  3. Plant the seeds in the seed starting mix
  4. Water the mix so that it is moist but not soggy
  5. Place plastic wrap over the top of the container

  7. Once sprouts appear, transplant the seeds to a container filled with soil that has a pH level between 5 to 7

String of Turtles Growing Conditions


To care for a tropical succulent-like plant, you may need to invest in the following items:

These plants require tropical conditions in order to grow strong and healthy, so they will need extra heat and humidity sources when they are kept in air-conditioned or heated homes.  Ideally, this tropical plant should be kept in a spot that is away from vents and doors and has temperatures ranging between 68 and 75 degrees Fahrenheit. 

How to Plant String of Turtles

You should only need to repot your String of Turtles plant every two to three years.  This is because most Peperomia varieties enjoy being tight and cozy in their plant containers

Nevertheless, repotting these plants every few years will provide them with new soil that contains fresh nutrients and it will reduce the risk of pest infestations and diseases that can reside in old soil and dirty plant containers.

Keep an eye out for the following signs to know whether or not your plant needs repotted before two to three years has passed:

  • Compacted Soil
  • Roots that are crowded and growing into a ball formation
  • A plant that looks too big for its current container

When it comes time to repot your Rainbow Peperomia, follow these steps:

  1. Fill a container with potting soil (if the plant has outgrown its current container, choose a new container that is two inches larger in diameter)
  2. Create a hole in the soil for the plant to set inside
  3. Carefully remove the plant from its current container 
  4. Softly dust off any excess soil from the roots of the plant
  5. Set the plant into the hole in the new container
  6. Disperse the soil around the base of the plant and check that it is secure in its new container
  7. Lightly water the plant
  8. Set it in a warm spot with indirect sunlight

Note: Repotting should only be done on warm spring days to reduce the risk of the plant going into shock

String of Turtles Water Requirements

Root rot is a big deal to these plants, so it is necessary to learn how to properly water them or you will be dealing with a dead or dying plant very quickly.  Peperomia plants should be watered using the soak and dry method.  It is a very simple method with six steps:

  1. Test the plant’s soil before watering it.  It should only be watered if the top two inches of soil is completely dry.  If it is still moist, wait another day to water it.
  2. Fill a tray or a tub with water.
  3. Set the plant container in the water, but make sure the water isn’t so deep that it will overflow the lip of the container. The point of the soak and dry method is to utilize the drainage holes in the plant container to soak up water from the bottom.
  4. Let the plant soak up water for fifteen minutes.
  5. Remove the plant from the water.
  6. Set the plant in a spot where the excess water can drain from the container’s drainage holes.

Root rot infesting your plants should not scare you.  If you really want to make sure all your plants are getting the proper amount of water in the proper method, consider downloading a plant watering app.  These apps are capable of reducing or removing any worries you may have about watering your plants. 

They are designed to keep track of when you watered your plants, to remind you to water your plants, and to answer questions about your plants.  No more watering worries now.

String of Turtles Light Requirements

Proper lighting is another essential care factor when it comes to all varieties of Peperomia.  They all have delicate leaves that can easily burn and wither from exposure to direct sunlight, so if you want to successfully grow this plant, then provide it with bright or low light that is either filtered or shaded.  

Test your indoor spaces with either a light meter or a light meter app to ensure that your plants are receiving adequate lighting.  If you cannot provide your String of Turtles plant with adequate natural light, they grow very well under artificial grow lights.
