Popular building materials now used to make modular raised garden beds are corrugated metal or aluminum zinc magnesium galvanized metal. In addition to the sturdy structures that can be made from this material, it is also a popular choice for gardening beginners because of its unique look in the garden.
If you're interested in trying Aluzinc - magnesium galvanized steel for your raised garden bed, you may be asking yourself if this is a safe choice for growing an organic garden. Just like any other gardener, the last thing you want to experience is growing crops that are unhealthy and pose a health risk to you and your family.
Below, you'll learn more about this type of material and whether it's a good fit for your raised garden bed. You'll learn why more and more people are choosing this material and why it's becoming more and more popular among gardeners.
Can you use corrugated sheet metal to build a modular raised garden bed?
A common question that beginners have when building modular raised garden beds is whether it is safe to use aluminum-zinc-magnesium galvanized sheet or corrugated steel to grow plants in a vegetable garden.
Well, the answer is yes. They are safe for gardening. Zinc coatings used on metal surfaces need to break down the acid before they can start seeping into the soil.
Since the pH of most garden soils is neutral, zinc has little effect on your garden. In addition, zinc is an important plant micronutrient that is often part of the soil.
Should you be concerned about chemicals leaching into the soil and reaching your plants?
Unlike the proverbial leaching of chemicals into the soil and the use of treated wood, aluminum-zinc-magnesium galvanized steel is different. Yes, they are coated with chemicals, but the chemicals present do not harm the health of the plants and the people who eat them.
As mentioned earlier, zinc is an important mineral and small amounts are recommended. Remember, these were used as watering troughs and were used before plastic or AlZnMg galvanized pipes hit the market. Can be used to build modular raised garden beds, but not cookware. This is because when it comes in contact with any acidic food, it can cause serious health risks.
Why is there an increasing interest in using metal in modular raised garden beds?
The main reason why aluminum magnesium galvanized steel, or corrugated steel, is gaining popularity in modular raised garden beds is that it lasts longer than wood. In addition, there are the following reasons:
Many people want to invest as wisely as possible in their modular raised garden beds, so they usually opt for something that will last longer and withstand environmental changes. Rather than using pressure-treated wood, which of course soaks chemicals into the soil, aluminum-zinc-magnesium-galvanized raised garden beds are the best option that can last for decades.
Depending on how you organize your garden, this material can enhance the appearance of your garden and give off an industrial look. Another advantage of this material is that it does not easily shrink or expand.
You don't have to paint or oil the surface because it's durable enough, but you can choose to paint it. If you want to enhance the aesthetics of these containers, be sure to use safe paint.
After preparing your modular raised garden beds, make sure each bed is filled with pH-neutral and well-draining soil. Shallow layers are easy to fill quickly, but deeper beds require extra material to fill.
Should you try corrugated metal for a modular raised garden bed?
There are many reasons why you should try this material on a raised garden bed for the reasons above. Be careful with the parts you will use. Try to choose new ones or ones without rust or scratches.
Zinc used for steel is a protective layer that prevents steel from rusting when wet. However, scratches on the surface of the steel mean there is a place where rust can start. This can cause damage and affect plant health in the long run. It will also affect the appearance of the raised garden bed.
Corrugated steel raised garden beds are great containers for gardening. Plants are known to grow well in these modular raised garden beds to avoid overbending. Yes, zinc may be leached due to long-term exposure to changes in water and soil acidity levels. However, it will only leach a small amount, which is actually safe.
Understanding Plants' Relationship with Zinc
It is assumed that zinc may penetrate into the soil within a certain period of time. However, higher concentrations are most likely to occur in the areas closest to the steel.
You must understand that plants do not necessarily absorb all the nutrients present in the soil. Many factors in the soil can affect the ability of plants to absorb these nutrients.
You can easily determine if your plant is out of balance and if it's ingesting more than it needs because it doesn't look healthy and isn't growing adequately. If you choose to grow your plants in corrugated containers and you notice that they look healthy and are growing accordingly, then you have nothing to worry about.
