6 Guaranteed Drawbacks To Metal Planters
Metal planters are frequently touted as a fantastic option, but before you stock up, there are a few disadvantages you should be aware of.
Metal and flowers seem to go against each other because metal is so industrial and flowers are so beautiful, but this appearance can sometimes be effective.
Many are drawn to the modern, cotemporary aesthetic metal planters made of copper, galvanized zinc or cast iron offer. Yet, there are a lot of negatives to metal planters that exceed cosmetic appearances. The many problems with metal planters are eliminated by our specifically created resin-based planters, which can be made to mimic the appearance of any material.
Before going with metal planters keep these 6 limitations in mind…
- Heat Is Drawn to Metal, Cooking Plant Roots
- Some metal finishes are damaged by fertilizer salts.
- Risks to Your Health From Metal Planters
- Rust Possibility Is High
- Heavy Metal
- Metal Is Impermeable.
1. Heat Is Drawn to Metal, Cooking Plant Roots
The fact that metal planters attract and absorb a lot of heat is one of the primary problems with the material. As a result, the soil and roots of your plant grow warmer than they should be, frequently leading to the roots entirely overheating from direct sunlight. The inadequate insulation of metal planters makes this process worse and worse. You will need to add some additional insulation, such as clay or a plastic pot liner, to assist avoid root damage, however these materials can cause other problems.
2. Some metal finishes are damaged by fertilizer salts.
Fertilizer salts naturally harm some of the many different types of finishes that are available for metals. In other words, some planters aren’t even designed to withstand exposure to soil, even though they are promoted as planters.
3. Risks to Your Health From Metal Planters
Unquestionably hazardous to soil are vintage lead planters. Galvanized steel planters may emit zinc into the soil, which some people believe could be hazardous to edible food, plants, and soil. This is another reason why some people are against using them. Some claim that because it would take years for the zinc to affect the soil, the plants and edibles there would already be extinct by the time it did.
Acidic plants pose the greatest threat because the acid breaks down zinc, enabling larger concentrations to leak into the environment. It is ultimately a contentious issue with a variety of opposing viewpoints. The best course of action is to completely avoid it so that you won’t have to worry about it.
4. Rust Possibility Is High
Metal is one of the first materials that comes to mind when you think of rust. This is due to the fact that metal rusts easily, and your metal planters won’t be any different. Planters frequently come into contact with a lot of water, which causes them to rust more quickly.
To stop your planters from degrading quickly, you might need to apply a non-toxic rust inhibitor if you live somewhere with a lot of rainfall or humid subtropical weather. If not, they must be protected from the elements, such as inside or under a reliable cover.
5. Heavy Metal
No, we don’t refer to the genre of rock music known as heavy metal; rather, we imply that your metal planters will be HEAVY! Weight varies depending on the type of metal. For example, if you choose cast iron, your planters will be too hefty for balcony gardens and too heavy for you to carry by yourself.
6. Metal Is Impermeable.
Since metal is nonporous, it won’t naturally drain. In other words, if you overwater your plants even little, the water will start to collect and accumulate at the planter’s base. Your roots could end up being a rotten, moldy mess as a result. All types of germs are attracted to standing water, so you should really try to prevent this. To aid release this water buildup, make sure your metal planter has some drainage holes at the bottom.
A resin self-draining planter is your best option if you want healthy plants.
