Warranty?
We proudly offer a 3-year warranty on all our planters to ensure you enjoy years of beauty and functionality. You can extend this warranty to 5 years at checkout.
This warranty covers manufacturing defects that affect the structural integrity of your planter.
What’s Not Covered:
• Normal wear and tear: Fading and hairline cracks are natural occurrences over time and are not covered by the warranty.
• Improper care: Damage caused by improper handling or use, such as blistering paint from leaving packaging on for more than 7 days, will void the warranty.
• Modifications: Our planters are designed for stability on flat surfaces. Adding large, external feet that don’t provide full base support can cause bowing and void the warranty.
• Misuse: This warranty applies to planters used for their intended purpose – growing plants. Using them as water features is not covered.

Custom Painted Trough Planters
The Jakarta Light Grey Fibreglass Trough is essentially the same as the Manhattan range of outdoor plant pots. However, by using the light grey undercoat only, we’re able to offer a slightly lower price.
This makes the planters perfect for custom painting or can be used as-is. The light grey hue provides a subtle backdrop for your plants, creating a refined and understated look.
The paint remains durable and suitable for all weather conditions, and the light grey colour is naturally UV-resistant for planting pots.

The Moscow charcoal planter box presents my home entrance well. I have several products in this brand I purchased 3 years ago and the colour has not changed. They are still stunning and as new. I highly recommend them.

Learn More About Our Large Planters
Do You Need A Large Planter?
Basically, Big Plants Need Big Homes. There’s no strict rulebook for defining a large planter. Generally speaking, it’s any container that requires a two-handed lift. We’re talking dimensions that can range from a modest 60 centimetres to an impressive 200 centimetres or beyond.
Why size matters:
Rooted in Success: Big plants have big root systems. Large planters provide the essential space for these root structures to thrive. Without ample room, your greenery can become stunted, stressed, and even decline.
Community Living: If you’re planning a plant community, a larger planter ensures everyone gets their fair share of soil. This prevents overcrowding and promotes healthy growth.
In short, if your plants are large you need large planters. A large planter can be the perfect foundation for your green ambitions.
Why Buy Large Planters?
Safety and Stability: Large planters are essential for anchoring plants like trees. Their weight and size provide crucial stability, protecting both the plant and people.
Functional Design: Beyond safety, large planters are versatile design elements. Use them to create private zones within open spaces, guide foot traffic, or conceal less attractive areas. They’re modern alternatives to traditional dividers, adding a touch of nature and elegance.
Style and Impact: Large planters are bold statements that can transform a space. Whether it’s a striking centrepiece or a subtle complement, they add a touch of sophistication. They can breathe new life into dull areas and elevate the overall aesthetic of your interior or exterior.
In essence, large planters offer more than just a place to grow plants. They are functional, stylish, and capable of dramatically enhancing your space.

Enhancing Urban Spaces: Large Planter Design in Professional Landscape Architecture
Built-In Feet Included: Elevated Design. No Drainage Issues
All planters come with feet built into the base of the planter to assist with drainage and stay mess free.
Waterproof: Internally Sealed for Effortless Planting
All planters are internally sealed with a water proof polyurethane resin. Just add premium quality potting mix and plants.
Pre-Drilled Drainage Holes: Reinforced for Additional Strength
All planters have drainage holes approx 25-35mm in diameter. These are reinforced to offer maximum durabilty and longevity.
