Clay Pots (Terracotta)
Clay pots vs plastic pots for plants is a debate that every Filipino gardener encounters at the garden shop. Clay pots (terracotta) are made from fired natural clay. They have been used for growing plants for thousands of years and remain popular for good reason.
The porous walls of clay pots allow air and water to pass through, which keeps roots healthy and prevents overwatering. This breathability makes clay ideal for plants that hate sitting in wet soil. The natural terracotta colour also gives gardens a classic, warm aesthetic.
However, clay pots are heavier, more fragile, and more expensive than plastic. They crack in extreme heat, break when dropped, and dry out soil faster in the Philippine summer. Large clay pots can be very heavy once filled with moist soil.
Plastic Pots
Plastic pots are lightweight, affordable, and available in every size, colour, and style imaginable. They retain moisture longer than clay because the non-porous walls prevent evaporation through the sides.
Modern plastic pots are made from UV-stabilised materials that resist sun damage. Quality garden-grade plastic lasts 3 to 5 years outdoors in the Philippine climate. They are easy to move, stack, and clean. For balcony and rooftop gardens where weight matters, plastic is the practical choice.
The downside is that plastic does not breathe. Roots in plastic pots can suffocate or rot if you overwater. Cheap plastic also degrades in direct sun and can leach chemicals into soil over time. Always choose food-grade or garden-grade plastic for edible crops.
Key Differences: Clay Pots vs Plastic Pots
| Criteria | Clay Pots | Plastic Pots |
|---|---|---|
| Drainage | Excellent (porous walls + hole) | Good (drainage hole only) |
| Weight | Heavy | Lightweight |
| Cost | P50 to P500 (medium) | P15 to P200 (medium) |
| Durability | Fragile (cracks, breaks) | Durable (flexible) |
| Moisture Retention | Low (dries fast) | High (stays moist longer) |
| Root Health | Excellent (air pruning) | Good (needs proper drainage) |
| Aesthetics | Natural, classic look | Many colours and styles |
| Heat Absorption | High (heats up in sun) | Moderate (lighter colours reflect) |
| Best For | Succulents, herbs, orchids | Tropicals, ferns, vegetables |
| Lifespan | Years (if not cracked) | 3 to 5 years outdoors |
When to Use Clay Pots
- You grow succulents, cacti, or plants that need dry soil between waterings
- You tend to overwater and need pots that self-correct excess moisture
- You want a natural, rustic look for your garden display
- Your pots sit in a sheltered area protected from falls and extreme sun
- You grow herbs that produce better flavour in well-drained, drier soil

When to Use Plastic Pots
- You garden on a balcony or rooftop where weight is a concern
- You grow moisture-loving tropicals and ferns that need consistent hydration
- You have children or pets who might knock pots over
- You need affordable containers for a large container garden
- You move pots frequently to follow sunlight or avoid storms
Which Should You Choose?
Use clay pots for drought-tolerant plants and display pieces. Use plastic for everyday vegetable growing, rooftop gardens, and any situation where weight and cost matter. Many Filipino gardeners use both: clay for herbs and succulents on the front porch, plastic for vegetables and tropicals in the productive garden area.
Regardless of pot material, always ensure drainage holes at the bottom and use quality loam soil mixed with compost and rice hull for the best results. Read our raised bed vs container guide for more growing setup options.
Frequently Asked Questions
Are clay pots better than plastic pots for plants?
Clay pots are better for plants that need excellent drainage and airflow around roots, such as succulents, cacti, herbs, and orchids. The porous material wicks moisture away from roots and prevents overwatering. Plastic pots retain moisture longer and work better for tropical plants, ferns, and leafy vegetables that prefer consistently moist soil. Neither is universally better. The right choice depends on the plant species and your watering habits.
Why do clay pots crack in the Philippines?
Clay pots crack in the Philippines primarily from extreme temperature changes and salt buildup. During the dry season, intense sun heats the pot while sudden rain cools it rapidly, causing thermal shock. Mineral deposits from fertiliser and hard water also weaken the clay over time. To prevent cracking, keep clay pots in partial shade during peak summer heat, water gently rather than shocking them with cold water, and scrub off salt deposits regularly.
Do plastic pots have enough drainage for plants?
Most plastic pots have drainage holes at the bottom, which provides adequate drainage for most plants. However, unlike clay pots, plastic does not absorb or evaporate water through its walls. This means soil stays wetter for longer in plastic containers. To improve drainage, add a 2 to 3 centimetre layer of pebbles or broken clay pieces at the bottom and use a well-draining soil mix with 10% perlite or rice hull.
