Are all Natural barks the same?
By Ben Parrot - Landscape Gardener & Amateur Geologist
Overview
Play area bark, otherwise known as playground bark, is a well-graded, pine bark-based decorative aggregate that is widely used. When certified, it is suitable for use around all play equipment, including climbing frames and slides, when it is laid to the correct minimum depth.
Garden bark is a generic term that can cover many types and grades of bark product that may not meet the stringent requirements of British standards required for fall safety protection. We cover the differences in this article about play area safety bark.
Just a quick message regarding our newest addition – the 'Pebble Picker' tool – now accessible in the sidebar or menu. It facilitates effortless browsing and selection of decorative aggregates, categorised by colour and type.
Key Takeaways
Play Grade Bark vs. Regular Garden Bark
Play safe bark is a type of bark for play surfaces which must meet the requirements of BS EN 1176. It is generally free from hardwood chip. As a Loose Impact Absorbing Surface (LIAS), it must be applied with a layer thickness exceeding the amount determined through testing to attain the specified critical fall height. We provide the regulation depths, below.
Play Grade Bark
Generally speaking, play-grade bark is a hard-wearing pine-based material graded to a finer density in order to make it more impact-resistant. This is by design to ensure a softer, safer environment that's suitable for children. It is also screened to remove as many sharp pieces and dust for increased safety. Bark is also a natural product, giving it an advantage over recycled rubber play bark where potential toxicity from leachates are a concern for parents.
We have a dedicated play bark product page that provides a deep dive into the various products available for purchase. Any brand of bark product we recommend will always display its certification for everyone's peace of mind.
Regular Garden Bark
On the other hand, garden bark is a general term for a bark material primarily used for mulching and decorative purposes. In the linked article, we attempt to demystify the different types of bark mulch available. However, there are products retailed as 'garden bark' that may also be compliant and safely used for play areas.
While it is also true that bark may NOT have to be compliant in order to be used safely for play areas, it is safest to use play grade bark, and we only recommend it for play areas. Therefore, the use of any other type of bark is solely at the parent's discretion.

Other Applications for Play Area Bark
Using playground bark for play surfaces can mean the difference between safety and peril when the inevitable falls occur. However, it can also be used around the garden for mulching and decorative purposes.
Garden Borders and Flower Beds
Play area bark isn't just useful in play areas. They can also be used in flower beds and borders, too. Bark chippings for play areas aid in moisture retention and also suppress weeds, making them very helpful in all of these applications. Aside from these benefits, the play area bark chips will also nourish your soil and improve soil structure as they slowly break down. In most cases, this means that your plants will thrive.
However, it is important to keep in mind that pine bark is generally acidic, rating between 4.5-5.5 pH. This means that certain alkaline soil loving plants may have their growth stunted, depending on many factors. So, our advice is to keep an eye out, and occasionally monitor the soil pH around such plants.
