Wooden Raised Beds - Rotting

Hi ,

When I first got my lotty about 4 years ago I had some wood which I made raised beds out of.  I have noticed that the wood is starting to decay and that the soil in the beds has white mould in it  if you dig into it .  I first noticed this on the Raspberries but thought it might be natural to Rasps?

Will the mould comming of the wood degards the soil or harm the plants?  Should I just replace the wood?

If it's a fungus that eats dead wood it's not likely to be much of a danger to living plants....i have the same kind of thing in my raised beds occasionally. As Nij says, if we don't want wood treatments near our food, then this is the price we pay - unless we have access to planks of much more resilient wood like alder or oak

I've noticed one of my neighbours has a raised bed made from the plastic 'planks' that are used to fence off roadworks...

I have some thick UPVC stuff for window surrounds (were 'offcuts' at 10 foot each and were free from the local window makers) as yet they have only been used for a small lettuce bed - I need more to do all my bed
