Zinc Planters FAQs

• How do zinc planters work?

  Otherwise known as galvanised steel planters, they are created through electrogalvanisation – a process that bonds a layer of zinc to steel to protect it against corrosion. This makes the zinc planter a durable and reliable plant pot. 

• Will zinc planters rust?

  Although zinc isn't completely rust-proof, it does corrode much slower than other metals. At Primrose, zinc plant pots have been electroplated to protect them against rust and corrosion, however, you should be careful to avoid scratching your planter as it will scrape off the zinc coating and allow rust in. In the event it is scratched and scraped, you can apply rust-resistant paint on the inside and outside of the plant pot to prevent this from happening. To help extend its pristine condition, a protective spray or sealant could be used on the planter to protect it even further.

• How long do zinc planters last?

  Because of the durability of the material, when looked after and cared for properly, zinc plant pots last you a long period of time in normal conditions. If in good condition, yours could last a few decades. We offer a range of high-quality containers designed to last you a significant period of time.

• Do you need to line a zinc planter?

  As they are made from metal, zinc containers can overheat, so plant liner can help avoid this. Using a liner also prevents the soil from being washed out and will make it easier to remove or relocate your plants.

  You can use plastic or moss to line your planter. Moss liner is ideal as it allows water to seep through. Just make sure there are drainage holes to avoid drowning the roots. 

• How to clean zinc planters

  A simple mixture of vinegar and water or lemon juice can keep your zinc planter looking fantastic and good as new. Just gently wash it with a sponge and dry it thoroughly with a clean dry towel.
