Best Pothos Soil Mix – The Essentials
Pothos plants do best with a well-draining soil mix that balances water-holding capacity and drainage. The soil pH should be between 6.0-6.5. A good mix is two parts peat moss to one part perlite to one part pine bark fines.
The Role of Soil in Plant Health
Proper soil is essential for good plant health. Most natural soil is a mix of three types of inert particles (sand, silt, and clay), as well as organic matter.
Many houseplant soil mixes are made from inert materials such as vermiculite and perlite as well as organic materials like coco coir and peat moss.
No matter the composition of the soil, it should do the following:
● Provide the right mix of water holding and drainage
● Hold and cycle nutrients
● Anchor the plant in place
● Provide proper aeration
If you use the wrong soil mix, your plant can face several problems. A soil mix that doesn’t provide enough aeration or draining can lead to problems with root rot and oxygen exchange. Alternatively, soils that don’t hold enough water can lead to dry plants.
The proper soil mix is also essential to providing plants with nutrients. The pH of the soil affects nutrient availability.
Additionally, the soil structure impacts how well the soil holds nutrients. Certain types of clay and organic matter particles are great at holding nutrients until plants need them.
Common Signs You’re Using the Wrong Soil Mix for Pothos Plants
If you’re using the wrong type of soil for your Pothos plant, you’ll likely notice one or more indicators. Both your plant and the soil itself will show you that you need to choose a different soil.
While yellow leaves can be a sign of a variety of Pothos problems, they are often a signal that you’re using the wrong soil mix.
Yellow leaves often appear when your plant doesn’t have access to oxygen. If you are using soil that doesn’t provide proper drainage, your plant’s roots cannot access the oxygen they need.
Yellow leaves can also be an indicator of root rot. While root rot is caused by a fungus, it often appears in wet conditions. Allowing your soil to dry out between waterings will help prevent root rot. For this to happen, you need to use a well-draining soil mix!
Soft Plant Tissue
If you notice your plant’s roots or above-ground tissue is soft, it might be experiencing fungal issues. These fungal issues often appear when a plant is constantly in wet soil.
If you notice any soft tissue, check your soil. Excess water should drain out the bottom, rather than sit in the soil.
When you water your plant, the soil should become moist. However, the excess water should drain out of the bottom of the planter, rather than remain in the soil.
The soil should also dry out over time. Environmental conditions impact how fast the soil should dry, but the top two inches of soil should be dry within one to three weeks.
If you notice the top of your soil is constantly wet, your soil is not draining. This is a sign that you need to choose a different potting soil for your Pothos plant.
The Importance of Well-Draining Potting Soil for Pothos Plants
One of the most important aspects of a good Pothos soil is proper drainage. If your soil doesn’t allow excess water to escape, you’ll end up with water-logged soil that your plants will hate.
When soil isn’t well-draining, air pockets stay filled with water. This means that plant roots don’t have access to oxygen — essentially, they’re drowning!
Soils that aren’t well-draining also create problems with root rot and other types of fungal and bacterial issues.
What Soil pH Levels are Best for Pothos Plants?
All varieties of Pothos plants prefer soil with a pH between 6.0 and 6.5. If the pH is a little outside of this range, your plants will be fine.
How Plant Size and Pot Type Affect Soil
You may be wondering if the size of your Pothos plant and/or the type of planter impact what soil you should choose. For the most part, the answer is no.
All Pothos plants should be planted in a well-draining soil mix with a slightly acidic pH. The size of the plant nor the type of container it’s planted in affects this.
With that said, these two factors do impact how you should water. A larger planter will hold more soil, which will dry slower than soil in a small pot. This means you will need to water your plant less frequently.
However, large plants will also use more water than smaller plants. So large plants may need to be watered more often, even if they’re in a larger container.
The resounding answer is that the type and size of your Pothos plant as well as the type and size of your planter do not change the soil you should use.
Best Potting Soil for Repotting Pothos Plants
When you re-pot your Pothos plant you don’t need to alter the type of soil you use; these plants will still like a well-draining soil mix.
However, when you repot, it’s a good practice to dust off the old soil and replace it with new potting soil. This will prevent the spread of pathogens and elevate any issues with compaction.
