If you’re looking to take your pothos plants from “surviving” to thriving, the secret might be in the soil! While pothos are famously low-maintenance and can grow in almost any condition, they’ll be at their healthiest and most vibrant when planted in the right kind of soil. By adding a few key ingredients to your potting mix, you can create the ideal environment for your pothos to grow lush, green, and strong.
In this article, we’ll break down the specific soil additions that help pothos reach their full potential. From drainage-boosting ingredients to nutrient-rich additions, these tips will give your pothos the extra support they need to grow like never before.
So, let’s dive in and get your pothos the soil it deserves!
What To Add To Pothos Soil So They Thrive!
How to better your pothos plant’s soil:
1. Good Quality Potting Soil as a Base
Start with a high-quality potting mix. A general-purpose indoor plant potting mix works well, as it provides the basic nutrients pothos needs. Look for soil that’s well-draining but can hold enough moisture to keep your pothos happy between waterings. You want the soil to be loose and airy, so the roots have room to breathe.
Tip: Avoid heavy garden soil or soil from your yard. Pothos needs soil that won’t compact, as compacted soil restricts root growth and airflow.
2. Perlite for Drainage
Adding perlite to the mix helps with drainage, which is essential for pothos. These plants love moisture but don’t do well with soggy roots. Perlite is a lightweight, white volcanic rock that helps aerate the soil while preventing excess moisture from building up. Just mix in about 10-20% perlite with your potting soil to keep things airy and well-drained.
Alternative: If you can’t find perlite, pumice or coarse sand will also work, as they serve the same purpose by keeping the soil loose and preventing water from pooling.
3. Coconut Coir or Peat Moss for Moisture Retention
Coconut coir or peat moss helps the soil retain moisture without becoming waterlogged. These additions act like sponges, soaking up water and releasing it slowly, which can keep your pothos roots happy. Add about 10-15% coconut coir or peat moss to the mix. Coconut coir is the eco-friendlier option since it’s renewable, whereas peat moss is harvested from non-renewable peat bogs.
Note: Coconut coir also has a neutral pH, which is perfect for pothos, as they prefer soil that’s close to neutral (around 6.0-6.5 pH).
4. Worm Castings for Natural Fertilizer
Worm castings are like a nutrient-packed superfood for plants! These castings enrich the soil with essential nutrients like nitrogen, phosphorus, and potassium, all of which are key for healthy pothos growth. They’re a natural, gentle fertilizer that won’t burn the roots, and they improve soil structure over time. Mix in about a handful or two of worm castings per pot, and you’ll have a thriving pothos with beautifully green, vibrant leaves.
Bonus: Worm castings also help ward off pests naturally, thanks to the presence of beneficial microbes that support plant health.
5. Charcoal for Root Health
Adding a small amount of horticultural charcoal can work wonders for pothos roots. Charcoal absorbs impurities and prevents harmful bacteria from building up in the soil. This is especially helpful if you occasionally overwater your pothos (hey, it happens!). Charcoal also helps regulate moisture levels in the soil, keeping the roots healthy. Just add a small layer at the bottom of the pot or mix a pinch into the soil blend.
Note: Horticultural charcoal (sometimes labeled as activated charcoal) is the type to use, as it’s designed specifically for plants.
6. Compost for Extra Nutrients
Compost is packed with beneficial microbes and organic material that can boost the nutrient content of your pothos soil. It’s a great way to add slow-releasing nutrients to the mix. You don’t need a lot—just mix a little compost (about 10% of the soil mixture) to improve soil fertility and feed your pothos gradually over time.
Pro Tip: Make sure the compost is well-rotted and mature, as fresh compost can be too strong and might damage sensitive roots.
7. A Touch of Sand for Extra Drainage
While not essential, adding a little coarse sand to the soil can improve drainage for pothos, especially in humid environments where soil tends to stay damp for longer. Sand helps keep the soil structure loose and aids in water flow, preventing root rot. Just a small amount, mixed with perlite or pumice, can make a big difference in keeping the soil airy.
Now let’s talk about the actual recipe and mixing the soil before you pot or repot your pothos plant!
How to Mix Your Perfect Pothos Soil
Here’s a simple recipe to get you started:
- 60% High-quality potting mix
- 10-15% Perlite for aeration
- 10% Coconut coir or peat moss for moisture retention
- 10% Compost or worm castings for nutrients
- 5% Charcoal to prevent bacteria and absorb excess moisture
Combine all ingredients well, and add a little sand if you want even more drainage support. This mix will provide everything your pothos needs for robust growth, healthy roots, and lush, green foliage.
A Few Extra Tips for Thriving Pothos Plants
- Water Carefully – Pothos are forgiving, but overwatering is one of the few things that can make them unhappy. Let the top inch of soil dry out before watering again, and always use a pot with drainage holes.
- Rotate Your Plant – Pothos tend to lean toward the light source, so rotating your pot every few weeks will keep growth balanced and prevent the plant from becoming lopsided.
- Fertilize Occasionally – In addition to the worm castings or compost in the soil, consider using a balanced liquid fertilizer once a month during the growing season to give your pothos an extra boost.
- Prune and Propagate – Pruning keeps pothos looking full and encourages new growth. You can also propagate any cuttings in water and start new plants from them!
With these soil tips and a little TLC, your pothos will thrive and become a beautiful, low-maintenance star in your indoor garden. A well-prepared soil mix sets the stage for healthy growth, lush foliage, and a happy plant that will keep growing for years to come! Happy planting!
