Plastic pots are vulnerable to sun damage, which can cause them to crack and break. To protect your plastic pots from sun damage, you can use a variety of methods, such as painting them with UV-resistant paint, wrapping them in foil, or covering them with a layer of protective material such as varnish, wrapping paper, or glue. Additionally, using light-coloured pots that reflect sunlight can help keep the planters cooler, and double potting can also be an effective method.
How to protect plastic pots from the sun:
| Characteristics | Values |

| Paint type | Acrylic varnish |
| Mulch | Organic mulch keeps roots cooler |
| Double potting | Place a smaller pot inside a larger pot |
| Wrapping | Wrap pots in foil, wrapping paper, burlap, or aluminium foil |
| Tape | Tape can be used to cover pots, but it may degrade |
| Varnish | Varnish can be used to protect paint from cracking or fading |
| Decorations | Glue decorations such as ribbons, beads, glass stones, shells, or pebbles to the pot |

What You'll Learn
Use light-coloured pots to reflect sunlight
When choosing a pot for your plants, it is important to consider the colour. Dark-coloured pots, such as black pots, retain a lot of heat during the summer and can end up cooking and killing the root ball in hot weather.
To protect your plastic pots from the sun, opt for light-coloured pots that reflect sunlight and keep the planters cooler. For instance, you can use white fabric pots or white plastic pots. However, keep in mind that constant sun exposure can cause the plastic to become brittle and crack over time. To prevent this, look for white plastic pots made from HDPE plastic, which has good UV resistance.
If you already have dark-coloured plastic pots, you can paint them a light colour to help reflect sunlight. Use a plastic primer and gloss white paint, allowing enough time for the paint to cure. Alternatively, you can wrap your dark pots in foil or varnish them with acrylic varnish to protect them from the sun.

Double potting: put a smaller pot inside a larger one
Double potting is a useful method to protect your plants from the sun's heat. It involves placing a smaller pot inside a larger one, which creates an additional layer of insulation, protecting roots from extreme heat. This method is particularly useful if you want to use decorative pots that don't have drainage holes.
First, pot your plant in a plain grow pot, also known as a cache pot. This is a French term meaning "pot hider". Then, place the grow pot inside the decorative container of your choice. This way, you can still use the decorative pot you want, while also ensuring your plant is in a pot with proper drainage.
Double potting also makes it easy to replace the plant if it's not doing well in your growing conditions. You can simply lift the grow pot out of the decorative pot and replace it with a new plant. Additionally, if your decorative pot doesn't have drainage, it can still be useful to catch excess water and act as a saucer.
To further protect your plants from the sun, consider using terracotta pots, which offer natural insulation due to their porous nature. Elevating terracotta pots slightly off the ground with pot stands or bricks can also help reduce the risk of overheating.

Use a layer of shredded bark, compost, pine needles or other organic mulch
Plastic pots, especially those that are black, can retain a lot of heat in the summer, which may cook and kill the root ball in hot weather. To protect your plastic pots from the sun, you can use a layer of shredded bark, compost, pine needles, or other organic mulch. This will slow evaporation and keep the roots of your plants cooler.
Organic mulches are preferable to inorganic mulches, such as pebbles, which collect and hold heat. In addition, you can try shading the roots of your plants with shade cloth, mesh, scraps of window screening, or a carefully placed beach umbrella.
You can also try to protect your plastic pots from the sun by using light-coloured pots, which reflect sunlight and keep planters cooler. Terracotta, concrete, or thick, glazed ceramic will keep plants cooler more efficiently than plastic. Alternatively, you can try double potting, which involves putting a smaller pot inside a larger pot. Be sure that both pots have drainage holes and never let the inner pot stand in water.
Another option is to use a product like Rustoleum spray paint for plastic. If you use their plastic primer followed by their gloss white, it can be pretty durable in the sun. You can also wrap your pots in foil or burlap, or switch to fabric pots, which do not get as hot.

Avoid placing pots where light is reflected from walls or fences
When placing your plastic pots, be cautious of areas where light is reflected from walls or fences. This reflected light can cause extreme heat for your plants, which can be detrimental to their health. Instead, opt for locations that provide morning sun exposure but shield your plants from intense afternoon sunlight.
You can also address this issue by employing shade cloth, mesh, or even a strategically placed beach umbrella to create a shaded environment for your plants. This is particularly crucial if your deck or patio faces south or west, as these orientations experience higher temperatures during the summer.
Another creative solution is to utilise light-coloured pots that reflect sunlight effectively. Opt for materials like terracotta, concrete, or thick, glazed ceramic instead of plastic to enhance cooling. Additionally, consider double potting, which involves placing a smaller pot inside a larger one, ensuring that both pots have adequate drainage holes.
To further protect your plants from the sun's rays, you can apply a layer of shredded bark, compost, pine needles, or other organic mulch. This organic layer slows evaporation and maintains cooler root temperatures. However, avoid using pebbles or inorganic mulches that tend to collect and retain heat, potentially harming your plants.

Use spray paint for plastic
Spray paint is an excellent way to rejuvenate faded plastic plant pots and protect them from further sun damage. It is a simple and cost-effective method to transform the appearance of your plastic pots and make them look as good as new.
Preparation
Before you begin spray painting, it is essential to prepare the plastic pot to ensure the paint adheres well and the finish is smooth and durable. Start by cleaning the pot with soap and water or using alcohol or nail varnish remover to eliminate any dirt or grime. Once the pot is clean and dry, sand the surface to create a rough texture, which will help the paint stick better. You can use a product like Sander Deglosser to rub down the exterior, removing the shiny outer layer.
Painting Technique
Place the pot upside down on a drop cloth or board to protect the surrounding area from paint. Shake the spray paint can for at least two minutes, as instructed on the can, to ensure the paint is thoroughly mixed. Spray the bottom of the pot and any ledge or lip with a light coat of paint. Allow this first coat to dry for about an hour, then turn the pot over and apply another light coat of spray paint. Continue with light coats rather than a heavy coat to achieve a smooth and drip-free finish. Apply additional coats as needed until you achieve the desired coverage and colour depth.
Sealant
Once you are happy with the paint job, consider applying a coat or two of sealant to protect the pot from UV damage and give it a glossy finish. This step will help prevent the paint from cracking or fading due to sun exposure.
Tips
- When spraying, try to keep your movements steady and fluid to avoid uneven paint coverage and drips.
- Work in a well-ventilated area and wear a mask to avoid inhaling paint fumes.
- Choose a paint specifically designed for use on plastic, such as Rust-Oleum Painter's Touch Spray Paint, to ensure durability and adhesion.

Frequently asked questions
To protect your plastic pots from the sun, try switching to light-coloured pots, which reflect sunlight and keep planters cooler. Alternatively, you can paint your plastic pots with a light-coloured paint, such as gloss white, which will be durable in the sun.
You can cover your plastic pots with wrapping paper, glue and varnish. You can also glue decorative items, such as glass stones, shells, or sticks, to your plastic pots.
Tape will degrade unless you use a large amount to create a shell on the outside, but then the amount of good tape will cost more than a replacement. Similarly, glue will only be effective if you use it with a protective layer of varnish.
