Mixed soil vs loam soil is a question Filipino gardeners ask when shopping for container growing media. Mixed soil is a custom blend of several ingredients designed for potted plants. Loam soil is a natural soil type with a balanced texture. Both work for gardening, but they differ in consistency, nutrients, and price.
What Is Mixed Soil?
Mixed soil is a blend of two or more growing media combined to create an all-purpose potting medium. In the Philippines, a typical mixed soil contains loam soil, garden soil, coco peat, compost, and rice hull. Suppliers mix these ingredients to improve drainage, moisture retention, and nutrient content beyond what any single soil type offers. The quality of mixed soil varies widely between sellers. Some use carefully measured ratios while others just combine whatever is available. Always check the texture and smell before buying in bulk.
What Is Loam Soil?
Loam soil is a natural soil type containing roughly 40 percent sand, 40 percent silt, and 20 percent clay. This balanced ratio gives loam its signature crumbly feel and excellent drainage properties. Loam holds enough moisture for roots to drink from while letting excess water flow through. It is the most commonly sold soil type at garden centres across Metro Manila. Screened loam soil has been filtered to remove rocks, roots, and debris. It works straight out of the bag for most container plants.
Mixed Soil vs Loam Soil: Key Differences
The main difference is that mixed soil is a manufactured blend while loam soil is a single, natural product. This affects everything from nutrient content to consistency between batches. Here is a detailed comparison.
| Criteria | Mixed Soil | Loam Soil |
|---|---|---|
| Composition | Multi-ingredient blend | Natural sand-silt-clay mix |
| Nutrients | Higher (compost added) | Moderate |
| Drainage | Good to excellent | Excellent |
| Consistency | Varies by supplier | Consistent texture |
| Best use | Ready-to-plant containers | Base medium for custom mixes |
| Price (PH market) | P100 to P200 per sack | P75 to P150 per sack |
When to Use Mixed Soil
Choose mixed soil when you want a ready-to-use medium that does not need extra amendments. It saves time because the blend already includes organic matter and drainage materials. Mixed soil works well for beginner gardeners planting vegetables, herbs, and ornamentals in pots. Look for suppliers who list their exact ingredients and ratios. A good mixed soil should feel light and crumbly, not heavy or sticky. For the best results, pair it with regular organic fertiliser applications every two to three weeks.
When to Use Loam Soil
Use loam soil when you want a reliable base that you can customise for different plants. Buy screened loam soil and add your own coco peat, compost, or perlite in ratios that suit your specific plants. This gives you full control over the growing medium. Loam soil also works well for raised bed gardens where you need large volumes at a lower cost per sack. Many experienced Filipino gardeners prefer buying pure loam and mixing it themselves rather than trusting pre-mixed blends of unknown quality.
Which Should You Choose?
If you are a beginner and want convenience, buy mixed soil from a trusted supplier. It gets you planting faster without the need to source and measure individual ingredients. If you want consistency and control, start with loam soil and build your own mix. You will save money on large projects and know exactly what goes into every pot. For a simple DIY mix, combine 50 percent loam soil, 30 percent coco peat, and 20 percent compost. Check our plant guide for species-specific soil recommendations.

Frequently Asked Questions
What is mixed soil made of in the Philippines?
Mixed soil in the Philippines typically contains loam soil, garden soil, coco peat, compost, and sometimes rice hull or carbonised rice hull. The exact ratio varies by supplier and intended use. A common mix for container gardening is 40 percent loam soil, 30 percent garden soil, 20 percent coco peat, and 10 percent compost. Some sellers add vermicast or perlite for extra nutrients and drainage. Unlike standardised potting mixes from international brands, Filipino mixed soil blends vary from one supplier to another. Always ask your supplier what ingredients they use so you know what your plants are growing in.
Is mixed soil better than pure loam soil for potted plants?
Mixed soil is generally better than pure loam soil for potted plants because it combines the strengths of multiple ingredients. Pure loam soil can compact over time in containers, reducing air flow to roots. A good mixed soil adds coco peat for moisture retention and compost for nutrients, solving the problems that pure loam has in pots. However, the quality of mixed soil depends entirely on the supplier. A poorly mixed batch with too much clay or not enough organic matter can perform worse than pure loam. If you buy mixed soil, check the texture before filling your pots. It should feel crumbly and light, not heavy or sticky.
Can I make my own mixed soil at home?
Yes, making your own mixed soil at home is straightforward and often gives better results than store-bought blends. Start with screened loam soil as your base at 40 to 50 percent of the total volume. Add 20 to 30 percent coco peat for moisture retention. Mix in 10 to 20 percent compost or vermicast for nutrients. Finish with 10 percent perlite or carbonised rice hull for drainage. Combine everything in a large basin or on a tarp and mix thoroughly. This DIY approach lets you adjust the ratio for specific plants. Use more coco peat for moisture-loving ferns and more perlite for succulents that need fast drainage.
