How to Ensure Ideal Pilea Potting Soil?
The Pilea plant is picky about the growing medium because it naturally grows on limestone boulders in mountainous forests.
However, it has come far from its natural setting to a typical house where it can survive well in standard potting soil.
Before we start preparing the potting soil for Pilea, let us look at how to ensure an ideal potting soil.
1. Soil Moisture
Pilea plant prefers a slight drought rather than sitting in water.
When the soil is too soggy, the roots will drown in water, leading to oxidation, decay, and fungus infestation.
Therefore, the key is maintaining correct soil moisture to optimize oxygen, water, and nutrient intake from soil to stem and leaves via roots.
Ensure to water Pilea only when the top 2-3 inches of topsoil dries out.
It would sum up to every 1-2 weeks in spring and summer and 20-25 days in fall and winter when the plant hibernates.
2. Drainage Capacity of Soil
The Pilea plant requires a well-draining potting soil that remains loamy but soggy.
The water should naturally drain out at 1-2 inches per hour to ensure the roots get enough moisture without staying wet for a prolonged duration.
The Pilea plant may also survive in fast-draining soil until you can water the plant regularly, twice weekly.
Another primary consideration for better drainage is the choice of pot. Choose clay or terracotta pots that repel excess moisture, keeping the root dry and healthy.
When choosing a plastic or ceramic pot, ensure it has multiple drainage holes at the bottom.
3. Nutrients and Organic Matter
Pilea naturally takes up significant water and dissolved nutrients through root hairs, which are later passed through the stem toward leaves.
However, be wary about the type of fertilizer and how often to use it to prevent salt buildup in the soil of Pilea.
So, try maintaining the fertilizer intake to once a month in the growing season and only apply a balanced fertilizer diluted to ¼ strength.
In addition, only use organic and certified fertilizer for the Pilea plant to boost healthy microorganisms in the soil.
4. Warm Soil Temperature
The warm growing medium assists photosynthesis and promotes optimal humidity around the Pilea to keep it thriving and green.
The ideal temperature of 55°F-85°F with at least 70°F during the day will ensure a healthy-looking plant.
Moreover, move them inside in fall and winter when the temperature drops significantly.
5. Slightly Acidic Nature
A pan-tropical species, Pilea thrives in slightly acidic soil that helps easily absorb readily available nutrients rather than in alkaline soil.
High pH or alkaline soil releases sodium into the soil, slowing the root growth of tropical plants.
One way to obtain naturally acidic soil is using organic materials in the potting mix.
Otherwise, mix some crushed sulfur or ammonium-based nitrogen when amending the potting mix to decrease its pH level.
Note: Beware of low pH toxicity on the plant, which may lead to aluminum and manganese poisoning, risking poor root growth.
Preparing the Soil/Potting Mix for Pilea
Pilea plant requires a well-draining, organic, and loamy potting mix based mainly on peat moss, coco coir, and perlite.

Problems due to Poor Soil Condition in Pilea Plant
Wrong potting soil and poor soil condition are two significant factors that may cause a sick-looking Pilea Peperomioides.
1. Yellowing or Drooping Leaves: The early indication of soil problems is when the leaves turn yellow and droop due to soggy conditions and mold or pest infestation.
- Solution: Cut back on watering, check for root rot, and prune away the damaged roots before applying fungicide to prevent fungal infestation.
2. Soil Compaction: Overfertilization and overwatering the plant often leads to compact soil where excess watering flushes out needed aerating materials, and synthetic fertilizer may kill healthy microorganisms.
- Solution: The best solution is transplanting your Pilea in a fresh potting mix.
3. Curling Leaves: The potting mix, either too old or lacking regular fertilization, will exhibit curling and discolored leaves.
- Solution: Introduce monthly plant fertilization with balanced organic liquid food to increase the number of healthy microbes in the soil.
4. Stunted Growth: Using the wrong potting mix or lacking nutrients and healthy soil microbes will lead to stunted growth.
- Solution: Begin fertilizing your plant, aerate the soil with organic compost or replace the potting mix.
5. Soil Contamination: Using synthetic fertilizer, applying undiluted fertilizer, or excess fertilization may lead to salt buildup in the soil, root and stem burn, yellowing foliage etc.
- Solution: Your only solution is to replace the potting soil with a fresh mix.
Does Pilea Need Fertilizer along the Soil mix?
It is a good idea to regularly fertilize your Pilea plant to enrich the soil with the required nutrients to strengthen foliage growth and maintain the lush green color.
And better to feed the Pilea when watering to encourage the roots to get the most nutrients before they begin flushing.
Signs your Pilea Needs Fertilizing
The Pilea plant will begin exhibiting some visible signs due to a lack of nutrients, including;
- The yellowing of tips with gradual yellowing of the entire leaf and stem is usually caused by nitrogen deficiency.
- The dull appearance of the foliage is due to potassium deficiency.
- A lack of potassium leaves small patches of discoloration.
- Slowed growth in the growing season.
- Purple or reddish color on the leaves due to chlorosis.
On the other hand, overfertilization will show vivid signs, including drooping leaves, stunted growth, stem decay, and discolored soil.

FAQs About Pilea Soil and Fertilizer
What kind of soil do Pilea need?
Choose a well-draining potting mix rich in organic matter instead of the regular and cheap potting soil used for other houseplants.
Also, although they have succulent leaves, better not to choose a succulent soil with high perlite and sand quantity as it allows quick percolation of water.
What kind of fertilizer does a Pilea need?
Pilea is a light feeder, befitting from the monthly supply of balanced liquid fertilizer diluted to 1/4th of its strength.
You can also choose homemade and organic fertilizers rich in nitrogen and potassium content to maintain the health of Pilea.
Is coffee good for Pilea?
Coffee grounds help to make the soil more acidic by decreasing the alkalinity of the soil. And we know that Pilea loves slightly acidic soil.
So adding coffee grounds will help in the nutrient uptake from the soil.
Final Thought
Most of the Pilea novices are more likely to make mistakes with the potting soil and regular care than seasoned gardeners.
Remember to use the correct soil mix and provide ample indirect sunlight, humidity, and organic fertilizer to witness a healthy Pilea plant.
Pay special attention to the watering schedule and the type of fertilizer you use.
