Building Your Own Metal Raised Garden Beds

by Richard

Every gardener desires to have raised garden beds, as these “beds” bring huge benefits to their plant. Yet, metal raised garden beds are quite expensive for many people.

If you still want to own these planters without spending too much money on them, the following article will help you. Here, you can grasp the detailed steps to build your own ones and ways to maintain them.

Why Are Garden Beds Metal Raised?

Garden beds are becoming more popular than ever. Choosing materials for an equally beautiful and durable one is not easy. Don’t worry; the metal raised garden beds can’t disappoint you.

Here are a few reasons why planter boxes constructed of metal are worth considering.

Longevity

These planters are greatly influenced by soil moisture. The more humid the soil is, the heavier the soil will be, which puts a lot of pressure on the beds. Unlike wooden ones, metal ones will not rot or shrink when exposed to moisture.

Safety

The material of this type brings about an advantage in safety. Especially when you use them to grow edible plants. Harmful chemicals contained in some materials can leach into the soil, which will eventually end up showing in your food!

Metal such as galvanized steel is considered safe. The reason is that the chances of significant amounts of zinc infiltrating your soil are minor.

Cost

Though being quite expensive, metal containers are durable. You can make these yourself to save costs and bring benefits to your greens.

How To Build Your Own Metal Raised Garden Beds?

There are several ways to build metal raised garden beds. Here we will teach you how to make them with wooden frames and corrugated metal panels.

Step 1: Prepare And Cut Supplies

Prepare the materials and cut them to the correct size as follows

  • Four pieces of 2″x4″x8′ for long wooden frame
  • Four pieces of 2″x4″x4′ for short wooden frame
  • Eight pieces of 2″x4″x20″ for vertical wooden pillars
  • Two pieces of 27″x95″ for corrugated front panels
  • Two pieces of 27″x44″ for corrugated side panels
  • Eight pieces of 2″x4″x24″ for wooden top plate support
  • Two pieces of 1″x6″x50″ for the short wooden top plate
  • Two pieces of 1″x6″x91.5″ for the long wooden top plate

Remember, these specifications are used to build a 4’x8′ raised garden bed. So, if you want one of a different size, consider adjusting these accordingly.

Step 2: Assemble Top And Bottom Frames

Use screws to secure long and short frame boards together to create right angles. You can drill pilot holes in the boards first for easier fixation.

Step 3: Build Vertical Pillars

Use the screws to attach the two 2″x4″x20″ pieces. Then, continue making the other three pillars in the same way.

Step 4: Attach The Pillars To The Top And Bottom Frame

Attach the vertical pillars to the bottom frame by pre-drilling the holes first. When drilling holes, position the drill at an angle of about 45 degrees. Next, put the screws into these holes to secure the verticals to the bottom frame.

For the top frames, flip the frame over and do the same as above.

After that, use a diagonal ruler to check that the sides are perpendicular to each other.

Step 5: Add The Corrugated Metal

Attach corrugated panels onto the inside using some screws.

Step 6: Place Top Plate Pieces

Because the size of the top plates is quite large, you need support from eight pieces of 2″x4″x24″ to make the top plate more stable.

Fix the support top plates around the inside of the bed. Then, pre-drill and secure the top plates to the box.

Now, you can relax and enjoy your metal raised garden beds.

Tips For Maintaining Metal Planter Boxes

The instructions above must have shown you how to make one yourself. It’s time to know how to keep the boxes in their best form so that you won’t waste money and effort making another one!

Avoid Acidic Soil

To prevent small amounts of zinc from seeping into the soil, do not use highly acidic soils. Acid is the main reason why your metal raised garden beds will deteriorate over time.

Use Liners

Use liners to prevent contact between the soil and inside the planters if you grow plants that need acidic soil.

Add Mulch

Mulch not only prevents weed growth but also slows down water loss for your plants.

Choose The Right Location

You should find a place that does not receive sunlight all day to settle and help the plants not wither under the hot sun.

The Bottom Line

With the above step-by-step instruction, we believe you can easily make your own metal raised garden beds. Using this type, you can rest assured that you’re investing wisely in your greens! Hope you will soon have a beautiful and fertile garden.
