Is it ok to use pressure treated timber to make raised beds?

Hi, has any one used pressure treated timber to make a raised bed/ground level bed? Is it ok to use when growing veggies on an allotment?

Many Thanks.

    Yes it's fine as the chemicals used to preserve the wood these days are safe.  If you use untreated wood it has to be much thicker as it will quickly rot.  Even pressure-treated timber can have a short life when in contact with constantly wet soil - mine tend to last for between 5 and 10 years on clay soil.

    A trowel in the hand is worth a thousand lost under a bush.
