What Is A Good Depth For A Raised Garden Bed?

The ideal depth of a raised garden bed depends on what type of plants you are growing. In general, most vegetables, fruits, and herbs do best with at least 8in. of soil depth. However, if you have drainage issues or are growing plants that are sensitive to excess moisture around their roots, additional depth can help by allowing water to seep naturally.



That’s why selecting a planter box that is 12in. deep is perfect for your raised garden bed needs! This ensures the roots have enough room to spread out properly and access all the nutrients they need to grow healthy. With this depth, you can also support larger vegetables like tomatoes and squash.



If you plan on growing smaller plants, such as strawberries, herbs, or flowers, then a 12-inch deep planter box will be plenty of space for your gardening needs.

Are Galvanized Steel GardenBeds Safe?

Yes, galvanized steel beds are safe for use in your vegetable garden! Since most garden soils have a neutral pH, the acidity needed to break down the zinc is not present. Furthermore, zinc is an essential micronutrient for plants and can be beneficial when present in small amounts. All in all, galvanized steel beds are an excellent option for both their longevity and safety.


Still on the fence if they are safe? Just add a liner to your planter box for extra protection and peace of mind. This will help prevent contact between the soil and the steel, while also preventing corrosion.

Benefits of Galvanized Raised Garden Beds



Galvanized steel raised garden beds are much lighter weight than other materials like wood or stone, making them incredibly easy to move around. This means you can set up your garden bed without breaking a sweat and with minimal effort.



Plus, if you ever need to rearrange your garden beds later on down the road, you can remove the soil and just pick the entire planter box up and move it. Warning, this process takes maximum effort and you might break a sweat.



Rust Resistant


We know galvanized metal for its superior rust resistance properties. This is due to the zinc coating, which provides a barrier that is extremely weather resistant when exposed to outdoor elements like rain or wind. As a result, galvanized raised garden beds are highly durable and can last up to 20 years with minimal maintenance.



Aesthetic Appeal


Galvanized steel raised garden beds bring a unique and modern look to any outdoor space. Their sleek design adds an unexpected touch of elegance to your garden and can easily become the focal point of your backyard.



Plus, you won’t have to worry about them clashing with other elements in your yard as they come in a variety of colors to suit any aesthetic. So no matter your style, there’s a galvanized steel raised garden bed that will be the perfect fit for your space.





Midnight grey, yellow, cobalt blue? Galvanized steel planter boxes are easy to customize with paint to create a look that is truly unique and one-of-a-kind. Painting your planter box can turn it from an ordinary garden staple into a stunning feature in your outdoor space.
