What Kind of Soil Does a String of Turtles Plant Require? (Best Soil Mix)
The String of Turtles is semi-succulent, which has different soil requirements than most plants or succulents. Unlike most succulents that grow in dry areas, String of Turtles is native to moist Brazilian rainforests, so it is not suitable to use sandy soil or premixed soil that has been formulated especially for cactus or succulents. Meanwhile, though it is native to rainforests, it is afraid of overwatering or waterlogging because it has succulent-like leaves that store water. It is best to use well-drained soil that replicates its natural environments at the same time.

There are many factors to consider while choosing the right soil mix for your String of Turtles plant. With that in mind let’s find out what kind of soil does String of Turtles needs?

Soaking soil is the easiest way to kill your string of turtles plant with root rot. A well-drained soil/mix is necessary. To keep the plants thriving and beautiful, we need to mimic the properties of the natural soil, which should be nutrient-rich and remain slightly damp while not soggy or waterlogged.

Components of String of Turtles Plant Soil Mix

​​Before making the soil for String of Turtles, we should know that each ingredient in the potting mix should have a specific function. Think about these questions:
 
  • Can it increase the drainage ability? 
  • Can it offer necessary nutrition for plants?
  • Can it improve aeration in the soil?
  • Can it improve water retention capacity?
  • Does it contain harmful microorganisms or weed seeds?
  • How will it adjust the soil PH?

After considering these problems, the best components to mix soil for string of turtles include:

Sphagnum Peat Moss

Peat moss also called sphagnum peat moss, has superior moisture management capacity since it doesn’t compact or break down readily. It contains much of the dead material in a peat bog that comes from sphagnum moss that grew on top of the bog and has an acid pH, doing wonders for string of turtles soil pH balance and nutritional content. Peat moss doesn’t contain harmful microorganisms or weed seeds.

Coconut Coir

Because it is pH neutral, readily available, and lightweight, Coconut Coir is an excellent String of Turtles plant potting mix component.
  • High water retention capacity.
  • Acceptable pH & EC.
  • Ability to retain nutrients against leaching and to buffer supply.
  • Good drainage/aeration.
  • Less shrinkage.
  • Retains physical properties longer.

Perlite & Vermiculite

Both perlite and vermiculite are beneficial to aeration and water retention for String of Turtles soil. Compared with vermiculite, perlite is more porous and allows soil mix to drain water more efficiently. Meanwhile, perlite is also pH neutral and naturally pasteurized.

Sand

If you don’t have access to perlite or vermiculite, coarse sand will serve a similar function. It is the least expensive aeration and water retention medium. Make sure that it is coarse enough for better drainage and aeration.

Ideal Soil pH for String of Turtles Plants

In terms of acidity, soil with a pH between 5 and 7 is ideal for String of Turtles plant. We can adjust the soil pH by changing the percentage of soil components or adding other components. Peat moss and coco coir, can cause the soil pH to tip towards the acidic side. 

Testing the soil is every so often is a good idea. If the soil is too acid (less than 5.0), adding limestone will be useful. If the soil is too alkaline (above 7.0), you can add more sphagnum peat moss or coco coir.
