Design Considerations
When selecting a large concrete bowl planter, you need to consider the key factors that will ensure your planter not only fits the space intended but also remains functional and durable over time.
Size and Proportions
Your planter’s size should complement the space without overwhelming it. For a balanced look, ensure the diameter of the bowl is in proportion with the area’s width and that its height doesn’t obstruct key sightlines. For example, U Bowls by Quatro Design come in various heights, such as 500, 700, and 900mm, allowing for versatility in design. You can mix and match these sizes for an elegant cluster effect.
Drainage Requirements
Proper drainage is crucial to prevent waterlogging and root rot. Make sure your concrete bowl planter has adequate drainage holes at the bottom. If positioning your planter on a non-absorbent surface, consider elevating it to facilitate water flow. Additionally, incorporating a layer of gravel before adding soil can enhance drainage efficiency.
Material Selection
Opt for Glassfibre Reinforced Concrete (GRC) to strike a balance between strength and weight. GRC is a composite of concrete and fibreglass, which offers durability without the heavy weight of traditional concrete, making it ideal for larger planters such as the sophisticated designs available from Quatro Design. Furthermore, this material can endure harsh weather conditions, which is essential in Australia’s varied climates.
Construction Guide
Crafting a large concrete bowl planter involves precise steps that ensure the final product is both visually appealing and structurally sound. Starting with a reliable mould, mixing the correct concrete consistency, and following a thorough curing process are all essential to achieving a high-quality planter.
Creating the Mould
For your planter, it’s important to select two sturdy containers as moulds; one larger for the outer shape and a smaller one to form the inner cavity. Coat the inside of the larger container and the outside of the smaller with non-stick cooking spray to ensure easy removal after the concrete sets. Stability can be enhanced by attaching weights or wooden braces to keep the smaller container centred during the casting process.
Mixing the Concrete
You’ll need a strong, weather-resistant concrete mix, suitable for outdoor use. Mix the concrete in a large tub or wheelbarrow to a thick, creamy consistency, similar to a well-blended milkshake. If the mix is too runny, add more concrete powder; if it’s too dry and crumbly, introduce water sparingly until the desired consistency is achieved.
Casting Process
Pour the mixed concrete into the larger mould until it’s about halfway full. Carefully place the smaller container inside, pressing down until it reaches the middle of the concrete mix. Fill the edges with more concrete, and tap the sides gently to remove air bubbles. Maintain an even thickness around the edges for a uniform look and structural integrity.
Curing and Removal
After filling, cover the mould with plastic to prevent rapid moisture loss and allow it to cure for a minimum of 48 hours. Longer curing times can result in a stronger planter. When the concrete has hardened sufficiently, remove the weights and braces, and carefully extract the inner mould. Turn the larger container upside down and gently tap it to release your new concrete bowl planter.
Finishing Touches
When you’ve chosen a large concrete bowl planter for your space, the right finishing touches can transform it from a simple container to a standout feature in your home or garden.
Sealing the Concrete
To ensure your concrete bowl planter stands the test of time, sealing is crucial. Sealing the concrete prevents water penetration, stains, and weather-related damage. Begin by ensuring the planter is completely dry. Apply a sealant specifically designed for concrete, like a water-based sealer, which is eco-friendly and less toxic. Usually, two coats are recommended, with adequate drying time between applications.
Decorative Techniques
After sealing, you might consider adding a personal touch with decorative techniques:
- Stain or Paint: Add color to your planter using concrete stains or paints, selecting hues that complement your outdoor palette.
- Texturize: Create a rough, rustic look with a textured spray or by applying a second layer of concrete mixed with pebbles or sand.
- Mosaics or Decals: For an artistic flair, affix tiles in a mosaic pattern or use outdoor decals to tell a story on your planter’s surface.
Remember to select weather-resistant decorations to maintain the appearance despite the elements.
Placement and Landscaping
Choosing the ideal spot for your large concrete bowl planter and integrating it into your garden can drastically enhance your outdoor space’s aesthetic and functionality.
Choosing the Right Location
To ensure your large concrete bowl planter thrives, consider sunlight exposure and drainage needs. Heavy planters are best placed on solid grounds like concrete slabs or compacted gravel to avoid sinking. Visibility is key – pick a spot that’s visible from indoor spaces or seating areas.
Incorporating into Garden Design
When weaving the planter into your garden’s design, aim for balance and proportion. For symmetry, place your planter in line with other garden features. Opt for plants that complement your garden’s colour scheme and vary in height for dynamic visuals. Use trailing plants to soften the concrete’s appearance and create a lush, overflowing look.
Maintenance Tips
Maintaining your large concrete bowl planter is straightforward if you stay on top of the care routine. Regular upkeep will keep it looking pristine and extend its lifespan.
Regular Cleaning
To prevent build-up of dirt and grime, give your planter a gentle clean every couple of months. Start with a soft brush or cloth to sweep away loose debris, then wash with a mild soap solution, and rinse thoroughly with water. Ensure to avoid abrasive cleaners which could damage the concrete surface.
Winter Care
Concrete is durable but can be susceptible to frost. In colder months, protect your planter by raising it off the ground with pot feet to prevent water logging, which can lead to cracking when temperatures drop. It’s also wise to wrap your planter in hessian or bubble wrap if expecting severe frosts.
Repairing Cracks
If you notice small cracks, you can repair them promptly to prevent further damage. Clean the affected area first, then apply a concrete filler matching your planter’s colour. Allow it to dry completely before lightly sanding to achieve a smooth finish.
