Frequently Asked Questions

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.

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.

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.

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

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.

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. 

Read More: Are Galvanized Steel Garden Beds Safe?

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.

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.

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

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

    Imy wife and I love the product and are excited to finally have them assembled. However we are concerned about the paint being done at different time causing the color or finish to be off colored. However at the price we expected greater perfection.

    If you’re starting your garden don’t hesitate to get these beautiful birdie beds. I spent the same amount of money building beds out of redwood that rotted out after two years, metal beds are the way to go. Also their customer service is the best there is!
