What are the best types of metal for planter boxes?

  • Copper - Copper planter boxes may be solid copper units or fiberglass planters with real copper coating. Large copper planter boxes patina over time into a stunning greyish blue. They'll naturally deter pesky insects, too.
  • Wrought Iron - It comes powder coated with rust resistance and a sophisticated look.
  • Aluminum - Also powder coated, it’s rust-proof and durable with the ability to stand the test of time.

How to select the right size metal planter boxes?

Visually, your large metal planter box should be half your plant's height. With this design principle, a 7" box will look great with a 14" plant. This rule applies regardless of how many plants a container will hold. In general, make use of planter boxes that allow a lot of room to accommodate a root system. There must also be room for growth. What's more, there's a need for an inch of breathing room above the soil for watering.

Your plant-to-container ratio must be just right. Placing a large plant inside a small container will cramp the plant's root development. A container that is too large for a plant will look awkward as well. A large container will hold so much soil as well that moisture retention will be problem, especially for tiny root balls. Since you're thinking of buying large metal planter boxes, only consider using them with plants that grow bigger over time.

What are the most important features of metal planter boxes?


Drainage is crucial to every plant. As a matter of fact, there are more plants that die from overwatering as opposed to underwatering. As water fills all the air pockets that are essential for root development, a plant will die quickly. Unless you are growing a water garden that's containerized, make sure that you only use the planter box that has drainage holes. There are planter boxes with removable plugs. Others will only come with indicators where holes need to be drilled.

You may find a beautiful large metal planter box without any holes. It is often referred to as a cachepot. You can still use this stunning pot, but make sure you don't place the plant in it directly. What you should do instead is to place the plant in a smaller container with drainage holes. Then, place an inverted saucer inside your cachepot to elevate the plant and allow it to be far from the excess water collected within the cachepot.

Protective Coating

Large metal planter boxes may look stunning on their own, but they can be affected by humidity, moisture, and heat that can cause the soil inside the containers to dry out. Drying out, of course, hinders the roots of plants to grow. If you will be choosing metal planter boxes, make sure that they come with non-toxic rust coating in order to protect your planters from rusting and extreme corrosion and ensure the soil doesn't dry out.
