There is green staining on my swing. Is this normal?

Our round pole swing sets are made from whole tree trunks which are stripped of bark, trimmed to size and pressure treated to ensure their longevity.

The green substance on the wooden pole, which can be mistaken for mould, is actually a chemical reaction between the wood sap and the chemical used in the pressure treatment.

It is completely harmless and we like to think it adds to the natural charm.
