Best Well-Draining Potting Soil (Commercial + DIY Guide)

Do you know how critical potting soil health is for the plant’s overall health?

The stunted growth, burned foliage, bacterial growth, and root rot are all linked to the wrong potting soil.

In fact, many houseplants thrive in well-draining potting soil with only enough moisture and lots of oxygen.

Well-draining potting soil allows water drainage at a medium rate and promotes air pockets for oxygen circulation. You can choose a mix of organic/inorganic matters like peat moss, coco coir, perlite, vermiculite, chips, barks, and sand for your House plants.

A well-draining potting mix is appropriate for most houseplants.

However, finding the best combination ratio is essential to make the perfect well-draining soil mix.

Read on to find out how to make perfect well-draining potting soil at home or where to buy one.

What is a Well-Draining Potting Soil?

If you have grown many houseplants, you would know how different soil types will affect the plant’s health.

Also known as well-draining soil, the potting mix allows water to drain quickly, keeping the soil evenly moist.

The compact soil will choke the plant roots, depriving them of water and oxygen, while continuously moist soil will drown the roots.

Well draining potting mix
Well-draining potting soil materials include both organic and inorganic matter.

Both cases may negatively affect plant growth unless growing succulents and Bee Balm. These plants thrive in compact or wet soil, requiring a perfect soil mix that drains steadily.

If you are wondering, most plants like Monstera, Anthurium, Pothos, Fiddle-leaf, and flowering species will naturally thrive in well-draining soil.

You can tell how well-draining potting soil is if you have grown these plants. Otherwise, you could tell it by simply doing a small test.

Water your pot containing regular potting mix thoroughly, then water it again. If the water puddles up, it is slow draining; if all the water drains out, it is fast draining.

You would want the potting soil that drains 2.5 cm per hour to ensure well-draining soil. Here is a small table for soil drainage capacity.

CapacityDrainage per hour
Slow-drainingLess than 2 inch
Well-draining2 to 3 inch
Fast-draining4 inches or more

Note: One of the best well-draining soils is the orchid mix which provides the correct soil drainage, structural support, and moisture retention.

How to Make Well-Draining Potting Soil?

If you are an avid gardener, you would love to make potting soil at home by sourcing suitable materials.

Organic matter like peat, coco, and compost provide healthy microorganisms, while inorganic materials like perlite and vermiculite promote aeration by making the soil porous.

How to Make Potting Soil Well-Draining?

Consider amending the potting soil with a different matter if you have already prepared a substrate, but it is not so well-draining.

  • In the case of potting soil rich in sand and clay, add 1/3 parts perlite or orchid bark to make the substrate lighter.
  • For compact potting soil, consider mixing it with organic compost, pine bark, composted leaves, and vermiculite.
  • Add sand, peat moss, and orchid bark for loose soil to provide more support and a denser structure.
  • Similarly, mixing the loose soil with organic compost will help add the missing nutrients and provide volume.
  • Remember to add some organic compost and perlite or vermiculite when using last year’s soil to provide missing nutrients and prevent compaction.
  • Adding peat moss or clay to an existing low-draining soil will worsen it.
  • Similarly, adding a significant amount of perlite or pine bark will loosen the soil’s structure.
  • When amending the last year’s soil, you can either remove half of it or push it to the bottom of the pot and fill the upper part with a fresh mix.
  • Do not forget to check the soil pH level before planting to ensure the soil condition is correct for the particular plant.
