White residue
If your terra cotta pot is coated in a white residue, don’t panic. It’s nothing more than salt deposits, and won’t hurt you or your plant. When you water your plant with hard water, which is what most tap water is, dissolved salts end up in your soil. Since terra cotta is porous, some of the water will evaporate through the sides of the pot. When this happens, the water goes into the air and the salt is left behind. This process can happen with any porous material and is called efflorescence....
Green film
If there is a green film on your terra pot this is due to algae. While it’s less likely you will encounter algae indoors, it can definitely be an issue outdoors or in an area near a humidifier. Algae won’t hurt your pot or your plant and I personally think it adds a little something extra to your pot. Kind of like 2 plants for one.
Mold
Occasionally, with terra cotta, you will also see a black film or a white fluffy substance on the outside of your pot. This is mold. Since terra cotta is porous and the material is often damp, it is an ideal place for mold to grow. Mold on the outside of your pot shouldn’t hurt your plant, but you don’t want it spreading through your house. No one likes the look of mold, so this is one you definitely want to get rid of.
White residue
To prevent salt from building up on the outside of your pot there are a few methods you can try. The first is to use filtered water or rainwater when you water your plants. Since the main cause of white residue is salt and most of that salt is coming from your tap water, eliminating tap water from your plant care routine can majorly cut down on the amount of salt that is left behind on your pot. The second way you can prevent salt buildup is by using a diluted fertilizer. There are lots of mi...
Algae and Mold
To prevent algae and mold on your pot, you canseal it with rustoleum or flex seal. This will prevent water from evaporating through the surface of the pot and providing the algae and mold with water. Without water, the mold and algae won’t be able to survive and won’t grow. You can also prevent algae by regularly spraying the outside of the pot with diluted bleach. This will prevent algae and fungus from growing. If your plant is tolerant of sunlight, you can also place the pot into direct su...
White residue/Salt
Having salt buildup on the outside of your terra cotta pot won’t hurt most plants. The exception to this is trailing plants whose stems may come in contact with the salt. Salt is not good to have directly on stems, leaves, or roots of plants. Salt buildup on the inside of your pot shouldn’t hurt your plant either, but it could be a sign you have too much salt in your soil. Try to flush your soil once a month to cut down on the amount of salt. To flush your soil, use 4x the amount of filtered...
Algae
Having algae on your terra cotta pot will not hurt your plant in any way. Even if trailing plants touch the algae, they will be fine. It’s basically just another plant hanging out nearby.
Mold and fungus
Having mold and fungus on your pot is not ideal. It can harm your plant if it reaches the roots and breathing it in can be bad for you. You will want to get rid of any mold or fungus on your pot as soon as you spot it.
White residue/salt buildup
The best time to rid your pots of salt buildup is in the spring when you are repotting your plants. Be sure the pot is empty when trying to remove salt buildup as this method could hurt your plant. To start, you will want to create a mixture of 1 part vinegar to 4 parts water. Place your empty pot in the solution and allow it to soak for about an hour. This will loosen the top layer of residue and allow it to come off when you get to the next step. For step 2, you will want to scrub the pot w...
Algae
Removing algae is a relatively easy process, especially compared to the salt. Simply wash the pot in hot soapy water the same as you would your dishes. The algae should come off pretty easily with a little scrubbing.
Mold/Fungus
To remove mildew from terra cotta, you will want to either soak the pot in diluted bleach for 10 minutes, then take it out and wash it with soap and water. Or, you can spray hydrogen peroxide onto the mold. Let it sit for approximately 5 minutes, and then wash it in hot soapy water. Both methods should work well at removing mold and fungus.

There are some plants that really thrive in terra cotta plants. Most succulents, cacti, philodendrons, and snake plants do really well in terra cotta.
