Why Wash New Plant Pots

When you purchase new plant pots, you may wonder if it is necessary to wash them before using them. The short answer is yes, you should wash new plant pots before using them to plant your flowers or other plants. Here are a few reasons why:
Remove Dirt and Debris
New plant pots may have dirt, debris, or other contaminants on them from the manufacturing process or from being stored in a warehouse. Washing them will help remove any dirt or debris that could harm your plants.
Prevent the Spread of Disease
Washing new plant pots can also help prevent the spread of disease. If the pots have been used before, they may have been contaminated with soil-borne diseases that could harm your new plants. Washing the pots with a solution of one part bleach to nine parts water can help kill any bacteria or fungi that may be present.
Better Drainage
Sometimes, the drainage holes in new pots can be clogged with dirt or debris. By washing the pots, you can ensure that the drainage holes are clear and that water can flow freely through the soil.
Environmentally Friendly
By reusing pots instead of buying new ones, you can reduce the amount of plastic waste that ends up in landfills. You can help reduce your carbon footprint and do your part for the environment.
Potential Contaminants in New Pots

When you purchase a new plant pot, you might assume that it is clean and ready to use. However, there are potential contaminants that could be present in new pots that may harm your plants. Here are some of the possible contaminants you should be aware of:
- Dirt and Debris: New pots may have dirt and debris from the manufacturing process or from sitting on a store shelf. This dirt may contain bacteria, fungi, and other pathogens that could harm your plants.
- Diseased Plants: If the pot was previously used to grow a diseased plant, the pot may still contain disease organisms that could infect your new plant.
- Insects and Pests: New pots may have insects or pests hiding in the soil or in the pot itself. These pests could damage or kill your new plant.
- Fungus and Mold: If the pot has been stored in a damp environment, it may have fungus or mold growing on it. This can spread to your new plant and cause problems.
How To Clean Plant Pots
To avoid these potential contaminants, it is a good idea to wash new pots before using them. This will help remove any dirt, debris, or disease organisms that may be present. You can use a mild soap and water to clean the pot, or you can use a 10% bleach solution to disinfect it. Be sure to rinse the pot thoroughly after washing to remove any soap or bleach residue.
In addition to washing new pots, you may also want to consider using a potting mix that is specifically formulated to be sterile. This can help ensure that your new plant is not exposed to any harmful pathogens or contaminants.
How to Clean Different Types of Pots

Plastic Pots
Plastic pots are easy to clean. You can use a solution of one part bleach to nine parts water to sanitize them. For an eco-friendly option, sterilize plant pots with vinegar. Use a solution of one part vinegar to one part water. Scrub the pots with a sponge or wire-bristle brush, and rinse them thoroughly with water.
Terracotta and Clay Pots
Terracotta and clay pots are porous, which means they can absorb water and other liquids. To disinfect the pots, start by using a brush or rag to remove all the loose soil particles.
Then wash pots in soapy water (dish detergent works great) and rinse clean. If you want to remove stains, mix baking soda with water to make a paste.
Apply the paste to the pot and scrub it with a brush. Rinse with water and let the pot dry completely before using it again.
Metal Pots
Metal pots are durable and easy to clean. You can wash them with soapy water and a sponge or use a dishwasher. If the pot has rust, you can use steel wool to remove it. Be sure to wear gloves and goggles to protect your hands and eyes.
Ceramic Pots
Ceramic pots are delicate and can easily break. To clean them, use a sponge or soft cloth with soapy water. Be gentle and avoid using abrasive cleaners that can scratch the surface. Rinse the pot with water and let it dry completely before using it again.
Disinfecting New Pots
New pots can harbor harmful bacteria, fungi, and pests that can infect your plants and soil. Disinfecting new pots is a simple process that can help prevent the spread of diseases and pests in your garden.
One of the easiest and most effective ways to disinfect new pots is by using household bleach. Mix one part bleach with nine parts water to create a solution that is safe for most types of pots.
Dip the pots in the solution and let them soak for at least 10 minutes. Rinse the pots thoroughly with clean water and let them dry completely before using them.
In addition to disinfecting new pots, it’s also important to clean and disinfect your existing pots regularly. This can help prevent the spread of diseases and pests in your garden and keep your plants healthy.
Use a solution of bleach and water or another disinfectant to clean your pots, and be sure to rinse them thoroughly and let them dry completely before using them again.
How to disinfect plastic plant pots without bleach
If you prefer not to use bleach, there are other disinfectants you can use. Lysol is a popular disinfectant that can be used to clean and disinfect new pots. Simply spray the pots with Lysol and let them dry completely before using them.
Other options:
- White vinegar: Mix 1 part white vinegar with 3 parts water and use a sponge or cloth to wipe down the pots. Let them air dry.
- Hydrogen peroxide: Mix 1 part hydrogen peroxide with 4 parts water and use a spray bottle to apply the solution to the pots. Let them air dry.
- Alcohol: Mix 70% isopropyl alcohol with water and use a spray bottle to apply the solution to the pots. Let them air dry.
- Hot water: If the plastic pots are heat-resistant, you can pour boiling water over them or soak them in a tub of hot water for several minutes to disinfect them.
Remember to always wear gloves when handling cleaning solutions, and thoroughly rinse the pots with water before using them again.
It’s important to note that not all types of pots can be disinfected with bleach or other disinfectants. Terracotta and other porous pots can absorb the disinfectant, which can harm your plants. If you’re unsure whether a pot can be disinfected, check with the manufacturer or use a different disinfectant.
Dealing with Mineral and Salt Deposits
When you water your plants, minerals and salts can build up in the potting soil and on the surface of the pot. Over time, these deposits can harm your plants by preventing water from reaching the roots and causing root burn. Here are some tips to help you deal with mineral and salt deposits in your plant pots:
- Leach the soil: To reduce mineral buildup, water your plants with clear water to leach (rinse) the potting soil every 4 to 6 months. Apply at least 3 times the volume of the pot of fresh water on the potting soil and let it drain completely. This will help flush out excess minerals and salts from the soil.
- Replace the pot: If a crust forms on the outside of a pot, it may be time to replace it with a fresh one. This is because the buildup of minerals and salts can be difficult to remove and may harm your plant in the long run.
- Scrub the pot: If you want to reuse an old pot, you can scrub it with a steel wool or a wire-bristle brush to remove mineral deposits and other debris. If mineral deposits remain, use a knife to scrape them off. Rinse pots thoroughly and soak them in a bucket of clean water until you are ready to use them.
- Use vinegar: If you have clay pots, you can use a mixture of white vinegar and water (20 parts water and 1 part vinegar) to clean the material. Soak the pot for thirty minutes in the vinegar solution, then scrub off any remaining residue with a brush. This will help remove any mineral and salt deposits that may have built up on the surface of the pot.
Reusing and Recycling Plant Pots

Instead of buying new pots every time you want to plant something, you can simply reuse the ones you already have. However, before you start reusing your old pots, it’s important to make sure they are cleaned and emptied properly.
If you’re reusing plastic pots, it’s important to clean them thoroughly before planting new plants or reusing the same pot. Cleaning pots or containers before planting new plants or reusing the same pot is important to minimize pests and pathogens. Diseases can get passed on in the soil which can affect your new or repotted plants from thriving.
On the other hand, some think that disinfecting pots with bleach is unnecessary and does little to curb pests and diseases. In fact, your plant is more likely to “catch” these kinds of problems from poor growing conditions and bad habits than from dirty pots.
Whether you choose to clean your pots or not, it’s important to empty them of any soil or plant debris before reusing them. This will help prevent the buildup of harmful pathogens and pests that can damage your plants.
Proper Drying and Storage of Pots

When you’re finished washing your plant pots, it’s important to let them air dry thoroughly before storing them. This will help prevent the growth of mold or bacteria, which can harm your plants.
You can place the pots upside down on a clean towel or drying rack to allow them to dry completely. Make sure that there is enough air circulation around the pots to help them dry faster.
If you live in a humid climate or during the winter season, it may take longer for your pots to dry. In this case, you can place them near a fan or in a well-ventilated area to help speed up the drying process. It’s important to make sure that your pots are completely dry before storing them to avoid any potential damage.
Once your pots are dry, you can stack them neatly in a dry and cool place. If you have a lot of pots, you can use a shelving unit to keep them organized. Make sure to label each pot with the type of plant that was grown in it, so you can easily identify it later.
Proper drying and storage of your plant pots is important to maintain their longevity and cleanliness, which in turn will help keep your plants healthy.
Additional Tips for Healthy Plants
Now that you know whether or not to wash new plant pots, here are some additional tips to keep your plants healthy and productive.
Choose the Right Container
When it comes to choosing containers for your plants, there are several factors to consider. First, make sure the container is the right size for your plant. If it’s too small, your plant won’t have enough room to grow. If it’s too large, your plant may become waterlogged and develop root rot.
Second, consider the material of the container. Plastic containers are lightweight and easy to move around, but they may not be as durable as other materials. Terracotta containers are porous and can help regulate moisture levels, but they may break more easily than other materials.
Use the Right Soil
The type of soil you use can have a big impact on the health of your plants. Make sure to use a high-quality potting soil that is appropriate for your plant’s needs. Some plants, like succulents, require well-draining soil, while others, like ferns, prefer soil that is consistently moist.
Provide Adequate Sunlight
Most plants require sunlight to grow and thrive. Make sure to place your plants in a spot where they can get the right amount of sunlight for their needs. Some plants, like herbs, require full sun, while others, like ferns, prefer shade.
Water Properly
Watering your plants properly is key to their health and productivity. Make sure to water your plants when the soil is dry to the touch, but don’t overwater them. Overwatering can lead to root rot and other problems.
Repot When Necessary
As your plants grow, they may outgrow their containers. If you notice that your plant’s roots are starting to grow out of the drainage holes in the bottom of the container, it’s time to repot.
Use Linseed or Tung Oil
If you want to protect your plant containers from the elements and extend their lifespan, consider using linseed or tung oil. These oils can help protect the containers from water damage and other problems.
Provide Nutrients
Plants need nutrients to grow and thrive. Make sure to fertilize your plants regularly with a high-quality fertilizer that is appropriate for their needs.
Sow Seeds Properly
If you’re starting plants from seeds, make sure to sow them properly. Follow the instructions on the seed packet to ensure that your seeds have the best chance of germinating and growing into healthy plants.
Use Trays and Saucers
Using trays and saucers can help protect your floors and furniture from water damage. Make sure to choose trays and saucers that are the right size for your containers.
By following these tips, you can help ensure that your plants are healthy, productive, and beautiful.
