typically low. The type of plastic is an important factor—for example, polypropylene (#5) has a high heat tolerance and tends to leach less than other plastics. LDPE, used for semi-flexible plastic pots, is also considered very safe and not known to transmit chemicals into the soil or food. HDPE, used for heavy-duty nursery pots, is another safe option that is not known to transmit chemicals.
It is worth noting that the presence of organic matter in the soil can help catch leached chemicals and prevent them from reaching the roots of plants. Additionally, soil and water can reduce exposure to these chemicals. Nevertheless, it is recommended to avoid using plastic products marked with RIC 3, 6, and 7 for gardening, as they can leach dangerous chemicals.

Plastic is used in many forms in commercial crop growing
One of the most common uses of plastic in agriculture is plastic mulching, which involves placing a thin layer of plastic film over the ground, poking holes at regular intervals for seeds to be planted in, or placing it directly over plants in the early stages of growth. Plastic mulching helps to insulate and maintain a consistent temperature and humidity in the soil, prevent evaporation of moisture, minimize seed time and harvest, prevent weed growth, and prevent erosion. It also limits the amount of water that evaporates from the soil, which is extremely helpful in dry regions or areas experiencing drought. The use of black plastic mulch can also raise the soil temperature, helping plants grow more quickly and mature earlier compared to plants grown in bare ground.
Another use of plastic in agriculture is in the construction of greenhouses and high tunnels. Farm plastic is used as a durable and cost-effective replacement for glass in greenhouse and tunnel siding, allowing for the development of more efficient designs that capture more solar radiation while protecting crops from the elements. Polycarbonate (PC) is often used for greenhouse glazing applications. Polypropylene (PP) is a water-resistant material commonly used for bulk bags to store and transport crops and other materials, as well as agricultural plant packaging cord. Polyvinyl chloride (PVC) is ideal for tubing in irrigation and other hydroponic systems.
Plastic is also used to create lightweight crates for crop collection or display at farmers' markets, as well as for netting to guard against hail and create shade when needed. In addition, plastic pots and hoses are commonly used in gardening and agriculture. HDPE (high-density polyethylene) is considered safe for use in the garden and is used for heavy-duty nursery pots and irrigation piping. LDPE is also safe for use and is found in garden hoses, irrigation hoses, and semi-flexible plastic pots for growing plants.
