Are Metal Planters better than Wooden Planters

Planters are a great alternative to traditional in-ground gardening.  It’s a much more convenient and manageable way to grow plants and vegetables, with options to re-purpose, and move around, whenever you fancy.  They are ideal for areas that have poor soil quality, or limited space.  They can be used on patios, balconies or rooftops, and come in many sizes and styles to suit your needs and space.  Additionally they provide better drainage and soil aeration.  All this allows you to customise your garden to however best fits your requirements. 

It just remains the long-standing question of….  metal or wood?!   Lets break it down.

Design
Metal planters tend to have a more streamlined design that goes along with the metal material. For instance, you can’t really sit comfortably on the edges of a raised metal planter as you tend to your crops, which you may do with a wooden planter, which sometimes incorporates benches into them too.  Wooden planters can also have ornate patterns etched into them, with interlocking timbers etc creating a specific ‘look’ that may suit your garden.  Metal planters are much more simplistic in appearance, and can just blend into their designated space without any intrusion, or focus being taken off the plant it holds.  However, the great thing with a metal planter is that you can powder coat it into any colour of your choosing.  Powder coating provides a solid colour that does not fade in sunlight, and can be any colour of the rainbow…. In fact powder coating can be done in many special effect paints too, such as bronze, gold and manganese.  This layer of paint also provides a brilliant level of protection that you don’t get from hand painting your product.

 

Cost

Traditionally, metal planters have been seen as the more expensive option.  However in recent years, this has changed, and become less of an issue, with more options on the market.  Metal planters do have an initial cost that may be higher than the wooden planters you can pick up in your local DIY store, however we must remember the quality of material used, and many readily available wooden planters are only made of soft wood which may only last a couple of years.  However as metal does not rot or decay over time, you have a longer lasting gardening solutions that justifies any initial cost.

 

Maintenance

When planters are delivered, due to the nature of them being welded, metal planters are already fully assembled and painted.  Wooden planters however, may need some small amount of construction, and nearly always a level of protective coating applied.   The positive to this, is that you can choose a stain that you are already using in the garden so it all blends in, but this is not an option that everyone wants to do.  Wooden planters will however require this ongoing level of maintenance, to ensure that they do not rot, and last as long as possible. 

Metal planters are powder coated - giving them a great layer of protection that lasts its lifetime.  This full layer of protection keeps that resistant to weathering and rusting.  However, be mindful that some companies only powder coat the external surface, which does not protect against rust on the internals.  When fully powder coated, the only maintenance that metal requires is giving the surfaces a quick clean occasionally, with a soft cloth, and some mild dish soap in water. 

The other great thing with metal, is that you can drastically change their appearance if you require, but using a local powder coating company to respray. 

 

Temperature and Insulation
There is a debate about the risk of overheating with metal raised beds, but to date, I have not found any issues.  The outside of your metal raised bed may feel warm to the touch on a hot day, but this should not worry you as there is not enough energy to heat the whole bed to the extent that plants or roots are at risk.

Wooden planters have the benefit that as wood is a natural insulator, it will help keep the soil at a relatively consistent temperature, and retain more heat at cooler times of the year.

Conclusion

A conclusion would be that metal raised beds are typically more durable than wooden alternatives. They resist rot and insect damage and can last for many years, even decades, with minimal maintenance.  Although the initial cost may be higher, they are more cost-effective in the long term due to their durability, and minimal maintenance.

Ultimately, the best option for your raised garden beds will depend on your individual needs and preferences as well as the specific conditions of your garden.
