Metal Planter FAQs
Are metal planters good for plants?
Metal pots and planters can look great in your garden, but you do have to be careful that they don’t overheat. Excessive heat can take a toll on the roots of your plants, so if you love the look of metal planters, there are a few things you can do to keep your plants in good condition.
Choose light-coloured metal planters to reflect heat
Use a large metal planter to dissipate heat faster
Sanitise the planter to prevent disease from spreading
Add an inner lining to dissipate heat
Keep the potting soil moist and cool
Place the metal planter in shady areas of your garden
Do you need to line a metal planter?
Lining a metal planter has multiple benefits. Lining the planter with plastic can protect the roots of your plant from overheating, which is very common with metal planters. Leaving a gap between the plastic liner and the inside of the metal container will help to circulate air, allow moisture to evaporate, and ensure heat can dissipate.
Secondly, lining the metal planter with a substance such as waterproof foam can help to seal the metal planter from water damage and therefore, prevent a build-up of rust.
Will metal planters rust?

It will usually take a few months of use to oxidise and produce a layer of rust. The corten steel plant pot will need to be exposed to the atmosphere and all different types of wet and dry weather to fully develop. Within 4-5 months, your planter will have changed colour for a fully authentic appearance.

Are corten steel planters safe for vegetables?
Not only do they provide a beautiful and simple style to your garden, corten steel planters can also be a great option to grow certain vegetables. it is safe to grow vegetable plants andseeds in planters made from weathering steel. Corten steel warms up quicker than other materials, is low maintenance, and is also resistant to weather exposure. Vegetables that need warmer climates to flourish would be best placed in corten steel plant pots, for example, tomatoes and peppers. Just make sure the pots have good drainage for any rust runoff.
How do you care for corten steel?
One of the best things about corten steel is its ability to naturally age with almost no maintenance and aftercare. Because the rust will naturally form, no treatment is required to help it get to that stage. You can, however, clean it with a sturdy brush whenever it gets dirty.
