Why Choose Aluminum and Corten Steel Planters?

Aluminum and corten steel are excellent choices for outdoor planters. Here's why:



These metal planters can handle different weather conditions. They won't crack or break easily. Aluminum planters are very light, which is great for rooftops. Corten steel planters have a unique look that many people like. Both types resist rust, so they last a long time. Check out our aluminum and corten steel planter options.


Making the Most of Your Space

Modular planters are great for small spaces. You can arrange them in different ways to fit your rooftop. Some planters can stack on top of each other. Others can connect side by side. This means you can create a garden that fits your space perfectly. You can even use them for vertical gardening, growing plants up walls or trellises. Get ideas for your rooftop garden design.


The flexibility of modular planters allows you to create unique layouts that maximize your available space. You can create different levels, separate areas for various plants, or even use them to divide your rooftop into distinct zones. This adaptability is particularly valuable in urban settings where space is at a premium.



Aluminum Planters: Light and Strong

Aluminum planters are perfect for rooftop gardens. They're very light, so they won't put too much weight on your roof. This is important for safety. Aluminum also doesn't rust, even in rainy or humid weather. You can get aluminum planters in many colors and finishes. This means you can match them to your style or building design.


The versatility of aluminum planters extends beyond their weight and durability. They're also excellent at regulating soil temperature, which can be beneficial for plant health. Aluminum's ability to reflect sunlight helps prevent soil from overheating in hot weather, protecting delicate root systems. Additionally, these planters can be easily customized with paint or other finishes, allowing you to refresh your garden's look whenever you want.


Corten Steel Planters: Rustic and Tough

Corten steel planters have a special look. When they're new, they're a regular steel color. But over time, they develop a rusty orange color. This is called a patina. It looks great and protects the planter. Corten steel is very strong, so it's good for bigger plants. These planters don't need much care, which is great for busy people.


The unique aging process of corten steel adds character to your rooftop garden. As the patina develops, each planter becomes a one-of-a-kind piece, adding depth and texture to your outdoor space. This natural weathering process also means that corten steel planters blend well with a variety of architectural styles, from modern to industrial to rustic. Their strength makes them ideal for trees or large shrubs that require deep soil and substantial support.


Planning Your Rooftop Garden

When you're planning your rooftop garden, think about these things:

  • How much space do you have?

  • What shapes and sizes of planters will fit best?

  • Do you want different areas for different types of plants?

  • How much sunlight does your rooftop receive?

  • Are there any weight restrictions you need to consider?

  • What's your budget for planters and plants?


You can mix and match planter sizes to create an interesting layout. Some people like to create separate areas for vegetables, flowers, and seating. Learn about our custom planter options for unique designs.



Setting Up Your Planters Safely

Before you start your garden, make sure your roof can hold the weight. Here are some important steps:

  1. Check how much weight your roof can hold

  2. Make sure your planters have good drainage

  3. Secure your planters so they don't blow away in strong winds

  4. Consider using a protective layer between the planters and your roof surface

  5. Plan for easy access to water sources

  6. Ensure there's proper ventilation around your plants


It's a good idea to talk to an expert if you're not sure about any of these steps. Safety is very important when you're creating a rooftop garden.


Taking Care of Your Metal Planters

Metal planters are easy to care for, but they do need some attention. Here's what to do:

  • Clean aluminum planters with soap and water

  • Let corten steel develop its natural patina

  • Protect your planters in very cold weather

  • Check for and address any drainage issues promptly

  • Inspect for any signs of damage or wear annually

  • Apply a protective coating to aluminum planters if desired


In winter, you might need to move your planters to a sheltered spot or cover them. This helps protect both the planters and the plants inside them. For corten steel planters, ensure that the drainage holes remain clear as the patina develops to prevent water accumulation.


Choosing Plants for Metal Planters

Not all plants grow well in metal planters. Here are some tips:

  • Choose plants that can handle heat, as metal can get hot in the sun

  • Use good soil that holds moisture well

  • Try planting different types of plants together

  • Consider drought-resistant plants to reduce watering needs

  • Use plants with shallow root systems for shallower planters

  • Include some trailing plants to soften the edges of your planters


Herbs, succulents, and many vegetables grow well in metal planters. You can also grow flowers for color and to attract bees and butterflies. Consider creating a mix of ornamental and edible plants to make your rooftop garden both beautiful and functional.
