Why We Love It

Makes Starting a Garden Simple: It helps your soil. It reduces pest problems. It’s built to last. Whether you’re a beginner or a longtime green thumb, our metal raised beds are a no-hassle way to get started and keep growing with square foot dimensions that make planning your garden easy.

Good for the Planet: Sustainably made in Australia using renewable energy, ethical labor, and recycling practices.

Versatility: It’s the perfect starting point for whatever garden you’re imagining and can be made into five different shapes to hold everything from fresh veggies and herb patches to butterfly gardens.

7x More Corrosion- & Rust-Resistant Than Standard Metal Beds: Our 24-gauge, cold-rolled aluzinc steel is 7x more corrosion- and rust-resistant than the galvanized steel most beds use. No need to worry about it breaking down or needing to be replaced. This bed is built to last for decades of harvests.

100% Food-Safe Materials: We’re here to help your garden grow right. Ensuring you have safe and healthy soil for food production is priority number one.

Exclusive Epic Gardening Design: These beds were created by real gardeners. We designed and tested the beds for years before bringing them to you. (We still have the original prototype beds from 2007 that show minimal signs of rust and corrosion.) We trust them in our own gardens, so you know they get the job done right.

FAQ

Q: Can I place the beds on hard surfaces such as concrete?

A: If you're placing your bed on pavers, concrete, tiles, a porch, or anything you don't want to stain, it’s better to add a bed liner or geotextile fabric. Go ahead and place your box in position, then put the fabric on the bottom of the bed from the inside. Run any excess fabric up each side and then fill your bed with soil. The fabric allows water to drain freely, but it keeps soil from messing up your floor. Optional: To really protect the surface, place thick builder's plastic down before putting your bed into position. Once the bed is filled, any excess plastic can be trimmed around the edge of the garden bed with an Exacto knife.

Q: Can I combine beds?

A: Yes, you can combine two beds together. We always recommend installing bracing bars when combining beds to prevent bowing due to soil pressure. For detailed instructions, check out growepic.co/bracinginfo.

Q: What are the benefits of raised bed gardening?

A: Raised bed gardening reduces pest pressures, elevates the garden to a more comfortable working level, and is a great way to guarantee you have quality soil to grow in. You’ll also have fewer weeds to deal with and an easier time clearing out any that pop up. Also, your soil doesn’t become compacted like an in-ground bed. It gives you better control over your gardening environment.

Q: What can I grow in my Raised Beds?

A: Pretty much anything. We’ve got some ideas to get you started, but really, the sky’s the limit.

Q: How long will these beds last?

A: All of our Birdies Beds are constructed from 24-gauge, cold-rolled steel with an aluminum-zinc (aluzinc) alloy coating. The aluzinc steel is up to 7x more rust-resistant and corrosion-resistant than standard galvanized metal. Like all iron-based metals, steel will rust eventually, but with proper care, these beds will last you 20+ years. You can improve the longevity of your beds by keeping your soil free-draining, within a 6-7 pH range, and not using fresh chicken manure.

Q: Are they safe to grow food in?

A: All the materials used are 100% food-safe and will not leach into your soil, allowing for safe, healthy food production. Our aluzinc steel raised beds are coated with a non-toxic, USDA-approved paint and the hardware supplied is food-grade stainless steel.

Q: Will the beds get too hot in summer or in hot climates?

A: No, they won’t. Compared to standard concrete and plastic beds (especially if made from a dark color or material) our metal raised beds will outperform all of them, maintaining even, cool soil temperatures. The superior

reflectivity of the aluzinc steel keeps most of the heat from ever passing into the soil. And, that bulk of soil in your bed will quickly absorb and spread the small amount of heat it gets from touching the stainless steel panels.

Q: Are the beds bottomless?

A: Yes, that means no drainage holes to drill, and the soil gets to touch the ground, so you end up with superior, microbe-rich soil and healthier plants.

Q: What is the thickness of your metal beds?

A: All Birdies Beds use 24-gauge, cold-rolled, Aluzinc-coated steel.

Q: Can the safety edging handle freezing temps?

A: Yes, the safety edging is UV-safe and designed to withstand both freezing and hot temperatures.

    Great garden boxes!

    Beautiful! Held up all summer our first summer with them, and tall enough to ward off the rabbits. Take time to build, but totally recommend!

    Large Modular Metal Raised Garden Bed Kit - 29” Extra Tall
    Easy to use once set up. Keeps small pests at bay.

    There are 5 set up here. 4 more lg to go. Working alone is slow to fill them but the results are well worth the effort. I have 1/4 in hardware cloth under them, so that and the height keep the wood chucks and rabbits out.

    (Working on the big guys solution. ) Hugel Kulture and about 18 in of bulk garden soil and compost on top half. giving excellent yields.

    With part of my back fused and both knees replaced the hight is perfect. They could not have come at a better time. I have gardened all my life and would have had to cut back without these beds.

    Hey Louis C.,

    What a fantastic review! We're absolutely thrilled to hear that your Large Modular Metal Raised Garden Bed Kits are working so well for you and that you're seeing such excellent yields from your setup!

    Your approach sounds absolutely brilliant - using that 1/4 inch hardware cloth underneath combined with the 29" height is such a smart pest management strategy! It's so satisfying when you find a solution that keeps those wood chucks and rabbits at bay. We love that you're tackling this project with 5 beds already set up and 4 more large ones to go - what an impressive garden expansion you're creating!

    The Hugelkultur method with 18 inches of bulk garden soil and compost on top sounds like the perfect growing medium setup! That combination of the deep organic matter base with quality soil on top is going to give your plants such amazing nutrition and water retention. No wonder you're getting excellent yields!

    What really touches our hearts is hearing how these raised beds have been a game-changer for continuing your lifelong passion for gardening. The 29" height being perfect for your back and knees means you can keep doing what you love without having to cut back - that's exactly what these beds are designed to do! There's something so special about finding solutions that let experienced gardeners like yourself keep growing and sharing that knowledge.

    Your experience working alone to fill them really shows the dedication, and you're so right that the results are well worth the effort!

    Thank you so much for sharing such a wonderful review about both the practical benefits and life-changing impact!

    Keep on growing 🌻️

    Easier to protect the veg!

    I live in the country surrounded by critters & varmits! They all eat vegetables. The raised beds have made it easier to fence in ( deer & chickens ) and has totally discouraged the rabbits. & ground hogs. Yay!
